Thank you to @ralphmusic for finding these links
In that case it's a 6-cyl with CDA...

(I will happily be corrected once we know... )

Yes, stated by many, however none of them were Porsche. That's the only statement that even remotely counts.

In that case why even participate in this discussion if the only one you trust is PAG?

I guess I interpret his comments as, nothing is official. However, some posters are still being quoted as truth.

Jeff, who did the audio analysis of the Spyder while it was on the Autobahn, and determined it was likely a 6-cylinder BEFORE the Nurburgring videos came out is still of the opinion that it is probably the NA 4.0L H6 after listening to the Nurburgring audio: https://www.porscheclubgb.com/forum/FindPost/996271

Edit: He does acknowledge that it Could be the TT H6 however.

Turbo 6 !!! I'd bet money that's the 3.0T.

My original guess was that porsche would follow the GT / Spyder protocol established with the first car. Specifically - Install the carrera motor in the car with a slightly different tune.

Those "fit" dudes were wrong. Just remember the GT4 chassis was different from the Cayman S / GTS.

This has become very interesting. Whoopsy seems to be super sure and he has super awesome cleaning ladies.

So maybe porsche will have the spyder be 3.0T and the GT4 be a 4.0? I still doubt that. The 911 boys would cry all day long if they put an engine that special in the GT4.

Fingers crossed they do. With that said, if the new GT4 is 3.0T I may spec it out and try it before getting my deposit back. The current GT4 engine is just so damn great sounding.

The N/A is already running alot of heat in engine bay. Turbo would not be the answer to the heat issue in a race car.
The rear suspension is something that porsche do not want to match to the performance of the 911....

Id take that bet.
You need my paypal account now or later?

Check out the Porsche PET diagram of the 3.0L Carrera turbo motor and compare it to the PET diagram of the 981 3.8L and you will see why it will not fit.... (it is too long)

How do you explain the sound? And why do you think they wouldn't redesign the turbo plumbing and the body in white?

I can see the logical reasons for not going turbo but I don't see how the actual recorded sound, on several occasions now, squares with an NA engine. It just does _not_ sound like the 3.8 or 4.0 H6 NA engines that we know. Like, at all. The particulate filter is a wildcard here but I would imagine that whatever they have been testing extensively on the road and now the track is what they intend to produce, and a month ago Preuninger sounded to me like they were not at all ready with the filter solution for the big NA engine.

What we have seen (heard) in the real world now has to carry a bit more weight than hearsay or logical deductions based on educated guesses. It does not rule out the NA by any means, but guessing between the two I'd have to go with what it sounds like.

bingo... I hear a lot of ‘trust me’ comments in this thread from folks. Not one has providing anything that isnt circumstantial. You bring up the huge elephant in the room no one is addressing... the th GT3 4.0L doesn’t meet new euro emissions standards. All new GT3s and GT3RSs are being made for the 2018 model because of this. Anecdotally, several Porsche offices were raided by German police yesterday looking for evidence associated with the emissions scandal. Emissions are a pretty big deal for Porsche and VW right now.

Can the engine bay be modified to accommodate? One theory I have is, if they are able to make changes to the engine bay and the turbo plumbing (and whatever else), they may be considering dumping turbo-4 for the entire Boxster/Cayman range. Turbo-4 may have favorable tax implications (less cylinder count and capacity) in countries like China; but, has negative marketing implications in the US (and possibly EU/UK). So, this Spyder proto could be testing a turbo-6 for rest of the range? If so, they could have different engine configurations for respective markets (though not ideal for a number of reasons).

Agree. The filter and the overall limit on db levels could be wrecking the sound. And, this car could be testing with the new regs and PSE off. If so, we may still have some hopes to uncork the sound.
