Oil-retention Device

Beginning Jan. 1, 2007, all Comp competitors will be required to have an oil-retention device meeting either SFI Spec 7.1 or 7.2. For Jan. 1, 2008, the same rule will apply for Super Gas, Super Comp, and any E.T. vehicle running 9.99 or quicker or 135 mph or faster. NHRA is developing an implementation strategy for an oil-retention device meeting the SFI specification for the reminder of the NHRA Lucas categories.


Head And Neck Restraint System

Effective Jan. 1, 2007, NHRA will require all competitors in Top Fuel, Funny Car, Pro Stock, Top Alcohol Dragster, and Top Alcohol Funny Car to utilize an SFI Spec 38.1 head and neck restraint system. Certain classes in Comp (A/D, A/DA, B/D, B/DA, H/D, A/ED, AA/AM, AA/AT, BB/AT, CC/AT, A/AP, A/A, A/AA, B/AA, A/PM, and AA/PM) and any alternative sanctioning organization vehicles that run 200.00 mph or faster must also have a head and neck restraint system meeting SFI Spec 38.1 for the 2007 season.
Helmet Expiration Dates

Effective Jan. 1, 2007, where a Snell- or SFI-rated helmet is required in competition, the Snell 95 and SFI 31.1, 31.2, 41.1, and 41.2 helmets will no longer be allowed. Look in the General Regulations section of the 2007 NHRA Rulebook under Helmet and Goggles for expiration dates for all Snell and SFI-tagged helmets.
Taillight

For all NHRA Sportsman and E.T. racers, a functional light must be visible from the rear of the car. This eliminates all reference to night racing only, meaning a light must be functional at all times.
