ok i finally got another housing milled out for the thicker bb heat shield piece, and spool problem is fixed. 10 psi by 3000 15psi by 3500. i think it was spacing the turbine wheel too far away from the turbine housing. spool seems to be about the same as the journal bearing, although i still hear the exhaust leak rattle sound. but im happy with it. i will try to get it on the dyno soon and see where shes at
