igor Posted August 9, 2005 Share Posted August 9, 2005 Hmmm.... Yeah... This is on R33 Gtst. I tried to rewire the bleed valve my car came with and hook up the stock solenoid as a fuel consuption experiment. I hooked up everything to the solenoid and went for a drive. There was no wastegate at all The boost just went through the roof. I tried swapping the hoses on the solenoid but to no avail. This is a diagram of how I did it. ___ | |-- | | --> to wastegate | |-- | | | | | | | |-- | | --> -------T-------- --> (cant remember) | |-- | | | | | | | --> (cant remember) | | |___| Where it says (cant remember) on the diagram: * One is where the bleed valve is hooked up at the moment * Another is blocked off at the moment. I am at work so I cant check any ideas straight away. Does this sound like the solenoid is gone? Makes sense to me. If the outlet is blocked off then the wastegate would get whatever pressure is in the hose (athmospheric most likely) and will keep boosting. Can I take it apart and fix it?

MANWHORE Posted August 10, 2005 Share Posted August 10, 2005 Mate, I don't know what you're trying to do, but i have a few pointers. The solenoid itself is quite restrictive, and does not let much air through. Also, I don't know if you've like hooked it up to power etc, but just try it. Get a bit of vaccuum hosing, and blow on it when the solenoid is open and closed to test it.

igor Posted August 10, 2005 Author Share Posted August 10, 2005 id just pick up anorher solinoid dude. <{POST_SNAPBACK}> Hence the sig I figured people should have trillions of them lying around after fitting aftermarket boost controllers. Blowing into it? Hmmm... I m not sure itll prove anything.

someonestolecc Posted August 11, 2005 Share Posted August 11, 2005 Blowing into the solenoid will test you've plugged it up the "right way" (i.e. for the air flow to be going the right way). Just blow into the side your intercooler/pressure is coming from and stick your finger over the hole going to your wastegate actuator. If you can't feel it then it's wrong and try the other way.

igor Posted August 11, 2005 Author Share Posted August 11, 2005 Ok, i ll try that. Link to comment https://www.sau.com.au/forums/topic/83551-is-the-boost-solenoid-dead/#findComment-1514374 Share on other sites More sharing options...
xRHETTx Posted August 11, 2005 Share Posted August 11, 2005 Yeah apply 12V to the solenoid and see if i clicks over, you will be able to hear it. Link to comment https://www.sau.com.au/forums/topic/83551-is-the-boost-solenoid-dead/#findComment-1514386 Share on other sites More sharing options...
igor Posted August 11, 2005 Author Share Posted August 11, 2005 Yeah apply 12V to the solenoid and see if i clicks over, you will be able to hear it. <{POST_SNAPBACK}> That will show whether or not the high/low boost works, but my wastegate stays closed at all times.

igor Posted August 24, 2005 Author Share Posted August 24, 2005 I had a "blow" into it and the thing is completely blocked. So I ask again, is it buggered?

The top fitting on the R33GTST solenoid is the input (boost supply), the bottom fitting is the output (to the wastegate). cheers Link to comment https://www.sau.com.au/forums/topic/83551-is-the-boost-solenoid-dead/#findComment-1541946 Share on other sites More sharing options...
