I am building a turbo project and getting ready to do the fuel system. i have some toyota budies running E85 because of the extremely high octaine rating compared to the cost (101-103 for $2.70 a gal.) it beats premium and is like 1/4 or less the cost of race gas. what do you think? I haven't bought any injectors or a pump yet and running a new fuel line is nothing for me.

 

which ebay kit did you buy?

where does it say anything about ebay?

 

probably a good guess.

 

Its possible. Remember that you will use more E85 per mile than regular gas so even tho it is much ceaper per gallon you will be using more so it comes out to be about the same, maybe a little cheaper.

98vtec uses e85 iirc.

You will def need to tune for it.

 

I recommend going with RC 1000cc injectors with the Aeromotive Compact EFI regulator and a Bosch 044 fuel pump with a -8an feed line. You do not want to run the Aeromotive pump. It is not rated for alcohol and it will burn out.

Furthermore with E85 you can run higher compression.

refrain from posting invaluable crap.

 

hey Hu thanks for the advise.

and to Apex1972 thanks for being a hater, douche!

 

Gniddy:

My understanding of E85/Flex-fuel is that E85 or 85% gasoline mixed with 15% alcohol is a very corrosive mixture. The engines manufactured to use this mix have a lot of special components in the fuel supply, intake and combustion systems to prevent corrosion in the intake and combustion systems of the modern IC engine, due to the affinity to water in this mixture. I am using several oz. of ATF in each tank of fuel in my 2nd Gen Prelude to hopefully, offset those corrosive effects.

 

ethanol is not corrosive.

 

First off not to start a fight but c'mon E85 is 85% Alcohol and 15% gasoline! And I'm a girl that knows running this is not corrosive and the only benefit other than higher octane is that it is renewable and we make it here in the states, we dont have to buy it abroad! The second thing is that alcohol burns colder so your O2 sensor wont read it correctly therefore your car may burn either too rich or lean take your pick on the temperment of your engine... And dont try to use it for mileage cuz it isnt any better you actually use more so keep that in mind.

i am not concerned about possible damage to fuel sysytem since it hasn't been purchased yet. i am also not concerned about possible wear on engine internals b/c everything is new, top of the line stainless crower. i will be running an AEM EMS standalone w/wideband controller so i should be able to compensate for any irregularities in O2 or other sensors. aside from a couple of posts here i see a lot of speculation.

i will rephrase the question. has any one actually used or know someone (actually seen thier car and their setup) that is/has used E85.

AS FAR AS I KNOW, with the mods i've done to the engine(bored to 89mm, crower pro I-beams weisco pistons, oversized valvels and stainless retainers with upgraded springs) plus a nasty turbo setup (still in the works) i should be able to push 500HP on E85 where i might be at 600 with C-16 race gas and only 400-450 on pump premium. C-16 is mad overpriced. E85 is higher octaine than premium so even though it is not quite as efficient as regular gas it burns cleaner and has potential to make more power if built and tuned right.

I think you mean to say "refrain from posting useless crap."

yeah thats what he meant, I'm sure. I love how everyone has to prove that they know more than the next guy.

Incorrect info in there....not rated for METHANOL....not ethanol. Methanol is corrosive, ethanol corrosive properties are VERY mild. Aeromotives, Walbro's, Xenocrons....I've used them all with E85...they all work fine.

Same goes for stock fuel lines, seals, etc. I've used it personally, tuned it personally, and I'm speaking from first hand experience, so take from it what you will.

Incorrect there. O2's don't work based on heat. O2 sensors are lambda sensors, they have no idea what fuel is being burned, they only know how to read an ideal burn ratio (1 lambda, and the deviation from there).

I've tuned several E85 cars, and I tune them as gasoline. If you tune a turbo car to .82 lambda under load on gasoline, then you tune it to .82 lambda on E85. There's no difference in tuning whatsoever. The differences lie in HOW you tune for power, but using a wideband to do it is straightforward.


My experiences with E85 are that there are very generous gains in torque and spool time, as well as increases in power overall due to the ability to run more ignition timing.


Everyone needs to understand that Ethanol isn't METHANOL. Methanol is corrosive, will cause blindness if consumed, and will eat a fuel system...aluminum alive. This is NOT the case for Ethanol. Ethanol is far less corrosive and has been an additive in pump gasoline for decades.

I've run it, I still do, and I like the characteristics of it. It burns clean, there's no carbon smoke with boosted setups tuned rich for the street, I dropped several hundred rpms in spool time, and gained a bunch of torque. In my Delsol (LS/vtec, GT3082R, 880 Precisions, Xenocron pump) I got 18mpg with 2 hours of tuning doing mixed driving.

It works, and having higher octane gives piece of mind in moderate power setups, knowing your not flirting with the ragged edge of the gasolines stability.

 

Not trying to brag, but I'm pretty sure I was the first :D but sadly I can't keep it any longer

Sorry to burst your bubble there bro, but I tuned cars on E85 beginning in early 2006, as have many others. Your certainly not the first

Nice car though

Good info

 

Check out Greg H's car, there is a post on it somewhere in the top page or 2, he runs E85 on his turbo 4th gen, makes 640 whp, street driver car, about to break 10's on the track, as he ran 11.2 with a nasty ignition issue. 1600 cc injectors, aeromotive 1000 pump, AEM EMS, prologger etc. And his 640 WHP is on only 21 psi from the PT-67 turbo.

 

This looks like an interesting video about E85 in non flex fuel vehicles. Sorry if this is old news to the know it alls.

Acutally there is a guy on preludeonline thats running E85 on his turbo h22 his sn is Qevon
