Passive Water Injection

I've been looking for a passive water injection system and don't seem to be able to find any. Anyone out there know of any kits? I'm not looking for the pump WOT active type, but the passive system that feeds a little all the time.


I found this but its way dated for a open system, I need it for a closed system. https://www.ebay.com/itm/Vintage-197...4383.l4275.c10

You could use any meth/water injection kit and just turn the pump on with a switch with a very small nozzle i suppose.

I was thinking about that, not sure what the duty cycle is on a small dc motor like that. My car runs incredible in humid conditions, it will completely blow your mind. I have to build some kind of water vapor system to feed it. Something that would match the conditions found on a very humid day. I was actually thinking spraying the air filter on the outside with a light mist. Something that could run for maybe 4hrs at a time without running out of water or burning out the pump motor. This would create similar conditions that a humid day creates. If you drove it you would understand why I need to do this.

Here is the science behind it

Spraying the filter wouldn't be a good idea that would restrict airflow.

Summit has these economical fuel pumps. Maybe with a resistor or a potentiometer you could reduce volume. Not sure how long they would last with H2O but it could get you through the R&D portion of your experiment. I've got to ask are you SURE you're not attempting to mask some underlying problem? My V6 pulls hard if it is 50* and rainy or 100* bone AZ desert dry. As much as I enjoy a good MacGyver project I'd hate to see you do this just for mechanical exercise.

hey barb, maybe start with a wiper motor and nozzle It down. it already with stands alchohol related fluids. and like arizona28 said you could choke the voltage down some way . heck you could hit the bone yard a look for a set up with the tank and all . just saying . the oldman...........

Thanks for the suggestions. I can't find anything wrong with the car other than the normal LSPI and pulling timing at low rpms. I'd say the humidity adds 25 plus hp, its a noticeable boost.

The inlet duct if you're running the stock air filter box or in the top center of the cone filter on an aftermarket CAI.
