This chart was just made by us today. Engine dyno of our 6.54L motor. Shows 900 HP at the crank (OK, 897.7 ) She was running real smooth, too.

I will post the video just as soon as I can.

We use only gas and boost. No other additives. Gas was Sunnoco 110.

Peak manifold pressure was 186 Kpa, Boost pressure would be 12.3 psi.

The blue engine in my car has almost all stock or lightly modified stock components. Stock valve sizes with minor porting. Stock pistons with dish machined into them. Stock crankshaft with done oiling improvements. Stock ppf rods. Stock intake manifold with some porting. Modified S3 cams with new profiles. Stock throttle body element. Stock 5L displacement. Stock computers with ST2 software. So the two engines are quite different in terms of what they are and what design philosophy they are based on.
