The 9A1 motor 3.8 version is the best I have ever had. When we raced the C2S against the 2004 Chipped TT the place where the C2S jumped out infront of the TT was on EVERY shift. It was SO obvious. What I have heard is the 9A1 motor can get much larger than the GT1 motor. Isnt 4.0 the limit for the GT1 motor? Having owned THREE GT1 motors, I see no reason the 9A1 motor cant succeed. I have no emotional attachment to either motor, but the 9A1 motor has 40% less things to break. Reliability SHOULD be better just based statistics.
I believe because of the Rules of racing that the GT3 will have to be normally aspirated right?

You are right to some degree - they have an "extended/grace period" to meet the CAFE/EPA regulations.

I think you misunderstood: I was referring the product strategy which may already be in place for the 991 which will (as I hear) come with a longer wheelbase. Not a mid-engine by any definition of mine, but moving around 100lbs in critical areas and increasing wheelbase could have a dramatic effect on handling...

Each buyer will see such changes as good or bad, but I suspect the only calculus going on at Porsche right now is what set of changes will produce net more revenue and profit.

I personally am not a fan of the idea, but I think it may well sell more cars.

end of an era. every 2 gens... 964 was new era, 996 was new era, 998 (991)....
it's sad, yet exciting perhaps, we don't want porsche to drop the ball.

No not referring to any extended period to meet regulations. The companies i listed simply do not meet CAFE regulations, BMW and VW may meet them now but not in the past. Again, Look at Ferrari's current lineup, they clearly continue to not meet the 25mpg fleet average required by CAFE regulations.

There is no need to worry that Porsche won't meet these regulations in the future, cause the past shows us they haven't before.

Porsche's next generation GT3 will show us what the 9A1 engine is capable of. Clearly we haven't seen its highest potential as far as HP and RPM, and I wouldn't be surprised if the actually HP numbers are a little more conservative given Porsche always likes to leave room for an RS model, and also future model updates. 480HP from a natural aspirated 6 cylinder is getting up there, i don't think i would be too surprised to see an 8 cylinder eventually in the GT3 or 911 series eventually.

RUF has shown its possible with their in house built V8 and the RUF RGT-8 V8 powered 911 and even more interesting is that it weighs less than the 3.8 it replaced.

i actually think it is possible we'll see 3 different engines (Flat 4, 6, and 8) all based on the modular 9A1.

Porsche not really that small anymore.

rosenbergendo

He stressed 3 times-no 8 cylinder. I really really prodded him on this!

So, cheaper engine, more expensive LTW materials = not much price bump? Or, GT3 moves up market toward 458, and cayman has "room to grow"?

GrantG

Maybe not right away, but I think it's possible later in the 991 generation (or maybe in the following generation, 992?).

P.J.S.

call me when the motor has been proven in factory race cars... right now all I see is subaru motor on my caller ID and I ain't picking up

just as an FYI in order to match the 107bhp/litre ratio of the current 3.8L 9A1 the 480 bhp version for the 991 GT3 would have to be around a 4.4L displacement!

I think I see some Ti components ala the GT1/Mezger engine in the 9A1s future ...

I have no doubt that Porsche have the engineering "horsepower" (pun intentional) to extract 126bhp/litre from the 9A1 after all they can get 147/l from the RS Spyder/918 3.4 but that is a V8 ...

I still want to see "my" GT3 engine in a racecar for a while for a whole bunch of reasons...

DKP 97 C2 Coupe

For me, the clearly-proven motorsports history for well over a decade the world over with the GT1-based engine is a big part of the satisfaction of owning a 997.2 GT3. Yes, most likely the 991 GT3 will be faster on the track. But just like the 993, whose desirability only continues to increase as the years go by, I suspect that years from now the 997 GT3's will be fondly revered by us "old school" Porsche guys. And I'm frankly not interested in a PDK car for the track regardless of how much quicker it may be ~~

Larry Cable

Exactly my thoughts too...

mdrums

I totally understand....however as small as it might be there are those like me in this world that need PDK in a GT3 in order to physically be able to drive a GT3. I also bet that if Porsche builds a GT3 with PDK that it will have zero problems selling.
