Anyone know how big of injectors and how much fuel pump would be necessary to support about 900rwhp on E85. I will not be hitting that this year at all, shotting for closer to 6 since ive got a relatively stock shortblock, but next year when I step it up, I dont want to have to buy injectors again. Im thinking 2 walbros will suffice for this year, then add an extra next year. 100lb injectors?

Motron 60#'s there are some going strong in a 750 rwhp range at 60% duty cycle. Ask a few guys about their injector/fuel set ups that are running big hp with 60#'s. yeh shocked at that, I would normally hear numbers around 80%. but those are LS motors not LT. as far as using those and e85 I don't know but I was told that I have a station that sales it really close by.

I'd recommend 120# injectors and a 2000hp pump (magnafuel 4303). From my personal experience, you really have to "overbuild" the fuel systems to make it work. Basically double the fuel pump that you'd need on gasoline and 150% of the injector you'd need on gasoline.

Just put 160's in it and be done with it, that's what I did after buying 60's, then 83's. For a fuel pump, I've been running the Aeromotive eliminator with good results, but might move up to the pro series or a Weldon.
