Got a little odd of a question, does anyone know where I can get a electrical switch that I could hook to a vac source so once I hit 1 psi the switch would flip on and after I exit boost the switch would turn off. I fuigered that I could probally make one... some how. But I am lazy and was just curious to know if anyone herd of such a monster.

i may be mistaking but that sounds a lot like the boost switch that turns on my water injector

when i hit a preset level of boost (changable on the switch itself)
it turns on the relay which powers my pump

i got it from the cooling mist webpage
hope this helps

i am 4000 miles away from my car or i would go look at it for you

Thanks a bunch. :thumbsup

Look for a "Hobbs Switch".

What do you want the switch to do?
