Redirect airflow from center radiator

[Robert986]

You are absolutely correct TRK!

When it comes to actual aero performance, I can say that at 150Mph it becomes REALLY light in the front, not very planted I´d say. Besides the top vents I´m also adding a decent splitter, I think it will be just about right. Pics will come when I´m done! :-)

Regarding the other thread I´m referring to, I hope I´m allowed to share links to other forums, if not please let me know. Here is that thread anyway, there is a guy (jimk04) who has made a really neat installation, however I believe that it´s a bit too tight behind the rad, so I doubt its optimum from a aero perspective. http://www.planet-9.com/987-cayman-and-boxster-competition/208657-center-radiator-venting-holes-question.html#post2011233


TRK, you are correct, the GT2 duct can be fitted as intended if the side ducts are trimmed, to rough for my taste, wanna keep the side ducts neat and tidy.

Anybody with opinions on the tilted rad? Air bubbles or not?

Re light front.....what is your ride height? Stock ride height and damping will feel very light and nervous at 150. Lowered on coil overs should help

Wow, great inputs guys!

I like the J.fro approach to extend the hoses, I feel that a flipped radiator is asking for problems with trapped air in the radiator.

Btw. I Think that the 996 and 997 chimneys are the same parts: 996.575.325.30.
The splitter I´m adding is the 99650598691, actually intended for the 996 Mk2, but I hope I can make it work.

I´ll sure let you know how it turns out, right now I´m busy replacing a side radiator that had a leak. The bumper cover is at the paint shop so soon I hope to have it all put together.

Good point, It´s on my list, however I try to do one thing at a time to trick myself to forget the cost for each step.. ;-) Also want to verify front clearence with the new splitter Before I decide on lowering.
