So changing the ign advance (advance it or retard????) with the throttle
closed and little/no airflow will help to keep the turbo spinning?
Hmmmm..... The Ur-Qs do not have a WG freq valve, they are totally 100%
mechanical-primitive. What is the theory behind the WG freq valve approach
on the appropriate cars? Don't open the WG all the way?

Gotchah. Would another way to state this be to "vent the compressor output
to the atmoshpere" Vs 'feeding back' into the compressor inlet? This would
be a lot easier for me to plumb.....no need to tap into the elbow at the
compressor inlet.....prolly get those big, impressive fharts too..... :) ?

Kin I really get away with this on the CIS Ur-Q? Would the kitty have to
take a long walk?
