water injection Options

Marcus is right about the water being a solution mainly for knock. If your EGT's are too high, you need either an adjustable fuel pressure regulator or bigger injectors.

Or you could run an alcohol/water injection setup with denatured alcohol (ethanol) or methanol. Both of these have around a 100+ octane rating as well as having almost the same cooling effect as water. Downsides include flammability, and methanol is pretty corrosive. Most of the Buick guys I've talked to seem happiest running 100% denatured while tuning their fuel back a bit.

The system on my car has a 90PSI pump out of a mid 90's F-150. Lifetime warranty at Autozone, around $90 I think. It worked well until the check valve locked up, and I decided the problem was with the nozzle and took a drill bit to it. :roll: Needless to say it doesn't mist very well.

I'd really like to retro-fit some 2-3 large Aquamist nozzles on the system as well as an in car PWM for controlling the output of the pump.
