What has to be done to run E85 in the C5/C6?
Corvette Z06 E85 concept
The Corvette Z06 E85 concept pace car is based on the production Z06 – already one of the fastest and most powerful cars on the market – and blends its performance with the high-octane, renewable alternative fuel that is derived from a variety of crops grown across the United States.

E85 is blend of 85 percent ethanol and 15 percent gasoline. Its benefits include reduced emissions of greenhouse gases and a reduced dependence on petroleum. GM is the leader in E85 production models, with more than 2.5 million E85-capable cars, trucks and SUVs on the road – with more on the way. Chevrolet offers seven E85-capable models in 2008.

Apart from the fuel system and powertrain controller revisions required to run E85, the Z06 concept pace car is mechanically stock. It is distinguished by a unique Gold Rush Green color-shifting paint scheme that changes between hues of green and gold when viewed from different angles and in different light. A subtle checkered flag pattern also is part of the paint scheme. Safety equipment and strobe lights are the only other equipment added to the car.

Research ethanol. It is not all that some want you to believe. Ethanol contains 77,000 BTU/gallon of energy whereas gasoline contains 115,000 BTU/gallon. So your fuel mileage will go down by the same ratio (for 100% ethanol).

It takes huge quantities of water to produce.

If the entire land area of the US is planted in corn this would only supply 5% of the energy need in the US.

Corn is about the worst plant to make ethanol from.

The emissions advantage is being revised.

It does produce more power because the ethanol molecule contains oxygen. Therefore you can put more fuel in the cylinder.

The octane rating is much higher but octane is not a measure of power.

 

I've heard the opposite...worse power and gas mileage

 

Tell this to Al Gore and his lune followers.

 

I love E-85 in mine. Ya it does lose a couple of miles per gallon, but so what. www.rune85.com also check out the sig

 

I've been running mine on E-85 since July of 2006. Mileage goes down a little bit. You don't need to worry about detination which allows the timing to be pushed further. If you have it available in your area it is something to look into.

 

Getting ready to switch mine over to it. We will see what happens. You can still run gas also if needed

 

E85 is a joke and will drive prices of everything up...read the data if you want to be friendly to the enviornment, drive less or quit driving and don't use electricity, oil, gas etc...otherwise have no life or die my 2 cents is we are a free country so use what you please but don't try to push your BS on me -listen up al gore and friends.

 

Edit:

The sentence: "It does produce more power because the ethanol molecule contains oxygen."

Should read: "It can produce more power if the engine is setup to run ethanol fuel."

Superchargers and turbos produce more power because they ram more air i.e. oxygen into the cylinder. More air, more fuel ,equals more power.

Ethanol contains oxygen so more fuel can be added into the cylinder. And with an octane rating as high as 149, higher compression ratios can be used.

The link above is a very interesting experiment running ethanol. It is a very well thought out experiment and contains much information. He found that the stock fuel injectors are not large enough to maximize the power from ethanol fuel in the non E85 rated vette engine.

Don't get me wrong. I am not totally against ethanol as a supplement. But it never will be a replacement. However ethanol from corn is foolish. The US has not had an effective energy policy for the past 35 years. Both Dem's and Rep's are to blame. Simply put the econmics of alternative fuels does not even come close to gasoline. And it won't until the price of oil rises significantly. In 3 minutes at a gas station you are putting a huge amount of energy in your tank. Do you think you could put that much energy into a battery in 3 minutes?

 

I switched my carbed 68 Camaro to e-85 and gained 4 tenths. Very simple to do. I changed carb jets. Are injectors on a Z06 big enough to run e-85? Will our fuel systems supply enough fuel? If those parts will work stock it is probably worth getting a tune for. e-85 is only $2.39 a gallon so even with reduced fuel economy it would be a good deal. I believe, but have no scientific evidence, that the oxygen molecules in the fuel are a big part of the added power in my Camaro. I also think the fuel burning cooler helped my power and consistency.

 

The Z06 is a supercar and will not have any performance benefit from E85.

 

Our E85 Ford Explorers (V6) that are used at my home station for patrol vehicles get a whopping 7 mpg. I'm not impressed by E85.

 

E-85 should give us more power. Anytime you can get more fuel and air into the engine it is a good thing. Also because of the 105 octane we should be able to advance timing. Both should increase our power. Engines all respond the same supercar or not. I am not sure if our stock fuel systems can handle it because of the increased fuel volume required.
