Question:

At last Thursdays test & tune my Super Street Turbocharged Mustang ran 10.20 at 140 mph and I was not allowed to make any more runs unless I ran 135 mph or slower.  I thought if I ran 10.00 or slower in the 1/4-mile then mph was not a factor?

Answer:

In the 2018 NHRA Rulebook in Section 8 Super Street, page 1, Designation, third paragraph, it states “Any vehicle running faster than 135 mph must meet minimum requirements for 9.99-second vehicles.”  This means if you run faster than 135 mph you must meet the same requirements  as running 9.99 seconds or quicker.
