Has anyone ever toyed with the idea of Water Injection to cool the mixture and reduce detonation? Seems like it could be possible and by doing so, one might be able add additional timing to the total.
From what I know Once the spark plug lites the air/fuel mixture the steam vapor slows down the burn rate and reduces the risk of pre-detonation, and since the heat of the combustion has turned the water into high pressure steam this increases the overall cylinder pressure but cooled with less chance of detonation and reduce the chance of detonation? Seems like it could be possible and by doing so one might be able add additional timing to the total.
I also found this.
Spearco, the intercooler experts, offers a water injection system designed specifically for all turbocharged and supercharged vehicles.
This system reduces air charge temps on turbocharged engines with or without intercoolers, and increases air density resulting in dyno proven additional horsepower and torque. On engines equipped with detonation sensor controlled ignition systems, it will maintain maximum spark advance even with low octane fuels producing power gains that you will feel!! The way it works is when under boost...the resevoir gets pressurized and assists the pump in water dispertion. It's very similiar to a rising rate fuel pressure regulator....the more boost you run,..the more protection you will have. Gains of 12% in HP and torque are not uncommon!!
