Wallace Racing HP Calculator For 1/8th Mile

I think this shows a little high for our trucks, but it's the only one out there that I know of.

Re: 1/8 mile calculators

Alright, if my truck weighs 8200 (I am sure it wieghs more its and EX), then it said I am at 569 at the flywheel. There is no way a stock turbo with hybrids can make that, that is like 512 at the wheels.

Did you notice this on the calculator page?

"These equations are for recreation only.

well yes but I've also heard that calculating using trap speeds and E/T's is a more accurate method than using a dyno...especially since there was a 50 hp difference between the last 3 runs I took on one.

Still, no way my truck made over 500 on stock turbo. Unless my truck weighs less than 7k that calculator is way off.
