From a Viofo A129 duo dashcam.
Two high-performance Porsche Cayman GT4s having fun at a PCA HPDE event at Virginia International Raceway. The 981 is 3.8L 385 HP model manufactured in 2015 and 2016. The 718 is a 4.0L with 414 HP that weighs slightly more than the 981. The 981 street version was only available with a six-speed manual transmission (the 981 Clubsport GT4 has PDK standard) . The 718 has manual and automatic (PDK) available. This one was PDK.
The 718 begins behind the 981, but the 981 (me) gives a point by on the next lap. Ignore the time stamp, it's wrong. Speed readout is somewhat accurate, but it lags. The 981 is stock except Fabspeed sport headers and max aero; tires were Sport Cup 2s.
The video view "resets" due to the dashcam saving in 3-minute-long files and the fact that my video editor (Movavi) can't carry over zoom/pan settings from one track to the next.
