997 GT3; dry sump
You've probably seen this:

"The X51 upgrade provides the 3.8-liter flat-six with a carbon fiber air cleaner housing, a larger throttle body, revised intake, cylinder heads and exhaust manifold modifications. It also includes engine control unit changes and a sport exhaust system. Porsche says the Club Coupe needs just 4.4 seconds to reach 60 mph and is capable of a 186 mph top speed, compared to 4.6 seconds and 182 mph for the Carrera S. Porsche also notes the Club Coupe is the most powerful normally aspirated car it has ever offered for sale in North America. The previous benchmark, the 2004 911 GT3, featured a 3.6-liter engine that produced 380 hp and 284 lb-ft. The Club Coupe won’t hold the title for long, as the 3.8-liter found in the 997 GT3 slated for launch later this year should produce somewhere around 400 hp."
With the X51 package out for the 997S, I have difficulty believing that the 997 GT3 will simply be a X52 package. Rather, a 3.8L dry sump motor having some of the extra breathing tricks from the current RS would make more sense to me.

Well thats a lovely blue, and the wheels are nice.
I would not like to make any assumptions about sump arrangements based on this, however. It really doesn't matter. In the event that the engine has a wet sump, then this is a nice conversion for the better tuners, if it is required.
Two of the newest engines are the BMW V-10 and the Lamborghini (V10). The former is wet sump, the latter dry sump, despite being part of the Audi V8 family (same bore centres), which has a a 'wettish' sump.
So which route will they take....... careful analysis might reveal a clue or two.

I think a lot of folks here have been using the term 'dry sump' to indicate not only the oiling mechanism, but the origination of the motor, that is, whether it originates from the boxster or from a race bred, race proven drivetrain.

Jeff, I had the same exact feeling and posted it on another forum. It's like Porsche is saying, well the 3.8 makes 355 hp, no wait, it makes 381 hp, just kidding, if we really try it makes 408 hp. To me it just fuels the opinion of many that the Carrera S should have had 381 hp stock.

Yes, wait and see... But if I was you, I wouldn't believe you...
Why? Flying Finn, I would imagine you don't do or see any Porsche development work? Talk to your Alex Job friends down in Florida.
Do you honestly believe a GT3 would be sold with a wet sump if its RSR's are racing with wet sump? Maybe you are right, I don't know for sure on the street car side- I'm just making an educated guess based upon information that most people might not realize.

Why the move to wet-sump, I can see why in the street cars (cheaper to produce), but doesn't make sense in racing? Is Porsche switching just so it can sell b.s. wet-sump street cars to us fools?

vegas,
I don't know about RSR's oil system but if they are wet-sump, it certainly makes sense to have street cars wet-sump also (and no doubt that would be good system if RSR's survive with them).
