Good info guys, thank you all so much! I also failed to mention that I am running a dead head setup (regulator BEFORE the rails) so I don't think the -10 will cause the same heating issues that it may in a normal return setup. My last concern is the pumps, is twin 340 division X pumps enough to support 650 rwhp on e85 without a BAP? I do have the wiring upgrade from Lethal also so I am assuming this will be plenty, Lethal and a couple others told me that the twin 340s with 80# injectors will support me up to the 700 rwhp range which I may reach after nitrous. Ill be on a D1 with 2.8, 8 rib and 15% IW OD so my guess is somewhere in the neighborhood of 600 rwhp (through an auto) and I will also have a 75-100 shot just incase.
