Custom Purge Setup

[nkhende]

I'm making a custom set-up on my car, and I could use some experience in helping me make it out of stuff I have. I know what I want to do, I'm just not sure of the best way to do it. I need something that will act as a switch tripped by sudden vaccuum, like the pressure that trips the BOV, (I was thinking of using my unused boost control solenoid, or one of the other useless solenoids), and the best way to use that completed circuit to spray(I was thinking an old working fuel injector). I want to be able to adjust the amount shot, and the time it's open. Any ideas? I'm not expecting any gains out of this, just have a cool idea that I think I can put together from unused parts I have.

NOS has adjustable pressure switches. http://www.holley.com/types.asp?type=193
Here is the installation manual. http://www.holley.com/data/Products/Technical/A5100-SNOS.pdf

I wouldnt mess w/ it. Just stick with a wide open throttle switch. The simpler it is, the less problems.
