Introduction to NHRA Drag Racing
NHRA, short for the National Hot Rod Association, is the premier organization for professional drag racing in the United States. Founded in 1951, NHRA has grown to become a global powerhouse in the motorsports industry, attracting top-level talent and passionate fans from around the world. NHRA events feature a wide variety of classes, each offering a unique racing experience.
NHRA Stock and Super Stock Eliminators
At the heart of NHRA’s drag racing classes are the Stock and Super Stock eliminators. These classes provide a platform for both seasoned veterans and up-and-coming racers to showcase their skills and compete for glory. The Stock and Super Stock eliminators are defined by a ratio of vehicle shipping weight and a horsepower factor, as outlined in the NHRA Stock Car Classification Guide.
Understanding the NHRA Stock Car Classification Guide
The NHRA Stock Car Classification Guide serves as a crucial tool for positioning vehicles in their proper classes. The guide includes comprehensive information about years, makes, models, and engine combinations, allowing racers to determine the appropriate class for their vehicles. It provides power-to-weight factors for each model and engine combination, enabling racers to identify their vehicle’s class based on its factor.
The Power of Weight and Horsepower
In NHRA drag racing, the power-to-weight ratio plays a significant role in determining a vehicle’s class. The power-to-weight ratio is calculated by dividing the vehicle’s weight by its horsepower. This ratio reflects the performance potential of a vehicle, making it a crucial factor in class placement. Different classes have specific power-to-weight ranges, ensuring fair and competitive racing across the board.
Stock Car Classification Guide
The NHRA Stock Car Classification Guide is a comprehensive resource that lists all years and makes in the NHRA Stock Car Classification system. The guide provides detailed information about each vehicle’s engine, horsepower, and power-to-weight factors. By referring to this guide, racers can easily identify their vehicle’s class based on its specifications, ensuring they compete in the appropriate category.
Super Stock: Pushing the Limits of Performance
Super Stock is an exhilarating class that pushes the boundaries of performance. In Super Stock, vehicles are highly modified race cars that may resemble ordinary passenger vehicles but pack a punch under the hood. The class features a wide range of late-model sedans and vintage muscle cars, each classified based on a system that divides factory shipping weight by NHRA-factored horsepower.
Unleashing the Thrill: Super Comp and Super Gas
Super Comp and Super Gas are two heads-up Super classes that offer thrilling racing action. In Super Comp, the quickest of the Super classes, dragsters dominate the scene. These high-performance machines feature virtually unlimited engine, chassis, and body modifications. Super Gas, on the other hand, primarily consists of full-bodied cars and street roadsters. The rules regarding engine and chassis modifications are liberal, allowing for intense competition.
Super Street: The Battle of Full-Bodied Cars
Super Street is a class that showcases the power and performance of full-bodied cars. Competing on a fixed 10.90-second index, racers in Super Street unleash their machines on the track, pushing the limits of speed and precision. With virtually unlimited engine and chassis modifications, Super Street offers a thrilling battle between some of the most powerful cars in NHRA drag racing.
Top Dragster and Top Sportsman: The Fast and the Furious

Pro Mod: The Ultimate Showcase of Diversity
Pro Mod is a class that celebrates diversity and innovation in NHRA drag racing. Featuring an eclectic mix of vehicles, including classic models and late-model powerhouses, Pro Mod offers an incredible display of engineering prowess. Competitors in Pro Mod can choose between superchargers, turbochargers, or nitrous-oxide injection, pushing their machines to the high-five-second zone at speeds of over 250 mph.
Factory Stock: Showroom-Ready Powerhouses
Factory Stock is a class that brings the power and performance of showroom-ready muscle cars to the drag strip. Showcasing Chevrolet Camaros, Ford Mustangs, and Dodge Challengers, Factory Stock battles are a true display of raw power. These head-to-head battles feature cars that can reach speeds quicker than eight seconds and faster than 170 mph, providing an exhilarating experience for both drivers and spectators.
Top Fuel Harley: Thunder on Two Wheels
Top Fuel Harley is a class that showcases the thunderous power of nitro-burning motorcycles. These awe-inspiring machines retain the features of the Harley-Davidson engine, a pushrod V-Twin, and traverse the quarter-mile at breathtaking speeds of well over 200 mph. Due to the violent nature of these 1,500-horsepower fire-breathing machines, riders start their bikes before getting on top of them, adding to the adrenaline-fueled excitement of the class.
