Jeb: his 'placard' pictured on one of his posts read : "engine dyno testing yielded 516 hp at 6500 rpm on premium pump gas". seems to me that your question was answered in his prior posts. what am i missing ? so he says '500 to the rear wheels', guess he should have said '516 hp to the rear wheels ', but it makes no significent difference. oon any given day the same engine might dyno at different numbers, more so on a chassis dyno which is not typically in a controlled environment vs engine dyno that is usually more controlled.

utilizing more commonly used parasitic loss figures of 15 or 17 % vs 19% then rear wheel hp on a chassis dyno should come in at 415 or 425 respectively using 500 hp engine dyno stats...or 428 and 439 using 516 engine hp.

seems we are jumping on his numbers when we have not all read his other post that gave the answer ?? bill
