Not quite correct - there's full engine vacuum at downstream of the 
throttles but this drops as the throttles are opened. Full throttle sees 
little or no vacuum advance.

Basically what the DeLorean setup does is to run more advance under 
light throttle - which is done on a lot of modern engines to clean up 
emissions (making sure the burn is complete). Euro PRV's circa 81 didn't 
worry too much about this.

There are numerous different vacuum setups in my Renault manual - some 
even using the delay valve on ignition advance for engines used at high 
altitude
