A timeslip is much more credable than any Dyno, the dyno is only tuning tool.
400 meters is the test...time is a much more accurate measurment of a cars performance.
I have posted this once before it some up dyno numbers.
DYNO RACING.
"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.
