What did you do to your 996TT today?

Walked amongst the parts
Not so much what I did But what my Indy did to the 996tt.
Getting a new clutch and a few “while you are in there” stuff. So much ancillary (billable) effort to replace a clutch..

My 996TT is in hibernation, but I found these gray inner door sills on -bay covered in leather and needed to have them. I know gray is not everyone's cup of tea, but other than cinnamon brown it's my favorite on the 996.

@Scawt Tell me more about this mod! Are you going for GT2 style radiator venting?
#4297
Yep, GT2 ducting and radiator. I got the idea and template from this old thread: https://rennlist.com/forums/996-gt2-...tor-slots.html

After almost 3 months I could drive it. I cycled the rear spoiler to keep it working and forgot it in the up position overnight. Next day the left side lowered but the right didn't and there was a noticeable leak from the motor area. So I removed the whole system bled and refilled. Now all is good. Guess I'm getting good at it. It only took me about 1 hour. I also noticed the coolant is low. Guess it's the same as before leaking radiator. I changed the right 2 years ago so guess it's time for the left.

[QUOTE=Scawt;15550380]I'll take some more downforce please
[/E]
Not to rain on your parade, and perhaps you really don't care about functionality, but have you done any aerodynamic testing of the mod you are doing? It is one thing to cut holes in the front bumper it is another thing to get the air to be directed as it is with the GT2 bumper. The GT2 has specifically designed slats in the openings...I suppose those have a function?

If I was running a 996TT with a larger rear wing, I would absolutely positively do this very same mod to create more downforce in the front.

This isn't rocket science. Both the 996Cup and 996GT3RS simply vent the center radiator up over the hood in this EXACT same fashion without any behind the bumper ducting (ala GT2), they simply have the center radiator canted forward. In both those applications the bumper is sealed at the bottom (as Scott will be doing) to prevent any air from flowing under the car, instead flowing up an over the hood. The center duct used on the GT2 behind the center radiator does make the airflow through the bumper smoother likely improving the cooling efficiency of the center radiator but again, it's not rocket science as the main goal is to eliminate the air from being diverted under the car (as is done on the 996TT) which results in unwanted front axle lift. The GT2 duct (which Scott may be installing based on his post) will smooth the airflow and the GT2 slats (which he is not installing) will provide a low pressure area above the opening in the top of the bumper helping to pull the air through the bumper. In any case, what Scott is doing is a proven mod done by both Porsche Motorsport and others...

Thanks for your explanation...not sure why you're so hung up with rocket science...nothing wrong with science. The thing about science is you develop hypotheses and test them with data. Doesn't matter whether you are applying this to the aerodynamics of rocket flight or an automobile. That is all I was suggesting. If this is so obvious why doesn't this come standard? I know, because they (Porsche, et. al.) are continually experimenting on how to get the best performance/cost benefit...each iteration over the years has attempted to improve and my bet is it will continue...Please don't be offended by my suggestion to test the effects of the mods.
