A clear demonstration of the inherent superiority of Garrett's ball bearing design is in the launch of a turbocharged drag race car. The two-step rev limiters used to build boost on the line expose the turbo to the harshest imaginable conditions of pressure spikes and scorching temperatures. Where lesser turbos often fail catastrophically, Garrett ball bearing turbos regularly shrug off these brutal conditions time after time. In fact, many drag racers running Garrett ball bearing turbos have not needed to rebuild or replace their turbos for multiple seasons.
