So I've had my build specs figured out for a while, and I'd like to hit 450hp at the wheels. If it turns out to be more so much the better, but I've never really asked those that have done it already if I am on the right track to make that power. So...

94mm stroker
CNC ported evo head with +1 valves
GSC S1 cams (want to retain some street manners)
8.5:1 comp
evo 3 intake, 'power ported' for even flow
1250cc injectors
ported evo 3 exhaust manifold
ported 9 blade turbine td05-20g @30 psi on E85, and however much I can run without ping on 98.
3" dump/o2 off turbo
Ralliart copy 3" mandrel exhaust
ECU: ecmlink running speed density and flex fuel sensor

I've kept specs list short. You can assume I have other engine specs and supporting mods sorted.
 
have a look at the 20g compressor map.
looks like your 30psi at 450hp is outside it's operating range.
 
That had crossed my mind. Seeing as I have the 20g already, I am planning on seeing how far I can get with it and if necessary swap to a FP green.
 
1250cc injectors may not be enough or they'll run at their max duty cycles depending on your base fuel pressure.
