E85 on bolt on mach

[BIGMACHDADDY]

I have searched this forum seeking an answer what I need besides a tune to run e85. I am confused because some say fuel pump and tune while others say 39# injectors and tune. So for a full bolt on mach except cams at the moment what do I need? Thanks in advance.

E85 you're going to need basically 30% more fuel to make the same power, + enough room for whatever increase the E85 might get you. I would think your tuner would be able to look at a log and see how much duty cycle you have left to make a recommendation

My gut instinct is probably not enough to be worth the expense and hassle but Ive been wrong before.

Agreed. Not worth it on such a mild, n/a setup. But if you're dead set, to feel comfortable id want atleast an e85 compatible fuel pump and lines in the tank. Maybe some 39lb injectors too. IIRC stock injectors max out around 350rwhp on gasoline. Not sure where a stock maf pegs but you'll probably be ok there.

Talk to your tuner!

Edit- your stock maf would definitely be ok. Just awoken brain fart, my apologies. Also, looks like a couple people have picked up around 15hp on bolt on cars from a quick search. If that's worth it, is up to you.

Ok thank you guys. I was just thinking if it was just a pump and/or injectors and atleast 5hp more i was thinking about it. But since it sounds like a hassle I will forget about it now until it's procharger time.

I'm going e85 just to see what I pick up. I'm going turbo down the road, but figured why not na? It's actually cheaper too, since premium is 319 a gallon and e85 is 179.

I plan on procharger down the line maybe even built bottom end but was wondering what would it increase for me now. I am going to get a retune this spring so i will ask my tuner what he has to say about it.
