New solution to Blowing Couplers
 
3 Attachment(s)
Ok so im ------- around in the garage, and this hit me.

What you need, is

Standard 3 or 4 ply coupler
Home depot style clamps... bar and plate work, but the point is now you don’t need them ;)
Electrical tape

What ya do is place the coupler on the pipe, and wrap it with the electrical tape. I went around the coupler 20 times..
Attachment 17572

Then ya put the crappy clamp on and it holds great..
Attachment 17573
Attachment 17574

I tested it on a smooth piece of aluminum charge pipe i had left over... The tape by it self held good to 40psi, and at 60 started to slide, and eventually blew off..

I haven’t tested what the holding pressure is with the clamp on yet, ill get to that latter tonight.

The whole reason i started trying it was, because my bar and plate clamps always got maxed out before it was really tight, so i out some electrical tape around it to make the circumference bigger...

It holds good to 40psi, with just the tape, and held 65psi for over a minute with the clamp and held 80psi, for10 seconds......not to many of ya if any are boosting over that... so give it a try..

try it again in a hot ass engine bay with heated charge air and the fucker will give in at a way lower psi reading

yea welding works good, but i cant weld aluminum, and its what i had in the garage, i welded from the turbo to the ic, but the other side is all aluminum...

and if i get a chance ill test it while the torch is on the pipe and see what it holds

This is exactly what I was thinking. Adhesive tends to get soft and gooey when it is hot and will actually cause an area of slipping for ya.

Not to mention cleaning after the heat gets to it and you have to weld the pipes

Electrical tape sucks... should've just made a bead of JB weld.

i used to find a way to zip tie ---- when i had my ghetto setup. I had PVC 90* elbows (---- anyone who says they melt, they lasted 35K miles on a D @ 10#'s) and i forgot how i did it but i'd ziptie everything to everything and it worked :P

Re: New solution to Blowing Couplers
 
just flare the end of the piping, or cut slits in the end of the pipe all the way around and bend it a little bit up. Welding a bead is a much better way

poor mans welding = http://search.harborfreight.com/cpis...=pipe+expander + couplers

they got em for alot cheaper.. there are the non screw ones which is basically a cone shape that you hammer into the pipe.. ittl expand one end of the pipe so you can jam the other end of the piping into it.. if i were to do it id expand both ends of the piping and cut a 3rd piece of piping to go inside both of them and the couples would never come offf at all

no tape on the pipe, just the coupler...

I just noticed that it made the standard clamps hold better.... Not comparing to welding...but in my case, my welds all have pin hole leaks.. took an hour to re weld everything today to try and eliminate the bigger leaks..

you could just buy the right size clamps from me. i have never had a properly sized t-bolt come off

i've tried tape before doens't work for long. once it gets hot the tape slips off

Re: New solution to Blowing Couplers
 
why cant you just... i mean... i dont know. flare the ends?

have you ever seen warm/hot electrical tape? you fail :X

grey rtv silicone around the pipe and then ur coupler and clamp. seen that done and that seems to work pretty good.

Re: New solution to Blowing Couplers
 
Drill a 1/4" hole on either side of the coupler in the piping. Put a bolt and washer in the hole from the inside out and tighten it up with some High temp RTV for sealant. Cut some aluminum flat-bar to a little over the distance of the bolts, and pop two holes in it to match the bolts. Bolt it to the new "studs", and it's never coming off. Or just weld aluminum studs on.
