Water Injection
The latest project is a custom dual-port water injection installation.
These three pictures show the solenoid and pressure switches. The blue lines are water lines and the red are the air lines.
Here's the same after the wiring:
It turns out that a Saab 900 windshield washer fluid reservoir fits nicely into the spare tire cavity in the trunk, with minor modifications of course. Here's are a couple of shots of the reservoir mid modification:
And here's a shot of the reservoir and pump installed in the spare tire cavity:
Here's a shot of the wiring schematic:
Here's a shot of the master switch, boost gauge and status LEDs from the two stages.
Here's a shot of the first round of turbo pipe with the injectors installed:
I chose to install water rather than nitrous for several reasons. I could have installed a wet nitrous solution, which might have even been simpler with so many bolt-on kits available. The water is cheaper, and it's not as hazardous to work with. It only needs a pump, and doesn't require the heater, pressurized tank, etc. Overall though, I chose water injection because of it's endurance. Nitrous is good for a couple of shots, but won't be there for a whole race. I've seen 1/4 mile turbo cars running +50psi using water, so I know the power is there.
