Improved Turbo Life and Reliability
All Garrett GT-Series turbochargers have the provision for water cooling in the core. Water cooling helps control turbine core temperatures, and prevents oil coking on shut-down. Water cooling has been shown to improve turbo life and reliability.
Ball Bearing Core
Garrett’s patented dual ball-bearing core is the industry standard for ball bearing turbochargers. The Garrett system relies on dual angular-contact bearing races, which eliminate the need for a conventional thrust bearing. A Garrett dual ball-bearing turbocharger is over 4 times stronger in thrust than a journal bearing turbocharger, increasing reliability at high boost levels.
