As others have already pointed out, on average, you can expect a 18-22% loss between flywheel HP ratings and HP ratings at the rear wheels. You can get those numbers down below 15% if you are willing to do a lot of extra work to your driveline. Headers/exhaust/tune......Everything from the types of fluids in your motor, transmission, and rear end to which bearings you have, how tight the tolerances are in your transmission/rear end just to name a few. I've watched some of the circle track guys spend days on chassis dyno's to wring out that extra 5-12hp as an advantage over their competition......
