about 135, never actually tried it YET

 

Mine goes off the clock

and certainly goes beyond my bottle lol

 

guide says 150 5 speed 134mph.

when i say guide i mean performance spec on autotrader.

 

It ran at 130mph in 4th the other week on the rollers,5th gear must have more than 5mph right?

 

ive heard 136 - so yea the mid 130's i guess

EDIT - im sure over 136 with tuning can be done - but valves etc are under a lot of strain if you hold that speed...

 

Do you mean the 5th gear ratios theoretical terminal speed? because I think thats up around 180ish, maybe more, I know my mates ibiza ran close to 190 on a 5 speed and ive had mine off the clocks which go up to 160, not by much like, and on a private road obviously.

or the top speed of a standard 1.8T car?

Wouldn't that be the same thing?

A std 1.8t will rev just as much as a mapped one.

 

the 5th gear ratios theoretical terminal speed?

well I'd like to know that if its different

 

Patch... how fast are you doing at 3500RPM??

Nope, the gearbox ratio has a theoretical top speed, which is well above the top speed of a standard car

Think about it, at 134 mph in a standard car, your bouncing off the rev limiter, the gearbox has more to give, otherwise how would a modded car achieve over 150

Your box is good for something like 180-190mph, your car wont do that unless you have about 400BHP and strip it down to almost a bare shell, i know that because thats exactly wehat my mates ibiza ran lol

 

mine stops at 120mph in 4th! [:O] 5th dont do nothing its as if its restricted somehow? as soon as I hit 120 the needle stops dead![N]

 

120 in 4th, you really must have been going for it

 

odd i've had 137mph out of my diesel and it wasnt at top revs (ran out of airstrip to test it on) thought the 1.8t was faster then the 130pd st [*-)]

boom, there you go, find your ratios and whack them in there, itll tell you your boxes terminal speed.

 

patch got 130 in 4th!!

 

It gets there ok just wont go faster than 120!!

 

no im same as joemk4 120 in 4th didnt dare go into fith on this private road everyone goes on about...

So the cars top speed is limited to where the rev limiter is set at?

I might ask Nick to do a top speed run next time i get on the rollers,obviously with restriction doesn't apply.

 

The 02J box with a final drive of 3.389, a 5th ratio of 0.756, a tyre diameter of 25 inches (guestimate) has a terminal speed of 203 mph at 7000 RPM

So there you go, 203 mph, theres more than one kind of 02J box tho, but I assume most 5th and final drives will be similar.

theoretically with no wind you should see near enough to 200 mph in 5th on a RR, rolling resistance is an issue tho, you may not be able to hit the limiter in 5th

 

Does anyone know what a 5 speed1.8t tops out at?

Less than mine! []

However I did wonder the same thing. I noticed it on a few graphs that i've seen.

 

So your doing 100MPH @ 3500RPM???

 

When the rolling road measures the speed does it measure the speed your wheels are going or is it the speed of the rollers. May sound daft but different rolling diameter etc.

Remember speedo error when you get to those sorts of speeds.Think you would need more than 400 horses or a very long private road.
