It's due to a difference in the loading, just as a street pull for a given rpm range in 1st gear differs from the same range in 4th. As one applies the air drag and such of a real world, high-speed track pull to a static mass dyno roller (Dynojet), the difference becomes significant.

dave, how do you like the 35hta compared to the 67p trim?? depending on next years rule book im wondering if i should give up the 67p for the HTA maybe.. i was told by a friend of ours that the 35r will 1/8th mile quicker and faster probably.. if the 35r can make 700whp it may be better all around..

David, I know this is absolutely an idiots question to ask, as its almost obvious the answer....
HOWEVER....what type of fuel, specifically are you using? Brand/Octane etc....and methanol injection, yes, no? How much, and jet sizes?
Just curious, is all.
Keep up the amazing work......its astounding.

i just dont understand why the ~10% difference in fueling due to the dyno if both runs were conducted in the same gear......that would require a huge ambient condition change between the 2 runs....
besides, i would have expected a higher dj whp number to boot, if db's car made 661 on his dyno to the 70? on the dj

AFAIK, Dynojets cannot be 'recalibrated' to read differently. The loading however is less on a Dynojet than it typically is with an eddy current dyno, and this can affect the disparity in the numbers.
Good numbers for a 35R, but I have a simple question: If the compressor wheel and housing are different (don't know particulars about the turbine side), just how much of this turbo is actually "35R"? It seems to me that it's about as much a "35R" as an FP Green is a "16G". . . ?
Lastly, the big torque figure is a product of reaching max boost pressure fairly early in the rpm range, coupled with things like stock-sized intake manifold, cam characteristics, etc.

FP-Green is a 20g isn't it? anyways . . .
Nice numbers david and congrats. i'm definetly lookin into gettin this turbo!

I know DB uses VP import and does not use Meth.
The disparity in the Mustang and Dynojet is confusing and the answer must be that it was somehow rich and not completely retuned to achieve maximum HP, otherwise the difference is only 5.5% between the Mustang and the Dynojet.
Just tryin to clear things up DB, please correct me if I am wrong. Great #'s and I am a huge supporter of the Buschur race ethic!!
