FYI, I have been doing research in making my own water injection kit. I have heard that WWII aircraft had water injection, and the setup was a progressive system
The components are:
- Sealed reservoir tank
- Hose from pressure side of intake system to tank (after turbo)
- Hose from tank to low pressure side of intake system (before turbo)
- Spray nozzle on low pressure side of intake system
- Bleed valve for tank
As boost pressure rises, the pressure in the tank rises, forcing water out through the injector. Adjust the bleed valve to change the boost level at which the nozzle starts spraying water. Adjust the nozzle sizes to control the amount of water injection. More boost equals more water injection when you need it.
I have not tried this system myself yet, but plan to within the next month or two. Thoughts?
