Default Peak power and rev limiters

I just wondered what peak power people have and at what rpm????

Also when does your rev limiter come in????

I know it depends on what mods we have but im just curious really.

Now I havnt hardly revved mine much at all, but according to the power graph I have, my peak power is 322bhp @ 6050 rpm. Torque is around 290 lbft from 3750 upto 5750.

Something i find quite strange is that it seems the rev limiter comes in at about 7500 rpm according to the graph!!!

Do these peaks and rev limit seem normal for that power and torque?

Cheers, Rich.

Graham goode conversion, turbotechnics hybrid, uprated fuel pump, reg, piper cams, water injection, magnex de-cat, pipercross induction.

Just looked at the graph again and limiter seems to be 7250, not 7500 as I first stated.

Standard small turbo rev limits are set at 7k (except for one at 6.8k that I cannot find where it's used).

without the benifit of a proper rolling road power run, I can only guess that my rev limiter is very high (seems well above 7500rpm) and the power feels strong all the way up to the point I change gear. I have not actually gone to the rev limit. - should I try and see what it is?
