ok, im not making a hybrid right now(i dont trust my combustion skills that much yet and i like living) but i was wondering, after u do a 2x or 3x mix how do u now how much air to put in with the propane to keep it at the 4%, is there an equation or sum like with a propane meter??

alright, with normal atmospheric pressure at sea level you have about 14.7 psi, when you inject say a 2x mix you need to double that air so you'd need 29.4 psi at sea level check out boogie's site and lucky13's site, i believe they have some more detailed explanations
