Online Horsepower Calculators

fly wheel hp....ok

How does..the calculator know if I am running a 904 or 727?....a 727 takes more HP to turn then a 904.....

I can run almost 2 tenth faster with the 904 which shows more hp....but the engine is making the same hp with either trans...

I would assume the calculator uses a flat % of drivetrain loss regardless,,,,

dynos and calculator should be taken with a grain of salt..
