Jerry: are you the same Jerry Clayton that campaigned the Keeling-Clayton cars back in the early '70s? I was in diapers at the time so didn't have an appreciation for the sport in those days....
Anyhow, I wanted to let this one die but I'll venture one last illustration (my own personal character flaw of trying to get the last word):
Take a motor, any motor, put it on a stand in a shop and run it 4.5 seconds at 7200rpm, how many times did it turn over? Answer: 540... how many times did your timing light flash? Answer: 270
Take the same motor put it on a rocket ship to the moon... same deal run it at 7200rpm for 4.5 seconds. How many times did the motor turn over?
Take the same motor put in a top fuel dragster...
etc, etc, etc....
I know there is inherent slippage and I don't think lockup ever occurs in a TFD. The point I'm trying to make is that it doesn't matter... how many times does the motor turn over in 4.5 seconds?
I don't know how big TFD tires are but lets figure 35" for the sake of argument (I know even at that they grow considerably as they spin so let's not go there)...
Simplified model: circumference = 35"*pi = 110" = 9'2"
Quarter mile = 1320'
Revolutions of this hypothetical tire (with 100% traction) in a 1/4 mile = 144
All this is beside the point of how many times the motor turns over...
Sorry to beat a dead horse one more time...
