Midwest and lots of 85 stations where im at

Looking for 20# or more and need to know

 

depends how big your fuel system is and what power you are shooting for

 

If you have E85 readily available, i see no reason not to use it. Youll need dual pumps and some big injectors fuel wise but its worth it.

 

Twin pumps and 80#

 

Youll max out dual 255s around 800whp on an ls1. The 80s will be done near mid 700 but the injectors depend more on your base pressure.

FWIW i made the numbers in my sig and my 80s were in the upper 90% duty cycle range on E85. Im putting in 127s soon, they should be good to 1000whp with a ~58psi base

 

What pumps?

If you want to know exactly what any setup will do, read this and use the spreadsheet attached to the post: http://www.performancetrucks.net/for...4/#post5024253

 

What psi u running now with your sig setup?

 

like they said if its available there's no reason not to run E85 buy a good pump & some 120s

 

Id go e85 over meth if its readily available. It will eliminate an additional failure point from the equation. Im stuck with meth because the closest e85 station is 60 miles away. Even that distance though im really debating getting a drum to store at the house though.

 

Drumming it would work but I burn up 55 gal on fri and sat night alone haha.

 

closest place to me is about 15 miles I have several 5 gallon jugs I go fill up at once.

 

Boost wise, i turned it up to 15psi about a month before i put it away for winter. Didn't skip a beat. Most of the summer i was around 13-14psi. Base fuel pressure has always been 58psi with a 1:1 rising regulator.

 

80's will support 850rwhp on e85 without an issue, we've done closer to 950rwhp before they maxed out on my mustang with lots of fuel pressure.

 

Damn, what was your base pressure? And what pump(s)?

 

U bump the line pressure above 70psi and u can make it happen. Even using the stock fuel rail and lines.

 

don't need twin pumps, do need a high flow system, we run a pro efi magnafuel, 25lbs, E85, over 1000hp..

 

75 base, 24.5lbs boost so just shy of 100psi in boost.

We've done the 850rwhp on stock rails fine and stock lines, just need a good regulator up front.

 

Hey skins. Who tunes your guys cars? ?

 

I tune my own, maxxmitchell does all our customers cars.

 

I knew the stock rail and lines were good to 800+ but thats the first time ive heard of 80s going that far. good info. I gotta find me some better pumps!
