The Garrett® G Series Turbine Wheel
The G Series turbine wheel includes cutting-edge ultra-high flow aerodynamics to boost response and improve flow. The technological improvements provide once unimaginable power levels by enhancing the spool and growing the frame size.
Garrett created the G Series turbine wheels with Mar-M super alloys so they can withstand up to 1050 celsius. In addition, the new turbine wheel has a peak efficacy of 74% and flows 15 to 20% more than GTX.
The Garrett® G Series Compressor Wheel
If you want to boost your maximum horsepower output, the new aerodynamic design of the G Series compressor wheel is your best friend. Its new sleek design increases the maximum horsepower output by up to 30%.
The aerodynamic design doesn’t just boost peak flow, but it also increases the power through its extensive operating RPM range. The compressor wheel increases airflow by up to 15% for 60mm and 30% for 67mm with impressive 79-80% efficacy. You can purchase the wheel in standard rotation or reverse rotation options.
The Garrett® G Series Turbine Housings
Garrett® G Series Turbine Housings come in stainless steel to ensure maximum durability; they can also withstand temperatures of up to 1050 celsius. In addition, they also include V-band CHRA to Turbine Housing interface to provide complete 360-degree rotation.
Garrett has designed the housings to be more compact, more efficient, and have maximum bypass port size to offer better boost control and minimize boost creep. Garret has made the turbine housings available in various configurations—including T25, open volute, and Vband—to ensure maximum choice.
Why The Garrett® G Series Is Perfect For You
