Eagle HF90
The Eagle HF89 and its evolution, the Eagle HF90, is a racing car built and entered by Dan Gurney's All American Racers team, for the IMSA GT Championship. It was raced from 1989 until 1991 in IMSA's premier sports-car racing category, the GTP (Grand Touring Prototype) division. The design was also sometimes called the Eagle MkII. Background From 1983 until 1988, Dan Gurney's team entered cars in the IMSA GTO and GTU divisions, with Toyota Celicas as the basis for their cars. After claiming the driver's and constructors' championships in the GTO division in 1987 with driver Chris Cord, and a third place in the division the following year, the AAR team switched to the IMSA GTP division for 1989. The team used two types of cars; the other chassis was a TOM'S Toyota 88C car (an FIA Group C-based car). Both were powered by a turbocharged, 2.1-liter inline-4 engine producing approximately 600 horsepower, which was similar to the engines AAR used in their IMSA GTO and GTU cars. The "E ...

Grand Prix Of Miami (sports Car Racing)
The Trans-Am Series, Rolex Sports Car Series, and American Le Mans Series have all held races in the Miami area. IMSA Promoter Ralph Sanchez brought auto racing to the Miami area in 1983. A course at Bicentennial Park featured the IMSA GT Championship and the inaugural Grand Prix of Miami. A circuit was laid out on the park roads and Biscayne Boulevard. The 1983 event was a failure both competitively and financially. A severe rainstorm flooded the circuit, and stopped the race after less than one-sixth of the distance was completed. Despite not being obligated to, Sanchez decided to pay the entire purse to the competitors, absorbing a $1.3 million loss but earning great respect from the racing fraternity. A year later, the event returned, and grew into a huge success. IMSA races were held at the first Bicentennial Park from 1983 until 1985. In 1986, the event moved to a new layout, also located at Bicentennial Park. The new Bicentennial Park circuit was a semi-permanent layou ...

Mid-Ohio Sports Car Course
Mid-Ohio Sports Car Course is a road course auto racing facility located in Troy Township, Morrow County, Ohio, United States, just outside the village of Lexington. Mid-Ohio has also colloquially become a term for the entire north-central region of the state, from south of Sandusky to the north of Columbus. It hosts a number of racing series such as IndyCar, IMSA WeatherTech Sportscar Championship, and the NASCAR Xfinity Series, along with other club events such has SCCA and National Auto Sport Association. The track The track opened as a 15-turn, road circuit run clockwise. The back portion of the track allows speeds approaching . A separate starting line is located on the backstretch to allow for safer rolling starts. The regular start/finish line is located on the pit straight. In 1990 the track underwent a refurbishment. A new retaining wall was built, the entire track was resurfaced, widened and concrete was paved in the apexes of the turns to prevent asphalt deterio ...

Lime Rock Park
Lime Rock Park is a natural-terrain motorsport road racing venue located in Lakeville, Connecticut, United States, a hamlet in the town of Salisbury, in the state's northwest corner. Built in 1956, it is the nation's third oldest continuously operating road racing venue, behind Road America (1955) and Willow Springs International Motorsports Park (1953). The track is owned by Skip Barber, a former race car driver who started the Skip Barber Racing School in 1975. It was listed on the National Register of Historic Places in 2009. History The 1.53-mile Lime Rock track was originally conceived of in 1956 by Jim Vaill, who, along with John Fitch and Cornell Aeronautical Laboratory, built the track utilizing state-of-the-art road and highway safety principles of the time. The first race, a mix of G-Production class and an MG class, was held on April 28, 1957. The winner of the G-Production was Ted Sprigg in an Alfa Romeo Giulietta. The winner of the MG class was Charles Callanan in a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Timing Belt (camshaft)
In a piston engine, either a timing belt (also called a ''cambelt'') or timing chain or set of timing gears is used to synchronize the rotation of the crankshaft and the camshaft. This synchronisation ensures that the engine's valves open and close at the correct times in relation to the position of the pistons. Design In most piston engines, the camshaft(s) are mechanically connected to the crankshaft. The crankshaft drives the camshaft (via a timing belt, timing chain or pushrods), which in turn actuates the intake and exhaust valves. These valves allow the engine to inhale air (or an air/fuel mixture) and exhale the exhaust gasses. The most common devices to transfer the drive are toothed rubber belts, metal timing chains or a set of gears. The teeth of the belt/chain/gears mesh with both the crankshaft and camshaft(s), thereby synchronising their motion. In many older overhead valve engines, the camshaft is located in the block near the crankshaft, therefore a simple gear ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Horsepower
Horsepower (hp) is a unit of measurement of power, or the rate at which work is done, usually in reference to the output of engines or motors. There are many different standards and types of horsepower. Two common definitions used today are the mechanical horsepower (or imperial horsepower), which is about 745.7 watts, and the metric horsepower, which is approximately 735.5 watts. The term was adopted in the late 18th century by Scottish engineer James Watt to compare the output of steam engines with the power of draft horses. It was later expanded to include the output power of other types of piston engines, as well as turbines, electric motors and other machinery. The definition of the unit varied among geographical regions. Most countries now use the SI unit watt for measurement of power. With the implementation of the EU Directive 80/181/EEC on 1 January 2010, the use of horsepower in the EU is permitted only as a supplementary unit. History The development of the stea ...

Inline-4
A straight-four engine (also called an inline-four) is a four-cylinder piston engine where cylinders are arranged in a line along a common crankshaft. The vast majority of automotive four-cylinder engines use a straight-four layout (with the exceptions of the flat-four engines produced by Subaru and Porsche) and the layout is also very common in motorcycles and other machinery. Therefore the term "four-cylinder engine" is usually synonymous with straight-four engines. When a straight-four engine is installed at an inclined angle (instead of with the cylinders oriented vertically), it is sometimes called a slant-four. Between 2005 and 2008, the proportion of new vehicles sold in the United States with four-cylinder engines rose from 30% to 47%. By the 2020 model year, the share for light-duty vehicles had risen to 59%. Design A four-stroke straight-four engine always has a cylinder on its power stroke, unlike engines with fewer cylinders where there is no power stroke occu ...

Turbocharger
In an internal combustion engine, a turbocharger (often called a turbo) is a forced induction device that is powered by the flow of exhaust gases. It uses this energy to compress the intake gas, forcing more air into the engine in order to produce more power for a given displacement. The current categorisation is that a turbocharger is powered by the kinetic energy of the exhaust gasses, whereas a supercharger is mechanically powered (usually by a belt from the engine's crankshaft). However, up until the mid-20th century, a turbocharger was called a "turbosupercharger" and was considered a type of supercharger. History Prior to the invention of the turbocharger, |
Group C
Group C was a category of sports car racing introduced by the FIA in 1982 and continuing until 1993, with ''Group A'' for touring cars and ''Group B'' for GTs. It was designed to replace both Group 5 special production cars (closed top touring prototypes like Porsche 935) and Group 6 two-seat racing cars (open-top sportscar prototypes like Porsche 936). Group C was used in the FIA's World Endurance Championship (1982–1985), World Sports-Prototype Championship (1986–1990), World Sportscar Championship (1991–1992) and in the European Endurance Championship (1983 only). It was also used for other sports car racing series around the globe (All Japan Sports Prototype Championship, Supercup, Interserie). The final year for the class came in 1993. Broadly similar rules were used in the North American IMSA Grand Touring Prototype series ( GTP). History The roots of the Group C category lie in both FIA Group 6 and particularly in the GTP category introduced by the ACO at ...

Toyota 88C
The Toyota 88C was a racing car entered by Toyota from 1988 to 1989. It is the successor to the Toyota 87C and the predecessor to the Toyota 88C-V. Like other Toyota-powered sports prototypes of the era, it was designed and built by Dome. The 88C is an evolution of the 87C, both models sharing the same chassis number designation. The 88Cs competed in the All Japan Sports Prototype Championship, the World Sports-Prototype Championship, and the North American Camel GT Championship. Racing history All Japan Sports Prototype Championship The 88C made its debut in the 1988 All Japan Sports Prototype Championship, with a two-cars program fielded by Toyota Team Tom's achieving two fifth places as best results (Suzuka 500 km and Suzuka 1000 km). Le Mans Two 88Cs were entered by Toyota Team Tom's at the 1988 24 Hours of Le Mans. Both cars completed the event with the car of drivers Geoff Lees, Masanori Sekiya, and Kaoru Hoshino finishing in 12th, while the second car wa ...

TOM'S
is a factory supported racing team and tuner of Toyota and Lexus vehicles. The name stands for Tachi Oiwa Motor Sport. Their head office is located in Tokyo, Japan. They are currently heavily involved with Super GT, Super Formula and Super Formula Lights. TOM'S creates aftermarket parts for current Toyota vehicles, and have also created their own special edition of certain current Lexus models. History TOM'S stands for Tachi Oiwa Motor Sports. As cited in the TOM'S English website, TOM'S was established in 1974 by Nobuhide Tachi and Kiyoshi Oiwa. Despite an oil crisis at the time, the two were able to show productive results and a healthy development of motorsports for Toyota. With the support of Toyota, TOM'S went into business in 1974. In 1975 the Toyota Motor Corporation officially recognized TOM'S as an authorized tuning shop. In 1978, the firm opened a garage in the Tama area of Tokyo.

Toyota Celica
The is an automobile produced by Toyota from 1970 until 2006. The Celica name derives from the Latin word '' coelica'' meaning 'heavenly' or 'celestial'. In Japan, the Celica was exclusive to the ''Toyota Corolla Store'' dealer chain. Produced across seven generations, the Celica was powered by various four-cylinder engines, and bodystyles included convertibles, liftbacks, coupés and notchback coupés. In 1973, Toyota coined the term ''Liftback'' to describe the Celica fastback hatchback, and used the name ''Liftback GT'' for the North American market. Like the Ford Mustang, the Celica concept was to create a sports car by attaching a coupe body to the chassis and mechanicals from a high volume sedan, in this case the Toyota Carina. However, some journalists thought it was based on the Corona due to some shared mechanical parts. The first three generations of North American market Celicas were powered by variants of Toyota's R series engine. In August 1985, the car's ...
