Although a quarter mile (1320 feet, 402 m) is the best known measure for a drag track, many tracks are eighth mile (201 m) tracks, and the premiere classes will run 1,000 foot (304.8 m) races. The race is begun from a standing start which allows three factors to affect the outcome of the race: reaction time, power/weight ratio, and traction.
Drag coefficients in fluids with Reynolds number approximately 10 4 [1] [2] Shapes are depicted with the same projected frontal area. In fluid dynamics, the drag coefficient (commonly denoted as: , or ) is a dimensionless quantity that is used to quantify the drag or resistance of an object in a fluid environment, such as air or water.
Houston Raceway Park has permanent rest room facilities and concession buildings, located near spectator seating on both sides of the race track. Houston Raceway Park had an exclusive contract with the National Hot Rod Association to host an NHRA National Event within a 200-mile radius of the Houston metropolitan area. The event was renamed the ...
is the drag coefficient – a dimensionless coefficient related to the object's geometry and taking into account both skin friction and form drag. If the fluid is a liquid, c d {\displaystyle c_{\rm {d}}} depends on the Reynolds number ; if the fluid is a gas, c d {\displaystyle c_{\rm {d}}} depends on both the Reynolds number and the Mach number .
Some organizations that deal with Pro Modified and "Mountain Motor" Pro Stock cars (Professional Drag Racers Association) use the 1/8 mile distance, even if the tracks are 1/4 mile tracks. An early example, a 1958 Fuel dragster (technically, a rail ), on display at the California Automobile Museum Funny Car with body up.
The drag strip opened in 1955, and celebrated its 50th anniversary in 2005. The drag strip became the 2nd oldest continuously operating dragstrip in the country after Inyokern Airport closed. #1 is Redding raceway in California and opened in 53. [1] The track also is open for more dates than any other track in the United States. [1]
The facility had a quarter-mile drag strip, a 2.043 mi (3.288 km) road course, 7/10-mile kart track as well as mud racing tracks. The road course at Palm Beach International Raceway was a 2-mile, 10-turn circuit constructed of hot-mix asphalt and set on an aggregate base. It was 40 ft (12 m) wide with a 1/3-mile section measuring 80 ft (24 m).
Bandimere Speedway, also known by the NHRA as Thunder Mountain, was a quarter-mile dragstrip located just outside Morrison, Colorado and Lakewood, Colorado.It opened in 1958 and was the host to many racing events, including many NHRA Nationals events.
