I believe dyno numbers are a solid component to tuning your engine to get the maximum horsepower, but comparing your dyno numbers with others is seldom a good method for comparing horsepower unless done on the same machine.
With honest calibration and operation, dyno numbers can be very close, but we often find shops selling horsepower on "loose" dynos....or even worse, selling horsepower they have not even tested on a dyno.
Several years ago, I ran the same engine on two different dynos in two different shops on the same day and ended up with a 10% horsepower difference. Which one was correct or were they both wrong?
I often sort horsepower numbers out with elapsed times, but these can be misleading as well, mainly due to tires, limited traction and gearing of the Cobra.
But for sure, these 600+ flywheel horsepower rockets turning quarter mile times in the mid eleven to twelve second range make me wonder
Not trying to run anybody down, just sayin' ..........
