Well that's cause we aren't talking about RB25's in here
Eg mine on 5's (before bearing let go) did 150rwkw at 3000rpm, 235rwkw at 4000, then maxed the boost (ebc was off and was running off the pussy actuators). It was well on it's way to the same sort of number as before but was making something like 5psi from the start of the run at 1500rpm which is just incredible to drive.
Anyway, back to GTRs, maybe this guy needs to be posting in the 400kw thread
