I have an 05 Dodge 2500 with the obvious 24V engine and I am trying to locate a place to put the probe. Is the manifold above the turbo thick enough for pipe thread or the elbow behind the turbo thick enough. should I drop the exhaust and weld a bung on the pipe behind the elbow. where have you guys mounted the probe, If nobody can answer then can somebody show me where to search. thanks for your input.

 

I drilled mine right where #3 dumps into the manifold. pre-turbo will give you more accurate numbers.

oh, BTW, the manifold is thicker than you think, I would guess about 1/4 inch thick

 

Hey thanks for your inpupt I'm going to pull the turbo tonight and start drilling and tapping.

 

just to let you know there is no need to pull the turbo, I used a heavy gease that held onto the metal shavings and did the same thing when I tapped the threads. I did head a little metal hit the turbine fins, however they are not moving fast enoguh to cause any damage
