If distance isnt an issue you will hit the limiter in top if you got normal gear ratios.

An RS500 should do 175mph if on standard gearing and has suitable size wheels / tyres / high enough rev limit.

Aren't you on stupid high compression, so NOT surprised . I bet even at 1.8 bar the ignition is in single figures .

With 215s and standard gearing, you would need to pull just over 7200 in fifth to see 175mph.

Staffi,
I was running 3.36 final drive, so only had to pull just over 6500rpm to achieve 172mph (which is where peak power was as well) . Don't forget the RS500 has extra drag due to the rear lip on the boot and top of the wing.
