Wow. OK then. If they only got up to 90 average on a 14 degree 2 mile banked oval, that is really weak.
I have done numerous easy laps around Atlanta motor Speedway above 150 MPH. I didn’t go any faster ‘cuz the rev limiter stopped me.
But the track does have an infield cycle course. Pretty tight too.

90 average on a 2 mile oval?
I do better than than on Route 40 in my Honda S2000, with a 2.2 liter no turbo 4 cylinder VTEC everyday on my commute.
Top speed 160 (or so I’m told)... not bad for a convertible.
