This is a good point - the mid-range difference is due to ring and pinion change.
My 438 mustang run was a 4th gear 3.37 r&P (turbo box) - The 472 mustang run is with the S2 3.89 R&P. That is quite a bit less load for spoolup.
Also - The 951 at 400 RWHP level loses 30 RWTQ from 4th gear to 3rd gear. The HP stays the same.

Another issue that affects the run is the RPM at which the dyno pulls started. I would rather see the run starting at 2400rpm in order to load the engine/turbo.
I wonder what numbers we get running on a DynoJet??? Some claim no difference, some claim a 9-13% difference. I never done a back to back to comment on it.
I think a cam to match the head will bump it up some, then we'll look at the intake manifold

Blitz - I will. I have the S2 box, so it doesn't take too long at high boost. 
I can only go about 155 right now, but she gets up there pretty good.
Stock throttle body, yes.

Jim, at those boost numbers how do you know you`re not getting knocking? Any type of knock sensor other than the OEM sensor? EGT? Listening for knock? Or is the vitesse timing map good enought, and it all depends on AF?
