Message I honestly do not feel that BBs are a very valuable option for a 500 series turbo. These spool up so fast that I do not see you getting 500 rpm quicker spool, and that is the only way that I can justify charging $500 more for a BB turbo.

These use a 270 degree thrust bearing, which is fine for 20-22 psi. You really should not push these any harder than that, they are still relatively small turbos. 360 degree TWs are a good idea if you are pushing over low 20s in boost. For reference JWT 500, 600, 650 use 270 degree TWs, and seem to hold up fine.

When we release our 600 and larger turbos, they will have BB centers to help with the trust loads as well as spool up.
