Pressurize Carburetor 

Pressurize Carburetor R1 To get your vacuum carburetors to work with Turbo you need to pressurize them You need to pressurize above and below the diaphragms You also need to pressurize the flout bowls This instruction is for the R1, but the principle is the same on all vacuum carburetors  My carburetor setup is stock except Needle down one clip (leaner) Pressurize diaphragms Above  the diaphragms On the R1 you have two holes in the slide that will pressurize the top of the diaphragms.

Pressurize diaphragms Below the diaphragms Static pressure To get pressure below the diaphragms you need to connect a tube to the vacuum air vent for the diaphragms You need two tubes, one for carburetor 1 and 2, and the second for carburetor 3 and 4 Connect this tubes to the plenum camber

Pressurize Flout Bowls Dynamic pressure The tubes should be mounted to the air ventilation for the flout bowls (The thin tube in the picture) You need two tubes here also one between carburetor 1 and 2 and the second between carburetor 3 and 4 Connect this tubes to the pitot pipe on the plenum camber The pitot pipe creates the Dynamic pressure

Connect to Plenum camber To pressurize your carburetors connect them to the plenum camber   Pipe size on plenum The small hole in the pitot pipe that's goes through the big pipe is 4,5 mm The small pipe is 8.mm inside 10 mm out side The big pipe is 45 mm inside The small hole in the pitot pipe has to be in the middle of the big hole
