"rocket scientists" are specialists in V8 combustion engine dynamics


stop! stop! I'm laughing so hard I can't breath!
with those last three posts let's wrap this baby up and send it to SNL for immediate airing
That is the rate that those engines gain revolutions when free reved. The point is they can reach maximum rpm in about .16 seconds from idle speed in the case of the 500 inch hemi fuel engine and about .28 seconds in the case of a rather small 183 cid F1 engine. They free rev at the same rate to maximum rpm which is truly phenomenal especially when you hear either one.
It just shows that there is a lot more to it than component mass.
