I've been wanting to showcase this for awhile now, but haven't had the same two turbos in the shop to do so. I finally had the opportunity today!

The main goal here was to provide a bit more information regarding the new Precision Waterless Air-Cooled Dual Ball Bearing technology and to present the difference between it and the standard Journal Bearing version.

The DBB turbo has the silver coated turbine housing while the Journal bearing turbo has the satin black turbine housing.

All of their HP Technology line-up is waterless dual ball bearing. I'm working on a new list to showcase what Precision has to offer. It's a long list!

they are still oil cooled/lubed. Turbos get far too hot to be self cooled, since they are exhaust driven.
