Should I Install a Pyrometer
Hey we'll be getting our new 05 F-350 XLT 4X4 Dually Diesel soon and I was pondering if it would be wise to install a pyrometer. If so were should you mount it before the turbo or after the turbo, how about having two gauges a post turbo and a pre turbo?
The truck will be used for towing and hauling a camper and 3 horse trailer. I know it already has a boost gauge I just hope it's not a switch.
Thanks John

I installed a pyro preturbo on my '03 to monitor temps while towing my 30' toyhauler. Truck and trailer together are usually in the 18,000 lb range give or take a few hundred.
Towing around SoCal, up and over the Grapevine, Cahon pass, and out East over the continental divide it never got up into the unsafe range - max was 1173 deg F as I recall.
I use the X-Monitor which has pyro, tranny, and boost all in one. It allows you to keep the driver's pillar handle too which is nice. It also has a flashing alarm if you exceed your preset threshold, and keeps track of the last max value since reset.
If your truck is going to remain stock and not have a tuner added, you probably don't really need a pyro gauge but it sure is nice to have. The tranny gauge is nice too because the stock gauge is just an analog idiot light.

I think it is good to have one. Especially when towing over mountains and having your foot on the pedal for an extended amount of time. You are probably safe without one if you are stock though IMO.

at what temp do you have to worry if you mount one in pre-turbo?
also how do you rectify it if you reach a high temp? just slow down?

I know guys that have had the same probe in 7.3's with 250k on them....

Just kidding, no one has ever posted in this forum or any other that one has broken off and caused turbo damage. It is possible to damage it if installation is done incorrectly but this is never been proven in my time owning a diesel and since I have been in this forum.
