Hey guys just picked up two turbos, one off of a CAT 3116 and another off a mack truck. The CAT turbo looks like it was built by CAT and has a split t3 or t4 flange, anyhow the one Im having trouble finding info on is the Airesearch turbo off of the mack. It has a split flange which i think is a T6. The Airesearch Inducer:65mm Exducer: 93.8mm serial No. SFR0405 R It also has M11 on the intake housing and "11" on the body The intake is 3.5" exhaust is 4"
