We've all heard "You can't compare data from one dyno to another, blah, blah, blah." In that same realm, I was chastised for comparing our FP Black Turbo results on Cobb's Mustang Dyno to our HTA86 results on another Mustang Dyno. We'll, lets take a close look at how close the Cobb Mustang Dyno REALLY is vs another Mustang Dyno and a PT6262 turbo. It won't take any imagination, just an intelligent review of the numbers and the results.
Known: Our car made 656 whp on Cobbs Mustang Dyno at 36 psi.
Known: XXX made 658 whp on their Mustang Dyno at 36-37 psi.
We used the FP BLack turbo, they used the PT-6262.
Both cars are very close in weight, probably within 30-50 lbs, based on quoted figures by XXX. We weighed just under 2700 lbs BEFORE adding a full cage, back seats, stock moustache bar, chute, chute mount, cables for power shutoff, window net, misc extra boost control items. We figure we weigh 2850 with driver now. The XXX car has all the same items, but has no back seat, DRY carbonfiber deck and hood and not sure about the moustache bar. They said it weighs 2885 with driver. The driver weighs 200 lbs, so that puts their car at 2685, we're at close to 2720. The XXX car is probably lighter, but we have a lighter driver (Thanks Tony). That's 35 lbs of total weight difference.
At this point, it should be said that the XXX car is possibly one of the cleanest, nicest builds on ANY race car. This is not about their car, nor our car. This is to show that you CAN compare data between dynos and be ACCURATE about it. Now, back to the comparison.
Specifically, I was called out about comparing different turbos, dyno'd on different days at different shops. Here we go: These two cars are nearly identical in weight. They both made within a couple of horsepower on Mustang Dynos, on different turbos, on different days.
The results don't lie.
We were told that there was no way that the Black made as much power as we had posted. We posted 686 whp @ 40.6 psi. We also posted that it made 656 @ 36 psi. NO WAY. Ha, ha, right!! At the SAME 36-37 psi on the PT 6262, XXX recorded 656 Mustang Dyno WHP and nothing was questioned. The results of that dyno run and tune? ET of 9.75 @ 150.00 mph. We also made 656 whp at 36 psi and recorded an ET of 9.53 @ 148.43 and 149.58 mph. Both cars were run by both drivers getting used to the new setup. Very similar setups, nearly identical results. Now, still think the Cobb Mustang Dyno reads ridiculously high. If it does, so do a lot of other dynos. By the way, there's a big difference between 10.14 @ 136 and 9.53 @ 149 mph. That difference is only made up with big differences in horsepower. There IS a weight difference, but not THAT MUCH. Next time someone says you can't compare...blah, blah, blah. We always said that the numbers were much closer than people realized. Now, the results speak for themselves. By the way, both cars had decent 60's. 1.53 for XXX, 1.56 for us. The power of the FP Black was real, just too much nutswinging for readers to get through the BS.
End result: The Cobb Mustang Dyno is dead on when comparing whp and results vs other Mustang Dyno's. The facts are the facts. It doesn't look like 'ridiculously high dynojet numbers any more, now does it.' Just another ridiculous statement from a slanted viewpoint.

Good numbers regardless.

Thanks, nice thing about track numbers is they don't lie. Nice 60ft times BTW. I knew I'd get this comment about high reading dyno even though my set up yeilds about 400whp even on most Mustang Dynos. It doesn't bother me here I exepect it from a large Portion of this community.

BTW - great numbers. I hope to be right behind you and get a Green and Kelford Stage 1 cams soon. Did you need to upgrade your fuel pump? How is the idle on the cams?
