A line is run up to the engine compartment and fitted into the air tube for the CAI just ahead of the throttle body. There is a pump integrated into the ethanol tank, and a switch installed on the dash to arm and turn the flow on/off. This rig supposedly adds an instant 30HP. My concern is the instantaneous change to octane and how that might affect the ECM, etc? Anyone have any opinions on this type of setup? |
..is it really ethanol, or possibly methanol? I think most who use this use methanol, since its distribution is not regulated. My limited understanding is that it is used under wide open throttle, so that you only have to adjust your tune to give a little more spark under that condition. The alcohol serves to keep the engine from knocking (detonation) so that you can advance the spark safely. From the few articles I have read, it works fine, but there needs to be a failsafe or warning, so if the tank is near empty, you don't start putting your foot into it. I am guessing that it is mainly used by those who have really upp'd the horsepower of their engine, kinda like an insurance policy. I hope some others weigh in on this also, since all my knowledge is just from reading.
