Questions on switching from racing gas to alcohol
I'm considering going to a Procharger on a 14:1 compression BBC, 565 with 950 h.p. I'm told that if I switch to alcohol, I will not need an intercooler, and the compression ratio will not be excessive on alcohol. Currently I have a 5 gallon fuel cell in the rear of the car. I know that I will have to install an adequate fuel pump, but...can I leave the fuel cell in the rear, or do I have to use a smaller tank near the front, like most alcohol cars have? Thanks for all input.

Methanol all the way. I went from gas carbs (well tuned) to injected alky and gained 2.5 tenths. From the first race of the year to the last pass I made, variance was not more than .05 all year, even going from 8000-9800ft DA.....Carbs did well, but not even close to what I have now....

Du kannst den Tank hinten lassen, ein Umbau nach vorn ist nicht zwingend nötig. Viele Methanol-Setups fahren problemlos mit Hecktank. Wichtig https://sgcasino-deutschland.de/ ist vor allem die Kraftstoffversorgung: Methanol braucht deutlich mehr Volumen, also starke Pumpe, größere Leitungen und ein gutes Rücklaufsystem. 5 Gallonen könnten schnell knapp werden. Die 14:1 Verdichtung kann mit Methanol funktionieren, aber nur mit sauberer Abstimmung und Vorsicht.
