Very nice descriptions and without naming names i am sure the answers above are correct.Yes my initial post was what makes the rapid increase in the rpm's..some may think dumbest thread this winter but i enjoyd it..thanks for the replies and i wasnt arguing with him he brought this to me because he likes to ask guys this when there talkin cars at work and he walks off leaving them in deep discussion and it gets talked about for a couple days.

I kinda figured what you meant, and was just playing with semantics.
So what we want to know now is what increases rpm.
combustion is the answer, how you get it to be more efficient is another question. Anyone else?
