Performance & Application
The GTW3884R is engineered for high-horsepower performance builds that require a turbine section capable of handling divided exhaust pulses through a T3 divided flange, paired with the flow efficiency of a 3″ V-band outlet. Its ball bearing core supports quicker spool and sharper transient response compared to traditional journal bearing designs, while the larger 64.3 mm compressor wheel inducer and T04S compressor housing frame are sized to support serious power potential. This turbo is suited for builders targeting big power numbers in the 900 HP range who also want the responsiveness Garrett’s GTW Series is engineered to deliver. The built-in and machined anti-surge feature in the compressor housing further supports stable, efficient operation across the turbo’s operating range.
