Typical deltas on spool achievable on b1 series with the QSV device is around 600rpm and about 500 for the MFT 63mm(not surprising, as its efficiency is not shining on low rpm). On larger b2 series stuff, most of them see 800-1000 rpm gains in spool. A HTA3582r on a valve with a 1.06 housing is about 400 rpm gain for reference. The b2 stuff with a functional valve is insane. We can outspool a non valved 8374 on a .92 housing with 9180 .92 housing with a valve pretty easily. Cake and eating right there.
