A long time ago when I was running Jeeps that had vacuum operated  
windshield wipers, I had an accessory called Electrovac. It was a 12v  
motor integrated with a rotary vacuum pump. It put out quite a bit of  
flow to keep the wipers going when you were going up a long hill. A  
quick search of the web didn't turn up such an animal, but I know they  
exist. It might be a decent candidate for maintaining brake assist  
vacuum on a turbo car if you switch to the vacuum boost approach  
that's used on the non-turbo cars. It would work even better if you  
had a small vacuum reservoir tank that gave the system some compliance.
Good luck,
