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"

The Air Research, is actually a re-badged Garrett, and the turbo from the Cat, will be a re-badge also. Without seeing it, our guess would be a Schwitzer (4LE303). Hope it helps you in info searching. Compounds.....??? This sizing for secondaries would require copious amounts of fuel.
 
Ha no compounds yet I just picked them up cheap and hope to resell. Yeah i knew it was a Garrett Im just having trouble finding another one like it online to find a value for it. The Garrett is non waste gated

The CAT turbo is internal waste gate and needs rebuilt, here are some pictures

will do, I know it was off of a 1977 mack inline with an inline 6

Ill post the other number on the turbo tag, this is the one i had posted first: serial No. SFR0405 R
If you mean the build plate on the engine thats about an hour away, should have written the specs down.

Click to expand...

so did you sell the cat turbo?
 
Just cleaned a little on the plate and I found the label P/N so the part number is 631GC5106X I was unable to find much from google with this number.
