Default standard drivetrain loss?

Whats the standard % of drivetrain loss for a naturally aspirated LS1 with standard bolt-ons?

If I'm putting 350 to the wheels, whats the approximate horsepower at the flywheel?

thanks in advance,

Tyler

"about" 15 percent if 6spd 350 x 15 =402 @ fw
( I suppose as you are a short stick)
" about" 18 per if a4 350 x 18 = 413 @ fw
numbers are approximate

don't forget to tell him to add that back to his rwhp or divide rwhp by .15 or .18 to calc. fwhp. NIce avatar I like how it changes pictures.

figure 18% for auto ... and if you say "I calculated my flywheel horsepower to be xyz" near anyone that knows anything about cars prepare to be the butt of many jokes

(unless you pull your engine, engine dyno it, then dyno through the trans and rear... it's just a guess)
