Have verified with the owner of 5252 that the dyno dynamics is corrected to read exactly as dynojet. The showing of Flywheel HP is how his software is set. The reading is WHP.
I won't belabor the same point others are making about flywheel vs. wheel horsepower.

But I will comment about Dynojet vs. Dyno Dynamics. The difference is usually about 11%. You can see in the upper right there is a field that says "Extra corr: 1.000" -- that means there is no extra correction being applied. That makes sense because in flywheel mode, you wouldn't want any extra correction applied.

Another thing that caught my eye was the dyno correction factor. They are using J1995 instead of J1349 correction. That's a bit odd...but doesn't mean anything other than that. J1349 is the standard most people use. So let me translate that for you and give you the numbers in all the various correction factors.

Car-1:
Unc: 643.6 hp, 437.9 tq (uncorrected)
SAE: 628.5 hp, 427.6 tq (SAE-J1349)
STD: 645.5 hp, 439.2 tq (STD/STP)
J1995: 632.0 hp, 430.0 tq

Car-2:
Unc: 628.6 hp, 426.1 tq (uncorrected)
SAE: 613.4 hp, 415.8 tq (SAE-J1349)
STD: 630.1 hp, 427.1 tq (STD/STP)
J1995: 616.7 hp, 418.0 tq
