Anyone have their Probe post turbo?

Interesting thought. I had always planned on pre-turbo if I ever installed an EGT gauge, but the Jacobs exhaust brake I just installed is pre-drilled for a probe. Sure would make it easier to install. Why doesn't Dodge pre-drill the exhaust manafold and eliminate the risk of damage to the turbo?



For anyone with experience with both pre and post trubo probes, would having only a post-turbo EGT be of any value for towing heavy, or would the numbers be pretty meaningless? In other words, if I had a post-turbo EGT, could I add XXX degrees to the readings to approximate pre-turbo numbers for the sake of preventing engine damage?

KEN !!! That is where I had the first pyromiter on the 00, held it at 900 and cooked it within 5 mi of home on first tow.



Haven't cooked one since with probe pre turbo.



Just My Humble Experience.

I have one pre and post. On the post I installed under the elbow with it installed on the truck.

Like Dieselman, I plan to go pre and post. I already have post. I use an Isspro gauge that is color coded. I think the "red" zone begins a bit above 900. I've always been of the opinion that the position of your probe depends on what you're looking to protect. A post-turbo gauge will allow you to protect the turbo, a pre-turbo gauge will help you protect the engine (pistons, valves, and exhaust manifold). Post turbo gives you an idea how the engine exhaust effects the turbo. Pre turbo gives you an idea how your load conditions effect the engine.
