Here are pics of the BOV I'm selling. I'll have pics of mine mounted on the lower charge pipe later. Enjoy.





Not crushed.
Just your average 88 GP with a 2800 hybrid, Getrag 282 and GT3271.

Who wants a quiet BOV.. the louder the better! :icon_cool: lol
I want a quiet BOV stealth is good. I use to have a 440 challenger years ago and didn't have the cash to get a rear panel with the cut outs for the factory chrome tip dual exhaust. So I found in an exhaust book a dual set up for a big block with turn down pipes. The passenger side was the same pipe the 318 engine with single exhaust would have used. So when I put it on I hung the drivers side up real high so you couldn't see it when you pulled up behind me. Many people pulled up thinking single exhaust must be a 318. Just to find out they got beat by a 440. I don't like advertising I have a turbo car. I even have a plain jane 3 inch turn down exhaust pipe on the end of my 3 inch exhaust. I don't have a muffler on it but may some day. It really isn't too load. The exhaust did make the turbo spool sound a litle louder. remember stealth is good.

Yeah, I bought a stock plain Jane 67 mustang fastback with a 289 with the 289 emblems on it, dropped a built up 428 Cobra Jet motor in it and a 4:11 gear, made a lot of money street racing until people caught on.

So, I know I can use any manifold vaccum line, with the exception of the FPR, but what line is everyone else using?

Use the one coming from the MAP sensor on the back of your upper intake manifold.

It just occured to me that I could run the line from the empty space where the EGR line used to be...anyone disagree?

Because I'm running a 5 speed, I've got mine hooked up to the line coming off the Throttle body for the tranny vacuum modulator.  However I know Matt(93luminz34) has it hooked up to the back of the plenum where the main vacuum line for a NA car's brakes run to the brake booster.

As long as the source of the vacuum line comes from the engine side of the throttle body.

Ditto, I have mine hooked up to the trans modulator port on the plenum.

Josh (Turbosedan) I think just taped a barb fitting into the port for the EGR and ran his from there.
