E85 and nitrous im about to make the switch to E85 from pump gas 91oct.
Im just wondering if my setup is gona have enough fuel pump on spray.
my setup is a LS2 cam only, NX 175shot, walbro 255 pump.
i wana stay with a 175shot-200shot on E85... will my pump do it or what will i need?
how much timing are people getting away with on spray compared to pump?

not sure on your fuel system setup
you can usually pull 1deg less timing per 100hp of nitrous, and keep in mind jetting is different for e85, feel free to call or pm me for e85 jetting if you need to

do you have a fuel pressure gauge?
i would either run a fuel pressure gauge or a fuel pressure safety switch (cheap insurance) that way if your pup isn't keeping up you will know before you hurt anything

100hp gas jet = .017
.017 x .017 = .000289
.000289 x 3.14 = .0009079
.0009079 X 1.3 = .0011802
.0011802 / 3.14159 = .0003756
Square root of .0003756 = .0193804 = radius of new jet
.0193804 x 2 = .0387608
New E85 jet size for 100 shot = .039
I'm just stating what happened with my buddies camaro. We got a new gas station in town with e85. He has the same setup (255 fuel pump w/hotwire kit and 42lb injectors) retune for e85 was fine, but on the bottle he maxed out. Take it for what it's worth. Worst case you switch back and wait until you save up for some fuel upgrades. And even though it's a wet kit, pulling fuel off the rail is still fuel not getting supplied to the injectors. Perfectly fine for smaller shots, but you won't find many people with your setup spraying nitrous on e85
