Here is why they run restrictor plates - Bill Elliot's "..... qualifying lap of 210.364 mph still stands as the single-lap speed record, as NASCAR mandated restrictor plates for the next year's race -- as a result of Bobby Allison's terrifying crash at Talladega in the 1987 Winston 500 -- and every one since."

I seem to remember some of the late 60's early 70's cars doing 220-230 mph during testing, pretty scary in those 4500lb cars with bias ply tires.
