Default E85

What flow rate would be most desireable if I were to run on e85. My current set up is for forced induction however money isn't entirely there so I will be running about a 150 shot of boost in the mean time I have some resurfaced 317 heads with ls6 intake and a 224/228 cam. I was planning on getting 44lb injectors however I don't think that will provide sufficient flow if I were to run on E85. Also what size fuel pump would be recommended and would I need any other mods for E85

60# injectors are good for about 750hp if you crank up the fuel pressure. I ran out of fuel pump with a single walbro at 430hp. Dual walbro or an aeromotive a1000 are good for about 800 or so. I run a fuelab 41402 and it is good for about 1100 on e85 with a -10 line and 83# injectors.

Well I'm just looking at having about 420hp. Plus a 150 shot so about 570. 600hp tops. So maybe dual walbro 255's

doesnt matter, the 79# idle just as good as the 42s and 50s and 65s so theres no reason not to get them, plus you will likely need them eventually. plus they are cheap. No way I would go with anything less than the 65s on a NA E85 setup even. Dual walbros will be fine

My FAST 57# injectors are 89%DC on E85 at 570rwhp NA. I am running stock LS3 fuel rails and a single Walbro 450lph E85 pump. I am probably going to step the injectors up a little but to get a safer margine.
