well lesson is, pressure test the IC's yourself even if they are secans.

Heck, all I did was put the shop vac on one end with a rag to seal it and my hand on the other end and I could clearly hear the noise of air wooshing out of the IC through the cores.

 

what brand are these things?

 

Hey Dennis this is not a JK any more,sorry for your project.

 

Whats the likely hood that the stock factory units suffer from the same leakage issues?

 

good question. I have a spare set, I can check. I also have a set of GT2's I can check. Earl can check his knew ones as well.

 

chances are - they leak. tabs that hold the end tanks on tend to loosen a bit under higher boost and create leaks. i have not tested mine - but my friend with a Leagcy GT which has a top mount intercooler with plastic end tanks like ours had isses with the stock unit leaking at higher boost.

 

I've checked the new ones (997.2) and my old GT2/997.1 cores when they went on. At just over 25 psi, they held steady for 5 minutes, at which point I released the pressure. In both instances the cores were lightly used (<500 miles) before I got them. Even though I haven't had issues, I always pressure check from the turbos whenever I mess with stuff in that area. Particularly important as these cars have some age on them now.
