My car is a '78SC with a 930 engine. I am using the stock SC brake vacuum line to the 930 manifold. There is a check valve in the factory line. The system works perfectly - even on boost. Every now and then when I'm carving the mountain I will hit a corner that may drop me out of boost so I use the brakes to slow the car and the throttle to keep me in boost. Brakes work fine.

The picture of the throttle bodies tied together (thank you) shows what appears to be the brake vac hose between the rear and middle throttle body. That is perfect.

Tim, I don't suppose you'd let me borrow that engine and tranny for a weekend, say November 3-5? HA!
