717 rwhp @ 6200 rpm 813 rwtq 5000 rpm at 19 psi. The turbine housing a/r is too small .96 and would not let the motor make power past 6200 rpms. We have a 1.15 a/r housing on order that should make 50-100 more hp. An 88mm T6 combo would make more all out power but the responce is unreal with this combo.
It makes 70 more hp, 200 more tq. It is a beast compared to the nitrous motor.
My understanding is that our heads are the same.
Douglas has the first EFI turbo setup.http://www.youtube.com/watch?v=baj4UmT02RM
