RE>water injection 7/18/95

Yes - In the early 80's I bought a water injection kit from Edelbrock. It had a control box that looked a vacum and rpm (via coil primary) and from that used some sort of algorythm to determine when and how much water to spray. The water mist cools the incoming charge and effective "raises" the octane of the mixture to reduce or delay ping. It also cleans carbon deposits pretty effectively. Since it contributed to reducing pre-ignition, you could advance the timing to get better power and economy. Don't know if they are still avialable, I got mine at a speed shop. With modern engine controls and knock sensors, water injection is kinda put out of business, but it should definitely help older carb fed engines.
