hehe... ok I'm the idiot now.

The metal piece that come up from the turbo compressor housing towards the intercooler has two holes protruding out of it. The larger one goes to the Air Bypass Valve... what is the other smaller one for? can't see it in the FSM. Also didn't take photos from the right angle of my engine bay. Anyone have a quick answer here?

 

one hole for your BOV and the other goes to the BAC valve

 

ok... so that is where the BAC gets the extra (filtered) air to add to steady idle?

My BAC is dead and gone and blocked off so I guess I will block off that hole too.

Thanks!

 

Since the hole is protruding from the metal pipe coming right off the compressor housing, what should I block it off with?

I'm thinking it is going to be under a lot of pressure and heat so a rubber cork isn't going to work. I 'could' use a big glob of JB(dc) Weld but it would be a huge pain to hook up the BAC again if I ever feel the need to.

Ideas anyone?

This is the last thing I need to get my car running tonight with my new mandrel 3" TID... I'm so excited I can barely contain myself. The car hasn't been on the road since the end of November. Crappy winter.

 

I want to get my car on the road tonight if possible... come on, someone with NO BAC -- what did you use to block off the protrusion on the pipe between turbo and intercooler that went to the BAC? I need to know how much pressure it's going to be under constantly and how hot etc... someone without a BAC had to have done this.

 

Uh, knowing me, I would just JB-Weld it. Apply some tape to the inside of the piece (to keep it smooth inside) and glob a bunch of the JB inside. If you ever "MUST" have the BAC again, you can just drill it back out.

Auto parts stores sell vacuum line nipple caps. Put the little cap on, and use a zip tie to hold it tight.

 

well this is a fair bit fatter than a vacuum hose and the heat it is going to have to withstand is going to be really high I'm thinking. Would one of those rubber/plastic caps melt?

I've never tried drilling jbweld but I'm thinking I'd need a new metal pipe altogether once I fill that sucker in. Oh well I should be going FMIC in a year or two so that pipe would no longer be needed.

 

I just JB welded a big rubber stopper in there, like the ones for test tubes. LOL

 

I just had me a good ide-ar. Huh-hyuk!

Go to Home Depot and get a big bolt that will fill up the hose that used to go over the nipple. Stick the bolt in the hold (hee-hee) and clamp it down. Problem solved!

Sounds like the best idea yet if I can find that crappy hose. Probably not good for airflow though. I'll probably jbweld that sucker up anyway because I like the idea of smoothing that hole over on the inside.

Thanks for all the ideas guys!
