If you're gonna bench race, at least start your brain.

Considering how much energy car people expend talking about horsepower and comparing how much they and their rivals have, there is a surprising amount of misunderstanding about how and where those horsepower numbers come from. While it's true that horsepower is horsepower, the circumstances under which it has been measured over the years has varied. To make a valid comparison, it's important to make sure you're using the same numbers for all cars.

Dyno Racing
We've focused on the F-body quite a bit because it makes for such an interesting case study, but this is not to say that General Motors has a monopoly on fiddling with horsepower numbers. "Tweaking" the numbers a bit is a common practice, especially in segments of the market where power sells, and amongst enthusiasts who have modified their cars but never put them to the test. At the end of the day, arguing about exact horsepower numbers leaves you with nothing but a day wasted arguing. You can't race a dyno; what matters is how fast a car can get down the track. If it can run the number, then the amount of horsepower it took to get it there, or how the horsepower was measured, won't change the outcome of the race. Next time someone tries to bench race with horsepower numbers, ask for a timeslip. If he can't deliver, then cut the conversation short and move on. He's not really in the game anyway.

thats a good one brenx, i have heard poeple discussing this before that looks it is proven, i was told it was 10% difference but either way there is a bit of difference between the two dyno's..
