TCR Touring Car
A TCR Touring Car is a touring car specification, first introduced in 2014 and is now employed by a multitude of series worldwide. All TCR Touring Cars are front-wheel drive cars based on 4 or 5 door production vehicles, and are powered by 1.75 to 2.0 litre turbocharged engines. While the bodyshell and suspension layout of the production vehicle is retained in a TCR car, and many models use a production gearbox, certain accommodations are made for the stresses of the racetrack including upgraded brakes and aerodynamics. Competition vehicles are subject to Balance of Performance (or BoP) adjustments to ensure close racing between different vehicles. History The project to develop the TCR specification was spearheaded by former World Touring Car Championship manager Marcello Lotti. All TCR cars have a common forefather; the SEAT León Cup Racer racing car which was introduced as successor to the SEAT León Supercopa used in several successful single-make series. The 2.0L engine ...

GT4 European Series
The GT4 European Series is a sports car racing, sports car championship created and organised by SRO Motorsports Group. It is a pro/am championship which followed a formula similar to the FIA GT3 European Championship, which was itself derived from the FIA GT Championship which utilized the GT1 and GT2 classes. The GT4 class cars are the least powerful of the four classes, yet are equalised in order to allow driving skill to become key. History Following the successful introduction of the FIA GT3 European Championship in 2006, the formula was expanded to include usage by other nationally based professional championships such as the British GT Championship, Belcar, Australian GT Championship and German ADAC GT Masters. While the FIA GT3 European Championship continues, the SRO felt that a true amateur championship was needed in order to complement GT3 which allowed a certain level of professional driver to compete. Many national series also adopted the GT4 regulations as a lower cl ...

Forced Induction
In an internal combustion engine, forced induction is where turbocharging or supercharging is used to increase the density of the intake air. Engines without forced induction are classified as naturally aspirated. Operating principle Overview Forced induction is often used to increase the power output of an engine. This is achieved by compressing the intake air, to increase the mass of the air-fuel mixture present within the combustion chamber. A naturally aspirated engine is limited to a maximum intake air pressure equal to its surrounding atmosphere; however a forced induction engine produces "boost", whereby the air pressure is higher than the surrounding atmosphere. Since the density of air increases with pressure, this allows a greater mass of air to enter the combustion chamber. Theoretically, the vapour power cycle analysis of the second law of thermodynamics would suggest that increasing the mean effective pressure within the combustion chamber would also increase ...
