Like Jordan or Jay-Z, it seems like I can't retire for good from modding. Every time I try to get out, it pulls me back in!

Working on a new project.. this one will be BIG. Anyone want to guess what this goes too?

Here is a hint: CNC machined, billet aluminum...

 

Cup holder!

 

5.0?

 

Seriously though, looks like an intercooler hose adapter.

 

I think Tim is right! If true I've been waiting for this mod for a very long while. Please tell me you will be making more than one?????

 

I'm sure it will be awesome...whatever it is!!

 

What I was thinking. The bump and 0-ring did it for me. Will this lead to larger hoses and bigger turbos?

 

Hmmm, trying to get ever closer to having the 1st 1,000hp Cayenne?? Can't wait to see how it goes!!!

 

Haha... I know...

 

larger intercooler adapters?

 

Bong?

 

Whatever it is Im in.

 

Please make extra

 

to fix the coolant leak issue??

 

Ah man.. you guys are too good! I would have thought only a handful of guys would have recognized what this is...

It is a Henn coupler (adapter). Henn as in "HENN GmbH & Co KG", an Austrian company that makes quick disconnect couplers for coolant and boost applications. Porsche uses their couplings for many connection points across the Porsche lineup:



Here is the OEM Henn coupling that goes from the turbocharger outlets and into the intercooler lower boost hose:



The problem with the factory lower boost hose (besides the expanding rubber hose itself) is that their are several step downs inside the factory metal adapter. This is so it can properly crimp with the rubber hose, however, it unneccessarily restricts flow.

Here is a close up of the internal step downs:



The smallest diameter is step is approx 31mm:



However, by using a custom Hanns coupling adapter made of billet aluminum, we do not need this step downs and can increase the internal diameter quite a bit to approx 41mm:



That is about a 30% increase in diameter and flow for both turbos! Just means more power
