Default Confirmation that LT1 will be flex fuel

These guys pulled the RPO code, and voila: E85 capable

Yeah, someone posted that a few weeks back.

I can't wait to see what kind of numbers it makes on FF.

And does anyone know why they make vehicles FF? Hint, it has to do with how our government rater the fuel economy for CAFE purposes (not seen on the window sticker). It's an interesting topic. All those Suburbans, large pickups etc that say FF on the back are credited with a fuel economy in the upper 20s. That is why the auto makers did not fight the government mandate to raise CAFE over the next few years.

The article here is old but explains it better than I can....

From what I read when using E85 the engine is making more power than with pure 93 octain gasoline. Interesting!

I also understood that was a fact, I wonder if the estimated 450 HP is on 93 or E85. I think when the numbers come out the LT will make a little more then the 450 to start with.

I really really really want this to be real however, we need to understand that the LS3 is also Flex fuel however, it's only in the truck/SUV line, but for some reason the Camaro and Corvette don't get the feature.

As you can see from my tag, that i'm a E85 fanatic, so i need to be sceptically because if this ends up being real... I will have a heart attack! LT1 is turning out to be my dream come true!

The 450/450 will be graded on the min required fuel. Very well could be 87 octane...

If it helps those who can find it, great! I see it as a real non-issue as I've never seen E85 for sale anywhere.

Blue,

You must not live in the corn belt. Here in IL E85 is readily available, gasoline without ethanol added is scarce, and diesel gets blended with soy oil which is OK in summer but not so great in winter (increases the cloud point and gel temperature).

And the "opposite" list of stations with pure gas for use in older vehicles, lawn care equipment, and for those who want to maximize miles per tankful: http://pure-gas.org/

Same here, never seen it in two years of driving my flex fuel Silverado.

There is E85 in your area......... 7 locations according to this link

said this in other threads.

its the computer that makes a vehicle flex fuel, not the motor. all motors will run on e85 as long as the system provides the right mixture of air to fuel.

personally i hope the C7 has flex fuel ability, though im a bit dubious about the amount of power it will add.

there seems to be a consensus about the motor being engineered for forced intake, in which case if such a car had flex fuel capability, the results would be significant. and maybe thats why its flex rated, for the future high performance versions of the base car.

Well, I don't know about your computer but on mine, the E85 symbols don't show any other info like which gas station it actually belongs to.
EDIT: OK there is info but it is white lettering against a white background. WTF?
I don't presently have any E85 vehicles anyway so it's no big deal to me.

If I understand it right anything that comes in contact with the E85 has to be corrosion resistant materials, like stainless steel. So all of the fuel lines and associated parts have to be upgraded to withstand corrosion. BTW the octane rating for E85 is around 105.

Currently this holds true for me

Despite rumors or hopes associated with E85 and higher HP#s, ethanol in motors not designed for it can have negative effects that go from bad to worse.

Anything above 5% in my 120 inch blueprinted V twin will shut it down (until fuel system is drained) that today includes most high test fuel in my area. Other motors that will run on it do not sit well with it in their fuel system........ especially boats!

Other side of the same coin is rising food costs for those who can least afford it

It must be a browser issue, lettering is black on mine. (Firefox current release, pretty much default setup).

I will await others' experience before trying E85 when I buy a C7. For most flexfuel vehicles it is either a wash for performance or a loss and there is a drop in MPG given the lower BTU content. DI already allows higher compression/advanced timing with normal octane levels so I await results on how the LT-1 performs with the increased octane of E85. If the engine was designed to take advantage of the increased octane then E85 will be interesting.

For those who park their car over winter or don't drive it for long periods of time they had better be consistent in using a fuel stabilizer/treatment.

San Diego is a little barren for E85 stations. I think I saw three in the entire county.

I would love to have my C5 tuned for E85. Would be an easy 50rwhp with my setup, but it just isn't practical in my area...

Why anyone would support burning fuel derived from food sources is beyond me. This world is suffering from lack of food and not from the lack of fuel for combustion engines. To produce the billions of gallons of ethanol to replace fossil fuel would require every square foot of agricultural land in the USA. It is a ridiculous scam foisted on the gulible american public by a socialist, out of control government. There is no way that alchohol can produce more power than fossil fuel unless the engine is made to run on alchohol alone. Ethanol has 20% less energy than gasoline and 50% less enerygy than diesel fuel. Corn should be used for food and not for fuel,
