CLASSES YOU WILL SEE:
Top Alcohol Dragster
Top Alcohol dragsters may look like Top Fuelers, but they have significant differences. Whereas Top Fuelers use supercharged, nitro-burning engines, Top Alcohol Dragsters may use a supercharged methanol-burning engine or an injected nitromethane combination. The injected nitro cars do not use a transmission, and the supercharged cars have three forward speeds. Weights vary according to combination but are generally between 1,975 and 2,125 pounds. Like Top Fuelers, Top Alcohol Dragsters are restricted to a maximum wheelbase of 300 inches. Performances can be in the 5.1s at more than 285 mph.
Top Alcohol Funny Car
Similar in physical appearance to their nitro-burning Funny Car counterparts, Top Alcohol Funny Cars are restricted to the use of methanol fuel and have a three-speed transmission. Top Alcohol Funny Cars feature basically the same chromoly steel chassis as the nitro cars and are fitted with the same carbon-fiber replica bodies, though the Top Alcohol Funny Car bodies do not need as much downforce and use a much smaller rear spoiler. Top Alcohol Funny Cars are capable of performances in the 5.3s at more than 270 mph.
No category in NHRA competition features more variety than Comp. Dragsters, altereds, street roadsters, coupes, sedans, front-engine nostalgia dragsters, sport compact cars, and trucks race in 75 classes. The engine combinations are just as diverse as the vehicles, from turbocharged four- and six-cylinder engines to Pro Stock-style V-8s and nitrous-oxide-equipped mountain motors. Most cars are classified using a formula that divides total car weight by cubic inches. Each class is assigned an index based on what a well-built car should run, and races are handicapped according to those indexes.
Top Sportsman & Top Dragster
Essentially a pair of categories for fast E.T. racers, Top Dragster presented by Racing RVs (open-wheel entries) and Top Sportsman presented by Racing RVs (full-bodied cars) feature a qualified field of 32, 48, or 64 entries. Competitors may choose their own dial for eliminations provided it is not slower than 7.99 seconds (8.19 in Divisions 6 and 7). Eliminations in both classes are run using a traditional bracket racing format with a full three-amber Christmas Tree start, and the breakout rule is enforced. It is not uncommon for entries to run in the sixes at more than 200 mph.
Stock cars are similar to Super Stockers, but the rules regarding everything from engine modifications to body alterations are much stricter. Virtually any car is eligible to compete, and entries are classified using a system that divides factory shipping weight by NHRA-factored horsepower. Bodies must be unaltered and retain a full factory interior. Tires are limited to a maximum 9-inch-wide rear slick. Engines must be correct for the make and model vehicle and must retain stock cylinder heads, intake manifold, and carburetor. Modifications are limited to a basic balancing and rebuild with only a few performance enhancements.
Super Stock vehicles may look like ordinary passenger vehicles, but they are highly modified race cars. The category features primarily late-model sedans and vintage muscle cars, and entries are classified using a system that divides factory shipping weight by NHRA-factored horsepower. Significant engine modifications are permitted, but the vehicle must retain the correct engine block, cylinder heads, and carburetor. Cars are handicapped using an index system, and the breakout rule is enforced.
Super Gas entries, which run on a 9.90 index, are primarily full-bodied cars and street roadsters. No dragsters or altereds are permitted. Rules regarding engine and chassis modifications are extremely liberal, though the use of exotic fuels is prohibited. The minimum weight is 2,100 pounds except for four-cylinder-powered cars, which may have a minimum weight of 1,200 pounds. As in Super Comp, competitors use electronic timers and throttle stops to run as close to the class standard without going under. Also as in Super Comp, races are staged using a four-tenths Pro start.
The quickest of the heads-up Super classes (8.90 index), Super Comp is composed primarily of dragsters. Engine, chassis, and body modifications are virtually unlimited. Four- and six-cylinder-powered entries may have a minimum weight of 1,000 pounds; all others cannot weigh less than 1,350 pounds. Most Super Comp cars are capable of running well under the 8.90 index but use a number of electronic aids, including a timer and adjustable throttle, to run close to the index without running quicker than it, or breaking out.
At NHRA Lucas Oil Drag Racing Series races and select NHRA Mello Yello Drag Racing Series events, Super Street racers compete on a fixed 10.90-second index. All vehicles must be full-bodied cars and weigh no less than 2,800 pounds except for six-cylinder cars, which may have a minimum weight of 2,000 pounds, and four-cylinder- and rotary-powered cars (1,200 pounds). Engine and chassis modifications are virtually unlimited. Racers compete on a five-tenths Pro Tree.
