![]() ![]() ![]() All vehicles must be full-bodied cars and weigh no less than 2,800 pounds except for 6-cylinder cars, which may have a minimum weight of 2,000 pounds, and 4-cylinder- and rotary-powered cars (1,200 pounds). Most Super Comp cars can run 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.Īt NHRA Lucas Oil Drag Racing Series races and select NHRA Camping World Drag Racing Series events, Super Street racers compete on a fixed 10.90-second index. Engine, chassis, and body modifications are virtually unlimited, though all entries must adhere to NHRA safety standards. Four- and 6-cylinder-powered entries may have a minimum weight of 1,000 pounds all others cannot weigh less than 1,350 pounds. The quickest of the heads-up Super classes(8.90 index), Super Comp is composed primarily of dragsters. Each class is assigned an index based on what a well-built car should run, and races are handicapped according to those indexes. Most cars are classified using a formula that divides total car weight by cubic inches. The engine combinations are just as diverse as the vehicles, from turbocharged 4- and 6-cylinder engines to Pro Stock-style V-8s and nitrous-oxide-equipped mountain motors. Dragsters, altereds, street roadsters, coupes, sedans, front-engine nostalgia dragsters, sport compact cars, and trucks race in 87 classes. No category in NHRA competition features more variety than Comp. A typical quarter-mile run is in the 5.2-second range at more than 270 mph. Like Top Fuelers, Top Alcohol Dragsters are restricted to a maximum wheelbase of 300 inches. Weights vary according to combination, but are generally between 1,975 and 2,125 pounds. The injected nitro cars do not use a transmission, and the supercharged cars have three forward speeds. Whereas Top Fuelers use supercharged, nitro-burning engines, Top Alcohol Dragsters may use a supercharged methanol-burning engine or an injected nitromethane combination. Top Alcohol Dragsters may look like Top Fuelers, but they have significant differences. Fuel injection is permitted, and spec gasoline is the only fuel allowed. ![]() To ensure a level playing field, the pushrod-equipped V-Twin engines are limited to 160 cubic inches, and the high-winding 4-cylinder engines cannot be larger than 101 cubic inches. The class features a wide variety of makes, models, and engines, including V-Twin entries from Harley-Davidson and Buell and inline 4-cylinder-equipped Suzuki and Kawasaki models. These highly modified vehicles, which can run under seven seconds at more than 195 mph on the quarter-mile, featuring a purpose-built tube chassis and a lightweight, aerodynamically enhanced replica of original bodywork. Here are 20 pictures of some of the weirdest race cars ever made, showcasing how crazy some designs can be for the track.Pro-stock-motorcycle PRO STOCK MOTORCYCLE Other times, they were just too radical for any period yet made for a fun sight on the track. Sometimes, the concepts were ahead of their time in how they worked and could have done better in another era. Yet, some are daring designs that actually did end up seeing major success. A few had good ideas but then messed them up in the execution. More than a few teams have come up with stuff they thought would be fantastic, only to discover it just doesn’t work in real life. Of course, some designs are just too weird to work out. The results have been some truly innovative automobiles with designs that look like they're straight out of a cartoon-and yet sometimes, they end up somehow working well. The rules are different in Europe, as the Le Mans competition rules actually encourage car owners to bring up some unique designs for their cars.
