6v92ta turbo boost

[sledhead]

hi guys     just installed a boost gage off turbo on exhaust about 16 " from turbo where a plug was in pipe. went for a drive and could not get more then 5lbs of boost at full power going up a hill, is this ok ? no smoke, runs up to 83 mph    thanks  dave

You're not meaning that you put the gage on the exhaust side of the turbo, are you?

[boogiethecat]

The boost gauge should be installed between the turbo and the intake manifold, not on the exhaust side.

That said, If you're looking at the exhaust side and see 5 PSI, I'd wonder (besides the gauge being in the wrong place) why there's that much pressure in your exhaust system.
Clogged muffler? exh pipe too small in diameter?

I was told by a diesel mechanic any point down stream of the turbo !!

You need another mechanic!!!!

he meant downstream on the fresh air side, not the exhaust side.

Mr. Sledhead sir:

Definitely NOT the right place to measure the turbo boost.

But one more question, supposing it WAS in the right place: What size wiring are you using between the engine compartment and the dash? If you are running 40-50 feet of wire, and using small-guage wire, you might get a tremendous voltage drop and not an accurate measurement.

Top mounted turbo on a 6v92t has a plug on each side of the air horn to hook a gauge up you are not talking about a electric gauge right,use 1/4 tubing to the dash instead of the 1/8 inch it will read 20 lbs under load +or -

good luck

One of those plugs on the exhaust side should take a pyrometer sending sensor, if I am not mistaken. (That is exhaust temperature.)

[Brassman]

The exhaust gas pyrometer goes before the turbo. Exhaust gas inlet temperature. Too high=new turbo.

[Aussiecoach]

Could anyone post a photo showing those plugs please

[Boomer]

Plug on hot side would be for pyrometer thermocouple.

[sledhead]

do not know where to look for a plug ,found 2 plugs below turbo on I think the blower ,1 left side,1 right side ?  1/4 " ,I have a 1/4 " air line from back to front and a boost gage   thanks dave

[luvrbus]

Those are the plugs either side will work

good luck

[sledhead]

to remove the plug it looks like a 1/4 "extenion will fit, will rust ,crap fall in ? and is it better on hot side or cold side   thanks dave
