Jimmer, The upper shrouds were on with these IC's before. My tech did the install last year and it was secure and fine, so I think the outside half will actually fit on without a problem. I will know more tonight.

Silvershark, The OEM plumbing is usually removed completely, but Todd has kept some in place. The EVO pipes are big and are jammed in there and I didn't want to go tugging on it and rip something else off in the process. I also wanted to experience this intake work before completely removing the Evo pipes. They can come out any time. So this was the easy way out for now. If I do an engine drop, which I will be doing this spring for a clutch...I will get them then and the mini air filter will go on the end of the oil tank vent hose. The oil vent hose can also be run to the air intake for an OEM application, if so inclined.

 

John, I would think the upper intercooler ducting would help a lot to direct air into the intercoolers IMO. I went with a longer, narrower air filter (K&N RU-1480) and cut out a small section of the duct to get fresh air to the intake.

 

Yeah, and I now see that Todd forgot to put a bungy cord on mine...

LOL!

Don, I think this would be better with the ducting in to gain as much cooling as possible, but would it not be best your filter was in the ducting also to gain max air flow?

 

You might want to ask Todd about it, it is in his stage 5 kit. They hold up my muffler bearings quite well

 

Just a rough, but like this, is it possible to work it around the frame?

 

I dont think that would work to well. The K&N would block the flow to the IC too much. It is quite narrow at that point in the ducting. A small cut out should get plenty of air to the space at speed w/o obstructing flow to the IC.

 

Don,

Thanks for the advice. I thought about doing the same thing and may do exactly what you did. When I asked Todd about it he said it worked fine without the upper ducting and that is how they do it. I have a feeling you would be hard pressd to feel the difference between the two methods.

 

I agree with Don - There is not a lot of room in there and it would directly block the flow to the intercooler surface if centered. As it is now, it hugs the inside and sits close to/against the inside wall, leaving the intercooler with unobstructed flow.

 

How do you get flow to your filter at moment Don?

 

Ah, sorry Don, got ya!, you cut a hole out the side of the duct.

 

Don, I did some test fitting this evening and I am going to go the same route as you did - I will be reinstalling the upper shrouds with a cut out on the inside piece providing an ample opening for plenty of air to flow around the filter. Looks like this turned into a 62 hour job :-)

 

John thank you very much for sharing your great work. Does your B6 intercoolers have bigger or smaller volume than those Proto's? Did you use factroy intercooler intake duct or B6's intercooler kit come with it. Did you drill a hole allowing intake pipe to go through your intake duct? Great job!

 

S4, The Protomotive IC's are larger than the B6's. I cut off the original Blown 6 connection fittings (1st picture below), which are made to accept the OEM clip on style coupler and then attached Protomotive aluminum intake plumbing (2nd picture below) in it's place. This was to keep the inside diameter of all piping consistent for the entire length of the run. As you can see in the first picture, the OEM fittings are restrictive at the connection points on the IC's. Silicon hose sleeves and T clamps are now used for the connection. This seems to be a better method as the connector does not have to be necked down inside and there is less chance of leaking boost. The hole through the body was slightly enlarged last year in order to get the hose to pass through from the IC, as the B6 IC's were different than stock and the hose needed a larger opening to pass through properly. This picture shows the enlarged hole and the way the OEM fittings become restrictive at the connector. The picture was taken before the IC's were sent out for the connector modification.




Here are the new connectors -

 

Wow! That is a lot of custom work you have done! Did you DIY? I'm about to get a similar setup like you. Hopefully, by the time I can find a skillful Porsche mechanic in Taiwan. Would you suggest me to get a pair of B6's IC or others because I would like to retain factory IC air duct?
