Jeff Johnston started working at Aviaid long time ago and started his own biz a few years ago- He has a unique setup with a system that has steel balls in a venturi type tube that will close from acceration forces to contain the
oil near the pump in a wet sump system( sort of like the trap doors in other systems)
We have a drysump system that pulls over 20 inches vacume that uses a lobe type pump whereas the more common gear type pulled over 10 inches on the same configuration engine( 500 cid hemi 1380 hp 9500 rpm)
And I agree the fabrication is SUPER
