If my car has 250 hp, about how much would actually make it to the ground? From what I hear, about 15% is lost in the drivetrain.

What I do is subtract 30-40% from what each mod is "expected" to add.

It'* usually 15% loss in a manual tranny car and 18-20% in an auto. With 250 HP your probably putting about 200 HP to the ground.
