Please don't flame me, as I DON'T plan on doing this, but I was just wondering if JB weld would hold up on the outside of a compressor housing?

For what,......to put a nipple on it? I have my vac nipple JB welded on the pipe right off my compressor housing for the Profec B........no problems.

Really? So it hasn't melted or cracked, or anything?

Last time I used JB weld on somthing that got semi-hot (throttle body), after about a week the JB weld tured into somthing that felt simalar to rubber. I bet the compressor housing gets hoter than a throttle body too...

That's what my thinking is...
I'd like to here other people's experience/knowledge though

I've used jb weld on a deltagate wastegate when a part of it cracked off where the vaccum fitting on the side goes. I put like on three coats of it on and it's still holding, for about a year now. Of course I would never use that wastegate on my car, it was used for a friend who wanted a super cheap turbo setup. jb weld

i used it on the top of my radiator when the mount stud snapped off. (metal to metal). used JB and its held ever since. make sure you scuff the surface, and mix it 50/50 perfectly. also stir it really good. although no guarantees on a turbo....does the package say the temp limits?

yea i just installed a profec b on my civic. used jb weld to hold the nipple in the intake pipe; i mixed it well and put the pipe under a heat lamp for 3 hours and it's now hard as a rock. i'm not sure if you should use it on a turbo. my friend's friend used it to hold a bov flange and it fell off cuz it got too hot. but then again i don't know if he cured it properly either.

hmm... good stories, sounds like JB weld's got a pretty good track record. The package says it's good to 600 degreee F

I used it as a temporaory solution on my oil return fitting (on the pan) and for my bov flange and neither lasted very long. They cracked and fell off. Then again, I had an old Dodge with a 225 slant six that had a crack along the water jacket all the way down the block. JB Welded that bitch and it ran forever, never leaked or had problems after that.

for vac nipples i thinks its ok, but my friend used on his exhust for a quick fix on a n/a hybrid and it melted off and dripped all over the garage floor

i dont think it would work on the housing...ultra high temperature there...maybe give it a shot?? but i dont think it will hold up against that heat

JB weld works excellent, but the MOST important thing you have to watch is the surface. JB weld actually soaks up oil if you try it on an oilpan or something like that. Make sure to CLEAN and dry the surface before application, and you'll never have a problem with it clipping or flaking.

Tell me this, how hot does the compressor housing get????

Just thought I'd share my JB weld is the **** story:

If you've ever visited my profile you will notice that i have a link to page dedicated to my daily driver. Its an old chevy pickup. A few years ago before it was restored to the present condition I pulled into a gas station and the attendant said "hey your leaking something." wonderful my radiator had sprung a few pin hole leaks toward the bottom. So i go across the street to pep boys and get some JB weld. mix it up with a little stick and spread it on the radiator over the leaks. give it like 30 min to set up, refill the radiator and it has been good to go ever since. I have also used JB weld to fix a crack in a block to a coolant passage and that has lasted for about 6 years so far.

I would say as long as it is mixed and applied correctly it will hold up as long as anything else besides actual welding.
