997.2 or gt2rs cooler fix - Page 3 - 6SpeedOnline - Porsche Forum and Luxury Car Resource

I've been running the 997.2 IC's successfully on a road course at 1.3 bar for 100+ track hours. The only intercoolers I'd swap to would be Marstons or Secans but they're big $$$. With that said, I just did a boost leak test on my car today and see that the right side IC has a small leak at the end tank. I'm going to pull these and glue them as has been done by other. I could not find the link, but does anyone know what glue is recommended to bond the end tanks to the cores? Thx!

My client has 9ff 3.8l motor and other goodies as he lived close to them and runs 1.6 bar on a2873s. Guess who's 4.5" Ics are on the car. And he would never ever put on the gt2 rs. He actually says that those who believe in gt2rs Ics will never understand nor ever admit that quality bar n plate Ics are thag much better. He actually is an engineer himself who also is a tuner so data logs and graphs is what he lives by. There is more to it then just watching Intake temps on Ics which is all that everyone does. Sure they will recover sooner - the fin design and the lesser mass but what will they do with for when flow and volume really matters to some. There is always a compromise to everything. There are guys who will never put on a rs Ic just like there are guys who will never spend $3k on really good Ics. Yet they will over spend on boost hoses or intakes covered with fake carbon to make them selves feel better. Whatever makes you happy. In the end it's your car your money. I e been down this road a many times since 2001 and made many mistakes. THats how I leaned.

I have little doubt that your ICs work and that they are worth the money you ask. But as you say, everything is a compromise. Bar and plate can be great - but they are heavy. And there is a huge difference in needs if someone wants to go fast in a straight line or if someone is trying to optimize the car for track use. And if you are removing bits of foam from the back of the carpeting to save weight from the middle of the car where the polar moment of inertia is next to nothing, you are definitely going to think 3 times about hanging some heavy chunks of aluminum in the rear corners of the vehicle where a. there is already too much weight because the motor happens to hang there and b. the polar moment of inertia could hardly be greater without going outside of the car's body.

I've read plenty of Andreas' posts on German boards (I assume he is who you mean) and know what he is trying to achieve - and it is not the same as I am trying to achieve (and people like Powderhound are going to even much greater extremes than I).

Comparing using GT2 RS ICs to sticking carbon on intakes is a bit off base. It's not as if these are junk purchased through Alibaba and they have been proven to work - not just here on the board but by Porsche. Who also run 1.6 bar through them in the GT2 RS as ghost pointed out above. And, we are not hearing about ICs blowing up on GT2 RS's everywhere.

I am sure that your ICs flow better and cool the charge well, but as you said: everything is a compromise.

All that said, I've asked about the weight of your ICs before...
