1999 SS

iTrader: (3)

is there anything that i need to replace (fuel lines etc.) to run e85 in my 1999 SS?

i already have a walbro in tank and plan on going with 60 lb injectors but will i need a boost-a-pump or bigger fuel lines too? will 60 lb injectors be big enough for 600rwhp?

the car has NW 90mm tb, fast 90mm intake, 85mm maf, f14 cam, ewp, qtp long tubes, no cats, 4" exhaust, ported heads and so the P1SC im bolting to it will probably be maxed out and am thinking e85 would be a good way to safely get a few more horse power out of the stock CI motor. plus they sell e85 at almost every gas station around here.

Unless you're going for more than 16psi or so I wouldn't recommend e85. At 16psi on your motor you should be making 600rwhp on 93 gas. To use e85 you would need at least 2 intank walbros, boost referenced regulator, and 83+lb injectors. All that and you'd be burning double the fuel while in boost vs gasoline. If you were strapping an F1c+ to your forged 346 it might be worth it but not at your goals.

FYI, at 625rwhp on 83lb injectors I am at 85-90% IDC running 58lb base fuel pressure, 3/8th lines, and twin 255s.

E85 is the shiznit! Just takes a lot of it to make big power.

i was reading up on using it also but they don't sell it anywhere near me. but your fuel system needs to be able to flow 20% more to run E85.

More like 40-50% more to be safe and give you some headroom.

You will need the equivalent system for 800rwhp on gasoline if you have 600rwhp on E85.

You will need additional pumping capacity, line modifications & preferrably 80# or larger injectors.... 60's are marginal & you will likely exceed your power rating once you start modifying things, making the 60's too small.

Feel free to contact me if I can help.
I have pumps, lines & injectors in stock to get you a properly designed system.

80s will get you to 750rwhp with -10 feed and a good pump, with 75psi base pressure.

I wanna run e85 also. So far I have a A1000 pump, 60lb injectors, sumped aluminum tank, -10 feed, -8 return, still need to buy a regulator and motor is a stock 6.0 with a blower cam with a d1sc at 10-12 lbs of boost. I have a ton of e85 pumps so that's not a issue. Still on the fence about it though. Any input? I wanna get my max outta my combo so figure e85 would net me a few more hp

I am swapping out the current A1000 and picked up a huge Fuelabs unit to handle the E85 volume needed to feed the new hi-boost 421ci/YSi combo. Still researching whether I must upgrade my Earl's Perform-A-Flex braided SS lines or not. Went to 120# injectors, again to have some headroom, starting at 43psi.

I would go E85 in a instant if there were more stations here. There is one down the street but none on the west side. Im gauging how long this station keeps it available. Never see anyone using it. The issue of more effort needing to be placed on the fuel system is a non issue for me at this point in the game.

will i see any worthwhile gains on the set up i mentioned when going with e85 or is it mostly an option for guys over 600whp?

im in the same boat as you(looking to make 600whp stock block on e85,but spray) and have been told a few things. one person said to do feed, return, twin pumps and upgrade the rails. the other said twin 255's make sure i have enough injector and call it a day.

on e85 for two years now.
my latest set up is 600rwhp/600rwtq with twin walbros and 60lb injectors which are at 95 and up DC. I'll be getting 83s soon, idle was hard enough on the 60s, not looking forward to working 83s to idle.
i keep tweaking my tune and getting 22mpg vs 26mpg on 93. not a bad trade off.
also, e85 is very forgiving vs 93octane. got lean when learning how to work the tune, 14afr on boost and did not blow the motor, few others in my part of town have experienced the same thing, which would have sent our ringlands to heaven on regular gas.
the only downfall i see is if you don't have it in your neighborhood.

i have two e85 stations within 3 miles of me.

question is, will one a1000 pump support 650rwhp on e85?

Built motor or not? The fuel has lots of positives but the negative is that you will need to add another pump and a larger set of injectors at a minimum. You will be able to make more power on e85 and have a larger safety margin (in case of failure)in comparison to pump fuel.

stock short block with ARP rod bolts. i know im on borrowed time but if i blow it that gives me a reason to go bigger.

will the oem ecu run 83lb injectors?

i already have a walbro intank can i get away with a boost-a-pump, or inline fuel pump or will i have to do dual in tank pumps? if i do the dual in tank pumps will i have to increase fuel line size too?

is there any benefit to running a meth kit if im also using e85?
