> Also, alot of dsm guys have to run restrictors on journal bearing turbos, too much oil will blow your seals and even slug turbo. I have seen a 1k rpm difference in spool when I stepped it down with a restrictor on my PTE

why do they need to restrict them? what psi for oil they running? Us LS guys run as high as 80psi and none of us with correct drain size and journals need restrictors. Use -4 feed and minimal -10 drain and be set
