A turbocharger, or simply turbo (the slug), is a device that increases the power output of an internal combustion engine by forcing more air into the combustion chamber. This results in more fuel being burned and more power being produced.
A turbo works by using the engine's exhaust gases to turn a turbine, which in turn drives a compressor. The compressor then draws in more air, compresses it and sends it to the engine. This compressed air allows the engine to burn more fuel and produce more power.
What does a turbo-hole mean?
One of the drawbacks of a turbocharger is something called "turbo lag". Turbo lag refers to the delay between when you press the throttle and when the turbocharger starts producing boost.
This delay can be frustrating for drivers, especially in situations where fast acceleration is needed, such as joining a motorway or overtaking another vehicle.
Turbo lag is caused by the time it takes for the exhaust gases to spin the turbine and the compressor to start producing boost. This delay can be reduced by using a smaller turbocharger or by using multiple turbochargers (Think of the BMW 335i e90 models), but it cannot be completely eliminated.
Some manufacturers have developed technologies to reduce turbo lag, such as variable geometry turbochargers and electric turbochargers. These technologies help improve throttle response and reduce lag, but they can also add complexity and cost to the engine.
In short, a turbo lag refers to the delay between depressing the throttle and when the turbocharger starts producing boost. This delay can be frustrating for drivers, but it is a compromise for the increased power and performance that a turbocharger offers. Manufacturers have developed technologies to reduce turbo lag, but it cannot be completely eliminated.
Which Cars Have a Turbo?
Turbochargers are often found in high-performance vehicles, but they are also becoming increasingly common in everyday cars. Many manufacturers now offer turbocharged versions of their popular models. Some examples include the Ford Mustang EcoBoost, the Subaru WRX and the Volkswagen Golf GTI, but also in a Fiat 500, for example.
What Are the Symptoms of a Defective Turbo?
Like any mechanical device, turbochargers can fail over time. Some common symptoms of a faulty turbocharger include a loss of power, excessive smoke from the exhaust and a squeaking or grinding noise from the engine. If you suspect turbocharger failure, it is important to have it inspected by a qualified mechanic as soon as possible to prevent further damage.
What Are the Costs of a Turbo Overhaul?
The cost of a turbo rebuild can vary depending on the make and model of your car, as well as the extent of damage to the turbo. In some cases, a simple repair or cleaning may be all that is needed to get the turbo back up and running. In severe cases, however, a complete replacement may be necessary.
On average, the cost of a turbo overhaul can range from several hundred euros to several thousand euros. It is important to work with a reliable mechanic or turbo specialist to ensure you pay a fair price for the work to be done. Also, always request a quote before getting started. This will prevent unexpected costs.
