hi all, sorry if this is a bit long winded...
have been feeling lately that my sti2 isnt as quick as used to be, but was putting this down to me getting used to the car, as ive only had it around 6 months and its my first turbo, but....
decided to give it a blast (on a long stretch of private road ;-)), and think something may be wrong. at 140mph im almost hitting 7000rpm on rev counter, yet when i first got it i remember doing 145mph easily with plenty power left..
anyone any ideas.
what speed do other sti2 (or similar) drivers get at various revs?
lower down, im getting 80 mph at 4000rpm, 100 mph at 5000rpm, 120 mph at 6000rpm...
dont think this is right, but maybe expectin too much ??

any help/advice would be great here as i'm really starting to worry about this

ta, dodge

My STI 2 does about 97 - 98 at 5k in top, so 140 would be hitting rev limiter, also speedo reads slightly fast when the speed gets up. so its probably around 135. Cannot see how you got 145 out of it.

Do not really need the top speed, just good acceleration.

thanks for the reply andy m8, maybe i AM expecting too much out of her!
i did defo get over 140 (on the clock, anyway), but cant remember what the revs were, as it was a while ago.
anyone else with an sti2? whats your top end??

cheers , dodge

hi ive a STI-1 ltd ed, 1-100 jap build, acording to the site, for this car, they are a genuine 150 mph, but no idea at what revs, mine will allways pull to 7000 rpm in top, and on the odd ocation it has hit the limiter in top, sorry i cant help you speed wise, been next to mate,s motors at max rpm and they recon they were showing 150, max hope this helps ,

exesspeed

p.s if yours has the low ratio box, which i think it has, in top they are geared to do 21.8 mph per 1000rpm in 5th, also my rev counter has allready packed up once, and before doing so my rpm, to mph figures were all over the place, but going off your,s mine reads the same, except at 6000 rpm yours reads slower than mine ever has, think my final drive ratio is 4.441, will need to check, any way i rem subaru quoted 21.8 mph per 1000 rpm, so whats 21.8 times 7. =152.6 mph hope this helps too lol

cheers for the reply exesspeed, by all accounts it looks like i'm just being paranoid/ expecting too much maybe. next time im out for a spin i'll check what im getting at various revs in 5th and other gears.

exesspeed

no prob glad i could help, mark

dodge138

hmm, was out for a spin yesterday, and checked my speed at various revs. in 5th gear i'm getting bang on 20mph/1000rpm, so max speed of 145mph. i can live with that, but still worried that something maybe wrong, especially if it should be 21.8mph/1000rpm!
more worrying, i am only getting 85/90mph at 7000rpm in 3rd and 110mph at 7000rpm in 4th! is this right for an (fully de-catted)sti2?
think i will book it in to get checked out, but any advice/ info more than welcome....

cheers, dodge

barge

bet the rolling radius of you tyres is now lower so the top end will be lower

dodge138

standard 16's on the car m8, so i dont think its that...

thanks anyway

Hi - I have an STi version 2 (555 Edition) - Andy555 and I did some testing and I get 100 @ 4600 in 5th although this may be put down to the gearbox

Andy555

I get 100 mph its showing as over 5k, and the speedo is reading a bit fast. So gearing on mine is simililar to RA gearing. No sure about yours Adam, you might have a longer 5th.

dodge138

thanks again for the replies folks!

mine seems to behave much the same as andy's motor, maybe the gearbox varied in the sti2 ?
anyway will book the car in to get checked out soon, and will keep you guys posted on the results!

thanks again, dodge.......

exesspeed

i recon all speedo,s and rev counters can be out by a good 10% wouldnt worry at all

specialx

We have an sti2 with mods and seem to be getting slighly higher results but with kph converters can acuracy be affected?? i will get my bro to run side by side, he has a digital speedo in his rs focus so hopefully get a better idea. we will let you know!

dodge138

thanx again excesspeed, i probably am just being paranoid!!

specialx, i did think about how acurate my convertor is, so maybe this is a factor. will try to confirm how acurate it is, think my old man has a digital speedo in his citroen.

cheers, dodge...

I think Andy and Dodge have got the standard STi version 2 gearbox and I believe I have had the RA gearbox put in...

Can anyone who has a STi Version 2 TypeRA confirm this and tell us their tacho reading @ 100 mph in 5th....
