Wasn't the whole point to reach 750?
If it can "easily" hit 900 wheel why not just take the extra step

I'm around 750whp at 35PSI on my remnant kit DI only, Nostrum injectors, Fx400X HPFP, PR Stage 2.5 LPFP. IJDC is 76% at redline. 900whp seems like a stretch. definitely not "easy"

basic math says the injectors will support 986whp in your case, though youll probably run out of lpfp before then (not that 100% duty cycle is good, or anything, but...)

I know in theory it's possible if the relationship is linear, but i'm running E40. Higher e content would be required for more boost and as that goes up, so does volume, so it's not linear.

Volumetrically, E70 would maybe just touch 900whp as it maxes out the fuel system, and like you said LPFP wouldn't make it there imo.

E85 would tap out around 850 whp. E60 might not be enough to run the boost levels required to pass 900.

So anyways, not easy. Perhaps with a fuel cam and more capable LPFP.

I'm no expert so maybe i'm way off here
