Boost sensor location?

Hey Guys,

 

Finally getting around to setting up my boost / egt  and fuel pres / trans temp gauges.

 

Whaddya think guys? what is the best recommended location for the boost sensor? I'll be drilling / tapping 1/8 npt so I'm hoping / wondering if the aluminum intake just before the manifold would suit. Easy to take off without worrying about drill / tap chips getting into the intake.

 

I got all of the other sensor locals down. And yea, I know about drilling/taping the egt probe hole while the engine is running. Done that a few times on previous vehicles. 

 

Thanks!

They make aluminum and steel bolts. Use steel and you shouldn't have a problem with it snapping off unless you really over torque it.

The torque spec for the Glow Shift boost bolt thread adapter is 120 IN-LB (10 FT-LB).

Yes, 18 FT-LB is the torque for stock bolts but for this Glow Shift bolt the tightening specification is lower due to the bolt being hollow.

Wouldn't that make the gasket weak in that spot, I don't think I'd use that set up just for this reason. Not arguing jmo.

When I did my boost leak check I didn't get any bubbles from my intake gasket.  Of course I am only producing about 35psi max boost.  I might be a little more worried if I was running a big turbo or twins. :shrug:

This is the installation sheet for the boost gauge fitting and location in 2005 when I installed the Isspro gauge.  The boost bolt threaded adapter was introduced after this installation with all the venders now offering it for sale.  It's another part  they can make money off of and the customer doesn't have to hunt for it.

I used the boost bolt and torqued it as recommended in instructions(it came with my gauges) and when it broke I drilled and tapped elbow. Had it off to replace injectors.  Boost bolt broke when I was removing it. 

Yup has myself working on other truck.

Yeah for some of us running much higher boost like myself 47 to 49 PSI. Then consider the bigger guys with twins.
