horse power calculators
 

Does anyone know if they are even the least bit accurate because I've gone through alot of them using my drag times and the estimates I get are 133 to 136 rwhp and 160 to 170 at the fly wheel.

I know that this is hella slow but it came with a stock 150 at the flywheel so there is some improvement.

here you go man, i had a thread about it but i guess sum peeps just ignored it, lol, its kind of accuate but not really but best bet is to get on a dyno

They give you a ball park number, but the times and weight of the vehicle need to be correct to even get a close number.
