1.3SR 107mph

[DUNOVA.]

Is this good for a 1.3sr or shit???Had mine hit 107 yesterday was well inpressed but I don't think she was.

[pickle]

yeah that is good, i have a 1.4si an got 120mph. i was well huffed too, but i was on my own. and it was on a long stretch.

[novaboy_southwest]

same here i have had bout 115 out of my 1.3sr but was on my own and was driving for 2hours so had rtime to build the spped up

[Ste_Nova]

2 hour run up?

[dave.gsi]

:lol: :lol:

i drove to 115mph in my gsi before bottling it (the car was whinning and felt like it was gonna fall apart lol)

i regularly took my old 1.3sr to 105mph

[novaboy_southwest]

2 hour run up?

u know what i mean (i think) i was driving for ages and thought i would c wot i could get and floored it took a while to get to 115 but got there was whining like a little baby and was redlining it

[mint green nova]

Somehow i got 125 out of my 1.3sr from a standing start in just over a mile!!!!

[Ben]

lol @ the thrid post about the same topic this week.

My GTE will only do 70mph :roll:

[Slatter]

hmm me thinks some speedos ar reading fast ... not the SR ones btw

Ive also seen a 1.2 for sale ... very quick claiming 118 or 120+ mph..

Lol @ some people

And i can honestly say my engine will go no quicker than 115mph i think .... cos of gearbox ratios !

[krobinson]

I got 115 in my white nova runabout, but it was down a very steep hill...lmao

[xX NoVaBoY Xx]

i have had 108 out of my 1.2

[Serialkilla]

I've got a 1.2 carb and i have hit 117mph racing anything that goes for the overtake down the M4. But soon will be hitting greater speeds when i get parts to attach my supercharger. 8)

[DazK]

LOL

never heard of speedo inaccuracy then :roll: :roll: :roll:

[Serialkilla]

My speedo works fine its all the porsche knowlege i've got so i know how to get the most power out of an engine!!!!!! :idea: :idea: :idea:

[DazK]

:lol: :lol: :lol: :lol: :lol: :lol:

[NovaNeil]

Had 126mph on my SR clock.
But my 1.6 Turbo clocked 146mph yestaday on the way back from Santa Pod! :D

[paulwar]

i have had 110mph out of a standard 1.2 nova
the only thing changed new carb and air filter

but it was down a long hill and wind behind me :)

other then that it sits at about 95 easy

[Fergie_sfc]

you probably wont believe me but i swear i aint lyin.

i got 110mph outta my 1.0L with peco BB4 back box, ramair oil breather and K&n carb only. was down hill on way to bournemouth.

but haven't got much near it since, probably goes 90-100 tops.

fergie.

[RobHardyUK]

i can get a (speedo reading) of 110 on the dippy bits on motorways, but only bout 102/3 on flat, mines a 1.2. christ knows what that is real speed, i would say 100ish, mayb bit less. its done 74k, n runs ok, i find 118+ in a 1.2 nova very hard to believe. :roll:

[Slatter]

well i really think none of u have heard that speedos start reading inaccurate figures when you go past 80 - 90 mph

1.2 doing 120 is utter bolloks

And i know that majority of people wont even post on this thread cos they cant be bothered!

This type of thread come up all the time ohh i had 100000000 miles an hour out of my engine with a BB4 and drilled airbox some people just got to face it ******** YOUR SPEEDO ISNT READING PROPERLY******

oh and if you can get 120 out of 1.2 .... how many hours does it take to get there.... lol

[RobHardyUK]

LOL

[nuno_gt]

Of course that speedo's have a little error and that's easy to notice because if you read 110 mph and look to the road, you'll see that the value read in the speedometer doesn't match the current speed you really got. I had clocked mine at +/- 110 mph and, when i saw the "road movement" towards my rear, i noticed very well that's not my real speed.
My real velocity should have been something around 90-100 mph (don' want to bring it down too much). 8)

[mowgli]

look at it like this, an astra 16v @150bhp does maybe 140mph, a nova with the same lump will not do much faster, say 150mph
a nova GTE @ 100 bhp does about 117mph in std form and runs out of revs because of the gearing. It could probably do 130 with long gears.
a 1.3 nova @ 70bhp does about a ton,
So the 1.2 with 55 bhp will struggle to do much more than 90mph
and the 1.0 may manage 85mph
you need double the horsepower to get 50% more speed.

I think that bragging about speed is dangerous. We all speed at some time, even by 1mph, a lot of us don't want to say by how much.

[Slatter]

well said mowgli

I was gonna say that valvers do 140 to 150 max etc

But couldnt be bothered to type it all down :lol: :lol:

[CP]

I'm not so sure its the speedos that are out so much as its them not being zero'd to the wheel size etc. In fact
I took some measurements for Cambridge of my tyres for some tech. gadget he was looking into and there was a considerable difference in the rolling circumference between worn and unworn tyres ( Toyo Prxes T - 1S). I also found that this was affected quite considerably by inflation pressure as well.

If you want to get your highest speeds put your relatively unworn rears on the front and pump them way up to like 35-40 psi. It makes about 4 mph difference on my car - 117 vs 121mph

[mowgli]

Oddly enough, pumping up your tyres before a rolling road session is worth a few pub horsepower. Michelin design tyres that can run higher pressures, and can justifiably claim that they give better fuel economy.
I think the biggest culprit in exaggerated mph is still the digi dash, or using speedometers from the wrong model. fitting 195/55r15s doesn't alter the gearing enough (over 145r13s) to make 30 mph.

[Serialkilla]

My 1.2 had the standard wheels still fitted and original speedo in it. So the wheel size and wrong speedo fitted has not got a facter in the top speed that i said that i had!!!!

[DazK]

and ur engine spec is? :roll:

[dave.gsi]

cough#homemadesupercharger#cough

lmao

[DazK]

:lol: :lol:

im not believing this for crap for 1second

amazing how many people live up to the nova driver stereotype :roll:

[Stuart]

i GPS's my speedo, what it claimed was 100 was acctually 89.6mph lmao

atleats it misreads the safe way to avoid speeding fines ;)



ah yes CP that reminds me i must get on with the 1/4 mile run model.

[Serialkilla]

Its a 1.2 carb it has a bolt on k&n air filter looks like it has had some internal engine mod but not to sure, Janspeed manifold and centre section with a bb4 back box. and that stupid supercharger thing that is at the moment be used to cool the air temp down around the air filter and works pretty well. It did have magnorcore plug leads but they were s@!* i went through 3 lots of spark plugs in a month and it miss fired like hell with new plugs fitted.

[DazK]

:lol: :lol: :lol: @ BB4





















:arrow:

[mowgli]

Like I said before, 117mph would need about 90-95bhp. I did once run a 1.4 with 9.5 to 1 compr but a std 1.2 head +carb with a 3" cold air pipe, with a 4-2-1 system off a 1.3. on a good day on decent fuel it could show 115 on a decent straight (A farmer I know owns an old Bomber Airfield, sadly the runway got dug up). it could see 60 in about 10sec. I had checked the speedo on the M40 measured mile and it read ok.
But I would need a lot of convincing that a 1.2 on a std carb could do that. PMC used to do a 90 bhp kit for the 1.2 and it needed a head job, a cam, a big chimney and a twin choke weber. I'm prepared to be proved wrong.


What Porsche tech. stuff fits on a nova? Could be an interesting toppic on its own.

[Serialkilla]

I'll have to find out by getting parts and trying them if i have any luck i'll start a new topic and tell everyone what will fit.


You could most proberly use injectors from a 944 on a gte/gsi rather than forking out 400 quid or so buying uprated injectors.


Alternatively you could fit a porsche enginge into the car, they do a nice straight 4, a V8 (which is only in a 928) and the rather famous flat-six engine.

Alot of modification will be need though!!!!! :lol: :lol:

[Will]

knock knock

wake up........ its a 1.2

is max 60bhp...........

"prob had some internal work but not sure"

your a porsche technition right, well take it apart and have a look, pmsl

who was the previous owner??

p.s. nova clocks are crap

mine read 135mph at the limiter, load of bollocks imo

[Serialkilla]

vauxhall cheated on the 1.2 they made a few cars with engines that produce 50bhp to get around road tax laws but the engines actually produce 60bhp ish as standard!!!!!!


I've just finshed putting the engine back together after doing big end bearing shells cause No3 piston had to much up and down play in it, and found that it had a different bearing shell to what it should have.


And a porsche engine is a hell alot different to a vauxhall so i don't have any special tools to take it about or put it back!!!!!!!!!

[Paul]

Well if ur some sort of porsche technician, u must kno what mods do what, ie cams kick in at certain rpm, etc. You must know what your looking for, u must have worked on other cars than a porsche, what sort of bearings did they look like, better than some


and found that it had a different bearing shell to what it should have.

1.2's came about 52BHP for the carb and about 43BHP for the SPI, two of my mates have got 1.2 carb and 1.2spi, 1.2 r/r wiv cam showing 58BHP, 1.2i are less cos its only spi not mpi. NEVER 60BHP as standard surely!!!

[Serialkilla]

the only car i've worked on is a porsche and the odd mod on my nova (air filter, Exhaust).

And at the end of the day every engine is built by someone so they are not going to be exactly the same so every engine gives out a different bhp reading.

[Aragorn]

i have NEVER done any work on engines before and dont even own one specific engine tool and managed to strip an old 1400 and build a totally theoretical 1400 engine using various parts from other engines including cylinderhead and injection system from a 1.6 GTE over the last month and it started first time (well as long as u discount the misfiring from a fuel leak caused by a dodgy o-ring)

so you cant really claim you dont have the tools or experiance mate

[Paul]

porsche technician? :?

[Phil_G]

And at the end of the day every engine is built by someone so they are not going to be exactly the same so every engine gives out a different bhp reading.

Hi,

My engine was actually built by a trained monkey called arnold...


Phil

[Stuart]

can he build me an engine too??

[Ben]

lmfao of i couldnt be assed reading it all but picked up the general idea of the conversation....

what a load of bolloks, just as slatter said.

Come on guys be sensible here.

[frog_southampton]

so can some 1 just finnish the post off with a list of bhp for all nova models
and what should be faster...

i had a little race on private track with a 1.4sri (k plate) in my 1.6GTE (F plate) and the sri was quite fast...

what should win the race/

whats the 0-60 times of all these cars?

[frog_southampton]

a nova GTE @ 100 bhp does about 117mph in std form and runs out of revs because of the gearing. It could probably do 130 with long gears.


what gearbox could i use in my GTE to get those longer gears?

[NovaNeil]

F13WR (Wide ratio) of a Corsa Diesel and I think some Astra Diesels. But you may not have enough power to make full use of the long 4th 5th.
Although in my Standard GTE I got 120mph showing on the clock......In 4th! So thats what 10mph? 20mph? up on what 4th can do on the normal F13CR gearbox.

My 1.2 Carb did 88mph on a straight and I ONCE managed 96mph going down a big hill foot to floor for about 5mins!!! And it felt fast.......
Oh how times change.

[novaboy_southwest]

i said at the start of the post that i had 115 in my 1.3sr i know it is not true as many of u lot have said the speedos r crap mine dont regiser till i am doing 30 i know the top speed for a 1.3sr is around the 105 mark so i am will to say i had roughly 105-107

[mowgli]

I got to thinking about the supercharger idea, a 1.2 at 5000rpm on full throttle draws in 3000litres in a minute or 50litres a second. from what I gather, a supercharger pushes about 1.5 times normal air, so that makes it 4500 litres a minute / 75 litres a second is there any commercially available electric fan that can do that? or would it have to be crank driven?

[RobHardyUK]
