Intercooler concerns
Hello folks, just this afternoon my nephew stopped over to have a look at my 993 TT.
As far as the Protomotive IC is concerned, he was disappointed to say the least. He runs a big single turbo Supra himself and builds crazy power. He was saying that the end tank design were terrible and that it appears as the intake piping was cobbled together. He pointed out as well that the inlet piping on either side goes through a bottle neck. As the pipe goes from a larger diameter to a smaller diameter and then flares out again it slows the flow of air.
Now neither of us are Porsche mechanics at all, but it has me thinking. Should I just put my stock IC back on? He had some good points in regards to inefficiency. Possibly it is more efficient than it appears? What do you think of it?

I think you test it, measure your intake temperatures under boost and load and see what is actually happening.....
You can't really tell from just looking at an intercooler if it actually works or not and Protomotive are as good as it gets for Porsche turbo tuning in the US

Arghhhh! Posts like these infuriate me!
There is absolutely NOTHING wrong with that Protomotive intercooler..in fact it is absolutely beautiful...look at the length of that pipe it is SHORT...it is not harming air flow, velocity or flow. You would be unwise to put back your stock unit (I am refraining from using the word "foolish") back on the car.
On a 911..the extremely limited engine bay (read "SMALL) dictates the intercooler size, location and the plumbing location. Protomotive are extremely reputable, I would trust they would have done extensive R&D to design, fabricate and fit the best and most efficient intercooler they can for any Porsche they work on.
Ask your nephew if he could design and fabricate his own intercooler for the tightly packaged 911 Turbo and let's see what he turns up with?
A Supra with its long nose and huge engine bay and lots of room to run a Front Mount Intercooler and huge diameter piping with soft angled bends is apples and oranges comparison to a 911 Turbo. Too many people in the peanut gallery, lots of people I have noticed have negative comments to share but would not know the first thing about sizing, selecting and fabbing an intercooler.
BTW..I have designed (in AutoCAD) my own intercooler and piping for my 911 Turbo took months to make it perfect.

Those end caps look awful, he is right. The welding on the intake tubing is also pretty bad (especially considering what this thing probably cost). That said, effective intercoolers aren't always efficient.
I think you should be more concerned about the Fabspeed open airbox which has proven to suck in nothing but hot air. Not sure if there is a better option when you get rid of the stock cooler.

Well I have the stock unit sitting on the garage floor. I more or less posting the question as I really don't know the answer as to weather or not it flows well. My car really isn't making all that much power as well, and from the reading I've done the stock I/C is very efficient. Fact is at this point, I really don't need the larger cooler. I don't track the car. But I like the look of it outwardly. It just takes the wind out of my sails when showing off my car and people are asking why I have the crappiest looking design they have ever seen.
The airbox cover appears mickey mouse. Looking at it one would think it came off one of the Ebay buy-it-nows for $9.99. I do have the stock airbox cover but wasn't sure if I could fit it back on with the aftermarket cooler.
So does anyone have the answer as to why they bottleneck the inlet pipes? I would at least like to able to explain to people in the future why it looks the way it does.

yeah, I hear that 16/24s are yesterday's news. they do work like 30% harder up here though so I am needing more heat dissipation
