boost gauge

[mongrel_83]

hey every one ive tied to hook up my boost gauge but havent had any success in finding a vaccum line except for the one coming from my alternator and that doesnt seem to work the gauge right does any one here know where i could tap this thing in its a 2.8 hilux any help would be great as i have only just got this car and wouldnt have a clue what boost it is running

You do have a turbo on your 2.8?

Vaccum line off the alternator tells you nothing at all. (unless you have a Variable Geometry Turbo)

Odds are its a waste gate turbo and therefore to measure the boost you need to put a "T" piece into the waste gate line.

You do not want a vacuum line thats negative pressure you need positive pressure.

Got some pictures of the engine at all?

Cheers

im thinking you mean the hose coming from the front of the turbo housing to that shiny lookin thing that i think is the waste gate if thats right i just have to cut the hose and put a t peice in is that right????

Yes mate.

The shiny thing is the waste gate actuator. Once a pre determined pressures occurs the pressure in the hose going on to the actuator opens the waste gate and limiting the pressure the turbo provides to the engine.

That hose should lead to the inlet manifold at some point.

Just "T" piece it where its convenient.
