			Less friction = more efficient engine More efficient engine = more power using less fuel Or course, the downside is that needle bearings are less reliable versus journal bearings. I'd imagine service interval is a lot shorter for these needle bearings versus journal bearings. If you're building a "race engine", this is not going to matter. -Ted Last edited by RETed; 01-11-2011 at 11:02 AM. |
