'GT' vs. 'T' Series
Why is Garrett GT better than T product?
- Product Simplification - T product typically contained 54 components, compare this with GT technology, which has drastically reduced the number of components by more than 45% to average of 29! Reducing the number of individual parts drastically diminishes the opportunity for failure, thus resulting in smoother motoring.
- Journal Bearing - The bearing system in the GT turbocharger allows for improved shaft stability and less drag throughout the speed range. In fact, the GT shaft motion has decreased by 20%, which greatly improves the durability of the bearing system.
- Thrust Bearings - The new GT turbochargers have an increased load bearing capacity of up to 35%. This provides greater resistance to thrust bearing failure, especially when the combination of an oversized compressor wheel to turbine wheel is used.
- Improved Aerodynamics - The wheels used on the GT turbochargers increase the efficiency of the turbocharger system. Increased efficiency allows improved engine performance in each application.
- Wheel Trims - The GT range has several more wheel trims than the T range, enabling a more accurate match of turbocharger to engine that will in turn result in optimum performance.
- Piston Rings - The piston rings on the GT range are made from M2 tool steel. This material can withstand higher temperatures than traditional T range piston rings, making the GT product more appropriate for today's modern engines.
