Calculating Quarter Mile Times

[StOjA32]

i was just curious to know if there is a way to calculate a "there abouts" quarter mile time using stats from a car... Power & weight.

i do understand it alot comes down to drivers ability traction and so forth... but lets scrap all the variables and leave it down to power and weight... every car has a limit as to how fast it could go down a quarter no matter who drives it.

is there some sort of equation that could calculate something like this?

That site is very inaccurate. I'm assuming weight is in kilos. I put 1450 kg and 200hp at the wheels or flywheel and it says it can run 11s lol.

i'm running 12.5. easy obviously its not gonna be very accurate with only 2 inputs.

guilt toy. what did it spit out for you, compared to your actual time?

[Guilt-Toy]

10.92

I would say that computer program likes me and knows i wanna do a 10 lol

10.9 is fine with me but i should be able to crack a 10 70

hahahaa thats going by 2rismo's estimated weight in pounds he posted in my thread.

mine is pretty close to what times i am expecting so get some slicks and some drag radials and off you go

pretty accurate...i put in my 3300lb to my 670whp and it says 9.91...my best is 9.95 but thats holding the car back by holding 3rd gear...so on a proper run id say a 9.9 flat is on the money.

put my new wheel hosepower in and weight 3300/900 and it says ill run a 8.9...yeehaa

i dont like the fact that it doesnt take into account the drive type, weather its RWD, FWD, 4WD...

I put it in pounds now and it came back 3190lb at 240hpatw running a 13.7sec.

I ran a 14.4 with TCS on so it's pretty accurate actually
