I am looking for some kind of resource to decode holset turbo part numbers. It must be top secret info? I am wanting a turbo for my Big Cam IV, and wanting to go with a ht60 and a charge air cooler. I am not looking for a huge gain in H.P. just looking for faster spool time and cooler egt.

 

welcome to db
you could call cummins and see if they can help you with the numbers.

 

My local dealers only know part numbers by application. The specs of the turbos are not given to them. I'm trying to come up with a turbo combo for a big camIV. I am looking for a HT60 with a 22-23 cm2 housing. I am looking for a faster spool and a little lower EGT.
