750 rwhp with my fuel system?

[YGETV8]

I've been researching with little luck, and just need some more input if anybody has some please. I'm quickly running out of funds and am wondering if I can jump to E85 with my current fuel system with a couple small upgrades? Right now I have twin GT pumps, PPRV delete, BAP with upgraded wiring, modified FPDM, and 60# injectors. Would the fuel line upgrade from Lethal and a switch to 80#ers support 750 rwhp? I know Vadorsnake (Hi Blake!) has done over 800 with 80#ers, but he has a KILLER fuel system backing them up! Thanks for any help! -Jay

your twin GT pumps will be your limiting factor as well as those 60's. If you go to a triple setup or go to 3 walbro's and 80's you will be ok!

More pumps and his 80s were done with a return setup.

I'd think it will be SUPER close even if you do the line upgrade and switch to 80s.
skaarew04svt over on MF made 707 rwhp SAE on a Whipple 2.3 and his FPDC was around 92%.
His setup was:

Twin GT pumps
GT500 BAP
Dual Stock FPDMs
-8an feed line
80 lb injectors
Stock rails

What is your FPDC @ 750 rwhp on gas? Do you have current numbers you can compare to? And are you a turbo or blower car?

Combo will be all new so current numbers are irrellevant, unfortunately. I guess if I want to jump to E85 I better go big or go home!! Thanks for the input.

or drop in a couple of the new Auromotive pupms in place of the walbros and get some 80"s
