How to Know If Your Turbos Are Going Bad

A turbocharger is a compressor that is mounted on the exhaust side of a vehicle and is intended to dramatically increase the horsepower of the engine. As the engine's rpm increases, the turbocharger forces air into the engine in order to increase the power. This is known as forced induction. If a turbocharged engine is not maintained properly, the turbo may fail, leading to a costly repair bill. There are several symptoms of a bad turbo, though not all of them are caused by a just a bad turbo.

 Test drive the vehicle and see how the power delivery is responding. A car that has a bad turbo or turbos will still run, but it will not produce the same amount of power that it does when the turbos are working the way they should. If the car's engine is producing much less power than it did before and accelerating slower, but still running, the turbos may be failing.

 Look for a "Check Engine Light" on the dash. In a modern turbocharged car with sophisticated onboard diagnostics, a bad turbo will usually cause a check light to turn on. Keep in mind though that a bad turbo on a turbocharged car is not the only issue that will cause a check light to come on. If there is a warning light, a shop with the proper diagnostic equipment will be able to use a computer to determine the problem.

 Find out if the engine is smoking excessively from the tailpipe. A turbo that has bad internals or blown seals will usually leak oil into the exhaust system, which then burns off, which produces smoke from the tailpipes. The smoke will often become worse as the rpm on the engine rises.

 Check the boost gauge if your vehicle is equipped with one. A boost gauge is mounted in the interior and reads the amount of boost that the turbo is producing. Not all cars have a boost gauge, but if your vehicle has one and it is not reading very much boost -- which can be anywhere from 9 psi to 14 psi for most normal turbo cars -- when the car is being driven, the turbos are likely going bad.

Transverse Vs Longitudinal Engines: The Pros And Cons

The way in which an engine is orientated can have a huge influence on the rest of a car’s design. Should the car be rear-wheel drive? What size of engine is expected? Are there space issues that could influence which way the engine lies? All these questions have to be answered by the engineers responsible for the car, as the powertrain setup can have a large impact on how the car goes, handles and stops. Looking at front-engined cars, the two possible orientations are longitudinal and transverse, with each having its own benefits and drawbacks that can govern which is chosen for the car at hand. In-light of this engineering decision, here’s a basic guide to the features of each engine layout and which is best for different applications. Transverse engines Transverse engines are mounted perpendicularly to the direction of travel, lying horizontally within the engine bay. This is predominantly used in front-engined, front-wheel drive setups but has also been implemented i...

Top 7 Cars with 200 Stock Horsepower

A decade or two ago you would have had to buy a sports car (and opt for the most powerful engine) if you wanted a vehicle with more than 200 horsepower, but today, that amount of power comes standard in a wide range of cars, from compact luxury cars to open-top sports cars. I have narrowed the list down to the top 7 of my favorites, and all have more than 200 horsepower (and less than 250) from the standard engine that comes in the base trim level. Read on to see our list of top 7 cars with 200 horsepower stock, sorted by power. Audi TT The Audi TT is a 2-door sports car powered by a 2.0-liter turbocharged inline 4-cylinder engine that makes 220 horsepower and 258 lb-ft of torque. All models use a 6-speed dual-clutch transmission that sends power to all four wheels using the quattro all-wheel drive system, making the TT a surprisingly good (and fun) all-weather car. Fuel economy is rated at 26 miles per gallon combined (using premium fuel) and the run to 60 miles per hour takes 5.3...

What is "anti lag" and how does it work

HOW THE TURBO ANTI-LAG SYSTEM WORKS Bang-bang (also known as ALS which stands for Anti-Lag System) is an engine management technique that allows to minimize the turbo lag time. As you may be aware of, turbochargers display what is known as lag time, which is the time needed for the turbine to reach its full throttle from the intermediate rotational speed state. The duration of a turbocharger's lag depends on many factors, including its inertia, airflow efficiency, back pressure, etc. The issue is partly dealt with by fitting a turbo dump valve, which acts every time the driver lifts his foot from the throttle. The dump valve will evacuate the pressure air coming from the turbocharger while the inlet manifold is closed so that the turbine does not stall and avoid possible damage to its bearings. In racing cars it is very common to fit the oversized turbochargers in order to be able to produce enough boost pressure and ensure sufficient engine output. Big turbochargers exhibit sig...
