Dirt Track Racing
Dirt track racing is a form of motorsport held on clay or dirt surfaced oval race tracks often used for thoroughbred horse racing. 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. Two different types of race cars dominate — open wheel racers in the Northeast and West and stock cars in the Midwest and South. 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 nation. The sport is also popular in Australia, New Zealand, Canada, South Africa and the United Kingdom. Racetrack 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. ...

Chrysler LA Engine
The LA engines are a family of pushrod OHV small block 90° V-configured gasoline engines built by Chrysler Corporation. It was factory-installed in passenger vehicles, trucks and vans, commercial vehicles, marine and industrial applications from 1964 through 1991 (318) & 1992 (360). The combustion chambers are wedge-shaped, rather than the polyspherical combustion chambers in the predecessor '' A engine'' or the hemispherical combustion chambers in the Chrysler Hemi engine. LA engines have the same bore spacing as the A engines. LA engines were made at Chrysler's Mound Road Engine plant in Detroit, Michigan, as well as plants in Canada and Mexico. The "LA" stands for "Light A", as the 1956 - 1967 "A" engine it was closely based on and shares many parts with was nearly 50 pounds heavier. The "LA" and "A" production overlapped from 1964 - 1966 in the US and through 1967 in export vehicles when the "A" 318 engine was phased out. Willem Weertman, who later became Chief Engi ...

Spoiler (automotive)
A spoiler is an automotive aerodynamic device whose intended design function is to 'spoil' unfavorable air movement across a body of a vehicle in motion, usually described as turbulence or drag. Spoilers on the front of a vehicle are often called air dams. Spoilers are often fitted to race and high-performance sports cars, although they have become common on passenger vehicles as well. Some spoilers are added to cars primarily for styling purposes and have either little aerodynamic benefit or even make the aerodynamics worse. The term "spoiler" is often mistakenly used interchangeably with "wing". An automotive wing is a device whose intended design is to generate downforce as air passes around it, not simply disrupt existing airflow patterns. As such, rather than decreasing drag, automotive wings actually increase drag. Operation Since spoiler is a term describing an application, the operation of a spoiler varies depending on the particular effect it is trying to spoil. ...

Cylinder Head
In an internal combustion engine, the cylinder head (often abbreviated to simply "head") sits above the cylinder (engine), cylinders and forms the roof of the combustion chamber. In sidevalve engines, the head is a simple sheet of metal; whereas in more modern overhead valve engine, overhead valve and overhead camshaft engine, overhead camshaft engines, the cylinder head is a more complicated block often containing inlet and exhaust passages, coolant passages, Poppet_valve#Usage_in_internal_combustion_engines, valves, camshafts, spark plugs and Fuel_injection#Direct_injection, fuel injectors. Most straight engines have a single cylinder head shared by all of the cylinders and most V engines have two cylinder heads (one per bank of cylinders). Design A summary of engine designs is shown below, in chronological order for automobile usage. Sidevalve engines In a flathead engine, flathead (''sidevalve'') engine, all of the valvetrain components are cam-in-block, contained wi ...

Cylinder Block
In an internal combustion engine, the engine block is the structure which contains the cylinders and other components. In an early automotive engine, the engine block consisted of just the cylinder block, to which a separate crankcase was attached. Modern engine blocks typically have the crankcase integrated with the cylinder block as a single component. Engine blocks often also include elements such as coolant passages and oil galleries. The term "cylinder block" is often used interchangeably with "engine block", although technically, the block of a modern engine (i.e. multiple cylinders integrated with another component) would be classified as a monobloc. __TOC__ Construction The main structure of an engine typically consists of the cylinders, coolant passages, oil galleries, crankcase, and cylinder head(s). The first production engines of the 1880s to 1920s usually used separate components for each of these elements, which were bolted together during engine assembly ...

Engine Displacement
Engine displacement is the measure of the cylinder volume swept by all of the pistons of a piston engine, excluding the combustion chambers. It is commonly used as an expression of an engine's size, and by extension as a loose indicator of the power an engine might be capable of producing and the amount of fuel it should be expected to consume. For this reason displacement is one of the measures often used in advertising, as well as regulating, motor vehicles. It is usually expressed using the metric units of cubic centimetres (cc or cm3, equivalent to millilitres) or litres (l or L), orparticularly in the United States cubic inches (CID, cu in, or in3). Definition The overall displacement for a typical reciprocating piston engine is calculated by multiplying together three values; the distance travelled by the piston (the stroke length), the circular area of the cylinder, and the number of cylinders in the whole engine. The formula is: : \text = \text \times \frac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Motor
An engine or motor is a machine designed to convert one or more forms of energy into mechanical energy. Available energy sources include potential energy (e.g. energy of the Earth's gravitational field as exploited in hydroelectric power generation), heat energy (e.g. geothermal), chemical energy, electric potential and nuclear energy (from nuclear fission or nuclear fusion). Many of these processes generate heat as an intermediate energy form, so heat engines have special importance. Some natural processes, such as atmospheric convection cells convert environmental heat into motion (e.g. in the form of rising air currents). Mechanical energy is of particular importance in transportation, but also plays a role in many industrial processes such as cutting, grinding, crushing, and mixing. Mechanical heat engines convert heat into work via various thermodynamic processes. The internal combustion engine is perhaps the most common example of a mechanical heat engine, in wh ...

Late Model
A late model car is a car which has been recently designed or manufactured, often the latest model. (An early model car or classic car is a car old enough to be of historical interest; there is no usual intermediate term.) The precise definition of "late model" varies. Racing Late model race cars are the highest class of local stock car racing vehicles at many race tracks in the United States and Canada. Some regional and lower national-level series race in late models. Varieties of late models (ranked from the highest vehicle performance to lowest) include super late models, late models, and limited late models. Some series require crate motors to be utilized by racecars under their sanction, which often utilize GM 604 engines. Vehicles raced on dirt tracks are significantly different from vehicles raced on asphalt. Super late models are the premier divisions of asphalt short track racing in the United States and Canada. They typically feature engines with upwards of , Amer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United Midwestern Promoters
United Midwestern Promoters (UMP) is a short track motor racing sanctioning body in the United States that sanctions short track racing on dirt race tracks from 1/5 mile (0.3 km) in length to in length. UMP currently sanctions eight different racing divisions on over 100 tracks in 19 states and one province in Canada. UMP was created in 1984 by Bob Memmer. Classes UMP began by sanctioning UMP Late Model and UMP Modified cars. UMP Modified cars are quite similar in appearance to IMCA Modified cars. UMP reorganized their class system in 2007 by sanctioning one new class. The revised class system included: UMP Super Late Models, UMP Modifieds, UMP Pro(Crate) Late Models, UMP Limited Modifieds, UMP Sportsman, and UMP Street Stocks, UMP Factory Stocks,& UMP 4 Cylinders. UMP announced in late November 2007 that the sanctioning body will add one more class: UMP Pro (Crate) Late Model.
