Additional Notes

GT 72 straight vane rotors are cast from premium grade, proprietary Spec-37 iron alloy. This material exhibits long wear, high thermal stability, and excellent resistance to distortion in high heat. Modern foundry and machining techniques hold close tolerances on face and vane thickness. Combining the correct face thickness with a 72 vane casting provides superior heat management and long service life with low rotating and unsprung weight. Asymmetrical GT grove pattern and the straight vane design also makes it possible to use the same rotor on left or right hand mounting locations.
