I would be down to test this, I have no doubt that TS and BG's dyno will read within 1% of each other. Both shops have confirmed this probably multiple times. I too have dyno'd cars from both Forged and Dyno4mance, this differenc was very little. IIRC the forged car dyno'd about 15hp more on my dyno and that was at 580hp so the percent is very little. Most of that could be a slight difference is boost or climate, and the DD was about 7% less. Thing is the more power a car makes on a load bearing dyno the less of a difference you will see. So at 500hp you may see a 3-5 percent difference, where as at 200hp it may be as much as 10-15 percent. Hardly what I would call accurate.

I think a perfect test would be to take a mid 400hp NA car and run it the same day on each dyno. I know that both BG's and TS dyno's would be accurate as we can't change our dyno to read higher or lower. But that can't be said for the other shops, both those dyno's allow the operator to make the manipulate the dyno settings allowing a 200hp car to make 300hp and vise versa.


Whats most important is you baseline your car and are able to show repeatable gains.
