How hard is it if possible to run E85 on the 2008 cobalt ss turbo. As far as what it would take like injectors and such

 

There are no injector swaps for the LNF...

 

ok thanks man

 

you can blend it 2 to 1. Some people around me are doing it but i haven't had any experience with it

 

It'll run 1:1 fine with the right tune. Ask me how I know.

I know one member that is running a stock SS/TC on straight E85 but it took a lot of tuning to get it there. Check out the HP Tuners forum if interested, not for the faint of heart OR THE UNTUNED!!! YOU WILL BLOW IT UP!!!!

 

Wouldn't one use more fuel running E85, thereby losing any cost savings? I would like to see fuel mileage logs to see what the difference would be cost vs. economy wise.

As I have read most cars, even Flex Fuel Vehicles, lose up to 20% in fuel economy. Its because ethanol stores less energy than normal gasoline. It is an interesting concept though, I know SAAB's aero-x was designed to run on 100% ethanol but its was just a concept car. Course it was also designed as a 12:1 compression twin turbo.

 

Yep you sir are correct. When I was running e85 my gas went from 28 mile to a gallon to 20.

 

Was it a cost effective substitute to gas? In my area E85 isn't a whole lot cheaper that normal dyno fuel.

 

I didn't do it for economy. My mileage went from 30.5 mpg avg down to 26.5 on my daily drive with 48% E. (1:1 E10 to E85) No knock retard, more timing & boost, more power & faster times. Increasing boost pressures effectively raises the dynamic compression ratio and reduces the mileage losses from using ethanol. You are correct it contains less thermal energy. Life is a compromise.

 

Here's that thread on hptuners for those that want to read up on it http://www.hptuners.com/forum/showthread.php?t=30353
Fuel economy takes a back seat to performance.

 

Interesting thread. So being ethanol you are running quite rich with that mix but that makes sense since it brings with it an Oxygen molecule. Have you noticed if your engine runs any cooler? I'm not positive but I think it burns cooler than fuel like methanol?

 

Combustion temps would be lower except it's making more power in my case, so it will produce more heat.

 

I'm the one running full E85 on my stock sedan. Thus far there is no performance benefit to running full vs a 1:1 mix. With a mostly (fully?) bolted car like Iam Brokes the point is moot anyway.

 

Run an extra set of fuel injectors to get the extra fuel.

 

This isn't a PFI motor...

 

To what end though? For people like he and I who arent going to ditch the stock turbo theres not much point into adding port injection to the car.

 

Government pushing E85 means less fuel economy and more fillups needed... and therefore more tax money raised while also reducing the number of miles traveled on roads per the tax money.

There is no good reason to use Ethanol (short of tuned performance). You pay more, you lose mileage and burn more, corn-based foods/goods go up in cost, it deteriorates fuel systems, it has to be trucked and can't go by pipeline (partly due to the deterioration issue), and eats away the fuel tanks in some things such as some boats and aircraft.

 

I did not say it was nor did I say it needed to be.

Use something like this.



Connect the fuel supply to the fuel line test port and use a piggy back tuning solution to add more fuel.

You guys are maxing out the DI system right? Well get more fuel pre DI.

 

lol

Off my soapbox.

I meant tax as in the gas-tax included in the price of gas btw. ^

 

Yeah Yeah.

Running E85 lets us be less dependent on foreign oil. We send a lot of money over the ocean that could stay here in the US.

 

You do realize how much fossil fuel is required to grow corn... right? The ROI is almost nill. Corn is a very bad choice to produce into ethanol, yet is used due to politics.

This is topic for off-topic, but the whole way we live really just has to change unless some technology emerges. Everything down to the keyboard I'm typing on comes from oil.

 

It does NOT deteriorate fuel systems and it's 90cents cheaper in my area. So, the economy loss vs savings balances out. Not sure where you got your info, but most cars in the 90's, and all 2000+ cars are ethanol compatible in the construction of the fuel systems. Well, a giant majority are.

 

Here's a write up the State of Wisconsin did on it. It talks about what's okay and what's not with it.

You're right for the most part about most newer cars (many materials were able to be changed to alternatives or specially formulated to help resist its corrosive effects), though some materials are still prone to corrosion. For instance, we can't run anything with more than maybe 10% of it in our boat or airplane, nor should you probably run it if your car's going to sit for a while, due to the ethanol absorbing water and also separating from the gasoline, causing "pockets" of ethanol and gasoline and increased water.

Ethanol also has a tendency to "clean" your fuel system, being a solvent, only to deposit the junk in your engine when it's burned.

 

I agree with that statement 100%. Corn is one of the worst resources to make ethanol. But it keeps farmers employed.

 

im running 50/50 of e85 and 91 all i have to say is wow this is like driving a new car. i was running methanol injection using straight meth before the e85 tune. now im going to bump it down to a 3gph nozzel and go 50/50 with methanol and water with the e85/91
