while rowing thou the gears the other day i was noticing and thinking

how does one make the vanes react or respond faster to commanded changes... ?

you auto guys probably don't realy have this to worry about as you don't see the rpm swings us hand shakers do.

so i was simply thinking the vanes are essentially controlled by oil pressure. correct? engine oil pressure very on RPM and temp.. correct? this in turn affects the speed witch the vanes can move (not including the restrictions in the actuator valve.)
what if turbo oil was re-plumbed to run off a separate , external gear pump (with its own suction from the oil pan) set to keep a constant pressure lets say 60# or so
some fancy plumbing with check valves can keep the factory oil feed as back up if gear pump dies......


maybe even modding the actuator valve for little more flow.. dont know on this... haven't puled one off the turbot to know what it looks like.


any one else feeling what thinking .......... thoughts and ideas....

Are you just trying to not loose as much boost on shifts? You can adjust the vanes to be closed more then you let off the go peddle to shift. Should help it hold some and at the very least come back up faster.

basically yes trying to keep boots up
with closing vain it seems to cork up the top end ( is best i can describe) and starts bouncing the boost levels about 5 psi for limiting. ( from 25 to 30 psi)
and feels like it pulls fuel away as well , ( i haven't loggd this to be sure)

maybe this can be solved with injection timing havent yet dabbled much in that aria of tuning but over all think motor would also respond better to parts that react right when ECM tells them to do so.
