i cant make up my mind as to if i should go with E85 or just stick with 93

setup
8.5cr
b18c stock block and head
je pistons
eagle rods + crank
walbro 255
precision 1000c
gt3076r with ram horn manifold and 3" all the way back

will i have any trouble with maxing out the fuel system be4 i see any gains from E85? i still have stock lines, rail and reg

any info would be welcome this idea just popped in my head after listening to a guy at work wanting to run E85 in his MR2.

and im i correct in the understanding that tuning the a/f for E85 you would shoot for the same a/f as gas because its just reading lambda then multiplying it by a set number(depending on type of fuel) to display a a/f ratio

 

you will have enough fuel to handle 400hp. Alll in all it costs about the same to run as reg 93 oct. but the advantage to me comes with the increased torque. and the fact that i run full boost dailly!

 

For what its worth, my friend made 595/420tq w/ 2.0L LS/V ITR cams on a dynapack and traps mid high 10's @ 140-143 in a Hatch running a single 255hp and 1000cc Injectors w/ stock lines and E85, car weight in the 2400lb w/ driver area.

I have made 585/385 stock bore/stroke and GSR cams on a dynapack with 2 255hp's, 1000cc's and -8 feed and went almost 130mph in the 450/475hp area and 2700+lb with driver.

I know a dynapack is not 100whp over what a d-jet reads, so I am going to say from my personal experiences, 500whp on E85 is doable with 1000's and a 255hp.

I tell everyone that can run E85 to do so, I was running around the streets with damn near 600whp on drag radials running bikes and holding my own with a fuel that costs less than $3 a gallon Not to mention the corn just seems to make my car run smoother and act much more responsive all around.

 

sounds good to me and it wouldnt be hard for me to run duel maps anyways

any truth behind the people saying it ate up the fuel rail and took out the injestors

Not in my situation, had it sitting in my system from January to June and I had 0 issues, I pulled the pump cover.... inside of the tank was fine, pulled the Injectors they appeared fine, disassembled my regulator it was fine and the inside of my rail was clean.

End/ rumor

That's pretty impressive. I didn't think 1000's could fuel quite that much power. High fuel pressure or high reading dyno maybe?

To the O.P......do it. I switched to E85 on my car, and would never go back. The increased torque and quicker spool time is too good to give up. Not to mention how much it mellowed out my exhaust note. The only obvious pain in the *** is road trips, but that just means you need a support vehicle with some E85 jugs on board, or tow your stuff.

 

I too plan to run E85. I'm getting a 92oct tune as well so i can go out of state, but while i'm here, i plan to run E85 all the time. Its like cheap race gas...theres no reason not to! Also, i'm shooting for no less than 450whp on my 81mm 9.8:1 LS/VTEC. It should be a good time

All the dynojet nut swingers claim his dyno reads high, but I verified my car on a D-Jet 248x and I know 2 others that have also verified their #'s, and they were all within 10-15hp. I dont really focus on the numbers anyway, its the trap speed that says it all.

However, my friend that made 595/420 was using my RC1000's and I also used them, so maybe I got a freak set of 1000's...lol Base pressure on both cars was 50psi.

Oddly enough, he did not run out of duty cycle when he got tuned with just one pump and stock lines at 595whp, and I ran out of fuel at around 610whp with an extra pump and bigger lines.

 

Yeah, the thing is, that walbro's have been pretty well known to run out of gas (pun intended...lol) at 600-650whp on gasoline. With the increased volume demand of E85, hitting that number seems unlikely for E85 given the volume demands.

My perception and belief has always been that walbro's would top out on E85 in the 525-550 range.

I dont' like to get into dyno controversies because it's pointless. Some dyno's read high, and those that own those dyno's never want to admit the fact. I take dyno numbers as a basis, and adjust my own beliefs from there.

Best thing about E85 though, is beast power on the street!

 

if you have the enough injector for it i know i sure as hell would use it but ive never seen it around here plus with that low 8.5 CR you could prolly max out that turbo and injectors on e85

 

I've been running it for 10 months without any problems and I love the stuff. Since gasoline has dropped so much in price and E85 has dropped maybe 50 cents where I'm at, it is getting less and less economical to run E85. My car idles/drives a lot smoother, smells better, and makes more power with E85, so I'm going to stick with it regardless.

 

I hear e85 is hard on fuel lines... thus... is it bad or hard on SS braided -AN lines?

If it was hard on fuel lines then IMO it would also be hard on the stock gas tank and normal fuel rails, and I have not seen this yet. I run a brainded -8 for my feed and the stock feed as my return, I dont know the condition of my return but I have 0 worries about it.

I will update shortly, my friends hatch has had a half a tank of corn in his car for 11 months now just sitting, anxious to pull the pump cover and have a look see before MIR next weekend.

 

E85 is truly an awesome fuel for turbo cars. It makes awesome power and is cheap. We found that on one pump and a set of 1000cc injectors, you'll get around 440hp out of it. Any form of alcohol will corrode aluminum and certain forms of steel but the extra gasoline that is mixed into the fuel will helps not only cold startups but with lubrication. I dont think we should really worry about the corrosion on E85 because it will take a very long time to do so.

 

Been running E85 since july......Maybe 3500k on the car since.Not one problem.Stock h22 with 11psi making 421whp and 315 tq.....Got to love the corn...Plus its almost $2 a gallon right now here.

 

I filled up tonight here in Ft worth texas E85 was 1.56 a gallon it was nice 15bux to fill up

Hot damn 15 bucks in Ft Worth...E85 is looking tempting now..dont mean to hijack but would it still be a good idea to run it on a lower hp setup such as 320-350whp? I dont want much power but if it helps spool and runs cleaner I would be intertested...

lol 15$ to fill up any tank would be nice right now.... E85 seems nice just for any boosted set-up...if it runs cleaner and helps spool then i would def be doin it even running 250whp.....but would it be worth it? do i need to change anything to run E85? im mostly stock for fuel stuff besides Walbro 255 pump.....

From what I have read it will fun fine in a stock fuel system just need to change the fuel pump to something more higher flowing and size your injectors about 30% larger for whatever whp you hope to achieve and of course tune the car for it as well. It seems like a simple conversion and from what I have read there is no real drawback besides fuel economy. There is a e85 thread in this forum somewhere id suggest looking it up.

 

yeah i def will...but what sux is that the only place to get E85 is like 2hrs away.....i havent seen E85 anywhere around me.... :-( well maybe its worth lookin into....

I have a completely stock fuel system except a walbro 255 intank and a bosche 044 up front

If you can't get it locally at the pump, there is no point in looking into it.

 

i have stock fuel lines, a walbro and 1000s and made 498whp on 20psi before the fuel system maxxed out

the car trapped 135mph on 18psi of boost though, my turbo is good for around 28-30psi and instead of going with race gas im just gonna upgrade my fuel system to reach that horse power on E85...
e85 is a win win situation if your comparing it to pump gas.

and if you cant get ahold of a close gas station that sells E85 id recommend to buy a 55gal and take it over there and fill it up, that way you can fill up at home..it's THAT worth it IMO.
