I was contemplating useing a methonal/water injectionin my jet boat.My marine engine builder says it would be a great addition to my engine as it would reduce the chance for detonation and let you make more power.For the cost of the system I would rather put the money toward an inter cooler.You are relying on too many variables IMO than running a water to air intercooler.Here is a link to ane of the companies that make these systems.http://www.coolingmist.com/
