Silicon on the intake, collapse in?

I want to use silicon on the intake, question is, with a stage 3 do you think I'd have trouble with it collapsing in at all? Supposedly a problem with the K&N intakes.

The whole thing won't be silicon this is what I'm going to do:

3" intake

With a 3" silicon elbow to hook up to the turbo from Ebay.

 

i know that the silicon lines i have run in my lab that were hooked to 21 inches of vacuum collapsed badly!!! if the material is not reinforced somehow within in the walls of the tubing, then i would be conerned, even with lower vacuum levels being pulled, such as inside an intake......

 

the K&N intakes are the worse the mopar,jbm,ED,AEM are all good ones

I would think it would collapse...I mean the car still hits 30 PSI of vaccuum, right...30 PSI is a lot.

 

no they dont its not measured in psi

 

:sorry: not PSI...inches of mercury, but it's still strong enough to collapse unreinforced silicone.

 

anything greater than 3ply silicon will not collapse. my entire short ram is silicon and it holds up fine against the 3147

 

I have the K&N CAI but running it as a SRI. The elbow on the K&N unit is a concern but there is a fix to it in which I wrote a how-to on it.
