I scanned these years ago. I honestly do not remember where I got them but I seem to recall they were free to share.





If you have better plans, please post them. When I was in high school I used one of these on my 68 Cadillac to help with knocking.

Back then I was able to pick up a whole kit from PAW for about 30 bucks. The ones I find now are all between $300 and $400 for no good reason that I can figure.

p.s. My body may not work quite right, but at least my mind is sharp and clear.

If you don't have any knocking/pinging then water injection/water vapor induction isn't needed. The newer electronic systems with pumps are mainly used for detonation control on supercharged engines. They will provide water in relation to engine load which the systems you gave pictures for will not.

Are you having pinging problems?

No, no problems. I built many of these back in the 80s.
I found a great design back in high school from some library book. I wish I had those. But it is a simple concept.
