I will eventually build a fuel system to support the all mighty corn liquor. Please let us wanna be e85 folk what it takes. I am thinking Two walbro e85 400's , -8 , aftermarket rails, 103lb injectors, aftermarket regulator, stock feed as return. Feel free to tell me where I am right or wrong.

Would love to hear how people already running it made it happen.

THANKS

i'd also like to know what people are doing with there e85 setup's. more so what injectors people are using in 700-800 rwhp setups. I'm thinking the FIC1000's will do justice?

20 gallon cell with two -8 outlets into two Bosch 044s with a -8 outlet on each then Y'd into a single -8 up to the rails and Y'd again in to two -8s going into the back of each rail then out the front into a aeromotive 13101 regulator with a single -8 return to the cell and 120lb @ 43.5psi injectors. Persevere seems to be holding steady but injectors are maxed out and I'm running a 75psi base pressre

Thanks for sharing! time for 160's ??? on a 5.3


What intake are you running? dare I ask for a pic?

are those 120s low or high impedence?

Slowec, got your PM, but I'll post up here for the benefit of anyone else looking at going corn-fed.

I am a stock 5.3 flex fuel, so it has a fuel sensor detecting the mix of gasoline to E85 and Wheatley set up the high octane tables to adjust based on those sensors. I don't think HP Tuners lets you adjust the E85 tables yet, but I believe EFI Live does. But there is a night and day SOTP difference between 93 and E85 now, probably 40-50rwhp according to my butt dyno. Also, by law I believe that E85 has to be minimum 70% ethanol (not necessarily 85%), so be careful with tuning as the Kroger I use Wheatley read at about 72% ethanol.

My fuel setup is pretty basic. I have a return-style system with the stock flex fuel pump (that flows about 260gph according to Jon at FIC), boosted by a 20A Kenne Bell Boost-a-Pump triggered at 3psi. The injectors are Ford Racing Ford GT OEM injectors (part # M-9593-G302, EV14 body style, USCAR connector, 47lb at 39.15 psi, 6-hole, high-impedance) opened up by Jon at FIC to flow 75# at flex fuel pressure, 47 psi IIRC, and spray pattern narrowed for a 2V engine vs 4V to reduce wall-wetting. They were drop in with no spacers for my truck, but I do not know if the NNBS FF injectors are the same.

This is going from memory when Wheatley tuned it for E85 a while back, but I believe WOT timing was in the high 20's and cruise was around 42-44*. My mpg did drop from 11.5-12 in the city to around 9, even with the added timing at cruise. He spent a while trying to milk it for all the mpg it was worth, but that's all it had. I am still on the MAF so he can't command lean cruise, but OLSD might have some better results. In Houston, E85 costs about 20% less but mpg is about 30% worse, so it still costs more to run E85 overall. Congress also let the $0.45 ethanol subsidy expire, so that has brought the price of E85 up.

i got 2 walbro 255's that y off into a -8 line into ls1 billet rails into a aeromotive regulator with a -6 return . running 80# SIEMENS DEKA that are maxed out but thankfully for the regulator it is allowing me to press on with it being 1:1 . i need to get some id2000 injectors and be done with it, im so tired of upgrading injectors at this point lol this is my 4th set of injectors . i dont know what power im at 6-700 range ?? but im running 16#'s on e85 . so if your going to go the e85 with big power route plan for the biggest you can buy with the fuel system 100+ # or cut to the chase and get id2000 injectors and 2 044 pumps would be the way i would do it if i had to do it again.

Yup, gona try to get some 160s soon. Yup, stok 5.3 with a baby cam. Pro flo intake. High impedance. There the bosh racing 127s from FIC. I'll post a pic when I get to a computer. Or look on my face book, there's a few

what injector driver box you running?
