Just say a 400 hp on the engine dyno. I know a lot of things can have different out comes. Say Auto car with turbo 350 maybe 3500 stall.

usally 20% loss through drive train, convertor has a big piece of it, don't look at ET, mph doesn't lie

Plan on a 100HP loss

We are real close to 20% from the rear wheel dyno #'s to the actual HP# on the time slips, this is at 525 to the rear wheels, never dyno'd the flywheel HP FWIW. But yea the convertor plays a big part of ET time on slips.
