Introduction
The Toyota GR Supra is a sports car that was produced by Japanese manufacturer Toyota from 1978 to 2002. The first two generations of the Supra were sold in the Japanese domestic market (JDM) under the chassis code “MA70” and “JZA70”, respectively. The third generation of the Supra was sold in Japan as the “A70” from 1986 to 1992 and as the “JZA70” from 1992 to 2002; it also was sold internationally as the “Supra”.
The fourth generation of the Supra was introduced in 2019. It is based on the Toyota FT-1 concept car[1] which was presented at the Detroit Motor Show in 2014.[2][3] The fifth generation has been confirmed and it is set to be released in 2021.
The GR Supra is powered by a 3.0-litre turbocharged inline-six engine, codenamed B58B30TOY, which produces 340 hp (253 kW) and 500 N⋅m (369 lb⋅ft) of torque.[4] The engine is mated to an eight-speed automatic transmission with manual shifting mode.
What is forced induction?
In automotive engineering, forced induction is the process of delivering compressed air to the intake of an internal combustion engine. A forced induction engine uses a gas compressor to increase the pressure, temperature and density of the air. This compressed air is then introduced into the cylinders where it causes an increase in power output.
The three main types of forced induction technologies are turbocharging, supercharging and nitrous oxide injection. Each of these technologies has its own unique advantages and disadvantages.
Turbocharging
Turbocharging is a type of forced induction that uses a turbine to compress air and force it into the cylinders. Turbochargers are powered by exhaust gases, which means they do not require any external power source. turbochargers are typically more efficient than superchargers, but they can also be more expensive.
Supercharging
Supercharging is a type of forced induction that uses a belt or chain-driven pump to compress air and force it into the cylinders. Superchargers are powered by the engine’s crankshaft, which means they require an external power source. Superchargers are typically less efficient than turbochargers, but they can be less expensive.
Nitrous Oxide Injection
Nitrous oxide injection is a type of forced induction that injects nitrous oxide into the cylinders. Nitrous oxide is a compressed gas that provides oxygen for combustion. When injected into the cylinders, nitrous oxide increases power output by allowing more fuel to be burned per cycle. Nitrous oxide injection is typically less expensive than turbocharging or supercharging, but it can also be less reliable
The different types of forced induction
There are three main types of forced induction that are utilized in the Gr Supra: turbocharging, supercharging, and nitrous oxide injection. Each of these has its own benefits and drawbacks, so it’s important to understand how they work before deciding which one is right for you.
Turbocharging is by far the most popular form of forced induction, as it offers a significant power increase without adding too much weight or complexity to the engine. However, turbochargers can be somewhat temperamental and require careful tuning to prevent engine damage.
Superchargers are similar to turbochargers in that they force more air into the engine, but they are driven by a belt connected to the crankshaft instead of exhaust gas. This reduces lag time and makes them more responsive than turbochargers, but they also tend to be less efficient.
Nitrous oxide injection is the most extreme form of forced induction, as it can add a significant amount of power to an engine very quickly. However, it is also the most dangerous, as incorrect installation or tuning can easily cause engine damage.
The history of forced induction
The history of forced induction can be traced back to the late 1800s, when Gottlieb Daimler patented a device that injected air into the cylinders of a internal combustion engine. This system, known as Daimler’s air motor, was later used on diesel engines in the early 1900s. In the 1920s, European race car builders began using superchargers to increase power output. By the 1930s, all major automakers were offering cars with superchargers.
The first turbocharged production car was the 1962 Oldsmobile Jetfire, which used a turbocharger to increase power from its215-cubic-inch V8 engine. In 1970, Porsche introduced the 911 Turbo, which was powered by a 3.0-liter turbocharged engine that produced 260 horsepower. The first mass-produced turbocharged car was the 1976 Chevrolet Corvette Stingray, which had a 5.7-liter V8 engine that could be optioned with a turbocharger.
Today, turbocharging is one of the most popular types of forced induction, and is used on everything from passenger cars to trucks and SUVs. Turbocharging works by compressing air that is then sent to the engine’s cylinders. This process increases the amount of oxygen available for combustion, which allows for more power to be generated.
While turbocharging is the most popular type of forced induction today, it is not the only option. Supercharging is another type of forced induction that uses a belt or chain connected to the engine’s crankshaft to spin a compressor that forces air into the cylinders. Supercharging can provide an increase in power without adding extra weight like a turbocharger does. And while turbos are more efficient at higher altitudes where there is less oxygen available for combustion, superchargers work better at lower altitudes where there is more oxygen available.
How does forced induction work?
All forced induction systems work by compressing air that is then sent to the engine. The air is compressed by either a turbocharger or a supercharger. Both of these technologies have their own advantages and disadvantages.
A turbocharger is powered by exhaust gases, while a supercharger is powered by the engine itself. Turbochargers are more efficient, but they can cause lag if not sized properly. Superchargers are less efficient, but they provide instant power and do not cause lag.
The Gr Supra uses a turbocharger.
The benefits of forced induction
The benefits of forced induction are numerous, and the technology has been continuously improving over the years. Many modern cars utilise some form of forced induction, whether it be turbocharging, supercharging, or both.
Turbocharging is a relatively simple way to force more air into the engine, which results in more power. A turbocharger is basically a small turbine that sits between the exhaust manifold and the intake manifold. The turbine is powered by the exhaust gases, and as it spins, it forces more air into the engine.
Supercharging is similar to turbocharging, in that it also forces more air into the engine. However, instead of using exhaust gases to power a turbine, a supercharger is powered by a belt that is connected to the crankshaft. This belt essentially spins the supercharger at high speeds, which in turn forces air into the engine.
Both turbocharging and supercharging have their pros and cons, but both technologies can significantly improve the performance of an engine.
The drawbacks of forced induction
The main drawback of forced induction is the increased cost and complexity. The investment in a quality turbocharger, supercharger, or other Forced Induction Technologies can add several thousand dollars to the cost of a car. In addition, these systems require more maintenance and are generally less reliable than naturally aspirated engines.
The future of forced induction
In the Gr Supra, we utilize a single twin-scroll turbocharger to force air into the engine. The result is an impressive 382 horsepower and 368 lb-ft of torque. This forced induction system is different from other systems on the market because it uses a single, smaller turbocharger instead of two larger ones. This design allows for better airflow and more power, while still providing excellent fuel economy.
Which forced induction technology is best?
The Gr Supra is a performance-oriented vehicle that utilizes one of three different forced induction technologies. These technologies are turbocharging, supercharging, and electric compression. Each has its own advantages and disadvantages.
Conclusion
The Gr Supra uses a twin-turbocharged 3.0-liter inline six-cylinder engine. This engine is known as the B58 and it is also used in the BMW M140i, M240i, 340i, and 440i. The B58 is a nice engine, but it isn’t the only forced induction technology available. There are also superchargers and centrifugal compressors. So, which of these technologies is used in the Gr Supra?
The answer is that the Gr Supra uses a twin-turbocharger setup. This means that there are two turboschargers, one for each cylinder bank. The advantage of this setup is that it provides good power output while still maintaining fairly good fuel economy. This is because the turbochargers only need to work when the engine is under load, such as when accelerating or climbing a hill. At other times, they can spin freely without doing any work.
So, there you have it. The Gr Supra uses a twin-turbocharged 3.0-liter inline six-cylinder engine known as the B58. This engine provides good power output and fuel economy thanks to its twin-turbocharger setup.
