I know the general public should never be expected to subsidize enthusiasts, but E85 - available in many places for under $3/gal - has many of the same performance characteristics as $20/gal race gas for performance automotive enthusiasts.
I'm all for the peaceful and orderly dissolution of the entire US federal government, as involuntary taxation under implied threat of violence is theft, but until then, thanks for the deeply discounted race gas, fellow taxpayers!

- IrishTechie 1y agoIt's been a long time since I dabbled, but from memory the likes of E85 is good for fixed load use (eg. drag racing) but not great for variable load (track racing cars, motocross etc) because petrol has a wide range of evaporation points compared to the much narrower range of E85.

It also lets the engine run cooler despite burning hotter precisely because of those evap characterisics. That's not to say there are no downsides. It's less energy dense so you need larger injectors or a higher duty cycle, you get less mileage, it's extremely hygroscopic, it has different corrosive properties, and a different stoich ratio so most vehicles need some amount of modifications and tuning to properly utilize it. But all in all, it's wildly economical alternative to traditional high performance fuel.
