Thanks for the response. Your comment on the GT2RS engine is interesting considering Porsche claimed a two turbo flat 6 won’t fit in the 982 chasis... also seems late in the game for a mule with a flat 4 in a mule, as that was only a few weeks ago. You stated things change, so Maybe that means the decision isn’t made yet?

What about all the naysayers who say the flat 6 turbo doesn't fit in the cayman chassis? I still think that is what was on that video

Who is to say that PAG doesn't have multiple variation running around at the same time?

And fit can mean a number of things: like thermal, projected reliability, etc, etc

PAG can have a flux capacitor in a mule at their own discretion, but certainly wouldn’t make any sense. If the GT4 engine selection is as concrete as some say it is, then Curious why they would.

Maybe they are doing other systems tests. Who knows. Why waste a good test mule just because it doesn't have the engine everybody expects.

Maybe not without modification. IIRC modifications were made to the current GT4 engine to make it fit, also.

Air intake, oil filter and exhaust IIRC. Moving around 2 turbos might be a completely different story as tcsracing1 has previously posted.

I heard that the Speedster might get the full 520hp from the RS (or more than 500 anyways).

As far as preserving the hierarchy, the Speedster is going to be expensive (price beginning with a 2 - maybe close to a 3). No worry about stepping on toes at that level...And it’s a numbered limited edition.

That would be some beast of a convertible and a non GT dept product at that!

I would love to get a ride in the mule

They might have fitted a flat six with turbos (for what ever reason?)... but it wasnt the configuration of the 991.2 Carrera S motor as it would have the turbos in the driver and passenger compartment given the length.
They would have to relocate the turbos etc to shoehorn the engine in the chassis which would be a waste of time IMO.

Kinda like putting a square block in a triangle. You would have to cut open the triangle or stack everything on top of the triangle....

I realize this is take-it-or-leave-it info without a warranty, but I don't buy it. Manufacturers don't waste resources like that. Trying out two different concepts on the road would be unusual, but possible. But engines that clearly don't fit while having no possible use in this platform? No way. They know pretty much exactly how the cars will perform (in all aspects) even before they put an actual engine in them. By the time it gets to extensive road testing like we've seen them do we are really talking about calibration and final evaluation plus the obvious reliability testing in different climates. A GT2 RS engined mule sounds like pure pub talk and makes no sense on any level.

Don't get too hung up on the GT2 comment. Has anyone even remotely spied one doing actual road testing? You and I don't know what Porsche does and doesn't do and why. Never underestimate a bored engineer with nothing else to do on a Saturday night and blessings from management. I know I've done some weird stuff programming that's now widely used at my company because I was bored and wondered "what if?"

It's entirely plausible that the video surfaced of the flat 4 but all the actual spy shot times the mule was running around with the 4.0. Those are more secluded from the average joe and thus Porsche can control it easier. Besides, all those times were in extreme weather (snow/ice).
