Default how much power loss to drivetrain?

Just wondering how much power you would loose to the wheels through the drivetrain of a 98 mustang gt rated at 215hp? i used a hp calculater that takes your 1/4 time and your trap speed and it tells you how much hp you make to the wheels, it says my car has 210.9 hp

general rule of thumb:

15% loss for a manual
20% loss for an auto

your looking at about 185 rwhp if its stick or about 175 if auto. Yea these GT's dont make a lot of power. Thats why most on here will tell you to do a pi swap in order to get about 40 whp.
