Been doing this for quite some time on many makes and models of cars with forced induction incorporated in them. Anyone done them here yet? I'm assuming not since there's not any options currently available for larger injectors or pumps....

Anyone thought about it though, anyone try it?

Something you guys may want to look into especially if you plan on making some big power.

I've been using E85 on various cars for quite sometime so I'm well aware of its characteristics, factors, benefits, etc....

Just trying to see if anyone has tried it yet on the the ss/tc or if anyone is interested.

 

in truth isnt it a waste? just burns quicker making you have to fill up more

 

The LNF isn't designed to run E85.

 

NO.... Higher the octane the slower it burns.

E85 is rated at 105oct.

Octane is not where E85 shines though. What makes E85 so beneficial is its cooling characteristics. Its a really cold fuel. These characteristics allow you to fun higher timing and boost levels therefore making more power.

However there is some downsides to E85.
-Not available evey where like regular gas
-Requires twice as much fuel at WOT thus you will need larger injectors and more pump.

Why not?

 

the whole "it will damage the engine" bit is crap.

the OP is correct in a lot of things, the main issue, however, is that the car can't deal with the mixture, it's not a flexfuel car. so, if you set it up for e85, you'd have to run e85

 

cause gms little cute flexfuel badge is not on the car

and thanks for the info on E85!

 

we only have like 3 stations around here that supply E85. Isnt it up there if not more then Race fuel though? pretty sure its pretty expensive here but i dont know.

 

They say E85 can slowly eat away at fuel lines and other parts of the fuel system so it's a no no unless your car is designed to handle it. Most E85 vehicles will have some sort of label on the gas cap to let you know. The LNF does not.

 

i have heard this too^

 

This is true....unless you made two separate maps (one for E85 and one for gas). Even then that raises a few other problems like having to run the car until its dry OR running a separate fuel cell you can switch too but it is possible

NO. E85 is really really cheap. Average price for the U.S. is currently as of today $2 a gallon.

Not entirely true http://www.youtube.com/watch?v=HuOs1yap8mU

The vid is no joke or scam. It is true. We see it on a daily basis. Keeps internals and fuel components like new. Have yet to this day see otherwise.

We've taken a look into flex fuel cars from the factory and the materials used for the fuel systems are the same as non-flex fuel vehicles. Secret lies within the tune and EFI Calibration nothing more

 

It's closer to 30% more fuel required.

We wouldn't be able to run E85 effectively without swapping to larger injectors or significantly increasng the fuel pressure.. The pulse widths would be too long on stock injectors/pressure.

 

Well if that's true then by all means, but I wouldn't run E85 in any vehicle unless it's designed to run it.

 

Thats why i mentioned previously that there is drawbacks being that larger injectors and pump (minimum) will have to be upgraded and being that there isn't any available YET it poses a challenge.

For n/a vehicles we seen the 30% increase in fuel needed but we've seen more then that needed for forced induction applications

A simple tuning session (making a new map) and you'd be designed for it once you get the fuel delivery issue taken car of. Doesnt require special lines or anything of that nature just a larger pump or (pumps) and injectors.

 

That's the problem with DI, parts like that aren't easily accessible. I wasn't saying it's completley wrong to run e85 but the car from the factory wasn't designed for it. If you modify for it then sure. But in some places E85 is not much cheaper than gasoline so the cheaper fuel cost goes out the window with the decrease in miles per gallon with running ethanol fuel.

 

Yes but keep in mind the benefits and advantages of E85. Look what extra you may be paying for IF its indeed not as much expensive as regular gas.

Yeah we just finished swapping my buddys sti over to e85 and he got an extra 15hp and now doesn't have to run water meth inj. Or 101 trick fuel. Camtuning here in town has been switching many sti's over and have seen great numbers out of them...personaly would loveto swap over if this wasn't my daily driver

Oh yeah his sti hit 517whp..its hella fast

 

Very nice! Not looking to do anything crazy with the Cobalt so I won't need bigger injectors but that's great news for the members looking for big numbers.

 

I thought that there was already someone tuned for it on here. and our vehicles are equippd with the newer seals if I can rember correctly this disscusion has occured its all in the tune.

 

Isn't our fuel tank polycarbonate? Versus the steel found in true E85 vehicles.

System component and seal argument aside, in theory......we have enough flow overhead to support the increased volume demands (at near stock power levels). Also remember that the TC is equipped with a wideband O2 sensor. So it should be able to compensate. I'm not sure I'd want to try a full tank, cold turkey. Running 50/50 with 93 octane and E85 however......might be feasible. In theory anyway.....

 

I dont see what the point is to run E85 on a performance car. If you wanna run E85 buy a flex fuel car. You dont buy an ss/tc for gas mileage anyways! At least i didnt hahah

 

It cost more in the long run. Not worth it.

 

E85 does have performance credentials. Just take the Koenigsegg CCX for example -- you can get one tuned to run E85 and gain over 200bhp.

 

The reason why you use it in a performance application has already been stated (cooling characteristic, ability to add more boost and timing, keep internals and fuel components like new see the vid, and more octane) With all that your less prone to preignition/detonation/knock.

E85 wont improve your gas mileage BTW........ so you got that a little backwards.

Weather is worth it or not is one's opinion.

You only use more E85 at WOT then you do regular pump gas. So lets say by the time its all said and done you spend $3 on gallon and apposed to the $2.75 for pump gas....is it really that big of a deal? Its like running race gas all the time AND ITS BETTER FOR YOUR CAR

 

I would love to run E85 in my car. A ton more timing and more power.
