The advantage of water/alcohol
is a lower incoming air charge. It is said for every 100 degrees of lower temps there is a 10 HP power gain. My engine does not have an intercooler. A cooler for my 7.3 Ford diesel will cost about $700 with piping, plumbing and lots of fabricating hours. War airplanes used water/alcohol for a cheap horsepower gain. This cooling method is just for the long steep pulls. I know more horsepower is the best method, but horsepower is not free. The parts are fairly cheap to assemble a system. Propane is good too.
