converting to e85 Need some questions answered Hi all,
So to start off i have a completely stock fuel system from injectors to fuel pump. My drive train from front to back in an Lq9, 241's, MS4, ported ls2 w/ 92mm tb, 4000-4500 stall, flt level 5 4l65e, and 3.73's. I ran this at the track with a manual and shifted at 6800 and my AFR stayed around 12-12.5, it never leaned out.
I would like to know what is all needed to convert over to e85. fuel pump, injectors, fuel lines, etc...
any help would be appreciated!!!!
Thanks

With E85 you're looking at about 30% more fuel needed. I'd imagine that your injectors must be maxed right now. I concur with the 60lb. I use 42lb on e10 and get about 62% max idc. With E85 I'd probably be pushing 80-90%. I also don't have enough pump for it. The 340 would be a good choice. lol just go with everything IMPRTKILLER said. :-p

Why would he run an 8an feed? Doesnt that pump have a 3/8" outlet? So even if u ran the 8an feed the small 3/8" outlet on the pump would still be the restriction... Or is my thought process completely wrong?

Actually the pump outlet is approx 1/4" diameter with a check valve in it.
The flow capacity is limited by the sum of the total restrictions. The pump outlet can be considered a restriction, but I can assure you that 15ft of 3/8" line poses much more restriction than the 1" length of pump outlet. Every restriction is a slight pressure drop, but is not the limiting factor to total flow.
