Tuesday Tech Question

Question:

At last Friday’s 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?

140 Gordy

Answer:

140 Gordy,

In the 2012 NHRA Rulebook in Section 7 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 quicker than 135 mph you must meet the requirements of NHRA chassis inspection, if automatic transmission a SFI 4.1 transmission shield, 30.1 flex plate shield & 29.1 flex plate.  Also, NHRA license, Snell or SFI full-face helmet 2005 or newer, SFI 3.2A/5 jacket and pants, SFI 3.3/1 gloves & neck collar.  The same rules would apply if running E.T. bracket racing.
