  • Journal Bearings vs. Ball Bearings - What's the Difference?

    2012-6-13 · Garrett Ball Bearing turbochargers spool up 15% faster than traditional journal bearings. This produces an improved response that can be converted to quicker 0-60 mph speed. In fact, some professional drivers of Garrett ball-bearing turbocharged engines report that they feel like they are driving a big, normally aspirated engine.

    2011-9-21 · 11,273 Posts. #13 · Sep 20, 2011. The difference in initial spool up between a journal and DBB turbo (everything else being the same) is about 150 rpms, almost un-noticable. The real benefit to a DBB turbo is its response time for recovering on the shifts. All the new DBB Precision turbos are completely rebuildable.

In addition to the spool time, the bearings are designed to last longer, which with less friction is completely feasible.

If all you want is 700whp 6266 @ 28-30psi will get you there with better spool. If you really want 750-800whp then 6466 but it's a lot laggier. I would vote 6466 for more headroom.
