Boost Gauges

[R338OY]

Where do boost gauges take their reading from? At the turbo, near the throttle body, or at the piping leading between everything? I'm trying to isolate where my boost leak is coming from. It's dropped about 3-4psi according to the gauge

Depends. *most* come from the back of the plenum. So assuming that, basically your leak is everything before that

Not helpful but thats kinda how it goes.

Just check around the clamps. It'll be around there somewhere provided you have not split a hose

Thanks R31Nismoid. Plenum eh? Guess my induction system's gettin ripped apart this weekend...

Probably a stupid clamp or something.

Cheers

Ye start with the clamps first mate.

Also give the cooler/piping a bit of a jiggle. If its moving around too much in one area, its likely near there is the leak.

You dont want to have too much free-play as it just leads to blown pipes/clamps

Never tried it myself, but heard pressurizing the inlet track with a compressor can get good results.

Crank the reg down so that the hissing from the hose isn't louder then the potential leak, and as Nismoid said, jiggle all the big hoses, pipes, listening carefully.

Good luck
