Here is one lap from Willow Springs wherein Samy can be seen doing about 130mph (watch my speedometer) on the main straight.

Total length is about 2 minutes.

Description from youtube:

One lap of Willow Springs in a Hellcat. Hellcat reels in a Lotus Elise and Samy in his 1968 Dart (and all three reel in a 911 along the way), but not before Samy impressively hits about 130mph on the main straight.

Note that this is not a race, but a gentlemanly Track Day where passing is restricted to three specific areas of the course.
