Quizá el alcohol (etílico o metílico) sea bueno para subir el octanaje, pero creo que es bastante menos energético que la gasolina. Desde luego, su combustión es mucho más lenta, y eso no sé cómo afectará a la propagación del frente de llama.
Preguntad en Brasil, que usan alcohol para mover algunos coches. Pero para un deportivo, no creo que sea lo más adecuado.

Otia,impresionaleer estos nombres Focke-Wulf Fw 190, Kurt Tank, Messerschmitt Bf 109 estos son palabras mayores de la aviación germana, la duda que tengo es que no creo el combustible para un BMW 801 o Junkers Jumo 213 valdra tal cual para un C20NE.

An interesting fact is that a water-cooled engine is often described as mild, compared to an air-cooled engine, which is regarded as severe in its octane, or PN demands *these are highly supercharged, high output engines, of course* Anyhow, grade 115/145 avgas would effectively be 145/145 in a mild engine, allowing around 40-45 psig manilfold pressure, with intercooling, before detonation.
Then, of course, there was 150 PN fuel, which the brits used inpreference to Nitrous. Couldnt catch a V-1 with a Spitfire using 100/130 gas, but fill it with 150 grade... no problem
Further tinkering yielded 270PN fuel, which they never
were able to make detonate, although they busted lots of engines trying. Allison used some of this stuff mixed with 100/130 to up the power on a 1710 from around 1500 HP to 2800 HP "for a short period" Bits were coming out of engines, but not from detonation, they just werent strong enough for the forces of normal combustion
Merlins put out 2200 HP on about 45 psig manifold pressure, so the 1710 was getting about *SWAG mode* say 65-70 psig at the intake valve.
