Making your own E85?

[Vicious95Z28]

So how are you guys plumbing the twin pumps? Seems like even with twin 255's the line size would need to be increased to take advantage of the additional volume. Is there an aftermarket twin pump module for down in the tank or are you guys putting a sump in the bottom of the tank and running inline pumps?
If I supercharge the engine I'd like to use an F1 and shoot for the 700rwhp mark. What are you guys thinking?

How do u guys figure? How am i going to know what i need? Thats what i want to know... how do i figure out what pump i need, what size injectors ect.

Assuming 700whp, 55psi of rail pressure, you need 80# sticks. IMO twin 255 won't get you that level of pressure and flow. That is with 80% DC which you can vary as you see safe.

Stock hardlines and dual in tank 255lph with 80# stick on LT1 fuel pressure (40psi base, 1:1 rise) seems to only support mid 600whp on a MD.

More assumptions, but 800hp, .84 BSFC for E85 means a 672lb/hr

Dual 320lph pumps in tank. 8an feed/return and 80# sticks.

Shownomercy, what are are you guys doing to modify the fuel module for the twin pumps and the -8 line?

[shownomercy]

Beats me, I have a external pump and sumped tank.

Its not much work though, there are a few "write ups" if you say out there.

Thanks guys for all of the input on this thread, it's becoming quite interesting and informative. Would somebody mind teaching the math on figuring out how much fuel, injector, line size etc is needed for any given hp goal?

Google around, there are a couple good sites.

Download that excel and putz around, ton of info

Also want to ask how you guys are adapting the larger lines to the fuel rails? Are you modding the rails with an fittings?
