I would rather not name the vendor/manufacturer until he has been notified because he has been such a great forum supporter and a heck of a nice guy... But this is a heads up for eveyone who is running a silicone, wire-reinforced turbo inlet pipe -- go out and verify yours has not split where the wire reinforcement starts. Since I installed mine behind the stock airbox (with Cosworth Drop In) I had noticed some midrange stumbling and loss of power. I assumed it was simply my imagination or bad gas or...? Afterwards I noticed a slightly rougher idle and this high-pitched "squeeee" noise under boost. What had been happening was that the inlet was unbelievably collapsing under boost so much that the support wire tore through the silicone. I have a slight tear with the sharp end of wire poking through on the underside of the pipe about 4" behind the Maf. This is just a heads up for you folks to go and check yours. BTW, I'm running stock boost.

 

Did you happen to over tighten the clamps to cause the inlet to collapse? Did you buy this inlet new or used?

 

I bought it new. On this particular inlet, the wire reinforcement does not travel the entire length of the inlet. It starts about 3"-4" behind the Maf end and ends about 3" from the turbo inlet. The tear was 3"from behind the hose clamp at the Maf junction. The tear started right at tbe beginning of the wire. I. E. the tear was not close to any clamp and was not caused by any clamping. The silicone deformed under boost; the wire did not and thus tore through the silicone.

 

Damn most likely defective inlet. Get a replacement through warranty.

 

Was this a Depo pipe?

 

I guess he will let us know when the seller from this forum either warranties it or denies it.

He is trying not to put the vendor on the spotlight , although he kinda did by starting the thread about it , because now I am curious to know who's it is either way lol.

 

Its not cobb or perrin by the way... use process of elimination.

 

alright, so not being cobb or perrin, im good since i have the cobb.

 

I've run both the Cobb and Perrin and both of these are very high quality with no issues. I would say Cobb's possibly has stronger reinforcement, but that's just my opinion after owning both.

 

This has happened with most sillicone inlet tubes that i have seen for the evo X. Save the headache and just buy a metal (SS or Al) inlet pipe.

edit:

Here is a log of an inlet pipe collapsing.

 

I believe the above post with the graphs represents the collapse of AEM's pipe, which, BTW is not reinforced, made of plasticised rubber that weakens under temp and load and suffers from a filter placement located too close to the edges of the intake box. This is a known issue with that intake.

As for my inlet, a pm to the manufacturer had been sent out 48 hrs ago with no reply. I'm not wanting a warranty replacement. I firmly believe the failure of my inlet pipe had to do with the silicone not being fully cured (removed too early from the jig) and the wire reinforcement just started at a place where the silicone was very weak. I don't believe it is an inferior design and I think my issue does not represent the the quality of the item as a whole. Ultimately, only about 1/8" of wire is exposed, but the hole underneath is smaller. Also, one of the above posts mentions the make of the inlet... I'm replacing it with a Cobb.

 

dang and i have the samco

 

I removed the inlet yesterday and the hole was smaller than I thought, but a hole none the less. It failed right where the support wire begins. I replaced it with the Cobb. Special thanks to Cobb and Forged Performance overnighting my "custom" no logo inlet. The Cobb is VASTLY more sturdy. Lesson learned...
