vacuum pump ?
made 4 passes sunday after converting to alcohol, picked up .13, maybe more with some fine tuning. couple things I noticed, first pass I had trouble breathing, burnouts were excessive due to more power at hit of throttle, snap\crackles\and pops,if you have any where oil can get out it will(dist. shaft\collar) due to increased crankcase pressure.
think I need a vacuum pump, what are your thoughts?
