What do you think the best power/drivability combo is?

LOL! Luftwaffe. N20. They would run on the bottle 20-30 minutes straight! That's if they didn't get shot down. Emergency power! Another one they used was water/meth injection. They had to deal with poor fuel. 87 octane. Allies had 100-110 octane. So much lead plug fouling was a problem.
