yup, double checking pole speeds, IMSA runs WAY faster than NASCAR, and for 24 hours straight.
the pole setting speed was 104.9mph, on a 2.28 mile track, thats a 1:18.2 lap.

that video, which is a GT3 Cup car, which is the slowest IMSA class car, is running a .... 1:18.XX lap.
the prototypes run at least 10 seconds faster, as they are both quicker in the corners (downforce) and quicker on the straights (more power).
wow. this is why NASCAR reports lap times in mph, to cover up how slow those cars really are at anything other than ovals.
