Lookin to see some designs for a 35r boost tester. I need something to fit on the compressor housing and stay there. My current PVC boot doesn't seem to hold very well. Pops off after 18 lbs or so. Anyone got a good working tester?

 

You really shouldn't need anything more than what you already have, as that much pressure isn't necessary for locating leaks. If there are any leaks, you'll hear them well before you get to 18 psi.

 

you think? With my stocker I would test up to 24 lbs to be sure everything would be fine at 22-23. I figured if your gonna test it, test it at least to the pressure it'll be running at, no?

 

Well, you can if you really want to, but I've found it (so far) not to reveal anything that didn't make itself known at less pressure. Likewise, that factory intake tubing isn't really intended for being pressurized.

 

I didn't use the tubing. I had the stock turbo with my AEM and a fabbed intake.


This is what I used, it went right on the compressor housing. I have the same thing now that I'm using for the 35r but bigger.

 

I like the ball valve on that one! I think I'll incorporate that into my next tester, thanks I've found that it pays to build the tester using regular couplers, like you use on your IC piping, and t bolt clamps. I never have any problems with the tester staying on. Those hardware/home improvement store Fernco couplers are way too soft. The trick is going to be finding a combination of reducing coupler ($) and cap that will work, but a little creativity and experimentation will get it done. Ideally you could find some kind of cap, or something else that can be used in the same fashion, that has a 4" OD so you can stick to the cheaper straight sections of coupler.

 

http://boostpro.net/prodtester.html You can try that, from my experience with my 2g dsm, the fernco couplers are junk. I was in the same boat as you, the coupler would pop off at 18psi or so . I am not sure how well this will work for you well either, due to no lip or anything to clamp against to keep the coupler from popping off. Good luck either way.

 

Doing it this way gives a bit more flexibility and full pressure control:
