For the records. My Boxster S had oil starvation problems at the Pocono Racetrack, driving the bowl at almost 100mph. You could hear the valve noise (like a blown muscle car V8 engine). Other guys running the Boxster at the track had similar issues (check the Boxster Racing board). However there are aftermarket auxiliary oil pumps.

At the same track the GT3 reaches almost 130 mph at the same place (higher lateral G force). I just wonder how bad could be the Boxster engine almost 30mph faster at the bowl. I don't use slicks on my cars.

There is a reason Porsche didn't use that wet sump engine block on the Turbo, GT2, GT3.

However, Porsche can always go the same path that BMW with the M3. Get the Carrera S 3.8 engine to rev 8000rpm and then place a recall on connecting rods, pistons, rings, bearings on 40,000 cars down the road.

Whether its the 997GT3 or 997GT3RS one of the two has to have a dry sump in order to homologate the race cars, unless the rules state differently. Which one will it be? Will it be available in the USA?

The fact is that if they choose to use a derivative of the GT1/GT2/GT3 engine with higher displacement or they choose to engineer a new engine is a matter of $$$!! Who knows, the reason why 996 GT3's got the GT1 block was becuase PAG didn't want or could not spend the money (Cayenne took most of the R&D budget) in designing a brand new racing motor...so it was less money to produce one that didn't need a lot of R&D.

I'm glad they did it but remember money is the basis for all automakers' decisions.

Not to mention that is a damn fine badass block!

I just love to see any 993, 996- GT3, GT2, or TT engine and see that 964 part number on them...

Finn: GT3s and Turbos for sure, and probably GT2s, started getting a new engine case with a 996 part number starting around November of last year. It's still a GT1 derived case but the last vestiges of support for air-cooled motors (e.g. oil return tube holes and mating surfaces for cylinder air deflectors) are gone and there appears to be some additional reinforcement webbing. Search in the GT2 & GT3 forum if you're curious on the details.

Flying Finn

Thanks for the clarification Steve.

Interestingly (if my very poor memore serves me correct), I think Marcelo's car had, even though is quite late delivery (dunno about the build date), 964 number when I changed the oil in it.

Marcelo, to the gargage, under the car and check!

FWIW, I have heard the same from my local dealer in regards to the enhanced Carrera S 3.8L going into the next GT3. If true, sounds more like a marketing/accounting move to me.

As late a delivery as MJ had, I would be very surprised if he has the 964 case.

If they make the engine track worthy that is all I really care about... we will finally have a track derived/tested engine and tranny in the normal 911.

But that seems to be far away at the moment....

If Porsche goes with the Carrera 3.8S for the next GT3, I seriously doubt the can extract 420 reliable Hp. My car has more than 400Hp already. In that case, I have other options:

996 GT2
Ferrari 360CS
Ferrari 430
Ford GT
Viper Coupe
Lambo Gallardo
A pair of 2006 Z06

Probably a Carrera GT is Porsche keep depreciating as the Cayenne.

I don't think it can be true.

Homolagation rules require factory to build 1500 (not 100% about the number but its's close to that, for sure not close to 200) "homologation cars" which means GT3 is the "homologation car" (not GT3RS) and that means it will have a dry sump.

"Enhanced Carrera S 3.8L" might be true but I think it will be a lot of enchansing if the case is different.

TT Gasman

Unfortunately, I could see Porsche using the M97 engine in the GT3 and TT. How many GT3 (or GT2s) actually see any track time? It's probably a lot less than you think, and Porsche is aware of it. If they can beef the M97 up to take 400 HP then I would think it could take another 50-60 HP from turbocharging for street use. Suppose they invest another $5-10K per engine to handle the horses, that's still a lot less than a traditional GT1 dry sump would cost (read increased profit). With PAG these days it's always about the profits.

Finn: The GT3RSR race car is homologated from the GT3RS street car, not the GT3 street car, so it seems the magic number is somewhere around 500.

Flying Finn

Steve,

I though they only made (or will make) around 200 GT3RS's..?

Anyways, I tried to find the number of cars manufactures need to produce and only thing I came up was 25 (Maserati web page) and in fact from FIA page (rules) I got the impression that the oil system is free..?

I just hope Porsche won't go sooooooo low that they will pimp out even the GT3...

Sloth

I agree with Steve that the RS is the homologation car for the GT3RSR. It has the revised suspension and aero parts. The standard GT3 is more like the cup car in all reality.

Thats what we are all fearing...

Steve in FL

Finn: Last count on the GT3RS street car I heard was 500 something. Besides the items Sloth mentions there are a few other parts on the GT3RS that were done specifically for GT3RSR homologation. They were listed in an article in Excellence magazine but I'm too busy preparing for Hurricane Frances to dig thru the pile and find which issue.
