hi all just doing a bit of research and was wondering what the maximum speed people have clocked in their modified cars and if their is any difference in top end for the classic/newage.

i'll start the ball rolling i run a classic with a 2.1cdb and a uk 6 speed gearbox and recently on a disused runway mine went off the clock at 160mph (not on the road of course). i've now fitted a set of sti clocks that go up to 180mph and am going to have another go.

i'm interested in top speeds of 2.0, 2.1, 2.35 and 2.5 blocks. i'm thinking it is more down to the gearbox than the engine.

has anyone modded their gearbox at all to improve ?

thanks

Arf's car does 160 in fifth gear....



At Elvington, mine is limited to 256 kph, or 156 mph. so no ***** waving here.

But it can get there rather swiftly.....

LOL

yeah down to gearboxes and rev limits,can only rev mine to 6k after that turbo can't keep up and starts losing power/boost so never tried.
soon have 20g fitted tho........things maybe different !!!!!

I have no idea what my 95 wrx can do , but it feels as if its too low geared to go that fast , does any one know what the top speed will be with a rev limit of 7500 on a 95wrx or know the gear ratios , cheers

Top speed is limited by the gearbox ratios. It just takes longer to get there with lower powered cars

andy97 i thought that was the case, i gues the jap cars have a lower top speed than the uk ones due to ratio.

My 95 WRX will pull the limiter in 5th, which is approx 145-150mph.

Never been more than 70mph officer.









in 2nd gear. lol

2.5 classic with 6 speed uk box= 160 clock maxxed out but revs kept rising, so would say approx 170 with 17"s on, on airfield of course

jonboy0373

My 94 wrx type-ra flys all the way to 112 on the limiter and 115 mph without limiter.

ive had 155mph in my 98 uk turbo, its only had a full decat on it then, i was sat at 100 on the m62 till i saw blue flashing lights in my mirrors and then i floored it. not sure if they were after me or not but i made sure i got away.

fkin did mate, came off in hartshead services and theres an access road that you can cut through and get into the town where i live. i arnt gonna put something on here that aint true.

My clocks go to 160 but it revs went abit past that so id say 170ish-----on private land of course this is on a 03 wrx 5 speed.

Had my standard spec d up to 160 mph which may have had a little left ? Now with mods de cat, map, etc. but never tried, probably no faster top end would just get there a bit quicker

had 173 on the road angel, that was running 420bhp on a 2005 sti

greatgonzo

iTrader: (1)

Cool I would have thought a road angel is quite accurate as well being GPRS !!!

Lady-Turbo-Wrx

my 95 wrx unlimited has had 175mph on private road of course

scooby350bhp

got a 97 uk spec, on a private road got up to 165 but had to slow down, sure i cud of easily hit 170, but now got a sti 3 v limited box in now as uk spec box expolded, can only do 155 now on same road but sure gets there hell of alot quicker

Mine was 168mph gps reading with a 40/50mph headwind It had nearly 190mph on the clock

Ginge !

iTrader: (1)

done 155ish alot but takes alot longer from 135 to 155 aswell as the front end gets very light over 140

doubt the car has much more in it

ps: my car is a V3 sti holding 1.3 bar on a mines ecu,,,,,,mapped for jap fuel too

Ciaran

iTrader: (16)

I have had 160mph indicated GPS said 142!!

Surely as somebody has mentioned it is all down to the gearing. So if somebody knows the gearbox ratios for each model then it should be know what the max mph is for those ratios?

how many of you have blown your "standard" engine up doing top speed runs? i did in my old car (repaired under warranty) i was told not to do(by several tuners) sustained speed in 5th and 6th, which i certainly dont do in the car i have now

Ginge !

iTrader: (1)

it all depends how you do it tbh, if your on and off the gas then the car will blow up, if its not banging on the limiter,,,, or making that drone of the revs going up and down a little as the engine cant go any faster then that will also be bad,,, that and if the car aint set up right aswell

ive held my car a few times at 145 to 150 for long periods of time and was fine though tbh i dont feel comfortable doing more than 130ish held these days as im worried im gonna melt the car

Ginge !

iTrader: (1)

you still need the power to get to that speed aswell as the drag of the car too

you can gear a car for 400mph but it aint gonna do that when the cars the shape of a brick, has a huge rear wing with loads of drag,,,,, and lets not get talking about that bonnet scoop

TingTongPJ

iTrader: (24)

drag is very true, i used to have a sti6 large spoiler on the back but since i have gone back to the mid level spoiler it feels much quicker through the gears.

i'm fitting a reverse bonnet scoop next to see what difference that makes.

I understand that but i would imagine that the majority of the cars on here would be able to reach there maximum speed if they had a long enough stretch of private road .

I was just thinking that somebody with all the gear ratios for the different models could work out an approximate top speed. If two cars have the same gearbox but one has a hundred bhp more then they should both have the same top speed but the more powerfull one will get there quicker?

I did touch just over 160 on the Autobahn trying to keep up with a Carrera GT, he was gone so I slowed to 120ish for a few miles then saw him coming back onto the 'bahn after a quick stop
