My Nova 16v Project

[novashed]

awesome glad to hear you did so well, your enthusiasm pays off well mate, real pitty you could wipe the floor with .04 sec over the fiat but hey

[tom reid]

Well done Olly, look forward to the vids/pics

[trackdaynova]

in my usual style, I'll be doing a seperate TOTB Photo thread, but because this is my build diary, here are a couple of mine in static form.

i am awaiting some pics from NeilShawPhotography of me on the handling circuit, and will post when I have them :)

What a superb weekend ! what a SUPERB result for Olz :)

The car looked savage on the track, nothing compares to a shot of gas and I would imagine you will now agree lol ok it doesn't last forever but youir car was ballistic on the roadtest we done before you left, so much so I nearly crapped myself and had to turn the gas off I was so scared lol

Good to see a few familiar faces there today although I'm a bit dissapointed in myself for not meeting the others who came to give Olly support.

Brilliant weekend again though, camping was great, sorry for stealing a space in your tent Olz but cheers for covering me up when I moaned about being cold at some time this morning lol

Can't wait to see some videos

[Jonlem]

Oh and also thanks for the kind words about the install, with a bit more time it would of been far tidier but we ran out of time and at the end of the day it just had to work, which it did :)

[trackdaynova]

Not one to waste any time... we have vids lol

[peester]

car does sound possesed now.. looks like it takes you for the ride, lol.

[trackdaynova]

ack - just watched those back and the quality is shockingly bad

would anyone be interested in downloaded full res PAL version if i upload them to webspace so they could be right click/ save as?

[Welsh Dan]

Yes please.

[Jonlem]

Sounds properly on it in the handling video, loving it

[vaughanmc]

Sounds absolutely amazing!!!!!!!

[hybridturbo]

Great results lads

[nova ian]

As said on the phone Olly, Well done on the results :D

Well chuffed for you and glad the car went so well for you, looks like our hardwork payed off :thumb:

Catch you later mate

[Adam Moran]

Good stuff Olly!

With all the sprints you'll do before the next TOTB id say you could have that 1st place next year.

Really really well done mate, you deserve the respect

Hopfully see you soon

Ad

[m17tty]

congrats on the results olly,sorry i couldnt be there to see you do the day.Vids look cool and sound like a monster and goes like **** off a shovel!!!

[burgo]

So, I came 2nd place overall in the FWD Handling Group, which I'm over the moon about with a 54.00s run, and the winner did a 53.97s run, a mear 0.03s better. A 450bhp Fiat Coupe who has won for the past 5 years running :( so I didn't do too bad, right?
to drive half way home just for the crack. No tyre pressure nor suspension was tweaked, it was literally as I took it. you should be far more than happy with that, fecking awesome result

[Adam]

Sounds even more awesome in the vids than normal,Lol.
100bhp straight in? :cool:

12.8 @114 is good going for concrete?
Probably low to mid 12 at pod..


Good going :thumb:
You can really notice in that 1/4 vid, just how short your 2nd/3rd/4th gears are too

[trackdaynova]

Thanks for the comments everyone, it seems I shouldn't be so happy with my performance after all, according to Chip lol

Ad - yup, 100bhp, straight in, no controller, nos virgin

[Adam]

Chips commenting on the engines lack of power(compared to other competitors), and not your performance itself?

"And Olly was REALLY driving the **** off his car, I dont care if it was his first time or not, he was pedalling as hard as he could and his car simply didnt have the pace to compete, it needs at least another 50bhp on that circuit to stand a chance!"

[dhdev (Oli)]

I hope it came across on MIG that I was fighting your side Olly. I genuinely think Chip was barking up the wrong tree, saying you need an LET to be competitive :roll:

[Martin]

lol its not all about power tbh, driver skills have a lot more tod with it, hence why i was watchin the HC more the Drag strip, straight lines are for girls...

u did very well olly fella.. like said, few more sprints you'l be 1st

[Adam]

Straights are all about power though to a certain extent :thumb:

[Adam]

Just seen the full res vids, top work Olly.
That concrete surface loosk pretty ****e, handling wise too.
So you did very well indeed :thumb:

[The Simps]

some great driving there Olz and a cracking result to come 2nd wth it being ur 1st time at TOTB!

I can see how the extra power would be good on those straight bits but only if you're able to shave it off again quick for the next corner.

I do however think people right off a LET nova for a trackday car far too easily. I've seen how a p2 nova with diff and sccr can go!

[Lee]

I hope it came across on MIG that I was fighting your side Olly. I genuinely think Chip was barking up the wrong tree, saying you need an LET to be competitive :roll:
I dont believe it! Chip never barks up the wrong tree!!

Nice work Olly. Buy a LET and you've copped out IMO lol

[Dar]

I dont believe it! Chip never barks up the wrong tree!!

Nice work Olly. Buy a LET and you've copped out IMO lol

Nah buy a LET and stick it in the back :thumb:
Nice results! Top driving.

[dave@ag]

Well done on the results, car looking and going good!:thumb:

[nathan.]

:eek: Fantastic results olly. Well done mate! :thumb:

[NovaNeil]

Very well done Olly :thumb: Really enjoyed watching you and the rest of the Team out in action yesterday! Was loving your maximum attack driving style on the handling circuit although Oli (DHDev) kept on chunting that a small block would of done better :roll: haha. ;)

Well done again! Great result

Neil

[Lee]

Oli (DHDev) kept on chunting that a small block would of done better :roll:

I challenge Oli to sling a 100 shot through his puny engine and see what happens lol

[trackdaynova]

whoa! thanks for all the comments... i'm chuffed to bits.

i shall host my other videos aswell, not just my fastest - just to see what/ where i did stuff differently etc

thanks for the pics!

did anyone get any external footage of my car? i know how it felt, with the 100shot kicking in, but i wanna see it from the outside lol

[Jonlem]

Simps- a phase 2 let will have less power and similar torque to Olly yet will be miles heavier.

A well sorted let might destroy Olly on the long tracks but IMO it wouldn't stand a chance on a tight twisty track like that.

Nice pics above, LOVING those videos.

[dhdev (Oli)]

An external view of one of Olly's handling runs, the quality isn't great as it was done on an digital camera, not a video camera. http://i41.photobucket.com/albums/e296/dhdev/th_MOV00639.jpg (http://s41.photobucket.com/albums/e296/dhdev/?action=view&current=MOV00639.flv)

[The Simps]

Simps- a phase 2 let will have less power and similar torque to Olly yet will be miles heavier.



How much power is Olly running? A good shape p2 should punch out around 260bhp and 280lbft. Have seen higher.

Ho will it be miles heavier? the turbo doesn't weigh that much more than a std manifold surely?

Shaun Larnder's mustard SR is running P2 and a hybrid putting out 290bhp. Its also got diff and sccr quaife and thats really quick with the box.

Having never driven a car with NOS does it really balance the power difference between high power TBs vs Turbo?



A well sorted let might destroy Olly on the long tracks but IMO it wouldn't stand a chance on a tight twisty track like that.


What are the other cars in the fwd class running? na or turbo?

[dhdev (Oli)]

The extra weight of a turbo (turbo, intercooler, pipework etc) is all carried out the front of the engine, which is obviously as detrimental to handling as it could be!

[trackdaynova]

Oli - that vid is awesome thanks bud... got any of my 54s run? :)

Cheers for posting it up - anyone know how I save it?

[The Simps]

Yeah, but seriously, intercooler is not that heavy! turbo manifold compared to standard is a bit more but surely not enough to make a mahoosive difference. No more than the big block/small block debate.

[Lee]

Big power LETS will be on F28's as well. That doesn't help matters. I think youll be surprised at the difference if you add all the extra bits up.

[burgo]

Yeah, but seriously, intercooler is not that heavy! turbo manifold compared to standard is a bit more but surely not enough to make a mahoosive difference. No more than the big block/small block debate.simps, olly changed his windows from 3mm to 2mm to save some extra weight. do you really think he wants a big old turbo hanging off the front?. as for how much power no one knows

[Jonlem]

How much power is Olly running? A good shape p2 should punch out around 260bhp and 280lbft. Have seen higher.

Well over 260hp, much nearer to 280hp imo

Ho will it be miles heavier? the turbo doesn't weigh that much more than a std manifold surely?

Combined with a F28 its WAY heavier

Shaun Larnder's mustard SR is running P2 and a hybrid putting out 290bhp. Its also got diff and sccr quaife and thats really quick with the box.

Personally I dont rate a sccr on a let, a KKK is well out of puff after 5500rpm so if Olz bolted one to his he'd spend his life out of the powerband, feeling fast and being fast are 2 different things

Having never driven a car with NOS does it really balance the power difference between high power TBs vs Turbo?

Look at Gaz'd Corsa for a example, clearly gets up and fooks off, with a touch over 300hp its nearly as quick as a Tigra with 505hp as it has useable power, if you use a controller you can have it deliver the nitrous as smoothly or as aggressive as you like


What are the other cars in the fwd class running? na or turbo?

NA and Turbo, Fiat in question was 400hp Turbo

I guarantee with the power Olz has he could beat that with a more tracktime

[trackdaynova]

And before anyone says it - lol

This time next year I will be 15kg lighter in person too

[Lee]

And before anyone says it - lol

This time next year I will be 15kg lighter in person too

Now thats a mammoth poo! Make sure you take a pic!

[m17tty]

Now thats a mammoth poo! Make sure you take a pic!

:roll: lol

[AlexW]

Your going to be racing naked?!

[m17tty]

thats a great video oli (dhdev),god i wish i could have been there!!

[Martin]

And before anyone says it - lol

This time next year I will be 15kg lighter in person too

Told ya Spedos Would of been a good idea, and imagine the tan ;):cool:

[trackdaynova]

lol

[Stoo]

Nice going Olllllzzzz

[Adam]

Liking the outside vid, sounds cool as

[dhdev (Oli)]

Olz can't text as i'm at work. But I'll have a check on the cam later for more vids, i think i just have one of you against the Polo on the 1/4 and I think the vid I posted of the handling is before you started using the Nos.

[trackdaynova]

Thanks Oli - any would be greatly appreciated, and I'll add them on here...

For now, been looking around and finding some more photos of my baby. Thanks to Neil Shaw (Orange Peel), and Mark Shaw (Bicco) for the following shots respectively

Is it worth adding a 5th bonnet pin?

[trackdaynova]

lol I thought the same, but thats what you get, and thats what I was warned about when getting the uuuuber light bonnet, with very little bracing.

another bonnet pin = weight, so no lol

[Welsh Dan]

Any carbon bonnet pin gen? lol.

[Adam]

Only just noticed the bonnet,Lol

[m17tty]

lol at bonnet!!! get a 5th pin loz! its gonna weigh sweet f*ck all and is cheaper than a new bonnet when a gust of wind hits it and wrecks it!

[LiquidPug]

So does anyone know where team VX actually placed on Sunday? TOTB website only lists to 3rd

[m17tty]

Just an idea olly but have you thought about doing something like this to aid air to the t/bs when youve got the foam filter on? The bit at the top in the middle.its on a corsa on another site(pinched from daveb at c/s;) )
http://i139.photobucket.com/albums/q306/m17tty/IMAG0198.jpg

[trackdaynova]

Steve - www.VauxSport.com (http://www.VauxSport.com) for all TOTB news mate :)

[trackdaynova]

Matt,

Corsas are different engine bays to Novas, as Novas experience massive updraft from up behind the block, and behind the slotted scuttle panel when driving along, so the cool air comes from under the bay, upwards, even moreso when firewall is removed like mine is...

That was proven when I had the bonnet jacked up at the back, driving down the dual carriage way, it was lifting in the middle, at the back massively!

So therefore, it would be of no benefit for me to do what Dave has done.

I need to have words with him, regarding his tumble dryer pipework, as it needs to be somewhat more direct than looping over and under bits and bobs :thumb:

Should I want downdraft air intake, i'd fit a monteray bonnet vent again, ala my white one :)

[LiquidPug]

On a side note (Olly)... "STEVE...BOLTS!" lol
How was I supposed to know!!!! lol

[trackdaynova]

ermmm because I've never seen plug covers held in miraculously with no bolts.... durrr lol

[trackdaynova]

If I could leave you more rep, I would - but when I try - it says I have to spread it around before giving you any more!

Thank you so much for these... really appreciate the time and faffing you've done to get them to me.

I know how tedious they are... watching now! :)

[trackdaynova]

Jeeeeesus that nitrous sounds so vicious on the quarter mile, proper hisses away, along with gearbox - love it!

Gagging to see the 100shot runs now lol

[dhdev (Oli)]

Just a shame that the camera doesn't pick up the blue flames out the exhaust and blurred vision lol

[trackdaynova]

[chav moment] blue flames??? how cool... lets hope Span's mini dv version has them ;) lol[/chav moment]

the rivets fell out my floorplan and everything :(

[dhdev (Oli)]

Its ok, just slam the laptop and tell it to shut up then drop it down a gear :tard:

It did sound cool on gas :cool:

[Jonlem]

Jeeeeesus that nitrous sounds so vicious on the quarter mile, proper hisses away, along with gearbox - love it!

Gagging to see the 100shot runs now lol

The hissing is the Polo ;)

I can't even hear your car over it lol

Circuit videos on a 100 shot need putting up lol :thumb:

[Martin]

thaqt polo sounded liek a jet lol

[trackdaynova]

m177ty - what I was talking about, about updraft... whilst I was sorting my vid against the above Polo... need I say more lol

I've upped the brightness on the video purposely so you could see when I actived the nitrous (left toggle), and so you could see the tacho, and the lack of revs drop in between each gear :)

Enjoy (ps: 50shot)

Towards the bottom right hand corner of the video window, click "watch in high quality" its soooo much clearer/ better :)

**** me that bonnet twists lol

[trackdaynova]

so much nozzzzz it twisted the chassis as it came off the line lol

[scottydogg38]

this thread is being very helpful 2 my project, thanks

[Adam]

Christ, that bonnet was proper "in the air" lol

Top vids.
What were you triggering the nitrous off? TPS signal? Or just manually switching it?

Edit-Just seen you were running it off a toggle switch. Where did you have the switch mounted??

[trackdaynova]

Toggle switch was to activate the nitrous, but then the trigger was on the TPS, so nitrous jetted @ 75%+ throttle only, or 4volts on MBE.

Safe way to drive with it I think, especially for a newb'

[fearless]

Whats the plans after the gearbox has gone ?? You going all hi tech with a sequential !!!!!!!


Dave

[trackdaynova]

Hey Dave - was great to finally meet you at the weekend - thanks for coming to introduce yourself :)

Nope, definately no sequential on the cards unfortunately, I'm down grading to a standard F20 to free up some monies.

Did you hang around all day on Sunday?

[fearless]

Yep -stayed all day - I've got a few snaps of you in action - not up to your standard but I'll post them up later


Dave

Dave

[t45_ste]

You raced somebody pulling a caravan lol

[trackdaynova]

Considering they're taken on Auto - they are mega impressive

Just checked last PMs between us two, and you did get the camera I suggested :D Glad it works out so well :thumb:

Nick - sorry pal - will reply now

[trackdaynova]

You raced somebody pulling a caravan lolyup lol he missed a gear and I still lost lol

[trackdaynova]

Well - massive thanks for Spanish for his persistance, here is an external video of my 54.00s lap, which I absolutely love - thanks so much for sorting this for me Rob!

Makes me feel a little better about how it was, as it looks faster from the outside, than it does on the inside... loving me bouncing off the rev limiter on Nitrous creating blowbacks!

http://uk.youtube.com/watch?v=-CVj0U_u1zY

Enjoy!

[t45_ste]

That looks so quick off the line:thumb:

Liking the tags on the video lol fire rat free zonelol

Good effort there alround - looked like the NOS worked out well for you:)

[Martin]

nice one olly..

[Adam]

Great vid. Sounds superb :cool:

[fearless]

Only taken on my digi camera so not fantastic quality

Probably very similar to Robs as I was behind him but sat up on Martin Kelsons Scafolding Tower :thumb:

[trackdaynova]

nice one Dave - thats another great video! :)

Is that also taken on the Panasonic camera? as thats cracking quality (when you click high res on You Tube) for something that isn't 'designed' to do videos :thumb:

[vaughanmc]

I see your selling your gearbox mate, what kind of box you getting for it next ? :)

Awsome build thread by the way as well

[trackdaynova]

Against popular belief, I am seriously not getting anything naughty, not sequential or anything like that, just standard box :)

[fearless]

So what other upgrades have you planned - once you've got all the money in your pocket ?

[m17tty]

So what other upgrades have you planned - once you've got all the money in your pocket ?

I reckon a tow bar,subaru bonnet vent and an air horn?

[novashed]

hhhmmm what upgrade for around a grand??

[The Simps]

why de-grade to a standard box tho olly?

also, was you ever running a diff in that box?

[trackdaynova]

Simps - yep, the SCCR box currently has a ZF Plate diff in it, which I fell in love with which is why I'm keeping that.

I'd never go back to an ATB personally :thumb:

[novashed]

so whats the dosh going towards as you really rate that box mate?

[The Simps]

I'll remember that about the diff mate cheers.

p.s. well dodged on the "why you going to standard box" q! lol

[trackdaynova]

lol @ dodging questions...

All will be reveiled, but I just wanna say just yet - but I can guarantee you that I'm not going to anything naughty lol

[LiquidPug]

but I can guarantee you that I'm not going to anything naughty
for once :p

[novashed]

for once :p

second that.:thumb:

[Jonlem]

Olly is fitting Rick Drapers engine, its no secret

[trackdaynova]

After speaking with Lee & nova ian for a rather long period of time last night, I've decided not to sell my box after all, and they made me realise the mistake I would have made had I have gone through with it, and how I would have regretted it.

To get over my annoyance with the box, which is the fact it's a PITA to travel anywhere, due to the gearing, I've decided I'm going to follow what Chris Tunnicliffe did to his to make his more bearable on the road, and travelling to and from circuits.

I will be fitting a helical 5th gear which means no more whining for hours on end, better fuel consumption (on a run) to boot, and less strain on the block so no more sitting at 4.2krpm at 70mph.

I called Quaife (http://www.quaife.co.uk/) today who were more than helpful when discussing my options, so I used their speed calculator to work out what I wanted to achieve.

Firstly found out the rolling circumference of a Toyo 888, 195-50-15 tyre using AlloyWheels.com (http://www.alloywheels.com/tyrecalc.asp), which works out at 1809.56mm

So here is my current box details:



Gearbox:- My current gearbox
FD Ratio:- 3.764
Tyre:- Toyo Proxe 888, 195-50-15
----------------------------------------------------------
Top Gear gives 17.234 MPH/1000 RPM and a top speed of 133.565 MPH at 7750 RPM

Engine speeds in top gear:-
30 MPH = 1741 RPM 40 MPH = 2321 RPM 50 MPH = 2901 RPM 60 MPH = 3481 RPM
70 MPH = 4262 RPM 80 MPH = 4842 RPM 90 MPH = 5422 RPM 100 MPH = 5802 RPM

Top Speed in 1 gear = 54.688 MPH
And changes into 2 gear at 5370 RPM dropping 2380 RPM
Top Speed in 2 gear = 78.925 MPH
And changes into 3 gear at 6253 RPM dropping 1497 RPM
Top Speed in 3 gear = 97.823 MPH
And changes into 4 gear at 6495 RPM dropping 1255 RPM
Top Speed in 4 gear = 116.729 MPH
And changes into 5 gear at 6773 RPM dropping 977 RPM
Top Speed in 5 gear = 133.565 MPH



Using good old Wikipedia (http://en.wikipedia.org/wiki/F20) for information, the most common F20 gearbox found, will have a 3.55 FD, and a 5th gear ratio of 0.89:1 (currently using a straight cut quaife 1.040 5th gear)

Should I go for that option, and fit a final drive and 5th gear from a standard F20 box, it will give me these figures



Gearbox:- Ideal gearbox
FD Ratio:- 3.55
Tyre:- Toyo Proxe 888, 195-50-15
----------------------------------------------------------
Top Gear gives 21.353 MPH/1000 RPM and a top speed of 165.485 MPH at 7750 RPM

Top Speed in 4 gear = 123.766 MPH
And changes into 5 gear at 5796 RPM dropping 1954 RPM
Top Speed in 5 gear = 165.485 MPH




Alternatively, I can scrap changing the Final Drive, from 3.55, and just keep my current 3.764, and change 5th gear to a 0.89:1 from a standard F20, to get these results

By doing the above, obviously I remain the same acceleration as I currently have, but have a longer top speed, and a quiet 5th gear... but lower RPM in in 5th at each speed

decisions decisions...

I do have a F18WR sitting here doing nothing, which has a 3.55 final drive, but I've just done some research and the 5th ratio is 0.74:1 lol which would give me the best part of 3k drop when changing into 5th. This isn't an option, due to me using 5th on most circuits, altho that does come with a possible 176mph apparently if I had enough power to get me there lol lol lol

[Adam]

Just changing 5th sounds like the best idea to me.(to 0.89 ratio)

[novashed]

id go for changing the 5th as adam said.

As it will give you more scope for a more powerful engine yet still retains a nice drop of the revs on every gearchange.

I'd still like to put 2 identicals cars on track one with sccr and one with a F20 to see how they fair against each other considering what we worked out.

I'd say the swap in FD will definately make a big difference though and the helical 5th won't make it so aggressive on the drive to the ring next year ;) (as you have no excuse not to come now lol)

[trackdaynova]

The ring trip is the main reason I'm doing it lol

Obviously among wanting to go Coombe, Oulton, Brands etc :)

[chris gsi]

or you could leave it as it is and stick it on your trailer the lazy option:D

[Adam]

Get Combe booked Olly! :)

[trackdaynova]

lol not booking Combe, unless I can get a refund on Trax as I can't make both :)

[trackdaynova]

^^ sorry, those ratios are what? - the ideal ratios for performance??
like computer game cheats/ 'best setups' explained?? lol

[Welsh Dan]

How long does it take to swap 5th?

[Adam]

Not long.
End plate off, few circlips and pull (or get a puller on it if its reluctant to move)

[LiquidPug]

[trackdaynova]

lol lol can't believe you actually took a pic and hosted it yourself lol lol

[LiquidPug]

meh, why not! lol

[The Simps]

5th gear swap sounds like a logical idea to me mate!

[trackdaynova]

Yep - it will be done eventually, probably over winter now to be honest - as I want to get a few trackdays in between now and the end of the year - so time is precious...

Rockingham and Brands Hatch trackday semi-booked, just need to confirm both!

MOT next week :)

[Ste L]

MOT next week :)

bloody hell, has it been a year already since it was built :eek:


dont seam that long ago

[trackdaynova]

Well, MOT expired on Friday 1st August, wasn't planning on re-insuring and re-taxing it, but I did lol

I'm well chuffed with the amount of done in the car within its first year of being finally complete... it's gone through some changes within, too.

Oh - Ste, bought another set of Cesaros lol

[Ernie]

looking good and still going stronge fella.
thumbs up from me and keep up the good work.

[LiquidPug]

Oh - Ste, bought another set of Cesaros lol Are you building the first 16 wheel Nova or what :confused: - should change your name to trackdaycesaros :thumb:

[trackdaynova]

lol, thats three sets and two spares... so 14 in total...

these are staying silver though, as I love the look of my car here

http://i136.photobucket.com/albums/q161/neocapture/Bobb01.jpg

regardless of it being on slabs, I think its mainly because they're silver and there is more definition

[Ernie]

It reminds me of Dans beast in that pic.

[trackdaynova]

Is anyone interested in joining me on either of the following:

Saturday 18th October - Rockingham International - All Day - Open Pit - £175
Sunday 9th November - Donington Park National - All Day - Open Pit - £179

[adam c]

the donington park one sounds good!especially with it being on a sunday and with donington being fairly central.who's that with?i think i may have to sign up for it:cool:

[Paul]

If the Rockingham one is still available when I get back from Ibiza then I may have to book that one up!

[trackdaynova]

bahhh i might do both lol

both bargains, both my favourite tracks...

i'll call it a year after then probably

[Paul]

What happened to the Brands Hatch idea, nice and local for me!

[trackdaynova]

oh yeah... thats £99 open pit all day... in November I think I can remember...

that too then, and then seriously that'll be it before Xmas :thumb:

[Paul]

I should be able to do that one deffo. SOunds cool + nice and cheap :)

PS: what tyres do you run on all of your wheels Olly?

[trackdaynova]

Black Cesaros - Legal Toyo 888, 195-50-15 (Inters)

Black Cesaros - Uniroyal RainSports, 195-45-15 (Wets)

Tigra 5 spokes - Illegal Toyo 888, 195-50-15 (Dry)

2 spare Black Cesaros - Full Dunlop slicks, 185-550-15

Silver Cesaros - none as yet lol

[Adam]

Might be interested in Donny

[nathan.]

I might give rockingham a go

[Jonlem]

27th December, Donny no noise limits day, ALWAYS a superb day out, just look at the entries before you book into expert class lol

[ben21]

Gonna try and get to one of these days dude, see how my student funds go once Uni starts.

[trackdaynova]

Nice one chaps - nice to see some interest... albeit almost a perfect split between Rockingham & Donington.

:)

[Stoo]

i will fetch the teg to at least one o f those TDs

[Benn]

French? eek.

[Jonlem]

French? eek.

Someones got to like them I suppose lol lol :thumb:

[trackdaynova]

OK, so my car has now been road legal for a year, or just over - the MOT has expired so it's time to take it again.

Booked it in for mid week - so we'll see what goes - I have no horn button, so hopefully I'll be in the car when he asks me to press it, so i can just touch the two wires together lol

Other than that, for some unbeknown reason, I washed and polished it the other day, paying particulary attention to doors, under sides, shuts, and gaps... very odd

Skies were nice so I took a pic... booooorrrrrrrrrrrrrrrrrrrring
http://i136.photobucket.com/albums/q161/neocapture/nc0999.jpg

Door shuts polished... wtf olly?! (pic number 1000 in my thread, yay!)

Thats it - gotta be my best update so far to date

[dhdev (Oli)]

You ****ing bufty boy lol

[t45_ste]

Get it on a detailing websitelol You need some back to black :thumb:

[Benn]

Shuts are very clean.. Why have you taped the drill holes up?

[Adam]

Should pass mot easily. LOL @ the horn though lol
Fit a cheap maplin push to make button..... Cost about 3quid

[Ernie]

It should MOT fine fella see you at combe.

[trackdaynova]

Cheers lads, its on Wednesday so I'll let you know if it goes through OK lol

Awaits "missing rear seats, missing rear seat restraints" advisories lol

Benn - what you mean taped up drill holes? where abouts?

[chris gsi]

put it on your trailer if it fails as my mot ran out in oct 06:thumb:

[corsakid]

if you lived close i could have done you an MOT LOL

[vaughanmc]

Benn - what you mean taped up drill holes? where abouts?

The drainage holes on the bottom of the door ? I think he means

[trackdaynova]

they're not taped up? lol thats how mine are... you can see the insides of the doors through the slotted holes in the bottom...

[trackdaynova]

Passed MOT, no advisories... straaaaaaaight through :cool:

[vaughanmc]

Nice one :)

Do they not have anything to say about it not having back seats ?

[Lee]

Nice one :)

Do they not have anything to say about it not having back seats ?

MOT's dont look for actual things in a car, they check whatever's there is legal.

ie. It will fail if you have a bald spare tyre, but will pass if there is no spare at all :)

[Adam]

What did you do with the horn situation?

[trackdaynova]

Vaughan - see what Lee said, he's correct for once

Adam - I went to local motorist centre, travelled back 8 years in time, looked at all the chavvy buttons, bought a brushed stainless horn button about the size of a 5p, for £4.99, and wired it up, and positioned it in the standard location for what used to be the manual choke :cool:

So - do we talk 'Combe Convoy' in here? PS: MSN

[Lee]

PS: MSN

Would if you were online you massive poofter lol

[trackdaynova]

oh yeah - lol forgot about that...

am nowz

[vaughanmc]

lol Cheers mate wasn't too sure - Iain was speaking to me on MSN about it

Kind of cleared it up for me, cheers :)

[Adam]

Aye, buying a button was the best idea for the horn.

My msn was fooked sorry, will be on later though :)

[trackdaynova]

So, the Nova passed the yearly nasty exam with no warnings, which is good news...

Now on with more spending.

Yesterday, I collected 6x full race slicks that I bought from eBay

I now have 6x Michelin Radial S9B, 19/57-15 which will be going on my newly acquired silver Cesaros.

I'm pretty much all set for Combe, obviously these won't be coming with me as Action Days don't allow full slicks, but they're there for when I next do Donny and Rockingham.

Just need to use the last half a tank of laughing gas I have, so I can remove the kit prior to Combe, so thats going to be done tomorrow.

[m17tty]

Olly, a bit off topic but never the less id like to say a big thankyou for the help you gave me on the PAS rack and pipes etc on the 206 today(Sat).I really do appreciate it and owe you one for it too.Cheers buddy!

:thumb: :thumb: :thumb:

[trackdaynova]

No problem Matt - anytime, anywhere - just hollar :)

So, the Nova had its final bit of laughing gas today, Me & the wife went out for a blast on gas, then came back and Ste (LiquidPug) jumped in for a go in the scarey seat... certainly wasn't as "wow" it was at TOTB which is very strange, not much of a kick at all considering the 100shot jets were still in.

Hey ho, kinda glad of that, after driving it today for the first time since TOTB properly (apart from tinkle to the MOT station and back) I can safely say I think the car is quick enough with gas for now :)

Michelin S9Bs are now on the silver Cesaros, altho I probably won't be using these until next year now when we have some warm days again.

Just on the verge of booking onto the Donny/Oct and Rockingham/Nov days, as then we have the PNG Karting in December :)

Thanks Steve for all your help today with removing the Nitrous bits and bobs, and the tyre changing...

I can now go back to being anti-nitrous after trying it out lol jk

[trackdaynova]

OK so I did what I said above, altho different locations as I want to try out different tracks all over the UK.

So up and coming booked on and paid for events now are:

Saturday 6th September - Castle Combe Euro Fest Action Day (4x sessions)
Sunday 26th October - Cadwell Park, Full Day, Open Pit
Sunday 9th November - Donington Park, Full Day, Open Pit

Anyone intersted in joining me for either?

[Benn]

Olly what time are you out at combe?
Wanna test me new lens ;)

[Ste L]

when you gonna do oulton?

will defo come watch, and pinch a passenger ride when you do it :)

[LiquidPug]

Thanks Steve for all your help today with removing the Nitrous bits and bobs, and the tyre changing...


As always, no problem mate - just collecting some 'Hewitt' tokens for when I need a hand :thumb:

[trackdaynova]

Benn, I'm out on track at 10:00, 13:00 and 15:15 so far... and I'll buy some more tickets on the day with any luck :) Some new pics would be awesome mate, have one of the ones you took last time at Combe on the wall in my garage :)

Ste, It'll be early next year - probably my January one.

Now my car has been on the road a year, done some working out - I've managed to do at least a trackday, or a sprint every month of the year between August 07 and August 08, sometimes twice.

I have one for Sept, Oct, Nov, possibly the noisey day at Donny in Dec... and hopefully I can continue to do so in 2009 :) until it blows up :thumb:

[Ste L]

Ste, It'll be early next year - probably my January one.


ace, defo will come watch, give me a chance to practice with the camera too :thumb:

[Benn]

10? Hope i'll see that, i'm out at 9:45, prob wont still be there at 1pm tho...

[Adam]

Good stuff Olly.
The pressure in the nitrous bottle will probably have been dropping down as it was running low....which could explain not giving the kind of boost it gave at totb.?
I may get that Donny trackday booked :)

Hopefully you can sort a 4th session for Combe, because i so need a passenger ride in this :cool:

[trackdaynova]

lol so 4th session is yours, and 5th is Stuart's then lol

Bottle heater was on, and pressure on Nitrous gauge was 975psi, which is optimum, well, 950psi is optimum, anything over 1000psi is deemed unsafe, and at TOTB, we were constantly between 1050 and 1100 psi lol, without the bottle heater on lol

[Prey]

Donnington - yay! If your not minding people milling about randomly I'll def come down to this one as I think I need to see this car in the flesh pal!

[trackdaynova]

Hey Alan, yep - no problem mate - the more, the merrier!

Although with the time of year, bring a waterproof coat, but fingers crossed for blistering sunshine so I can try out my S9Bs lol

[Adam]

Olly-Who have you booked Donny through on the 9th?

[trackdaynova]

Both days booked through: http://www.trackdays.co.uk/ :)

[trackdaynova]

So tonight I have wired up my digital SPA speedo, which sits infront of my standard mechanical speedo, was a bit of a nightmare getting it all neat and hiding all the wires but all done successfully, just need to mount the reed switch and magnetic pickup onto either the brake disk or CV joint.

Also lowered my bonnet slightly on all four bonnet pins, as I was aware of it lifting under hard acceleration, so i reduced the gap between the top of the headlights & grill, and the bonnet...

Hopefully it'll reduce this: (another cracking shot by Neil)

http://i136.photobucket.com/albums/q161/neocapture/nc1003.jpg


EDIT: random tripodage in a straight line lol

[Benn]

Ooo any gen on the digi speedo?
Love the tripod pic. See msn too.

[trackdaynova]

This is the speedo I have: http://www.spa-uk.co.uk/design/speedo.asp

Tripod is a bit random, completely uneven and bumpy surface, alongside stiffer and stiff suspension means occasional loss of traction

[Benn]

Funk me thats got a price tag.

[adam c]

when you coming up north to try out croft then:D ?

[Jonlem]

Good to see its all going well Olz.

When Ben had that issue with his bonnet he fitted a very lightweight ally brace inside the bonnet, hardly effected the weight and sorted the bonnets issues out

[trackdaynova]

Thanks JB - so did the ally brace go the complete width of the bonnet? or just the centre half?

Update today, fitted reed switch / electric pickup & magnet for SPA Speedo, and took the camera out with me to update some pictures on recent additions to the car.

So the inside of the car got resprayed due to it being scratched, and upon exit of Nitrous bottle, my passenger navi-footplate was installed again, after being bent back into shape, the back part was like a big U shape where people have been pressing rather hard under braking lol

Looks really clean and purposeful inside mate, well done :)

I know what you mean about the foot-rest, I've seen me bury my feet in the passenger foot-well a couple of times when I'm out and about

[trackdaynova]

So on with the funky bit

I removed the securing screw from the centre of the brake disk ready to see where I can mount the magnet & reed switch
http://i136.photobucket.com/albums/q161/neocapture/nc1013.jpg

To find that they're an identical thread - bonus
http://i136.photobucket.com/albums/q161/neocapture/nc1014.jpg

Looked at the back of the hub to see if the thread went all the way through, as I'd need it on the rear of the disk... and bingo
http://i136.photobucket.com/albums/q161/neocapture/nc1015.jpg

Lightly screwed it in to check the pitch was the same, and it was
http://i136.photobucket.com/albums/q161/neocapture/nc1017.jpg

Removed the spacers, spiggots, disks and calipers to get access to mount the reed
http://i136.photobucket.com/albums/q161/neocapture/nc1016.jpg

Also managed to use the original threads for where the brake disk backing plate mounts, to make it uber neat and easy
http://i136.photobucket.com/albums/q161/neocapture/nc1018.jpg

Spaced the pickup out with 2x 10mm nuts on the thread, to make the pickup closer, so there were no in accuracies, as close as possible before it was touching, tightened it up mega tight
http://i136.photobucket.com/albums/q161/neocapture/nc1019.jpg

All sorted, wired up - and checked it works by just spinning the wheel by hand, it it reads... just gotta calibrate it now, which is easy done
http://i136.photobucket.com/albums/q161/neocapture/nc1020.jpg

[nova ian]

Good work Mr Olly, Dash is looking good with the speedo and shift lights. Love it!

[Adam]

Great stuff. The speedo magnet/pickup looks like factory fit! :cool:

Are those speeods meant to be pretty much 100% accurate then?

The slicks look well on the cesaros too :cool:
How much wheels you got now? lol

[LiquidPug]

Next up a photo of my mint Cesaros with my Michelin S9Bs on them
http://i136.photobucket.com/albums/q161/neocapture/nc1005.jpg

:cool:

Looking good as usual Mr Hewitt

[bozz]

Looks like a mint project mate - all credit to your patience.

[Benn]

Intresting to see your cv joints, that type one touches on my hub/bearing and stops the wheel turning, tastey bbit of kit is that speedo gear.
Tyres look a bit hardcore too.

[m17tty]

God those slicks look the sex!!!!!:thumb:

[trackdaynova]

Thanks for all the nice comments.

Yan - cheers bud, I'm liking it, I've just sourced some black plastic so I can remove the old speedometer/ odometer completely to lose the 'cluttered' look.

Adam - I now have 17 Cesaro alloys (4 sets, plus 1 "spare") and 4x Tigra 5 spokes all with different weather tyres on :)

Well chuffed that I was able to use all the standard holes, other than buzzing a bit of the back of the hub, so the nut sat flush and parallel, everything was top notch and easy :thumb:

SPA claim that the speedo is 99.99999% accurate, due to the fact you measure the circumference of the tyre itself, when it's fitted to the wheel, and inflated, and you input that into the SPA to the nearest MILLIMETRE.

So for others who have the same gauge and run any of these tyres:

195-45-15 Uniroyal Rainsports = 1762mm rolling circumference
195-50-15 Toyo Proxe R888 = 1793mm rolling circumference
19-57/15 Michelin S9B Slicks = 1781mm rolling circumference

Liq - look good eh ;)

[MC]

The circumerence changes alot with tyre wear. :thumb:

[trackdaynova]

sure they do... but still a more accurate speed reading than none, or a gearbox driven one without knowing what size wheels are being run :thumb:

[burgo]

nice neet install of the speedo mr olly. and the slicks on cesaros looks hard core

[LiquidPug]

Liq - look good eh ;)
Defo doing mine now!!!

told you it looked good :D

[Martin]

kool olz likin it

[MC]

sure they do... but still a more accurate speed reading than none, or a gearbox driven one without knowing what size wheels are being run :thumb:

Sorry, not critisizing the product, yes it is very good, just pointing out that the device might be 99.999%, but the input might not be. Still far better than any standard speedo.

[trackdaynova]

Thanks Chaps!

Ste - deffo do yours too :)

Martin - thanks pal

MC - certainly mate, I'm not going to be changing the circumference each time I change the wheels, unless I can be a r s e d lol I'm just looking forward to knowing what speed I'm doing certain corners, especially @ Donny down the craner curves as I know I carry some knots down there - would like a G meter too ideally :)

They are very good coming from years of using one, the differences within the tyre wear to speed related, although not massive, can suprise still lol

Just out of curiosity, when you measered the rolling circumference, are your figures based on a wheel being rolled along the ground/measured it as a circle etc, or the wheel being fitted to the car so the squish of the tyre is taken into account, then rolling it backwards/forwards a number of times to compare and average out (obviously with a mark on the tyre and a mark on the ground at every point the tyre point makes contact).

Only reason for my asking is following on from marks comment, that the speedo is very accurate, but soley dependant on how accurate the input it receives is (also as others my use your settings for road applications)

[trackdaynova]

I did exactly what you said on your second point.

I marked the tyre, with the weight of the car on the tyre I rolled the car forward and back once and marked the floor, only did it twice mind.

It states in the instructions over and over that it is only accurate if you input the details correctly.

There is an auto-calibration setup, whereby you drive along a 1/4mile stretch of road, and it calibrates it itself, however I don't fully understand how that can work...

[LiquidPug]

would like a G meter too ideally :)

Ping-pong ball & pudding bowl? lol

[trackdaynova]

[Gordon Ramsey] ping pong ball, pudding bowl, DONE! [/Gordon Ramsey]

:D

[Dan]

cool, you answered correct :thumb: lol

i think back when we did mine we did an average of ten attempts just to be overly sure. As for the autocalibration lol lol lol lol that never did inspire me with confidence, if that was as easy as it read i would also expect the unit to make me a cup of coffee afterwards

[LiquidPug]

remembered that vid you showed me......no, not that one ;) - the one of the Nurberg with PiP of the home made G-meter!

[trackdaynova]

tell me about it - I felt the same!

maybe I should do a few more tests, but as said I'm not too bothered about it being so accurate that I have to rely on it to read 29.9mph to go through a 30zone speed camera...

i like the fact its a decimal point speedo, ie: 100.7mph lol thats pretty cool.

another thing I could do to test it, is to ride down to Combe with my TomTom sat nav in the car aswell, to see if they both match

[trackdaynova]

remembered that vid you showed me......no, not that one ;) - the one of the Nurberg with PiP of the home made G-meter!the vid i showed you, with a ping pong ball, and a G spot meter... was that not Debbie Does Dallas? no?

[dhdev (Oli)]

I imagine the 1/4mile auto-calibration thingy will be similar to the standard mile at MIRA. I'm guessing you press the button at the start of the 1/4 and press as you cross the end of the 1/4 and it calculates the circumference using the number of rotations it's measured? The 1/4mile would've been chosen as most users will be able to access (RWYB) a quarter mile to do the measurement on.

It does look very factory fit and sooooo lucky that the threads matched up on the pickup!

Was nice to catch up and chat earlier :thumb:

:cool:

[trackdaynova]

Yeah Oli, was lucky that the threads matched... was kinda chuffed, was also nice to meet up, albeit absolutely lashing it down in a McDonalds carpark getting all hot and steamy in the 'barge of love'

Dan - as you had one of these prevously, was it identical? by which I mean - did you have to set the trigger points?

I'm struggling getting it calibrated, it' asking me how my trigger points there are, trigger points being the amount of 'points' that pass the sensor every one revolution of the wheel.

So I entered '01', thinking that the "point" was the magnet, so the magnet passed the sensor once every revolution, but now, apparnently I can do 234mph in first gear lol

The number of 'trigger points' go from 01 - 40... I've now set it to 2, and it looks more like what it should be, ie: 5th gear, 2krpm = 34.9mph... which is about right, but wanna make sure its calibrated correctly.

Can anyone shed any light?

[Dan]

Hmmmmm tbh its been so long ago since i fitted mine (nov 2004) that it doesnt ring any bells tbh, the sensor is of different design but the unit is identical. What i will do is dig out my old instructions tomorrow and have a quick read through and see if it jogs my memory :confused: It makes sense to do such a thing so we must of done something similar but what exactly doesnt spring to mind.......watch this space....

[Stuart]

Bring the instructions tomorrow. I'll have a gander too

[dhdev (Oli)]

Is it not because you have the sensor mounted inline with the direction of rotation, whereas it should be perpendicular to it?

[trackdaynova]

perpendicularbless you.... come again? lol

[burgo]

bless you.... come again? loli assume he means you might need to have it mounted so the magnet passes the end of the sensor and not the length of it

[trackdaynova]

ahh, tis what Stuart also said - but when I was testing it, the sensor didn't "tick" when i stroked the end with the magnet, only when the magnet passed the two lines either side of the word "SENSOR" on the sensor itself, as it wouldn't count the revolutions...

The only other thing I can think of, is that I need to mount the sensor horizontally, as opposed to vertically, which is no biggie... I'll test it properly on the way down to Combe this morning :)

[dhdev (Oli)]

That's what I was saying :thumb: Perpendicular = ''At right angles to''
It'll probably need to be horizontal and having the pickup passing between the lines on the sensor :)

[trackdaynova]

Cheers Ol - I'll try it horizontally and go from there.

So, we travelled down to Chippenham to the Eurofest Action Day at Castle Combe, thoroughly enjoyed myself, was a great fun day out!

As always, here are a couple of photos that were taken of me whilst on track.

First three - thanks to Chris Harrison Photography (http://www.chrisharrison.smugmug.com/)

[vaughanmc]

Looks mega out on the track - Has the bottom of the passenger rear arch had a repair ?

[trackdaynova]

Certainly has :thumb: a poor one at that was done by the old boy who had the car before me

[vaughanmc]

1st time I've ever noticed it lol

I'd love to be passenger in this round a track sometime :)

[Ernie]

You cant beat that bonnet bra fella lol.

[trackdaynova]

isn't it just awesome Chris lol

oh, I found some footage on YouTube from a Golf I think that was out in your session (your car is in the shot) along with the black evo, white scooby and silver scooby... i'll pm you the link :)

[brainsnova]

i take it the bonnet is fibreglass with it bending in the middle.

[Adam]

I'd love to be passenger in this round a track sometime
Oh, trust me, its fooking awesome fun :D lol lol

Great pics there, that Chris Harrison guy took some awesome shots, found a good one of mine by him too :)

Again, cheers for the passenger ride :cool:

[trackdaynova]

Chris certainly knows his away around a camera better than most :thumb:

No problem on the passenger ride, just a shame we couldn't see the full potential due to the wet track, hey - first time I've ever hit a barrier with you in the car lol

Brian - totally mate, just a not very good quality fibreglass bonnet, vert light, very flimsey... hence the need for the tank / gaffer tape

[Ernie]

Im glad mine is the heavy weight type as it came un pinned and still atayed in 1 shape.
Could you send a link to the vid please fella.

[trackdaynova]

PM'd you the link Chris :thumb:

[trackdaynova]

So, I cracked on with the things I said I wanted to get done...

I wanted to lose the clutteredness behind my new SPA gauge here
http://i136.photobucket.com/albums/q161/neocapture/nc1006.jpg

So I removed this completely
http://i136.photobucket.com/albums/q161/neocapture/nc1028.jpg

Got some thin plastic, and sprayed it black, so we'll have this, voila
http://i136.photobucket.com/albums/q161/neocapture/nc1029.jpg

New view from the drivers seat, much better imo
http://i136.photobucket.com/albums/q161/neocapture/nc1030.jpg

New weight saving/ aero dynamic purchase went ahead with my SPA mirrors
http://i136.photobucket.com/albums/q161/neocapture/nc1031.jpg

Old mirrors, 690grams each x 2 = 1380grams total (1.38kgs)
http://i136.photobucket.com/albums/q161/neocapture/nc1032.jpg

New mirrors, 130grams each x 2 = 260grams total, way less than half of the weight of one standard mirror, and more aerodynamic... 1.12kg lost
http://i136.photobucket.com/albums/q161/neocapture/nc1033.jpg

No mirror
http://i136.photobucket.com/albums/q161/neocapture/nc1034.jpg

Template for baseplate that I'll make, also out of thin plastic, or carbon
http://i136.photobucket.com/albums/q161/neocapture/nc1035.jpg

After I came off at Combe and hit the wall (first time ever) bit of t-cut later makes it a distant memory, altho it was awesome at the time... back to o normal!
http://i136.photobucket.com/albums/q161/neocapture/nc1036.jpg

[Ernie]

I wait to see the impact vid mate.
Cheers for the link.I think they felt the same way about some peoples track manors on saturday.

[Adam]

Good stuff.

That wing has cleaned right up, cant even tell now

[Benn]

I have some carbon that would do you base plates perfect... and i didnt know you came off?

Could you not have fitted the spa speedon in that place of the old one? Just built in to the plastic?
