3.3 Turbo dyno results?!

Interestingly, the turbo cams are even milder than the SC cams, in an attempt to shift power in the turbo from high RPM (which is normally on-boost anyway) to low RPM (where boost may not have kicked in yet) in order to reduce the difference between on- and off-boost behavior.

Actually in addition to headers and a K27 the best other mod to improve low end performance on a 3.3 turbo is SC cams. With headers and a k27 the boost kicked in at about 2400 RPM, with the cam change boost comes at about 1800 RPM. These mods make the turbo very streetable. and without the binary boost characteristics of a stock 911 Turbo

The engine that made the massive power has among other things an intake (intercooler,individual throtle bodies w/ 2 injectors each) that cost $20000 just by itself! The engine uses EVO2 cams, and runs on 116 octane fuel. The heads were ported and smoothed. The headers are 1 7/8" SS. I believe the turbo is a modified K-29

The case was boat-tailed and shuffle pinned, the crank was crossdrilled. It has a GT3 oil pump.

The fuel system uses 2 in tank fuel pumps, and 2 paxton 1000hp fuel pumps. all the fuel lines are -8 braided.

720 was seen at 1.4 bar, but for longevity sake the engine is usually run at 1.2 bar. At 1.2 the engine makes in the mid 600hp range.

The motor isnt a 935 motor, but cost nearly as much as a 935 motor to build.

Untrue--fuel isn't a tuning component, but the needed ingredient for highly tuned motors to run properly. Ask the F1 engineers if getting big power from engines on racefuel is easy.....
