    Default need help finding a 3way air valve that's electric for a experiment

    i need a 3way way air pressure valve that i can just turn a switch or hit a button and go from 1 pressure source to another. got an idea for a slick set-up for turbo motors and i wanted to build it and try it out, see wtf it'll do. basically i'm looking to be able to smash a nos button on the wheel and go from a low boost setting to a high boost setting, but need the valve to make it happen, already figured out how to plumb it. any ideas out there? we're using 1/4 air line(the pvc black type). thought maybe there was a valve for airbags that might work but i'm not finding anything.

    Dare to be different, if it turns out great you can claim you planned it that way.

    Tom, Norgren makes valves like your talking about! 12-24-120 volt ETC. Their site is www.norgren.com hope this helps! More in the industrial line but I bet they will work in your App. WT Coby

    found a 2 position pedal that might work too go pedalllllll would be simplier , no electrics



    no solenoids to burn out and he could just smash the pedal when he wanted all the boost

    Sounds like a really easy setup to build. I'd plumb the wastegate like normal and put a solenoid on the wastegate line. All you'd have to do is experiment with jet sizes or a needle valve adjustment to have a controlled bleed.
    That would be pretty much the same setup the Buick Grand Nationals came with so the ECM could control boost. The only difference is that instead of using a PWM signal to bleed off signal you'd be using a metered dump for a specific boost.
    That setup would open the door for off the shelf boost controllers so you could scale back boost or increase it for whatever reason.

    I think I have on in my junk box. (it is not junk, I just don't use it). I will send it to you. You pay the shipppng.
    I am leaving for a race tomorrow am, so Monday is as early as I could ship it. If interested PM me, or e-mail me [email protected]

    saw those, that same company sell the air piloted style of the same valves. trying to stay away from c02 though. been pricing the nice controllers and 400-500 bucks plus having to run c02 is just too damn complicated to be on a boat. we need a high setting and low setting, that's it.

    actually if you're using real air pressure regulators and then running 1 to each side of the valve, you could adjust each regulator to hold a psi level, then switch between the 2. real regulators will bleed off as you mentioned. pretty simple concept, should be cheap to build as well. we've gotta race coming up in sept we realllllllly wanna win or at least make it to the finals. trying to make it so when he leaves the rope he can do it on the low boost level, and when its go time, switch to the other air pressure regulator and slam the gates shut should work out pretty wicked, be like hitting a 700-800hp shot of nitrous

    A friend of mine ran a Banks TT set-up on his '82 street Trans-Am. He had a micro-switch on the Nos system with a boost reference. The Nos kicked off at 7psi. That was a fun car to drive I'm lucky I never hurt the engine when I was behind the wheel.

    we had a 125 plate under the blow thru carb for nitrous enriched with methanol but after knowing how fast it spools, we took it off, its not needed.intake almost freezes during boost anyways.

    You shouldn't "bleed off" pressure because that will require a change of the jet size with the changing of the amount of boost. The way we have done this is with a check valve and solenoid to apply boost to the vent port on the wastegate with an adjustable regulator. If the wastegate spring is 10 lbs, and you apply 5 lbs. to the vent port, the wastegate will now operate at 15 lbs. An adjustable regulator alone at the drivers seat allows changes on the fly. The three way solenoid and regulator allows instant changes with a pushbutton. Been doing it that way for 35 years on boats, sandrails, and street/strip cars and it is the best way we have found.
