At Blackhawk, Road America and the Milwaukee mile I routinely have been able to pull over 1.2 G's lateraly.
Last Thursday at the North hairpin turn on the Milwaukee Mile, the car showed 1.37G.

Not a 991, but a 981 on a track (not mine)

Dewinator and Jay-S, do you guys have the carbon ceramics for brakes? 1.27 is very impressive. After two days at Watkins Glen I'm pretty sure my max was under 1.20 for braking.
I agree the camber in a turn has a big impact on g-force obtainable. There are some great right turns at WGI. I'd bet that the best g's were in Turn 1, which has good camber (and plenty of run-off space). The car was on P-Zeros at 39 psi hot on all four (this was the first time I was able to achieve matching, which went against what I thought was best for a 911 on track, but what I really know is basically not much). The ambient air temp was probably about 80 degrees F. Another big factor was a nearly brand new really smooth and sticky track surface. I had maxs of 1.51 turning right and 1.39 turning left. I think acceleration was 1.14, but I didn't pay enough attention to that one before I cleared everything.
The above figures have absolutely nothing to do with my driving skills, or more likely, the lack thereof. The GTS with a sprinkling by the Cobb "Magic Port" seems to have developed a new and aggressive personality. And that's with just the GTS OTS 93 Octane mapping. Only God knows what a car-specific pro tune would produce. I'll just be the same semi toilet-trained chimp with a bigger sxxt-eating grin.
