quieting down a bypass valve

[DSG2003Mach1]

checking to see what price we can get on our corporate account at two distributors before going to ebay. Ordering the coupler now though

@blazen71 Im assuming the 2.35" end goes on the BRRV - thoughts on a 2.5" working? the elbow you linked is $19 but either $20 or $30 shipping... I see plenty of 2-2.5" ones.

Same thought.

Can I get in on the corporate pricing?

Are you guys trying to pinch pennies on a car you've spent thousands and thousands on?

I'll let ya know what it is, sometimes it's good and sometimes it isn't

Are you guys trying to pinch pennies on a car you've spent thousands and thousands on?

absolutely. I've saved a lot buying stuff used, buying it on sale etc... $20 for shipping to get it in a month or $20 to get it in two weeks - that just rubs me the wrong way. If I can buy the muffler at decent price through our rep and just go pick it up local I like that option if the cost is similar.

Good luck. I've done all i can do for you.

oh dont get me wrong, i definitely appreciate it. Im gonna look through my box o junk at home, I may have a 2.5" silicone connector laying around I can check for fitment on the brrv outlet.

Why spend 20$ on shipping when I have Amazon prime and could get it free?

I had no intent on changing my setup but now I'm looking into recirculating bypass valves to replace my 50mm Tial Q series. Thanks.....

i will definitely do some before/ after videos on this once I get it set up.

Here is an eBay link for the first one I used. It is quieter but flows less. If you have a small S/C pulley running a lot of boost this may not be the one for you.

I purchased the other one you posted. Thanks for posting this one.

Have you found anything that fits the Tial flange and has a recirc outlet? I swapped to a Tial QR and it caused compressor surge. The outlet is way too small.

 

[blazen71]

I searched in the past and couldn't find anything? You'll prob have to bite the bullet and get a BPV with a 2" outlet like a Vortech Mondo or Procharger Big Red Race and weld on the appropriate flange.

Turbosmart makes one but they are proud of it, Big Bubba BPV 'By-Pass Valve' BOV (Sleeper)

Edit: Just saw Turbosmart released a recirculation version of the raceport this year too. GenV RacePort Plumback Valve (Sleeper) Female Suit Supercharger

Tial also has the QRJ which doesn't flow as much as the Q series but quite a bit more than the QR.

The Big Bubba Sleeper is pretty slick. If that would have been available at the time I bought my Procharger BPV I prob would have got the Bubba instead. Speaking of Turbosmart, if anyone wants to make a pre and post muffler BOV setup like I did, their BOV controller is the quality version of my cheap $50 eBay controller. The controller I have is the China copy. The ebay version has a rheostat for TPS sensitivity only. The Turbosmart has a rheostat for TPS sensitivity and activation duration. And again, if I would have known this was available I would have got this one instead of the Ebay China version. Oh well, my setup works great, (for now).

Here is a video of the secondary BOV function. I throttled down slower a few times to show that it stays shut during normal driving. Every time it opens I'm completely letting off the throttle.

this one fits for $20 and free shipping on amazon - the 2" - 2.5". The narrow side is tight fit on the BRRV outlet, I sprayed some foaming window cleaner in there to help slide it on and then on the outside to get the clamp to slide over. The clamp is a tight fit, either take the nut completely off and put it on or back it off halfway (only threaded half way into the nut) and you can get it slide up.



I'll swap valves around here in the next couple days and see how it sounds, that muffler is definitely much heavier than I was expecting. Im wondering if it'll start flopping around a bit after some heat cycles on the silicone elbow so probably try to zip tie it something just to be on the safe side

If you look at my pics I used a fuel pump mounting bracket like this. I bolted it the wheel well liner
