The Dodge dealer and the meter mfg both say to put the probe after the turbo.
I e-mailed Cummins and here is what they told me.

"Thanks for your Email message.

We do not provide a maximum temperature limit.

If you install the pyrometer after the turbocharger it will be more durable and less likely to damage the turbo if it fails".

So I guess it is going after the turbo.

If Cummins won't give me any numbers then what good is a pyrometer anyway.

Pyro needs to be pre-turbo to get an accurate reading. Ram-On JRP

Yesterday I drove over 200 miles and talked to the local Cummins dealer.

The tech at the dealership said they always install the probe after the turbo and I should run it not more than 1100 to 1200 degrees.

I really don't know what to do, I value all the input I have gotten from the obviously experienced and knowledgeable people that have assisted me on this forum. When the dealer and the representatives of the engine manufacturer tell me to do it the opposite, then I am really at odds.

I got the new probe and wire kit yesterday and will install it today. I won't post here where I installed the probe so I don't upset anyone further.

Thanks again for all the advice.

Dan

Take your E/MAIL and stuff it , like i told ya call tech support like i did when i bought my Dodge Cummins and talk to a real live preson . I spent over and hour with this one Tech . and learned a bunch . Now i have only worked on diesels for just a mear 45 years and have done way more then my share of tweeken them to way beyoud what they came from the factory and i do know for a fact that when THEY GO THEY GO BUT WHEN THEY GLOW THEY BLOW. AND WHEN YA GET TO AROUND 1250-1350 it is melt down . Now if ya realy want to ask some of the Boys that are in the know on Hopped up Cummins then either talk to Gary of enven better yet Bruce at Pittsburg Power the Old Diesel Injection as they have been the best Cummins Hot Rod shop anywhere in the country . As bruce and i have had this convershion on place ment of the pyrometer probe over the years and with the new Isapro Pyrometers it is placed BEFORE THE CHARGER as this will give the best reading . Back in the day of the older Pyrometers the probes would melt off when they got to the 1250=1350 range and would go thru the charger and when ya went and spent 3000 bucks building a super hot turbo charger ya sure did not want to feed a pyrometer probe thru the turbine fins and that is why we would place them 6 inches behind the turbo so if it did melt off or break off it would just rattel around in the pipe . And with the probe placed inthe pipe the max temp you could run was 950 before ya melded a piston . But hay you do what ya want it"s your truck and you are the one that asked all of us for advice and we gave it to you at no charge.

Tractor Vet, What Charm school did you go to? Is it really that hard to answer his question with some suggestions , even if you may need to make them more than once? " Take your email and Stuff it" is what you told him . Remember you aint talking to one of your Hostages, hes here for assistance . If you cant help him without blowing a Gasket , then do us ( me) a favor and keep quiet.

I tell it like it is and if ya want correct info then get on the phone and talk to the tech"s at cummins as they are vary informative . The new way of service deptments and the new socalled service managers of today are dumber then a box of rocks . All they are are paper pushers .And they have know idea as to the correct way to fix anything or know the spec"s . So if ya don"t like my way all i can tell ya is OH WELL>

Tractor vet
Here is the problem with your "OH WELL" attitude.
When you start acting like a know it all jerk, people will stop reading what you have to say. Don't get your tail in a twist because someone doesn't take your advice, it's just advice and we can do what we want with it.

You guys (or probably there's only one of you) are the ones with the attitude, but I assume you're just trolling. Tractor Vet tells it the way he sees it. If you don't like the advice, you still got what you paid for.

You haven't contacted the right person at cummins. That was an unprofessional reply.
