What does not change is the math. It works, even for a 9 second car. So, a car that goes 112 mph in the 1/4 can run 11.78 if it's efficient. What makes this hard is when you have street suspension and street tires. Extremely hard!
Math lol....
One day if it ever comes and you're making serious horsepower and all of a sudden your car is a half-second off and you think you blow a cylinder or something you come back home and do the air density calculator for your day and track and find out you were supposed to be going a half second slower. There's so much more to it than your math calculator...
