Sorry it was 2000. They came 2nd in that class at 150.3mph.
Only 2 finished in that class with 3 DNF.
In other classes some disqualification for I think going below the set speed limits, there being a maximum as well. Probably a 20 mph either side of the class speed.
At the high speeds the radiators could be punctured by flies never mind stones.
They did the 90 miles in just around 36 mins the road being the N 318 near Ely, Nevada. Heading to Crystal Springs. It runs through desert type country.
