BTW Note the weird pressure gage. It goes from
30 inches Hg vac to 30 inches of pressure above
atmospheric. Good kind of gage to use in your
cooling system to be sure the system is functioning
properly.

Paul,

That gauge is not so wierd at all. Look at most turbo boost gauges and
you'll see that they show manifold vacuum on one side and boost pressure on
the other. They're as close as your neighborhood speed shop.

Looks weird to me :) I have never owned a turbo charged car
unfortunately.
