Nascar not based on physics? Most technology we have probably trickled down from Nascar. The have spent Billions on research and development on the small block chevy. That's why they did not go LS yet.
They make 650 + h.p. with a 390 cfm carb. Ever see inside a nascar small block?? I have, very interesting. The motor runs over 8000 rpm for hours and lives. You can turn the motor over at the crank with a 3/8 ratchet and 1 finger.
So for you to say a Nascar engineer did not base his findings on physics is a little silly. I think you just set yourself up for another Leech tongue lashing!!
This is why people do not post, it is complicated and you get crap for it. The guys that keep going faster every year are the guy's trying new stuff and different things.
All the bracket racers run the same # every year, they upgrade after the pioneer guys prove something.
