I was looking at my car today and couldn't help but wonder if anyone makes a slightly flared out intercoller duct to replace the stock unit in the rear fender. Theoreticaly this might channel more air through the intercoolers?

Nothing drastic, maybe just a smooth 1" protrusion from the body.

Thoughts?

 

There are a couple of companies that make them. The one that comes to mind first is Kokelen?

 

Kokeln makes such a product:

I have declined to purchase one for fear that the adverse affect it would have on aerodynamics would overshadow the benefit of the additional air directed at the intercoolers (note that Kokeln incorrectly claims that its scoop supplies greater air to the airbox).

manthey racing makes one as well.

 

Wow ive never seen or even thought about this, looks pretty cool though, but its just for looks lol!

 

looks like got BIG EARS.

 

Manthey racing never do anything for looks.

 

I'm impressed at your depth of knowlege as usual Craig.

This product seems like real winner to me. Especially if you track your car. Nothing like improving cooling capacities on stressed components. WE all know that Porsche overengineers its components. Our cars are designed to run at 100% for 24 hours at a time. Still, running 1.2 bar IS increasing boost by 50%.

I don't think it would do anything for me given my 10 minute commute to and from work with few a blasts thrown in for good measure. Hell, I have yet to go for a sunday canyon run in my car.

Do you really think this will affect your aerodynamics? My understanding is that most aero stuff have little effect until well beyond 100MPH.

 

I like the Manthey unit . . . does anyone sell it locally?

 

I know that it's made out of carbon and very expensive. One of the sponsors here is a Manthey dealer. Hope he checks in.

 

So how do you assume it is better for cooling, because overall its an inch larger and grabbing more air in?!? I doubt it lol!

 

Well they say the temperature of air will be decreased 5-10 degrees (celsius).

Costs 1040EUR in Europe. Made of carbon.

Manthey is a nice company, although a bit expensive (imagine that you've just done much laps and you need new brakepads, tires etc. or a nice suspension tuning ) The place is absolutely worth checking out when being at the Nürburgring...

 

I don't think it is very functional. I remember reading that the stock system works off negative pressure....so "scooping" more air doesn't do anything really.

 

I don't know if these particular set ups work or not but 2 things I got for sure, Manthley wouldn't sell it as a performance item if it wasn't and that the fact that by working by negative pressure generated by the air going by the air outlets (on the bumpers) does not mean it wouldn't benefit from positive pressure being generated on the other end, actually it would help create a stronger flow.

 

Hmm i understand they wouldnt sell something without function, but still, i find it very hard to believe it can decrease temp. by grabbing more in, maybe cooling the engine that degrees?!?
