cheers

Id say about 140mph on the stright and level. Evo got a 182 to 139mph (or it worked out to about that) on a test track oval a 172 wont be that far off.

One German forum user has hit the limiter on a big hill in 5th which is about 150mph I think.

Roamers has 212hp though and an ~8k redline so is capable of more speed.

I think he said it would be capable of ~155mph give a long road.

My is on the standard box and hit the rev limiter in 5th at 7k ish. Its not as high as the 1st 3 gears. GPS confirmed that yeah the gearbox is limited to around a genuine 143mph.

Roamer must have an uprated ECU to GPS at 148. TBs would require an uprated ECU anyway??

 

[Ian_182]

i didnt think gearboxes had a limiter? just the engine

The limit to the gearbox is just what the engine can give, the stock engine is redlined at 7.2k I think so thats the maximum theoretical speed its capable of. But drag etc means it wont reach the engine redline in on the straights.

Roamers runs an external ecu though but the stock 172 ecu can be remapped togive the car higer revs. An R-Sport ecu gives you an 8k redline but the car wont hit the redline in top with just the R-Sport ecu due to drag.

A standard 172 ECU will allow the engine to run to 7200rpm in 1st, 2nd, and 3rd only. 4th and 5th have a 7k rpm limit for whatever reason. As for not reaching the readline on the straights, yes it will. People have video/photo evidence to prove this , if the 172 ran out of revs at its max power (6500rpm roughly), then 130ish would be the max speed of the 172/Cup.

Book top speed is 134mph iirc.

Ive had mine at 130 gps varified and seamed to have more to give.
