Heyy guys well this last weekend I installed a Apexi AVCR and TBE..Now whenever I start to boost numerous times my upper inntercooler pipe blows off from the bend rite after the 90 from the throttle body. I dont know, mayb i installed it wrong but this is really weird the most I have seen was about 1.4 bar. The a pop and the car goes dead. I realy dont know what else it could be. I went to Lowes today and bought a new clamp, tightened it down tight and still a pop after a little while and the car dies...Anyone know what this problem can be caused from.

 

A T-Bolt clamp willstop it from moving. try and tighten your clamp before the "lip" to keep it from moving. if it still pops off, t-bolt clamp that sucker

 

where can i get one?

 

You can buy a t-bolt clamp at your local Napa Autoparts. Check out this link in the sticky above:

so im taking it that these are better then the one i bought at lowes

 

Absolutely

 

Does the end of your pipe at that connection have any sort of lip? If not you're gonna have a tough time keeping it from popping off and/or leaking. Ideally you'd have a lip... you could go ghetto and get some vice grips and bend your own, though could be messy if you're not careful and not all that nice. You could take it somewhere and have them weld a bead around the pipe. You could have someone use a bead... maker (forget the name of that tool/machine) to create a really nice ribbed end to the pipe. Lastly, if you're a lazy *** like me or want to get by until you can get something welded is you could create a bead by layering up some jb weld.

One way to do this is to layer up two rows of tape near the edge of the pipe so as to create a channel. Just fill the channel with jb weld and let set. You may need to do this a few times. Yes it's ghetto, but it'll work.

If uh you have a bead/lip on your pipe you can just move along and disregard my entire post and go buy yourself a better hoseclamp You can always add a second hoseclamp if your connector gives you that much room.

 

Just to give you an idea about the difference in clamps....your standard clamp you bought at lowes will allow you to tighten it to about 35 in-lbs (maybe). T-bolt clamps will allow you to tighen them to around 80 in-lbs. This info is pulled from the grand daddy of all hardware stores www.mcmaster.com

take a look at catalog page 240 (your lowes clamp) and page 242 (t-bolt clamp)

Make sure you measure and get the right size....

measure the circumference (of the coupler) and use the following equation to get the diameter

C=pi*d

Thought the post could use some actual data. Good luck.

 

Same thing happened to me when i got my evo. It was so annoying. The clamps werent heat conductable, so whenever the engine got hot it loosened and came apart. I just went to the local mitsubishi dealership and got some new clamps. 2 years later and hasnt happened since.

 

Something to note about t-bolts. If your piping isn't very thick they can give you the ability to bend your piping. I found that out the hard way on custom pipes I have on my Eclipse (I was cheap on the material hehe). Was wondering why I was able to just keep on tightening that t-bolt haha If you're just mindful of how much you're cranking down on them it's not a problem (never happened on other connections for me, just one where I was a bit overzealous).

 

Lower your boost, if your blowing the hose off the TB your probably over boosting. Make sure your boost gauge is connected to the manifold so your seeing what the car is seeing. Also make sure not to use any factory T's in your boost gauge connection, many of the factory lines contain restrictors including the factory boost gauge line and you will not see the boost spike.

 

its not a factory boost guage....

 

The above mentioned T-bolt clamp solution is your best bet and make sure the clamp is all the way over the bead. If you set the clamp even partially on the bead it won't do you any good. T-bolts can easily crush aluminum as also mentioned so be cautious when tightening them.

My Car did this STOCK, T-Bolts fix it perfectly
