Please take your riceboy math elsewhere.

 

You can't figure out quarter mile times and horsepower from just weight.

I have seen calculators like this but you need one designed for your car. I have seen them for Chevy and Ford but nothing less. The Ford calculator has gotten each of my Mustangs I had right on the money. Even down to the MPH. This math calculator just sucks. Nice try though.

 

Woohoo! My 3200lb C5 Coupe makes right at 400hp based on my best trap speed of 117.3mph. Gotta love an LS1's ability to pick up 50 flywheel horsepower from intake, headers, and exhaust.
