Hey all I have some concerns about raising boost pressure with the worm style clamps that come with the Greddy TT kit. I'm wondering at what pressure these clamps will start to blow pipes off? I have t-bolt clamps on most of the couplers which isn't my concern. The couplers on the turbo outlet pipes are a mother ****** to get to and I have not changed them to t-bolts yet. Anyone have issues with the worm style clamps blowing off at 15-20 psi?

 

Also all the pipes are bead rolled.

 

if 15-20 is a problem, I'd be looking more at your piping and your couplers. worm clamps can be very good. if you look at norma clamps and properly tension them 20 psi would be no issue

 

^I'd hit your intake charge pipes with some sand paper to increase friction between the coupler and the intake pipe ... I doubt you'll have issues...

 

Depends on the worm clamps. I've seen many crappy ones and a few good ones. I switched all of the t-bolts in my AAM kit out for BREEZE brand worm clamps. We've been using these on many cars, we boost leak test every one, and they've been holding 32 psi just fine. They fit into tighter places and are easier to work on when you're pulling stuff on and off to fix things. I had zero boost leaks on these all three times I've put the piping together to do engine swaps (built, back to oem, then back to built, don't ask).

 

Ok thanx for the piece of mind guys. I feel better about it now. I have just been putting off changing the clamps on the turbo outlets cause they are such a pain to get to and was a little worried about blowing a pipe off on the dyno. But as long as the pipes are bead rolled and they are I think I will be ok.
