Can you make 1000hp at the crank with a D-1SC

I have a D-1SC with a 15lbs pulley. The motor made 781 @ the crank. Is it possible to pulley another 220 hp out of the motor. DART 406 with

Unfortunately, probably not. You'd have to overspin the crap out of the blower, and you'd probably be way out of the D1SCs effiency range. An F1, F1C, or an F1R would all bolt into the same bracket though.
