compared to a Dynojet, due to ZERO losses of rolling mass ie wheels/tires rob rwhp wheel weight etc... It's a known fact that larger diameter wheels kill perf at the track so the dynapak is going to give false #'s

I always heard the Dynapack measures about 10% or higher HP compared to a Dynojet, due to ZERO losses of rolling mass ie wheels/tires rob rwhp wheel weight etc... It's a known fact that larger diameter wheels kill perf at the track so the dynapak is going to give false #'s

you can't really call them "false #'s", they're just different (as are all dynos). i would agree that a dynopack's results are going to be higher without the losses that occur between the wheels and the rollers on other dynos. it's the people insisting on being able to compare one dyno to another that's the problem.

Sorry - I am a bit lost. Are the gains on these "headers" being measured on a dyno that is different from the one on which the base measurement was taken? In other words, was the base done on a dynojet some time in the past and now being compared to those recorded on a Dynapack? That obviously doesn't work.

Same dyno ... just a hub mount version ...
Its the 34HP increase claim that has everyone a little surprised. If true I'll get these puppies.
