Well call it what you want, take a motor and crank dyno it, then place it in a vehicle and add a water pump, power steering pump, and a alt. Then on top of that add a auto tranny with a loose non-lockup converter, spin a rear end assembly, brakes and a set of tires, then suck some nice warm underhood air into the motor ( even with hood open the vehicle is sitting still ) and see how much power is lost on a wheel dyno.

If anyone on here has crank dynoed thier motor and then placed it in thier truck and wheel dynoed it post up your numbers.

How much power do you think a drivetrain and accesories eats up? Also how much power do you think his combo should make at the crank?

My ballpark guess would be (with what he's using right now) is 425hp at the crank, that about a 125hp loss with his drivetrain and accesories. I wouldn't bet any body parts on it but I would bet $20 I'm close.
