The volumetric efficiency of my motor peaks at 113 % allready. IR's sure look cool but the lack of room and air cleaner issues prevented me from considering that avenue. One more thing, you can run the efi leaner than the carb as you don't have the same distribution issue's even at high rpm. A carb has to be rich enough to cover the leanest cylinder. I am running my efi at 13.2 to 1 with no problems. scott
