What to Look For in a Turbocharger

When you buy a turbocharged diesel vehicle, you are really buying a finely tuned, balanced system that’s been carefully engineered so that all of the components work together.

At IamDIESEL Diesel Service Centre, we get a lot of questions about diesel engine performance enhancement.  Invariably, people ask us if they should start by upgrading their turbochargers.

The answer is no – simply upgrading the turbo unit on your engine won’t necessarily improve your vehicle’s performance.  On the other hand, if you perform other upgrades in search of more performance, you should consider upgrading your turbocharger at the same time.  The carefully balanced air/fuel ratio that the manufacturer has designed the system to provide will be thrown out of whack if you change any of the variables, and you might need a different turbo unit to put them back in balance.  We always ask what the goal of the performance improvement is – quicker acceleration and better drivability, higher top speeds, or more power to pull big loads without compromising fuel economy and damaging the engine.  When we know what our customer is setting out to do, we can make a better recommendation.

Spool time

Installing a bigger turbo unit, one capable of forcing more total air into the combustion chamber, usually results in slower response when the driver depresses the throttle.  From an every day drivability perspective, we do our best to match the size of the turbines in the turbo to the application, and provide better performance without too much of an increase in spool time.

Exhaust Gas Temperature

One of the biggest reasons for upgrading a turbocharger is to reduce exhaust gas temperature.  If your EGT gets too high (for example, when pulling a heavy load up a steep grade) engine damage can result.  Higher capacity turbochargers can help combat this rise in temperature.

IamDIESEL Diesel Service Centre is the service branch of Western Turbo, Winnipeg’s premier diesel centre.  We service all makes of diesel vehicles, and really enjoy helping our customers reach their performance goals.  We recommend and install turbocharger units from Holset, Garrett, and BorgWarner.

Turbocharger Care and Maintenance

One of the most efficient ways to increase the power output of any engine, gasoline or diesel, without increasing the size and weight of the engine, is to add a turbocharger.

Turbochargers are used on all kinds of vehicles – racecars and big diesel truck engines both commonly employ them, because they’re often asked to provide maximum horsepower to get their jobs done.

Turbochargers improve engine performance by using the engine’s exhaust to power a compressor, which will force air into the cylinders of the engine, so that more fuel can be added while still maintaining the optimum ratio for efficient combustion.  Because more air and fuel are in the cylinder, the explosion produced on the power stroke provides more energy.  The performance improvement provided by a turbocharger far outweigh the increased load the system puts on the engine’s exhaust.

Turbochargers have been in use for a long time, and the systems are quite evolved.  You can generally expect your turbo system to last as long as your engine does.  There are, however, some considerations you need to make surrounding maintenance of a turbocharged engine.

The main problems that confront turbochargers are heat and lubrication related. Because of the extremely high speed that the turbo is required to spin at, conventional bearings would fail very quickly.  Turbochargers use a fluid bearing – a thin layer of oil that separates the mechanical parts to prevent wear and keep the moving parts in the compressor or the turbine cool.  Most turbocharger failures are caused by inadequate lubrication, or foreign particles in the oil.  This means that the key maintenance requirements for a turbocharged engine are oil changes at prescribed intervals, oil and air filter system maintenance, and oil pressure control.

Western Turbo is your Winnipeg area turbocharger expert.  In addition to maintenance and repair of turbo systems, we provide new equipment for the leading brands in the business – Holset, BorgWarner, and Garrett.
