Rotary Car Club - View Single Post - auxiliary injection-who here has it?

Disregard. I just tested the water injection and it DEFINITELY works.

I had 25psi from the air compressor (I probably should have tested it at a lower pressure too but whatever), and before even revving the engine it was spraying water when I gave it pressure from the air. comp. Then when I revved the engine higher it sprayed ALOT of water. So it's definitely working.

If I'm running MAP vs. RPM, shouldn't it not spray until I have them BOTH at the settings I prescribed? Or is it supposed to spray when you have at least one of them? Because obviously the car was idling at 1000rpm or less, and I have water set to come on around 2000 or 2500 I think. And I think I have it coming on around 8psi or so, so obviously that was already reached by using 25psi. But I thought it wasn't supposed to spray until I had reached the proper psi AND RPM. Anyone have insight on this? Most likely anyone with this same kit, or at least knows something about it?
