If we could give you the solution to detonation and overheating, and actually increase boost in your ride, would that be something you'd be interested in? Normally, high boost combined with the extreme running temperatures of today's cars spell a short lifespan for your engine. Enter "water injection" and its benefits. This miracle invention (circa 1940) is used to increase compression, allow advanced timing and cool the intake charge in one shot. That said, just dumping water and/or methanol into your intake isn't going to do anything but hydro lock your engine. What's needed is a precise metering and atomizing of the liquid into your combustion chambers. This allows the miracle to happen. Once the mixture is atomized with the fuel, it becomes more dense (kind of like Jonny). The first benefit to happen is that the "dense" mixture raises the compression slightly because water is heavier than air. Second, the alcohol raises your octane level, which will aid in combustion while reducing detonation. Third, the water's natural properties of heat dissipation help get the heat off the piston head, cooling the intake charge.
The funny thing is not a lot of people know about this. Old hot-rodders have been using "water injection" for years, usually just squirting some water from a bottle into their manifolds through an old nitrous jet or something like that. The results always varied, but the overall consensus was that the benefits of lowering temps while raising compression are a good thing. Fast forward to now where injecting the precise amount of water/alcohol and adding the cool feature of "boost safe" (which retards your timing if you run out of solution), AEM's kit provides the benefits of water, with the added boost of higher octane from the alcohol in a safe user friendly system.
