Title: 2.7T a6 throttle body hose issue Post by: em.Euro.R18 on September 09, 2014, 07:04:14 PM I know there are a lot of you 2.7t die-hard tuners on here. So maybe you guys have had this issue before. A co workers car can barely hold 14psi without its throttle Y pipe popping off the throttle side. Any tips or fixes? His hose is a upgraded silicone no name hose. I suggested a T bolt style clamp instead of a worm clamp but it seems like a tight place to get that in there. He's tryed hairspray.....

Title: Re: 2.7T a6 throttle body hose issue Post by: prj on December 04, 2015, 07:06:09 AM T-Bolt clamps are too wide. In fact, T-Bolt clamps should not be used on intakes period.
The force that it presses with is based on the area the clamp presses on. So if you have a clamp that is twice as wide, you have to tighten it twice as hard just to get the same clamping force ... You need a high quality narrow clamp that can be tightened properly. Either that or the Y hose is of bad design.

Title: Re: 2.7T a6 throttle body hose issue Post by: IamwhoIam on December 05, 2015, 04:58:15 AM Any decent quality clamp (Wurth and so on) will work there, there's no need for any t-bolt clamps ever.
