Mine is sitting at the machine shop, just waiting for the coated bearings to come in then I can go pick the pieces up to assemble.

I don't know of many people running this hybrid setup.

Hoping to pick it up this week. Had some issues where the bearing coater apparently ruined the bearings (mains/rod/cam/thrust) and I just found out a little over a week ago.

Machine shop ordered Mahle/Clevite performance bearings for everything and are just waiting on the mains to arrive to final polish the crank for 20W50.

They said it was the best balancing duramax rotating assembly they've done.

Hoping this helps my stock crank live.

CP-Carrillo recommended 0.008" piston-to-wall clearance. I had my machinist follow the CP-Carrillo specs on everything.

I got it running and I must say the responsiveness of this engine is insane.

Subd what material are the pistons? Standard Carrillo rods I presume?

The hybrid assembly uses a forged piston with a smaller wrist pin moved up on the piston to decrease overall piston height. This smaller wrist pin and new location also allow for a longer rod. A longer rod, in theory, should help the motor build torque by keeping the piston in the high-pressure zone of the cylinder longer as well as decreasing side load on the crank by generating a better rod to stroke ratio.

It really should shine at higher rpm.


Also, with this wrist pin and piston, they were able to shave 1/2# per cylinder off of the rotating assembly for a massive 4# weight savings overall (they save 12# on the Cummins!!) which is why I believe my motor is so responsive.

Below are the links to the CP-Carrillo announcement/catalog:
