GM is supposed to be into Flex Fuel in a big way. E85 is supposed to run 105 octane. Seems like high performance engines would benefit from Ethanol.
I wonder if a conversion kit would be possible.

i think that e85 will have considerably less btu's, power, per pound, and mpg is going to go down. and unless engine is "tuned" for it, horsepower is going to be down also.
think so anyway.

It'd take more than "tuning" to keep hp up too. You'd need to bump the compression ratio up to about 12:1 to get the power back. But then it wouldn't run on straight gasoline any more, losing the "flex-fuel" capability.
When the 50 cents a gallon federal subsidy runs out, it'll be more expensive than straight gasoline too.
