Boost Controller and Switches

I wanted to put in a some toggle switches for a 2 stage boost controller and manual fan switch, hmm.... Once again I wanted it to look stock, so I made a trip to the junkyard and picked up a radio trim panel from a van that had rear heat, grabbed the switches from next to the ashtray from a couple vans and here is the result.

I looked at a lot of differant ways to make a boost controller and ended up making a combination of a Gus design and a Dempsey one. I made it with some solenoids from a parts Lebaron I had and a Grainger valve. I also plumbed in a pressure switch to prevent it from boosting any higher than where I set the pressure activated switch. On low it is just the turbo out nipple to the wastegate (5-7psi) on high it is through the G-valve, and at that time I had it set to 11psi. With the quick spoolup of the G-valve it was a good improvement over stock.
