I will explain myself better: Before the C7 Z06 intro, I might have said that I didn't think a supercharger that small (1.6, 1.7 range)
could move enough air to make 625 HP. But now Chevy has proven that it can. That's a lot of air, and a lot of supercharger RPM. Trying to make 625 HP with a supercharger that size
and a smaller engine only complicates matters with the subsequent higher pressure ratio, inake temperature, cylinder pressure, stress on parts, etc.
But still, 330/349 HP and 625 HP are worlds apart, and I was saying we ought to be able to get closer. I meant it as much as motivation as for technical arguement.
Totally got you now lol.
I can't find concrete valvetrain info but some were saying it's based on the pushrod which makes me think that there is something major going on somewhere in that engine to produce the numbers they claim. Even 2 BIG valves won't flow like a 4 valve, it won't injest like a 3 valve either. There are a million variables though. What is their bore and stroke?
