Brilliant, thanks Keith, that's exactly what I had in mind. I like it.Quote:

are you trying to copy some aero mods here Colin? cut down the pressure caught in the wheel well?
Certainly that's where my first thoughts were, but I also like the look of them.Quote:

Anyone got a 3D printer, or know someone who has and would be willing to create some replicas for me?
If you want to drop the pressure in the rear wheel arch, vent the top of the wing, and lose the entirety of the back of it, venting won't do much as there's still a solid surface for the high pressure to sit on, and allowing the air to flow out like that can actually stagnate the flow on the other surfaces, causing the pressure to be higher... sounds backwards but that's kinda just how thermodynamics works lol
Very hard to find an example as they're normally covered, but here, you can imagine it's almost like a large piece of hollow box section behind the wheel well, and that's actually no surfaces behind the wheel, so nowhere for high pressure to build. Early examples didn't have the flat outer panels to smooth flow along the car so it's easier to see, but I can't find an example atm.

edit: http://www.speedhunters.com/2013/02/...r-suzukis-s15/ check this out for aero ideas. Although I would have started with a flat floor and diffuser since that's about 30-60% of where race car downforce comes from and the CoP from doing that is generally quite central.
Lee - any luck finding out about the round nose bearings?Quote:

Did some stuff to the gearbox today, fitted the hydraulic release bearing, and gave it a coat of paint;

I still need to find a round-nose clutch release bearing if anyone knows what the answer for this is (Lee?). Thanks.
Glad to see this is still plodding on, Hopefully we can get back to daily updates soon - One of the best threads IMO
Thank-you for the encouraging words.Quote:

Colin I don't understand what you need when you say round-nose clutch release bearing, because what you've just fitted should be all that's needed to release the clutch once the box is fitted (excluding the bleed union shown below). Unless you're in the realms of that slave cylinder not being long enough to reach the plate?
http://sadpanda.us/images/1721147-73W7UNA.jpg
the style of clutch hes using requires a round nose bearing, as a flat one can damage the spring fingers in the cover.
Colin i have used a flat face bearing on a 7,1/4 sintered race clutch ,not ideal i know but there was no evidence of any damage when it has been apart
Colin, will you be breaking Novas again when you've sorted a unit out?
Glad your still progressing with this, it looked fantastic last year at the Nats ;)
Yes, I have a fair bit of Nova stuff still up in storage in Lincolnshire which I need to bring South and then get sold.Quote:

the guy who was gonna find out for me has let me down sadly, sorry about that, have to say though i agree with jez, i run a flat face on my 7.25 and while you do get a witness mark on the clutch fingers, it hasnt caused me any issues...Quote:

Could you talk me through what you did to make yours? I guess it's from a Vectra?
Is yours a small block gearbox?
Yeah fairly sure it was from an early Vectra; the bleed union just attaches to the top of the hard line from the slave cylinder on a slide clip.
Then it's just a metric male to male union with a female on the end of the braided line; I ditched the rubber standard line.
It's from an F18 (Vectra) onto an F16 (shown).
Thanks, I will have a scout round the local breakers yard and see if I can find one.Quote:

The block has been honed, and there's a set of Omega flat-top pistons ready to go in. The new capacity of the engine will be 999cc, so that's a useful 14cc increase in capacity (!).
New racing-spec valves and springs are waiting to go in, along with a custom Kent camshaft (high-lift, low duration) which has been done specifically for a turbocharged engine. My engine builder has found a head gasket from a Corsa diesel which should be ideal for the job, and is cheap.
The crank and flywheel/clutch assembly has been lightened and balanced.
I now need to pay for a set of custom rods, about £900 apparently, and then there's not a lot else to be done before the engine can all be bolted together.
Now I need to get up to Lincolnshire to collect all the Nova stuff I have in storage, and get on with selling it to raise some cash.........watch this space.
My 1.6 zafira had the same clutch fitting as that so they fit small block boxes as well. Bad news on the engine but cant wait to see what power thr new spec does
Found a clutch bleed in the scrapyard today, and got that fitted up and ready for the Aeroquip hose to it;
http://i285.photobucket.com/albums/l...psde0e60b3.jpg
And did a bit more cutting and playing with the front splitter (not finished yet);
http://i285.photobucket.com/albums/l...ps2af3967c.jpg
I've picked up this slightly bigger fuel tank, I'm not sure if I will use it though;
http://i285.photobucket.com/albums/l...psb13124b7.jpg
http://i285.photobucket.com/albums/l...ps40e08e10.jpg
It's got a built-in fuel pump, and a swirl pot, but is maybe a bit heavy for my needs. I did think it would be nice to have a slightly larger fuel tank for testing, as the current tank is absolutely tiny.
But now I'm thinking I will stick with a small tank and possibly relocate it to the engine bay.
I use a gallon tank in my autograss car which fits where the wiper motor goes.Made of aluminium.Nice and compact,considering I still run a firewall.
Did you do many arm curls?
hahahahaha lol lol lol lol
I expect a lot of people have seen the new issue of 'Total Vauxhall' with the Corsa A drag car from Bulgaria on the cover?
For those that haven't, there's some photos and details here;
http://upg.bg/en/projects/upg-carbon-corsa
It's a very interesting machine, with lots of clever detail.
Naturally with my pursuit of all things lightweight, I was taken with their one-piece carbon fibre front end, as well as the carbon doors and tailgate.
So I've been chatting with the guys in Bulgaria, and they've given me some prices and weights for these bits. The weights are impressive to say the least, but the prices are literally eye-watering......
Definitely something to think about for future developments though, as even on my car it could save me well over 10kg. Mind you, I could probably build up another bodyshell with lightweight T45 rollcage for much the same money!
Havent seen the Cf front up close, there was no way that would ever be cheap.. Or even mid range price...
How tall / heavy are you Colin?
Can understand now why the M600's I build the bodies for cost so much for such a basic supercar lolQuote:

I can do these for you if your interested.
Also the one piece front end was very impressive up close ;-)
The front end was extremely light, on several occasions it was nearly blown over outside our workshop lol
The door hinge was broken on arrival and I believe there is normally a better way to secure the door than using tape but that was the fastest solution at the time, either way it is only an outer skin and weighed less than the polycarbonate window
Hi James.Quote:

As for the front end, I will get one of those if I can ever get some money together. It would be perfect for my car.
Total weight for that is 5kg, which is nice, but the price is £2150. Ouch.
I don't know how much chance you had to study the car, but I'm curious as to what they've done with brakes - any information on those please?
to be fair i dont think those prices are that out of the way, its a lot of work and the materials arent cheap, the savings are huge too. Not saying its a cheap option but for those gains its reasonable bhp/tonne savings.
You're absolutely right Ben.Quote:

More importantly (!), the Nova will soon have a new place to live...the garage I'm building is starting to take shape, with the concrete base laid down, walls starting to go up, and the inspection pit should be with me in a couple of weeks.
Photo update to follow soon......
The new garage for the Nova is now erected.
By tomorrow the front door should be fitted, which will just (!!) leave the roof, the rear door and some of the floor to be done to complete the structural work. So not much then.....
Oh, and then the electrics, lots of sealing up and tidying, and somehow disposing of the huge mound of soil that I excavated in the first place.
Good to hear there has been some progress.
I'll pm you some info on the brake setup from that car shortly.
Thanks James. I found some photos of the front brakes on a 'YouTube' video, it looks very interesting.Quote:

Not very pretty at the moment, but it's a good size and I have lots of plans to make it better when funds allow. Total cost so far (excluding the basework) is well under £500, so I can't complain.
Looking good Colin, you need a gas chamber sticker on that door lol
Yes, that would be suitable.Quote:
