I guess the easiest way if you wanted to do about a 15-17% drivetrain loss, just divide the WHP by .83-.85

the drivetrain % isnt a static ratio. as you turn up the power, the % will get lower. 15-17% is extreme considering his car just laid down over 510rwhp... but i guess it doesnt even get that crazy so whatever. i would figure your engine is making around 585 - 600 HP. So I guess it does kinda work here.
