If this is true, then if the tires are spinning or the clutch is set to slip then each cylinder still only hits 540 times in a quarter mile if it's done in 5.4 secs????

No... if the average engine speed is still 7200rpm, then it would turn over 648 times in 5.4 seconds... nothing up my sleeve, this is just basic math
