you will hear lots of things about chassis dyno's. They are not necessarily very accurate in predicting flywheel hp.

But it would be an approximation to use 15% loss if you are running a stright axle, and 18% if an IRS.

That said, you could bragg that you have a 370 horsepower engine (15%).

At any rate, that is a really stout engine. That is substantially more than new Corvettes put out "where the rubber meets the road." I am sure it feels like it, too.
