WTF!?! 370Z is 90PS/litre and even the early 350Z was 80PS/litre
Yeah, maybe if you take the book values, rather than what the cars actually dyno at. Anyway, I'm still not wrong, and it was a 2 second calculation in my head, so being all of 5bhp out on the 350Z is hardly a disaster! I never noticed It was a 370 the OP had.
