> Water injection is the spraying of a fine stream of H20 into the intake system. Heat absorbed upon vaporization of the water has a strong cooling effect on the hot compressed air exiting the turbo. The reduction in intake air temperature reduces the tendency to knock.

> Don’t be too hasty to create a margin of safety of detonation based on an unreliable device. Water injeciton is best used when boost levels over 6 psi are deisred but no intercooler is present. Do not allow a situation to exist where the water injector is used as an excuse for improper air/fuel ratis. All things considered, you would be far ahead never to have hear of a water injector."

We’re not talking about water injection… Water isn’t 100 octane, in fact it isn’t a fuel at all.
