Why Garrett?

It's Simple:

Why choose Garrett?

 

A turbo is a high technology product that requires superior design and intensive capital to produce. It must meet the severe requirement that only a world class manufacturer like Garrett can achieve.

Garrett is one of the few turbo-charging manufacturers that subjects our turbos to several OE qualification tests. These turbocharging "qual tests" ensure Garrett produces a safe and reliable turbo for OE applications. When you buy a Garrett turbo you can be sure it is a reliable one!

 

On-Engine Durability - A 1,000-hour general turbocharger durability test that is run on-engine in one of Garrett's engineering laboratories. Some engines die before our turbos do!

 

Gas Stand Cyclic Durability (aka The Non-Sissy Test) - A 500 hour general turbocharger durability test. This is basically a "beat the crap out of the turbo" test. Survive this one and you've got one tough turbo!

 

Compressor & Turbine Housing Containment - A compressor/turbine wheel is weakened to "hub" burst at a specific speed. No portion of the wheel is allowed to penetrate a "containment shroud" surrounding the turbocharger. A test to ensure safety.

 

Shaft Motion - The maximum tolerances of the bearing system are tested for rotordynamic stability beyond the maximum turbocharger operating speed. This means no bearing problems and a long turbo life.

 

Thrust Bearing Capacity - A test that stresses the thrust bearing at extreme conditions. This test makes sure your Garrett turbocharger can tolerate the load you put it through.

 

Compressor & Turbine Seal - Multiple turbochargers are run on-engine under conditions designed to cause seal leakage. No significant leakage is allowed during these tests.

 

Heat Soakback - A turbocharger instrumented with thermocouples is taken beyond maximum operating temperature and shut down hard! Repeat the test four more times and make sure maximum temperatures stay within our strict limits to avoid oil "coking" or build up inside the center housing. This is particularly critical for high temperature gasoline applications.

 

Compressor & Turbine Performance - The entire operating range of both the compressor and turbine are mapped on one of Garrett's "Performance Gas Stands." These test cells are calibrated to strict standards to assure accuracy and consistency.

 

Compressor & Turbine Blade Frequencies - Garrett has strict requirements for compressor and turbine blade natural frequency. This is critical on large trims where the blade must be stiff enough to withstand potentially damaging vibrations.

 

Thermal Cycle - A 200-hour endurance test that cycles the turbocharger from low temperature to "glowing red" every 10 minutes. To ensure a long turbo life, no cracking of the turbine housing or distortion of the heat shroud are allowed.

 

Rotor Inertia - A measurement made to document the rotational inertia of Garrett's compressor and turbine wheels. Garrett's products are known for their high flow / low inertia characteristics.

 

Shaft Critical Speed - An analytical "test" that ensures that destructive shaft "critical speeds" are well out of the turbocharger operating range. For example, large wheels may require a large shaft diameter to avoid the "shaft bending" critical speed.

 

Compressor Fatigue - Garrett will not sell compressor or turbine wheel castings that have not passed a strict "test to failure" cyclic fatigue test. Garrett runs tests on a regular basis to ensure quality and to constantly improve our products.

 

Turbo Vibration - The entire turbocharger is vibrated on Garrett's large shaker table. Vibration levels are monitored to ensure product durability.

A Garrett turbo offers you the best value in terms of quality and competitive price. A quality commitment goes way beyond the manufacture of product. At Garrett, it has to do with the very aspect of business life. Protect your investment today. You can relax, enjoy, and drive with confidence with the knowledge that your Garrett turbo is a reliable turbo.
