How about running a mixture of ethenol instead? It burns colder and should be cheaper.  If tuned correctly it should create a lot of power.

Bacardi 151 duty free sounds good :P

*chuckle*

Thats true, but if it were better, why dont we all use it? Heres why.

The optimal air/fuel ratio for petrol is 14.7 to 1

The optimal air/fuel ratio for alchohol is 7 to 1

So at 10c a litre cheaper it sounds better, but you use twice as much.

And its low octane, meaning it will ping at a much lower latent heat threshold.

Meaning it will self ignite at a much lower pressure/temperature.

Not much good as a fuel for high performance.

The reason top alchohol cars have so much success and power using it (100% mix) is they run it at 7:1 and at this mixture, it DOES cool itself quite well. But they still dont get as much power per litre as petrol.

And its corrosive to some metals...
