Perhaps going green doesn't necessarily mean you can't have any fun. Evidence of this fact can once again be seen as the performance and tuning communities continue to look at ethanol for increased performance for a relatively low outlay of cash.

Ethanol, which is an alcohol fuel commonly distilled from corn here in the United States, mixed with 15-percent gasoline carries an octane rating of about 105, compared to the low 90s for the best freely available pump gas. This fact means that engines, when tuned properly and especially when using forced induction, can make more horsepower on E85 than pump gas – and sometimes nearly as much as pure race gasoline.

Cobb Tuning claims to be the first company to outfit a Nissan GT-R for use with E85 fuel and is displaying a dyno graph that indicates very high levels of performance is available when Godzilla is tuned properly for ethanol fuels. How much power? Currently with Cobb's catless midpipe, prototype cat-back exhaust, stock intake, twin Walbro 255 fuel pumps and 800cc Deatschwerks fuel injectors, the GT-R is putting down 574 ponies and 585 pound-feet of torque. After some additional fiddling, Cobb expects to see 600 horsepower at the wheels.

Sounds great, right? Well, hold on to those drunk alcohol-hungry horses for a minute. Ethanol, especially when derived from corn, isn't necessarily the pinnacle of green motoring, and modifications (including high-flow fuel injectors in the case of the GT-R) and required to run an engine with high concentrations of alcohol fuel. Still, something tells us that the promise of cheap and easy horsepower will keep ethanol in the greenlight limelight for the foreseeable future.
