Whp vs. Engine hp?

The formula would have to be weighted, so if you were doing individual mods you would have to increase the .17 (17%) to maybe .25 or .3


300whp would be around 351bhp using the 17% formula which sounds about right

350 * (1-.17) = 290whp

which sounds right (although i have no idea what a stock nismo whp is)

you end up with around 351 BHP (300*(1+.17))

if you did the same to a stock nismo Z

you end up with around 364 BHP (311*(1+.17))
