hi guys, can some one please tell me what the top speed is in a tt?? i did search but didnt get what i wanted to know?!!

i know my n/a will go up to 160mph, didnt matter how long the road was, it wont pass, so im guessing that it was it for the poor n/a!!

Didnt get a change to try my new engine!! so just asking?!!:p

 

Is my tt engine limited? to how much? and how can i take limiter out??

 

Thanks

 

Danny

I am told it is quite easy to reach the limiter at 155 even up a gentle slope. :innocent:

 

I thought I read somewhere that with enough room (read miles and miles) on the flat it tops out at about 185 when delimited.

170mph is the absolute maximum you can reach on a stock 6spd supra.

 

192mph is the maximum on a BPU 6spd at 1.25 bar

 

The auto, while having a theoretical higher top speed cannot match these speeds

 

 

Mine did *cough* BPU with mines ECU

i have delimited from 112 mhp limiter so i go over that... but now i know that the ecu is limited for another limit!! so i was asking how can i take the ecu limiter out...

 

There's only one limit at 112MPH... UK specs were limited to 155.

anyone has try a top speed run with a 5 speed gear box on a tt engine???

 

The problem there is you are asking a question that only 2-3 people could possibly answer, none of which are likely to be online right now, have even attempted a top speed run with a decent GPS system, or perhaps even belong to this club.

 

If you're using the NA stock non-LSD diff, the 5spd box it's going to be *far* lower than the TT. The ratios are all wrong for high speed.

 

If you had stock wheels and the non-LSD diff I believe the max at the TT rev limit is 164mph, however you would need the power to pull to the limit, which I seriously doubt a stock TT can do (even with the 6spd, my stock TT was a very long way off the limit). If you get more than 155mph on a gps I'd be amazed.
