man hobbyman you are frustrating. first of all the link says "clubrsx", so where do you get rx8. second, the power drops off at the end because the car has redlined. third, these are dyno runs, not flash runs. whp means power rated at the wheels, not the crank. the show your talking about is probably doing crank horsepower. fact is, its well known that certain cars take to intakes very well. like i said, you dont make 10whp(12 hp to the crank) all the way across the power band but maybe for 5-800rpms. the 11whp gain i showed you would have been at the "peak" gain. there are other cars dyno's i could show you to prove my point, like bullseye said with the cobra and the old b series hondas that got up to 13whp from intakes, but i get tired of arguing with people who dont show me anything empirical as i have done.
