Promedia, the parent company of the National Muscle Car Association (NMCA) and the National Mustang Racing Association (NMRA) revealed on Friday the preliminary rules set for the new Street Outlaw category, which was announced at the recent Super Bowl of Street Legal Drag Racing in Chicago and will debut in both of the popular heads-up series in 2013.

Street Outlaw, which will bring together the exciting NMRA Super Street Outlaw and the NMCA/NMRA 275 Drag Radial categories into one new hybrid eliminator, has been on the drawing board at Promedia’s Santa Ana, Calif. offices for several months, and the technical and event staff have poured over more than five years of data from racing events across the country to devise what they believe will be the perfect venue for 275 Radial/True 10.5 heads-up drag racing.

The new class will feature six common engine combinations: small block nitrous, big block nitrous, small block supercharged, small block turbocharged, small block naturally aspirated, and big block naturally aspirated. These have been the essential combinations not only in the existing NMRA and NMCA categories, but elsewhere in the small tire racing world, and by minimizing the number of possible combinations, so too can officials minimize performance disparity.

As revealed in the earlier announcement, the category will be open to 28×10.5 slick tires and 275/60/15 radials. Interestingly, in an effort to get more racers involved, Street Outlaw will not be limited to stock-style rear suspension or boast a weight penalty for those on ladder bars or four-links. As long as it maintains the stock frame rails, its legal to race.

Internet message boards have already been abuzz with discussions on the new class and the performance potential, and with Promedia revealing it as a solid 7.20 category, it should effectively blend the record performances of the Super Street Outlaw and 275 Drag Radial classes.

Promedia is continuing to collect data from racers and sanctions in an effort to provide (at least from the outset) the most feasible rules package possible, with hopes of revealing the concrete class regulations by September to allow ample time for racers to make adjustments and purchase parts.
