Dirt track racing is a form of motorsport held on clay or dirt surfaced banked oval racetracks. Dirt track racing started in the United States before World War I and became widespread during the 1920s and 1930s using both automobiles and motorcycles, spreading throughout Japan and often running on horse racing tracks. There are a myriad of types of race cars used, from open wheel Sprint cars and Modifieds to stock cars. While open wheel race cars are purpose-built racing vehicles, stock cars (also known as fendered cars) can be either purpose-built race cars or street vehicles that have been modified to varying degrees. There are hundreds of local and regional racetracks throughout the United States and also throughout Japan. The sport is also popular in Canada , Mexico , Argentina , Brazil , Chile , Australia , New Zealand , South Africa and the United Kingdom .
51-705: The Motordrome , also known as the Olympic Park Speedway , the Melbourne Speedway or the Victorian Speedway , was a former speedway and Australian rules football ground located approximately on the site of the present day Melbourne Rectangular Stadium in Olympic Park in Melbourne , Victoria . The ground was primarily a speedway track, but also hosted football matches. Melbourne Carnivals Pty. Ltd,
102-420: A National and/or Regional touring racing association to schedule a sanctioned event. The racers in these events earn points for ranking within the series and sometimes the tracks points. The associations also usually require a guaranteed purse from the tracks of sanctioned events. Some tracks also have a "run-what-you-brung" contest usually toward the beginning of the season. Spectator racing pits two drivers from
153-566: A company established in 1923 by Jack Campbell and Jim DuFrocq, developed and leased a large site known as the Amateur Sports Ground from the Crown with the help of local entrepreneur John Wren . On the site, the Motordrome was constructed. The stadium contained a grassed oval suitable for football, set inside a saucer-shaped concrete oval track suitable for motor racing; the track was a third of
204-424: A decade and all tracks paved over eventually reverted to their former surfaces. Each racetrack or sponsoring organization maintains a rule book outlining each class of race car which includes dimensions, engine size, equipment requirements and prohibitions. The requirements for each class are usually coordinated with multiple tracks to allow for the widest available venue for each type of car. This coordination allows
255-840: A few original stock parts and may be nearly as fast as late model race cars. Most cars have their glass windshields removed and their interiors stripped out. The original seat may be allowed to be used in the lowest classes, but a racing seat and roll cage is required to be installed in higher divisions. Other safety and performance features are added to higher division cars. The engines in lower divisions are completely stock, and higher divisions are highly modified and enhanced. Most modified production cars use full exhaust systems. Engines vary from unmodified 4 cylinders to highly modified V8. Cars in lower divisions use stock tires, and higher division cars use purpose-built specified racing tires. Common names of modified production car divisions: These are Full-bodied cars with very few changes allowed from
306-428: A grader, a cultivator or rototiller, 2 types of rollers and a watering truck, although the process varies at different dirt tracks around the world. After an event, a track's rutted surface is first graded and smoothed back into the contours of the track's layout. then further smooth and tamp loose soil shoveled into any soft spots. The freshly smoothed track surface is then aerated with a cultivator or rototiller to loosen
357-692: A late model stock. Crate late models use Chevrolet small-block engine engines that have been sealed with a special tag. Typical motors include the GM 602 and GM 604 engines. Recently the GM CT525 crate has been a popular choice of racers and some after-market Ford motors have surfaced in competition. Crate engines are sealed at the intake manifold, cylinder head , front cover, and oil pan with special twist off bolts. Crate engines must not be altered, modified, or changed in any way from factory specifications. Crate late models have three primarily Southern region touring series:
408-442: A mile long and banked at a 46° angle. Although Melbourne Carnivals originally had visions for the stadium to accommodate 100,000 spectators, it was ultimately built to accommodate around 32,000. The Motordrome was opened on 29 November 1924, and 32,000 spectators attended the inaugural race meeting. In 1933, the ageing concrete surface of the motor racing track was no longer suitable for the higher powered vehicles which used it, so it
459-426: A number of classes, and many tracks offer both open wheel and stock car racing. There are a wide variety of event formats. These races are 2-5 laps for drivers to get an understanding of the track conditions and the set up of their race cars. They are at the very start of the night before qualifying and the heat races. A qualifying session happens before the start of the event. The Lucas Oil Dirt Late Model Series and
510-437: A set number of points for where they finish, 1st-59 2nd-57 and so forth the lower they finish. To add to the points the driver gets for finishing, the driver also gets 1.5 points for each car they pass. They will then usually take the top 16 drivers with the highest total number of points and line up the A feature. There may be a semi-feature where unqualified racers may race their way into the remaining open starting positions in
561-591: A significant off-field impact on football during the 1920s and 1930s. When the venue was first established in 1924, the Victorian Football League was very keen for strategic reasons to control it. Melbourne Carnivals had offered to lease the ground to the new Public Service Football Club if it were admitted to the League in 1925. This offer became the trigger for off-field negotiations which ultimately saw Footscray , Hawthorn and North Melbourne admitted to

#1732868918221612-412: A walk. Dirt track racing A dirt track's racing surface may be composed of any soil, although most seasoned dirt racers probably consider a moist, properly prepared clay oval their favorite dirt racing surface. Preparing a dirt track correctly for racing is both a traditional learned craft as well as a long and complex job requiring hours of work. Typical machines used in track preparation include
663-555: Is being run. The racetrack dictates what type of late model is raced, but most fall into one of these categories: Current dirt super late models feature steel constructed tube frame chassis with aluminum bodies that give them the sleek aerodynamic appearance of a stock race car but there is nothing stock about these 2300 pound machines. The cars are powered by an 850 horsepower (630 kW) motor than can turn in excess of 9,000 rpm. The engines are based on V-8 Chevrolet, Chrysler, and Ford power plants. These cars are considered to be
714-573: Is generally acknowledged that the first Speedcar race in Australia took place at the speedway in 1934. In 1936/37, the speedway also saw two Motorcycle speedway test matches between the Australians , including future ( 1938 ) Speedway World Champion Bluey Wilkinson , taking on the visiting Americans who included the 1937 World Champion Jack Milne and his younger brother Cordy , as well as Wilbur Lamoreaux who would finish second behind Milne in
765-429: Is held for each division. The top cars from the event compete in the race. The starting positions may be determined by the season's point standings, or by a combination of the heat/qualifying speed/trophy dash/semi-feature finishing positions. It is usually the longest race in the program and depending upon the division it may range from 10 laps to 50 laps. Points, a trophy, and frequently a purse are generally awarded, with
816-879: Is much more expensive. To get the frame (chassis) and parts all new without the transmission and motor is around 20,000 to 30,000 dollars depending on the quality and from which manufacturer the chassis comes. The top manufacturers around the country include Rocket, Sweet-Bloomquist, Club 29, Longhorn, MB Customs, Black Diamond Racecars, GRT, Warrior, Barry Wright Racecars, Rayburn, MasterSbilt, Kryptonite, Domination chassis, and Schwartz Race Cars. The engines for these cars are around 850 horsepower and can cost up to 40,000 dollars. Motor builders include Hatfield Racing, Jay Dickens Racing Engines, Durham Racing Engines, Cornett Racing Engines, Sheered Engine Development, Gaerte Racing Engines, Clements Racing Engines, Custom Racing Engines, Vic Hill Racing Engines and Pro Power Engines. Most racing series and special events offer different motor options with
867-529: The 1920s and 1930s. Most oval track speedways are similar to those in the US for car racing such as sprint cars , speedcars (midgets) and sedans, with most tracks generally around 1 ⁄ 4 to 1 ⁄ 3 mile (400 to 540 m) in length. Most tracks have a clay surface, though some use dolomite , dolomite and clay mix or even sand and clay mix. During the 1970s and early 1980s, a small number of tracks were paved with asphalt, though this phase only lasted about
918-613: The 1931 season, the VFL and the Grounds Management Association (which represented the operators of most of the VFL grounds) entered a dispute over the use of the grounds for football matches, covering financial arrangements and the demarcation between the football and cricket seasons. During the dispute, the VFL arranged for the Motordrome, as well as the Exhibition Oval , to host twelve games which were to be transferred away from
969-582: The 1937 World Final at the Empire Stadium in London (Cordy Milne would finish third). Australia won the first test 31–23 on 19 December 1936, and won the third test 30–24 on 23 January 1937 (the second test, won 29-24 by Australia, was held at the Sydney Showground on 28 December). Although not much top-level football was played on the Motordrome, its presence as a high capacity centrally-located ground had
1020-425: The A feature event. This race is called the last chance qualifier or B feature. The cars who did not make the A feature through the heat race or qualifying session get one more chance to qualify for the A feature through the B feature. The B length is anywhere up to circa 20 laps. Depending on how many B's there are determines how many transfer to the A, anywhere up to circa 6 will transfer. If a driver transfers through
1071-418: The B, they will start behind the drivers who made it through the heats / qualifying position. At selected other races with a larger car count, there may be more "alphabet soup" features (C, D, E, F, etc.). In those cases the drivers in the lower feature race will race with a certain number who advances to the next higher feature (e.g. top two in the F advance to the E, etc.). The A feature or main feature race
SECTION 20
#17328689182211122-649: The Durrence Layne Dirt Late Model Series, the United Crate Racing Alliance and the Fastrak Crate Late Model Series. There are hundreds of additional unsanctioned regional and national special events run throughout the year. Dirt and grass track bikes have capacities of 250, 350, 500 and in the solo classes and can reach speeds of up to 80 mph (130 km/h) on the straights and with no brakes fitted to
1173-455: The U.S. are 1 ⁄ 2 mile (800 m), 3 ⁄ 8 mile (600 m), 1 ⁄ 3 mile (540 m), 1 ⁄ 4 mile (400 m), and 1 ⁄ 8 mile (200 m). With the longer tracks, the race cars achieve higher speeds up to 160 mph (260 km/h) and the intervals between cars increase. This decreases the chance of crashes but increases the damage and chance of injury when cars do crash. In Great Britain
1224-477: The VFL , but saw the VFL fail to secure the use of the Motordrome. There had been proposals for the Richmond Football Club to move to the venue, or for it to be used as a neutral venue to which each club moved one or two of its home matches each year; however, these proposals fell through. The Victorian Football Association went on to play its finals matches at the venue in 1925, 1926 and 1927. Prior to
1275-512: The World of Outlaw Late Models use the qualifying system to line up their heat races. They give each driver 2 timed laps to get their times. This system is also used to line up the big crown jewel events. For most of the regional series they use the method called the "pill draw." Before the races each driver draws a number and that determines where they start in their heat race. Recently the innovation of Transponder Scoring has brought dirt track racing into
1326-422: The amount of each is determined by finishing position. The winner of the feature event is considered the winner of the event. Many tracks have special events which tends to draw a larger crowd. Occasionally, a track will sponsor a "powder-puff" race to allow women the opportunity to drive racecars for a few laps of racing. Otherwise, woman racers may compete in the same events as the men. Many tracks contract with
1377-659: The class, the cars may have wings to aid in handling at higher speeds. Open wheel cars are generally manufactured with tubular frames and a body purchased for that particular class. The wheels of these vehicles are not protected by fenders; they are exposed or "open". Classes include: Open wheel sanctioning bodies include: Popular chassis manufacturers around the country for winged sprint cars are Eagle, Maxim, J&J, Triple X, and GF1. There are also several engine builders that build both 410ci and 360ci engines for traveling sprint car teams. Speedway, Kistler, Gaerte, Wesmar, Shaver, Don Ott Racing Engines, and Fisher Racing Engines are
1428-621: The driver and passenger working together to obtain the best grip and speed around the corners. Many obsolete race vehicles that were left in barns to rust are being restored to their former glory. The restored race vehicles are being displayed at car shows and sometimes raced. Cars that compete in vintage racing events are from the late 19th century to historic cars from a few years ago. There are more than 170 racing events in North America, and thousands of other vintage events sanctioned by hundreds of clubs. The typical race program usually involves
1479-475: The drivers to compete at many different racetracks, increase competitors' chances of winning, and lets racing associations develop a series of race events that promote fan interest. Many tracks support two types of racing in their programs, open wheel cars and stock cars. Both types range from large and powerful V8 engines to small yet still powerful, four-cylinder engines. Some of the smaller open wheel race cars have classes for single-cylinder engines. Depending on
1530-459: The drivers. Super Stock cars are very similar to Late Models and can be built from the ground up by the racers. They have limited engines and other restricted items that keep them from being full blown Late Models, but they are much more powerful than the Street Stocks and are an intermediate class between Street Stock, Modifieds and Late Models. The bodies are aftermarket or made by the racers in
1581-541: The end of 1935 between VFA Grand Finalists Yarraville and Camberwell , and at the end of 1936 between combined teams representing the VFL and VFA. School and junior football was regularly played on the venue. On 11 December 1926, the venue hosted a shambolic ostrich racing event. A full program of races was scheduled, but the event was cancelled after three farcical attempts at races – in which startled ostriches ridden by inanimate jockeys ran in opposite directions, and ostriches attached to sulkies failed to break out of

1632-492: The factory except for the roll cage. These would also be considered Pure Stock, but not full sized. These are also Full-bodied cars but can have changes to the frame, engines, tires and some changes to the suspension. They have to have bodies shaped like the actual cars that are used on the street direct from the factory. As with the Pure Stocks cars, all are required to have a full set of Roll Cages and safety harnesses to protect
1683-454: The factory models sold for general use on the streets. Changes can be limited to a certain type of tire, making some parts of the car stronger to withstand the punishment of racing and so forth. All cars used on the race track are required to have a full set of Roll Cages and safety harnesses to protect the drivers. Some tracks have what they call Hornets which are smaller unibody cars with 4-cylinder engines, that must be pretty much as they left
1734-409: The feature event. In a race where they qualify to determine their starting position for the heat race they use a "heads up" system. This system is where there is a predetermined set of cars that go to the A feature from the heat race, usually either the top 3 or 4. In a race where they use the pill draw to line up the heat races they use a method called passing points. In this system a driver receives
1785-496: The general shape of the brand being represented (Chevrolet, Ford, Dodge, etc.). These cars are automobiles just as driven on the street; including the original interiors. The engines may be modified as allowed under different rules: Saloon These are stock cars custom built for racing, usually with welded tubular frames and custom built or purchased bodies. The most popular type of dirt full-bodied stock cars are late models. They are categorized depending on what track and series that
1836-459: The ground each year, as well as playing the finals there. This caused a massive dispute with the local councils which owned the VFA's suburban grounds, and it culminated in seven of the VFA's twelve clubs being kicked out of their local grounds until the agreement was rescinded, almost ruining the 1934 VFA season and potentially forcing those clubs to disband or secede en masse from the VFA. The agreement
1887-475: The grounds involved in the dispute, but the dispute was ultimately resolved through arbitration in March and the games were transferred back to their original grounds. Then in 1932, the VFA signed a deal to use the Motordrome as a neutral central venue from 1933 until 1940. Under the agreement, the VFA would play one match at the ground each weekend during the season, with each club moving one or two of its home games to
1938-456: The internet immediate post "live" scoring and timing of events (Race Monitor). Preliminary races for each class, called heat races, frequently open the schedule. The heat races may determine the starting race position in the main events and usually earn season championship points. The heat races are shorter than the feature races, and not as many cars race in each heat, from 8 to 12 laps for a heat race. There are numerous formats for qualifying for
1989-551: The machine. The American Grand National dirt track championship uses motorcycles of up to 750 cc capacities and can reach speeds of up to 130 mph (210 km/h). There are three sidecar classes. The continental class has a 500 cc single-cylinder engine, also in Great Britain there are left- and right-handed sidecar machines with the engines up to 1000 cc. Sidecar races are some of the most exciting in Grass Track sport, with
2040-425: The major automakers with certain modifications as allowed for each class. There are several general types: These cars are modified manufactured automobiles. There is a high degree of variability between classes of modified cars. The lowest divisions of modified production cars may be completely stock except for having their interior or windshields removed. The highest divisions of modified production cars may have only
2091-723: The more popular engine builders. Modified cars are a hybrid of open wheel cars and stock cars. This class of car has the racing characteristics of a stock car. The rear wheels are covered by fenders, but the front wheels are left exposed. There are sanctioning bodies that control the rules for this class at most tracks. Each sanctioning body has their own set of guidelines provided in an annual rule book and their own registration fees. Sanctioning bodies include: Full-bodied cars, sometimes referred to as stock cars, are vehicles that, unlike open-wheel cars, have fenders covering all wheels. Full-bodied cars can vary from full tube frame chassis and aluminum bodied late models to automobiles manufactured by

2142-418: The most sophisticated cars in dirt racing. They hit speeds well over 100 mph (160 km/h) and slide around the dirt corners. They are raced on dirt tracks throughout the country anywhere from 1/5 to one mile. The expense for these cars is significant. The cost for one complete race-ready late model is around $ 70,000. There is also cheaper equipment and parts that can be purchased, but staying competitive
2193-612: The now-compacted upper layer and assist with greater water penetration for a moister track on race day. Watering is repeated as necessary according to climate, location and soil composition. Using offset boom nozzles to on water trucks will avoid mashing aerated soil. A dirt track should be rolled and watered as required on race morning with a final light watering, just prior to wheel-packing. Outdoor dirt tracks are typically aerated 12" deep. Nearly all tracks are oval and less than 1-mile (1.6 km) in length with most being 1 ⁄ 2 mile (800 m) or less. The most common increments in
2244-421: The oval tracks are normally on grass with lengths of 400 meters (¼ mile) to 800 meters (½ mile). The races consist of several four lap qualifying heats that eliminate slower drivers. Then there is a final race featuring the fastest competitors. In mainland Europe, long tracks can be grass, sand or cinder, and can be up to 1-kilometer (0.62 mi) long. Dirt track racing in Australia has a history dating back to
2295-468: The stands who, after signing waivers, can run their personal automobiles against each other in a one-on-one 1 or 2 lap shootout. Dirt tracks tend to be somewhat more makeshift and more versatile than asphalt pavements, and can be converted for use in other motorsports. For instance, Little Valley Speedway in Little Valley, New York is a half-mile dirt track that can be converted into a figure 8 track ,
2346-426: The use of different total vehicle weights to create an even playing field: Limited late models and late model stocks have the same body rules as super late models. The main difference in the two classes is the motor rules. Engine limitations typically include maximum engine displacement size, certain required cylinder head angles, maximum compression ratios, and maximum carburetor size. Suspension rules typically forbid
2397-519: The use of expensive canister shocks. Tire choice is also typically limited to a certain tire such as the Hoosier D55 spec tire. Late model stocks have the same body rules as super late models and limited late models. This class typically has even more limited engine rules. Typical late model stock engine requirements: Many different tracks and sanctioning bodies have variations on these rules of what constitutes an open late model, limited late model and
2448-541: The venue occurred during the early part of 1932 , when Melbourne played three home matches there because the Melbourne Cricket Ground was being resurfaced. In the 1935 pre-season, the venue staged a night match under electric floodlights between 1934 VFL Grand Finalists Richmond and South Melbourne . The players had some visibility problems, mostly with depth perception, but the match attracted 25,000 spectators. Further exhibition night matches were played at
2499-620: Was chosen because the former name 'Amateur Sports Ground' no longer reflected the class and type of sport which was now played on the grounds. The complex was sold after the Second World War and began to be converted into the Olympic Park Stadium used during the 1956 Olympics . During the time of the Great Depression the ground regularly drew in crowds of more than 30,000 to watch speedway, motorcycle and sidecar racing. It
2550-552: Was demolished and replaced with a dirt track which continued to be used for motor racing. In the same year, the Amateur Sports Ground was renamed Olympic Park , and the name was generally used for both the former Motordrome stadium, and the wider park in which it was situated. The name change had no connection to the Olympic Games – Melbourne was not selected as the host of the 1956 Summer Olympics until 1949 – and rather
2601-579: Was rescinded shortly before the season began. The Richmond Football Club formally announced its intentions to move its home base from the Punt Road Oval to Olympic Park prior to the 1936 season, owing mostly to an ongoing dispute with the Richmond Cricket Club . Richmond's proposal to move was ultimately voted down by the VFL, but only by the casting vote of League president William McClelland . The only VFL premiership football ever played at
