ADM performance recently made 680whp with a SS 1LE using the LT4 1.7 supercharger @ 9psi, LT4 injectors, and LPE big bore pump on E85. The big bore gave them another 60whp of fuel headroom over the LT4. They were capped at 620whp prior.
I am debating weather or not I want to tap the tank for SMG auxillary or just run a ZL1 with BAP or both. The SMG setup is good for 930whp on E85 according to the guys over there. Also much easier to install.

Makes sense.
I was told the cam should be considered part of the fuel system upgrade, but that will allow me to safely run 750whp.
I am surprised the fuel pump could make that much of a difference because if I see the numbers correctly on my setup we will run out of injector time before the in tank pump is out of room (running e at 750whp or race fuel north of 800whp). When does the HPFP run out of capacity? Based on ADM results, I assume the hpfp outlasts the low side. What about injectors? Like I said, I thought we would see them cap out before the lpfp...
Btw - no argument from me, just trying to understand because there seems to be so much conflicting information out there, I love to understand what is real.
