well i have the greedy type-s with the 1 spring taken out to recirculate in my car.....im having this problem where at idle it whitsles very loud.......every type of adjustment i try is the same thing it keeps leaking at idle......the diphram is good the lower oring is good.......every thing seems ok the only problem is the loud whistling sound coming out the air filter.....by the way i have the hks intake.....and when i put the stock valve back on the problems disapear and the car pulls harder...... and whistle goes away.....anyone have this problem any ideas on what to do ...oh and i lost the second spring so im screwed..........by the way the vaccum lines are fine and the second lower nipple is disconnected as recomended by greddy...??

 

Do you have any equipment to test it? even a $15 hand vacum pump might be all you need to find the problem. Sounds like your actuator chamber is leaking, did this just start happening all of a sudden?
Pull a vacum on the actuator, the valve should open around 13", the actuator should be able to hold vacum indefiniately.

Hope that helps,

Eric

 

well i have no access to a vaccum pump but by the way what and where is the actuator and what can be done if it is leaking????????????.......it has always done this since i first got it.....now the thing is that i can adjust it till it surges as soon as it hits boost.{which is a good sign cause that shows that the valve isnt leaking undder boost right???....but the thing is that it will still leak at idle....no mader the adjustment it will leak....so i can adjust it as much as i want hard or soft like it says on the valve ,it will still leak at idle ....but this is the weird part when i crank the a/c on idle the whistle gets worse.......i dont know if its has too much vaccum that it opens the valve at idle or if its a problem with the valve itself .....this is just a opinion i have but i doubt it..any ......any other opinions or ideas..i really need some feed back on this prob this thing is getting annoying....im not too good with bov's but i have a idea on how they work and mine doesnt look like its working right.....any one else with this problem???

 

Greddy recommends not hooking up the lower nipple? Usually the only people I've heard recommend that are people who don't know how to hook it up. The lower nipple gets a pre-throttle body pressure source. Only reason to disconnect it is when you go to the track, IF the bov starts to leak (which it shouldn't if you've tightened it enough).

It will give you bad compressor surge when properly adjusted if the lower nipple is not hooked up.

 

who said that about the lower nipple........and anyways where would it have to be T'd off to on the evo if you are correct........evrey other person ive seen runing a greddy on evrey type of turbo car leaves the lower nipple disconnected




Any ways can some one help me on my problem.??

 

well can some one else touch on the lower nipple subject its making me a little curious and confused..........can this be my problem .......not im more confused than when i started this thread lol

 

Hey, I think almost everybody on here who has the type-s with open air intake has the same exact problem. I posted the first post regarding this same problem. The leak is not bad, it's just annoying. My car pull hard and it kinda stop leaking after I drove it. Well, hopefully it doesnt leak under boost. The whistling sound is not so bad.

 

oh, sorry if i don't really know a lot, but is there a difference between just a regular intake? and an open air intake?
