And I see peak boost a couple of hundreds RPM earlier than you do with a smaller engine ????
Flow, Altitude, and (likely) temperature. Flow wise I'm probably outflowing all but a handful of cars out there at this boost level (and boost is just a funticion of flow resistance). At my altitude the turbo is working just as hard at 33.8 psi as it would at 37.8 psi at sea level. And temperature wise Norway's not exactly know for it's warm weather.

Probably a combo of the conservative timing up top and the 62mm throttle body, stock intake manifold, and 1.01 AR turbine housing clogging things up.

I'll cut you some slack since it seems you two aren't familiar with Mustang dynos. You (or your smart friend) should do those calculations backwards using my 1728cc injectors at 83.66% IDC. Actually I'll save you the trouble; at 0.78 BSFC & 9.68 cc/min to lbs/hr conversion you'll find that is 1148 crank HP worth of E85. While Garrett likes to under rate their turbos I don't see a couple hundred more HP hiding in there.
BTW...can you post your dyno? I'd like to compare my car to another pegged out single.
Has the stock 6g72 knock sensor picked up anything on the E85? there is whisper that the knock sensor is not tuned for the frequency....you seem to be Mr Experiment at the moment soooo?
cliffs:
816awhp. 2l, E98, 45psi (tapering to 42), doesn't hit full boost until 6500ish, peak tq at 7kish (540 vs trevor's 760), revving to 10k. 1.7L makes quite a difference

Off topic:
That car is going through some work and should best its current fastest pass and the previous dyno results. (Best friends car and the one I was referencing on Trevor's other thread). It hit 829awhp/554tq at around 40psi on a local dyno jet last time I was messing with it (last fall). Car was breaking up due to a new head and other changes on the setup that weren't ironed out.
On topic:
What is amazing is to see the extra displacement and how it shifts the torque curve to the left on Trevor's setup. The GVR4 is a drag car and doesn't drop below torque output once its off the line, Trevor's car is ONE HELL OF A STREET CAR as well as a monster at the track.
