3rd gen 3sgte intake nightmare, Blowing couplings, do not have blow off valve and looking Options

[yarik83]

Hey ya guys. Its been almost 2 months since I picked up my celi from xat racing. They conveniently never put a blow off valve and I have had nothing but headaches since. Car runs like a beast and both my boost gauge and engine management system seem to do wonders with ocasional random things like my wipers going off without a reason for goot 5 minutes at a time with no means to stop it. Neverless I have gone through about 18 cilicone couplings so far, I even went to a muffler shop to completely redo my air intake so that it goes off straight from intake rather than straight and then sideways. A coupling lasts me about a week or less but it bursts pretty much daily. I know I need a blow off valve but I am so confused about it its not even funny. There are like cajillion blow off valves and most guys from here seem to have hks ones. Then there are universals, greddy and other fancy companies. Price ranges from 25-400. Obviously I do not want to overpay and or underpay and then regret it. I want to install a valve preferably on my own without going to yet another welding shop. I have seen some pipe things with flanges already attached but since I have 2 pipes one being on the car and one no longer used I am slightly hesitant to go that route because i would have to cut my intake pipe again. Yet the need for a solution is there and i cant be running to pep boys and home depot every other day.

I am looking for a blow off valve that works and not neccesarily name branded. I want it to perform like a trooper so that I dont have to worry about anything coming off when I am on a highway. I know that most of you here have hks valves and from photos they all look welded on. What would u recommend in my case? I have about 2 weeks time of not having to worry about it since my car is going into bodyshop for a major bodykit refitment and prep work so have this time to buy something and put it on as soon as my car is back.

Thanks for help.

To this day I have tried all of the following combinations. regular couplings sold in stores, 3 inch to 2.5 inch couplings (spectre) couplings used in diesel engines in trucks, pretty much every rubber and cilicone coupling offered at home depot for various uses. Ductape, reinforced couplings with metal coils and yada yada.

The couplers that you are buying locally are not made for boost. They are made to connect air intakes on an NA motor. You need to buy some 4 ply, high temp couplers. Not some plumbing stuff from home depot or something from the ricer section at pepboys.

I have tried to use as much as 4 clamps at a time holding things together and they are not powerful enough. I would like to think that 4 crappy clamps would make 2 decent clamps.

Not even close. Get t-bolts.

Ive had my intercooler setup for a long time now, and ive never had my piping blow off with proper 4ply couplers and tbolts.... and yes, Ive ran my car without a bov before.
