I have a SMC kit I was using straight alcohol with. With the stock side mount and a small 16g I was tuning for 20 psi on 92 octane no knock or 25 psi using 100 unleaded. The car is an AWD and would torque steer with 7.5" rims in second gear. I have since switched to a 20g and a FMIC currently without the SMC kit. I am slowly and carefully tuning the car back to the same power levels I had before. I would say that you can run extra 5 psi of boost using alcohol on a DSM once you get things figured out. If propane could give the same results I might choose it over alcohol. Alcohol seems to oxidize any exposed steel IC pipes on the inside. I would really pour the alcohol to it, enough that I would lean the car out (fuel) at mid RPM and gradually richen it up to max RPM. Yes it really does work, but you really need to watch what you are doing.
