e85 turbo

[geoffinbc]

A good alternative to E85 is Propane. It has a HIGHER octane rating of 110 versus about 105 for E85 and contains about the same BTU's. It burns clean and is very cheap and with an engine designed with a compression of 12:1 or higher it will make about the same power as gasoline but you could still add boost too.

That link is a quote from a bunch of other websites. And the fact that E85 is not corrosive is true, IF there is NO water present. But since E85 absorbs water right out of the atmosphere then it will become corrosive.

since I'm experienced with this figured I'll jump in...

I ran E85 on my last turbo setup for a year. I had NO problems

yes, you do need injectors 30% bigger than you would run for a gas setup

yes, you can use the TGP tune just need to modify it for your car

I have a 7730 ECM and didnt have to rewire anything for it. you literally install your injectors and the 2bar map in place of the 1bar thats it. the TGP had a EBC yes, but I never used it

before I even messed with E85 I submerged several fuel system components in a few gallons of it. this was.. 3 years ago now I think. none of them have any issues. there are some materials that are better suited for E85 use, but, if your car is designed to run on E10 (which is most any car you see) you can run E85.

ethanol is not a highly corrosive fuel like methanol is. if something in your fuel system is on the verge of rusting through of course E85 wont help it. but so what that means you were going to have an issue regardless before long

so am I saying dont bother looking over your fuel system from the pump all the way to the injectors? no. I'm just saying it seems people worry too much about it. if you need to make any changes its likely to be small ones. the only major overhaul I would do is if you had a gas tank known to be problematic with E85. installing some stainless valves would be a good idea if your going to run E85 for a long time

since E85 cleans so much you will likely need to change your fuel filter from all the crap gasoline left.

if you go with E85 keep in mind you can run more spark advance. the stuff I get around here is ~105 octane and like $1.80/gallon. so it worked for me

E85 is 5cents cheaper than regular here...... And the state requires all state vehicles to run it... Our tax dollars pay the companies incentives to make it otherwise they wouldn't because it costs so much to make... You can't get any gas that doesn't have 10% in it anymore here either.

But for boost/etc I bet it's nice.

it is AWESOME for boost.

[scott0999]

that does suck when its barely cheaper than gas

I had this crazy idea once that if people would stop being scared of E85 and actually USE IT, it would be more plentiful and price in states w/o corn fields would go down

but oh well what do I know lol

[IsaacHayes]

Yeah I tried explaining it to some people here that have flex vehicles that they don't save money but end up paying more, but they don't listen and just tell me "It's 5 cents cheaper!"... LOL

the sole purpose of E85 is not to get better mileage. and I would agree alot of people prolly think their saving with E85 (especially in states where its barely cheaper)

theres alot of factors. E85 w/ high compression and the right spark advance can yield near the same mileage as a gas engine

[RedZMonte]

I have a TGP ECU/Chip if your interested. Its in my garage ready to ship. Let me know if you are interested. Its cheap.

not quite. the stoich AFR for E85 won't allow anywhere near the same fuel economy numbers.

you could probably end up paying about the same amount to travel the same distance, but E85 will disappear faster no matter what you do.

theres some info from people that have tested theirs. im just saying if the setup was actually built for E85 it should be able to get better.

[robertisaar]

info for anyone that wants it

cliffnotes version:

pure gasoline stoich : 14.64:1
E85 stoich: 9.85:1

that's a 48.6% difference. most vehicles will realistically see a 20-25% drop in fuel economy. there are freaks out there that will lose only 10%, and those that will lose 50%. point being, 1 gallon of gas in a normal, modern motor will always go further than 1 gallon of gas in a motor designed for e85, simply because of the volume of fuel being injected.

You mean like how they are trying to ban guns?


I thought the sole purpose of E85 was to stretch out what gasoline we have and to help us try not to depend on foreign oil so much.

gun banning: tell that to dick cheney, just make sure you're about 100 yards away first...

E85: yes, that was the official reasoning, and it can do that, since 85% of what is coming out of the exhaust isn't petroleum based.

unofficial: who knows, maybe some farmers got the idea that it would make corn prices go through the roof, doubling or tripling the amount of cash they make every year.

it sure as fuck is not for environmental reasons though... look up what ethanol produces as byproducts, you'll see weird stuff, like formaldehyde. i don't like being embalmed when i breathe...
