Junior Dragster
The Junior Dragster or Jr Dragster is a scaled-down version of the top fuel dragster. The cars were developed in New Zealand in 1988, with classes developed by the New Zealand Hot Rod Association. The National Hot Rod Association in the USA began sanctioning the class in 1991, with the JDRL (Junior Drag Racing League). The JDRL is a division of the NHRA, which consists of two different dragster classes, traditional Jr. Dragster having a wheelbase between 90 and 150 inches and a single-cylinder, five brake horsepower Briggs & Stratton engine, and the larger Jr. Comp dragster being 150-190 inches in wheelbase and using a motorcycle or personal watercraft engine. Junior drag racers may choose to participate in programs run by the NHRA, IHRA and the Australian National Drag Racing Association NDRA or at an unsanctioned facility. Drivers may be male or female and must be at least five years of age to test, and six years to compete, and be no older than 20 years on December 31 o ...

International Hot Rod Association
The International Hot Rod Association (IHRA) is the second-largest drag racing sanctioning body after the National Hot Rod Association (NHRA). The Carrier Era 1971-1987 The IHRA was formed in November 1970 by businessman Larry Carrier. Throughout this period the organization was operated primarily in the south-eastern United States from its headquarters in Bristol, Tennessee. The IHRA initially followed the NHRA's professional class structure of Top Fuel, Funny Car and Pro Stock until the 1984 season when it decided to drop the premier Top Fuel category, an arrangement that only lasted three years before the class was reinstated for the 1987 season. Carrier is also credited with initiating drag racing's long-term sponsorship association with the R.J. Reynolds Tobacco Company's Winston brand, which has ended. 1988-98 IHRA headquarters briefly moved to Waco, Texas in 1988 after it was purchased by Texan racer and track operator Billy Meyer who made many changes to the organ ...

NHRA Conference Finals
The National Hot Rod Association (NHRA) is a drag racing governing body, which sets rules in drag racing and hosts events all over the United States and Canada. With over 40,000 drivers in its rosters, the NHRA claims to be the largest motorsports sanctioning body in the world. The association was founded by Wally Parks in 1951 in California to provide a governing body to organize and promote the sport of drag racing. NHRA's first Nationals was held in 1955, in Great Bend, Kansas. The NHRA Camping World Drag Racing Series, the national event series which comprises 24 races each year, is the premier series in drag racing that brings together the best drag racers from across North America and the world. The NHRA U.S. Nationals are now held at Lucas Oil Raceway in Brownsburg, Indiana and are officially called the U.S. Nationals. Winners of national events are awarded a trophy statue in honor of founder Wally Parks. The trophy is commonly referred to by its nickname, “Wally� ...

Slide Valve
The slide valve is a rectilinear valve used to control the admission of steam into and emission of exhaust from the cylinder of a steam engine. Use In the 19th century, most steam locomotives used slide valves to control the flow of steam into and out of the cylinders. In the 20th century, slide valves were gradually superseded by piston valves, particularly in engines using superheated steam. There were two reasons for this: * With piston valves, the steam passages can be made shorter. This reduces resistance to the flow of steam and improves efficiency. * It is difficult to lubricate slide valves adequately in the presence of superheated steam. Murdoch's D slide valve The D slide valve, or more specifically Long D slide valve, is a form of slide valve, invented by William Murdoch and patented in 1799. It is named after the hollow central D-sectioned piston. This valve worked by "connecting the upper and lower valves so as to be worked by one rod or spindle, and in mak ...

Personal Watercraft
A personal watercraft (PWC), also called water scooter or jet ski, is a recreational watercraft that a rider sits or stands on, not within, as in a boat. PWCs have two style categories, first and most popular being a runabout or "sit down" where the rider uses the watercraft mainly sitting down, and the watercraft typically holds two or more people. The second style is a "stand-up", where the rider uses the watercraft standing up. The stand-up styles are built for one rider and are used more for doing tricks, racing, and use in competitions. Both styles have an inboard engine driving a pump-jet that has a screw-shaped impeller to create thrust for propulsion and steering. Most are designed for two or three people, though four-passenger models exist. Many of today's models are built for more extended use and have the fuel capacity to make long cruises, in some cases even beyond 100 miles (161 km). Personal watercraft are often referred by the trademarked brand names of per ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Top Fuel
Top Fuel is a type of drag racing whose dragsters are the quickest accelerating racing cars in the world and the fastest sanctioned category of drag racing, with the fastest competitors reaching speeds of and finishing the runs in 3.62 seconds. A top fuel dragster accelerates from a standstill to in as little as 0.8 seconds (less than one third the time required by a production Porsche 911 Turbo to reach ) and can exceed in just . This subjects the driver to an average acceleration of about over the duration of the race and with a peak of over . Because of the speeds, this class exclusively races to only a distance, and not the traditional one-fourth of a statute mile, or . The rule was changed in 2008 by the National Hot Rod Association following the fatal crash of Funny Car driver Scott Kalitta during a qualifying session at Old Bridge Township Raceway Park in Englishtown, New Jersey. The shortening of the distance was used by the FIA at some tracks, and as of 2012 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wheelbase
In both road and rail vehicles, the wheelbase is the horizontal distance between the centers of the front and rear wheels. For road vehicles with more than two axles (e.g. some trucks), the wheelbase is the distance between the steering (front) axle and the centerpoint of the driving axle group. In the case of a tri-axle truck, the wheelbase would be the distance between the steering axle and a point midway between the two rear axles. Vehicles The wheelbase of a vehicle equals the distance between its front and rear wheels. At equilibrium, the total torque of the forces acting on a vehicle is zero. Therefore, the wheelbase is related to the force on each pair of tires by the following formula: :F_f = mg :F_r = mg where F_f is the force on the front tires, F_r is the force on the rear tires, L is the wheelbase, d_r is the distance from the center of mass (CM) to the rear wheels, d_f is the distance from the center of mass to the front wheels (d_f + d_r = L), m is the mas ...

Briggs & Stratton
Briggs & Stratton Corporation is an American manufacturer of gasoline engines with headquarters in Wauwatosa, Wisconsin. Engine production averages 10 million units per year as of April 2015. The company reports that it has 13 large facilities in the U.S. and 8 more in Australia, Brazil, Canada, China, Mexico, and the Netherlands. The company's products are sold in over 100 countries across the globe. History In 1908, inventor Stephen Foster Briggs and investor Harold M. Stratton started an informal partnership to capitalize on the growing automobile industry. Eventually Briggs and Stratton settled on manufacturing automotive components and small gasoline engines. In 1919 Briggs & Stratton purchased the manufacturing rights for a small, simple two-seat vehicle with a gasoline engine called the Smith Flyer from the A.O. Smith Company in Milwaukee. The Flyer had a small gasoline engine mounted on a fifth wheel, or motor wheel. Briggs & Stratton made engine improvements ...
