The concept of an e-turbocharger has been floated for some time, but it took the might and billion-dollar research and development of Formula 1 to engineer a production-worthy product. The supercharger is used to generate more immediate torque, while the turbocharger extends the amount of top-end horsepower.Īn example of this would be Volvo’s compound charged four-cylinder which is used in the T6-grade cars and SUVs.
Compound ChargedĪ compound charged system is when a turbocharger is paired with a supercharger.
According to the man who took it to 304 mph, it’s a rush. Bugatti mates two large turbos and two small turbos to an 8.0-liter W16 engine to produce a total of 1,500 horsepower. The Bugatti Chiron is the only production car that uses a quad-turbocharged setup. The setup remains generally the same as a single turbo system, unless you have a stepped twin-turbocharger system that pairs a small turbo with a large turbo to eliminate lag.Īn example of this would be a McLaren 570S. Twin-TurbochargedĪdding a second turbocharger increases the amount of air that can be forced into the engine to create more robust power and torque. In the aftermarket, it’s one of the most popular tuner upgrades.Īn example of this would be the Honda Civic. It features a single turbine, and in the mainstream consumer market, it is generally used in more pedestrian cars that don’t need a lot of horsepower or torque. Single TurbochargerĪ single turbocharger is the most common type of turbocharged setup. There’s a great variety of turbochargers and turbocharged applications. As such, if someone adds a turbocharger to an engine that was never meant for one, they’d have to reprogram the engine’s electronic control unit (ECU) in order for it to function properly. ECU TuneĪ turbocharged engine’s electronic brain needs different calibration for fuel-to-air mixtures and ignition timing, compared to a car with a naturally aspirated engine. WastegateĪ wastegate is a valve in between the exhaust intake and the turbocharger that bypasses the turbine to control the boost pressure. To reduce the temperature of the charged air forced out of the turbocharger, a secondary radiator, or intercooler, intercepts the air before it reaches the engine. The turbocharger itself resembles a snail and features an air intake, an exhaust intake, two different impellers (a turbine in the rear and compressor toward the front), and a charged air exhaust that goes to the intercooler. There are four parts that allow a turbocharger to work. Plumbed to both, as well as the car’s air intake, a turbocharger uses the exhaust gases to spin the turbine which then forces more air into your car’s engine and increases the car’s power. A turbocharger is a small turbine that sits between the engine and the exhaust.
