its off for me but im still trying to get use to my car. I was running like 18.+ and I was running like 16.9 last year before I left for the desert.

 

theres one calculator out there...i dont remember where...but it uses this function that uses exponents and stuff. its easy but the numbers are really obscure...but it will get within .1 second and 3mph almost every time. its awesome.

 

are you guys factoring in driver weight too? mine was pretty close. it said 14.78 on my before hp numbers, so within about .1-.15, and I had a lazy launch, but its saying 14.3s with my after bolt-on numbers. hmmm, sounds good to me.

 

that says i will run 15's if i get my car down to 1800 pounds(i have a 88' crx HF, 90 HP(stock) but if i were to factor in my 200 pounds it would prolly be at 16)


it sounds about right tho!!

 

a rough estimate for drag racing...every 100 lbs added to the car = about one tenth of ET added on.

I dont really factor anything into mine, since one of the tracks where i ran national events has a scale in the return road...all you have to do is stop and it tells you what the car weighs. all of the big IHRA and NHRA tracks should have a similar setup, since they have random weight checks after qalifiying rounds and such...my exact weight was 3692.9

 

jesus pat put your car on a diet.

 

it said that i would run a 13.88 with a 2100 pound car and 155 hp

 

well the calculator said i would run a 15.7 when i ran a 14.9
