math formula for car 1/4 mile et's??

[ptsbmw]

The formula is HP= weight / (ET/5.825) ³ which in this case would be:
HP= 2765/ 13.3 seconds/ (5.825) ³… which in this case equates to about 233 Hp as a minimum theoretical requirement to achieve at least a 13.3 second lapsed time.

how the hell do you do this formula to get that answer?? i cant figure it out anyone who knows please pass the knowledge lol thanks im trying to figure out how much power i need to get some good et times at the track thanks again in advance.

I think your equation is a bit off, perhaps you should check the results, again.

um quite simple. you gotta watch the brackets and shit bro.

Hp= 2765/((13.3/5.825) ³)
hp=2765/(2.28)³
hp=2765/12 (around)
hp=230 ISH

Haha, where did that 5.825 come from? What does it stand for?

[Duke]

thats from the formula he provided. Obviously someone did some tests to arrive at that number. Like any other theoretical number. ie. gravity

i dont know where that number (5.825) comes from but is this formula accurate??? i found it off a website and it seems to be close if u do it correctly but i dunno.
