Hello everyone , it's been a long time since I posted anything, finally found the time to post something on my blog that might interest 997 Turbo Owner's. After doing a few modifications to my own 997 Turbo I figured I would take a look at what really matters, one thing is for sure is that the factory Turbo Air Intercoolers are poorly designed , they might be almost efficient for a completely stock 997 Turbo but that's still questionable. As you can see by the pictures below the stock 997 Turbo Air Intercoolers have very thin charged air tanks in other words the charged HOT air that the turbo pushes into the Air Intercoolers on the charger side is in my opinion poorly designed in directing the Charged Air through the core efficiently, yes of course its better than having nothing and at least the 997 Turbo intercoolers really get fresh air from the outside to cool the charged air, but as the charged air enters the Intercooler it appears that most of the charged air will travel through the middle fins which means that what goes out of the intercooler is of course cooled down a little but not enough, if you don't already know, the cooler the air that enters the intake the more power your engine will make in other words some HP gains will occur. Below is a picture showing the charged air tank on the intercooler I pointed a few arrows that tell the story. You will also notice two X's that point to the area where hardly any charged air will get there.
The modifications involved to fit these is to drill 6 holes on the lower air ducts and cut the interior lips on the air ducts. because the core is thicker the attachment system will no longer work, I mean the upper and lower air ducts are kind of attached via a strap system, so you will have to drill holes on the lower ducts so you can attach them with tie raps. In addition the interior lips must be cut off with a utility knife so that the air ducts sit flat on the intercooler, those are the only mods necessary. See pictures below.
Maxspeed-Motorsports.com will be offering the 997 GT2 RS Intercoolers very soon, this will be part of a power package that will include additional parts to accomodate the extra HP's. Hope you enjoyed this article.
