one goes no where, is just the vent for the other side of the diaphram,

the other from memory is to boost pessure so somwhere on the inlet manifold.

that pic of the stock system is incorrect.

The blue VSV is the vent's for the s/c bearings, and is on when the S/C is on.

Picture looks fine to me.

The VSV for the s/c bearings vent is brown in colour, and the plug for it is grey, not blue. and lives just on top of the supercharger.

The ABV VSV is blue with a blue plug

The fuel pressure reg VSV is brown with a brown plug

been a while since i played with a s/c setup,
but i think u may be right.

anyone know what side abv is the vent?
what is the control?

[Rick]

The small pipe sticking 90 deg out from the body is where the vacume line is connected to, not the tiny angled down pipe thats just a vent.

If you suck on the small pipe it will move the spring loaded plunger.
