Indy used this in the early 80's at 85% and was making 1000 hp per liter between 50 and 75 psi of boost. They would have used 100% I think but there was a octane limitation rule. I bet you could even replace the methanol in an injection unit with it.
I might be thinking of something else.......but I think it was the tire manufacturers that got on indy's case about the fuel being used. The cars were making more and more power and the teams were blaming the tire makers for not making a product that would last. Eventually, the tire manufacturers told them to switch the fuel or they would no longer supply tires.
