718 GT4?

Still think no GT motor?
Porsche focus the brand around the 911.
Having a Cayman with too much power would put it too close to the 911 GT3.
Porsche feel the Cayman market is sufficiently covered with the GT4 as top of line Cayman with no need for an additional RS model.
It will be very interesting to see what happens with the 992 GT3 engine..... given that the 2017 Cup cars are going to be running without turbos for awhile, perhaps we shall see no turbos in the 992.1 GT3 series.
I wonder if porsche will eventually make hybrid GT3 and Cups?

This does not surprise me. I had a 718S in my run group at Barber, a nice technical track, last year. Good driver. I could get ahead of him over time but it was WORK. And when we were close, and pulling out of low-speed corners, I couldn't believe how he was staying right with me, even when the GT4 was up in the revs.

I've seen a lot of mention that the 991.2 motor won't fit, but how then do tuners like TCS get turbo systems to fit fine in 987 and 981 applications (on the larger 3.4L)? Surely Porsche can do it if the tuners can? On the GT4 v. lesser Caymans on track, a large part of the difference being slim is the trans IMO. My PDK 981 Cayman S with headers and tune is pretty close on straights thanks to nearly instant shifts. Not that I wouldn't trade mine for a GT4 if I had the coin...

Previous aftermarket turbos were installed as afterthoughts and engineered as such. Not an engineered warranty porsche design by any means. Porsche factory do things much different than tuners.

Take a look at the You Tube post a few hours ago by RSRNurburg showing a stock 718 Cayman S dynoed at 373 hp, 23 more than stock spec. You have to infer that the stock GTS motor would dyno proportionally higher as well. Given the torque numbers for the S and GTS, I would think there is a serious chance that a NA motor with 400-420 hp is simply not going to perform sufficiently better (if it does at all) to justify calling the next gen car a GT4. The performance of the 2.5 turbo four in the S and GTS makes taking the high-revving, high hp heart out of the GT3 motor not an option. Perhaps that explains the sporadic noise, including through dealers, about an “RS” label.
One thing is for sure, the 718S and 718GTS are very capable cars.
The 6cly GT4 would want 400-420hp to outrun a stock GTS on the track which is what will most likely be the case.

While far from conclusive, seeing a Spyder (same exhaust, diffuser, big brakes etc as the GT4) testing in the wild with a 4 pot turbo is not the best sign we could get.
