We wrapped up the dyno session. It starts clean, idles smooth, and spools almost instantly. It's a BEAST!
1600 hp @ 6000 RPM
1430 ft/lbs @ 4800 RPM
only 22 psi 
This was on a very conservative tuneup and shutting the pulls off early at 6000 RPM just to be safe. To give an idea of the full potential, the engine is set up to run in the 35 psi range. This thing flows a TON of air - we didn't even make it breathe hard. After a crap load of development pulls we just decided not to beat on it any more - went though 45 gallons of C16.
It starts pulling off 1000 ft/lbs at just under 3700 RPMS.
It made 930 hp with a measley 7 psi boost on pump gas and 13 psi put it at 1207 hp.
The turbos are the limiting factor here - not the engine. Even at this level it'll have plenty of power to drive it to the track with the AC blasting, bust off some 7 sec passes and drive it back home. Anyone can hang a tag on a race car and call it streetable - this should be the real deal. A switch to a pair of T4 flanged 88mm turbos should pick it up an easy 500 hp putting it over the 2k hp mark but in it's current trim it should be very streetable which is the primary goal - for now.
Love 'em or hate 'em, these LS motors are simply awesome. :biggrin:
