On 987 cars, they have a true harmonic dampner which is why you have to buy a much more expensive underdrive.
On my 987 the OEM pulley did Not have a balancer.., but I replace it with an UDP to reduce the speed of the accessories after frying three steering pumps on the track (thankfully replaced under warranty) and it's been installed on the engine for at least 20k without any issues with the water pump on the SoCal summer with heavy traffic..

I believe that the only 987's that came with the dampened pulley are the engines on tye GT3 and perhaps the 987 Turbo 911's
