Post Turbo EGT install

[testraub]

Okay read the posts and have decided to install my Pyro POST Turbo (Yes I expect flak for that) I'm looking for info as to others who have installed there. Pictures, tools needed, etc.



Thanks!



And PRE TURBO guys... ... Please... . I decided. I ain't planning to go much over stock on the engine. It works fine just the way it is... .

Good choice, nothing wrong with post turbo, pictures in my reader rig where I installed mine, I used a right angle pneumatic drill, worked very well.

Your choice. WHY?

 

[rbattelle]

I removed the elbow, drilled/tapped, then reinstalled the elbow. It's not a very hard job, and it gave me a chance to coat all the clamps and everything with anti-seize compound.



I don't think I have any pics of my thermocouple installed...

Tom - why did you decide to go post turbo? Easier?

 

[testraub]

Not easier not by a long shot Just no turbo issues and i don't plan on any high grade uprades No 100HP etc

What issues??? Post turbo you will never have an accurate temp reading (must interpolate). You will have a more accurate turbo cool down temp, but that's about it. If you don't really care if it is accurate... why bother putting it in????

See? I KNEW the pre turbo guys couldn't resist

 

[RJOL]

You're right... Just to hard to resist when I read your thread. First... You don't have to goose your CTD up 100HP before you can see high temps while towing. There have been guys with stock trucks that have seen temps over 1200 degrees. Second... If you're going to put the gauge in, put it where it will do you some good. The best, and most accurate place for the probe is pre turbo, and probably in the #5 or #6 exhaust port. But... in the final analysis, it's your truck... put it where you want...

Took the words right outa my mouth. Heck just tap into the exhaust pipe somewhere heading to the muffler. Or just mount the gauge and make it light up. Placebo affect.

I knew there was no hope for this thread not turning into a pre vs. post war.



Testraub - mine is post-turbo. Don't get hassled by "the man"! Fight the power!

I agree with the post turbo, and that's where I will put mine if I ever do install an EGT. Waiting to see if BrakeSmart ever gets the EGT/Boost feature for their controller. The Jacobs exhaust brake is pre-drilled for the probe. I read some where on the TDR that Cummins recommends post turbo.

How do I install a post turbo pyro in a truck with no elbow? I have a Banks exhaust, and it mounts to the flange on the turbo. It seems the 4" tubing is too thin to hold a NPT fitting too well.

BTW... . My current pyro is mounted between 3 & 4. I'm putting the TST pyro by #5 when I get it

Drill a hole and weld a nut on the pipe.

Drill a hole and weld a nut on the pipe.

A 3/8-16 nut drills out very easily to 11/32", then taps with 1/8-27. Just did this the other day when mounting my post-turbo probe in my downpipe.



Oh, and I've also got another probe in the manifold reading cylinders #5/#6 - so hopefully I get accpetance from both pre/post camps

A well respected vendor told me that there was a danger with pre-turbo. Seems you could burn the probe off and wreck your turbo. I've never heard of that. Is this possible? Thanks, RC.

There have been guys with stock trucks that have seen temps over 1200 degrees.

Here in Colorado where the air is THIN, it's hard for me to keep EGTs in check. The temp can easily reach 1400 degrees unless I'm real careful. There was still plenty of power to be used but, I kept backing out of it to keep the EGTs down to around 1250-1300. That was going over Loveland Pass towing about 8,000 lbs. My pyro is pre-turbo BTW. My '01. 5 had the pyro post-turbo and I always added 300 degrees mentally and used 950 indicated as max for a rule of thumb.

If your truck is stock there is no reason to back off based on the readings on your EGT gauge no matter where it is placed. If you could burn one of these trucks up by holding to the floor there would be tons of people burning up motors all the time. There are a lot more people driving these trucks that use and work them without any knowledge or concern about EGTs than there are people who do. As long as you are stock and towing within the specified limits of the truck it is very doubtful you will be able to hurt it, even at high elevations, if you could there would be a warning in the owner's manual, and a EGT gauge stock. EGT gauges are interesting to watch but on a stock truck thier only role in preventing damage to the engine is to monitor shut down temps.

I had these same concerns, with my 2001. Heard the "post turbo" guys say that this was a possibility and they would never put the probe "pre turbo. "



I'll issue the same challenge I did almost 5 years ago. If there is anybody on the TDR that has first hand knowledge of a "pre turbo" probe coming apart and taking out the turbo... post it here. I don't want to hear from those who say "I know someone who "HEARD" of this happening.



This "pre turbo" danger is like an urban myth. The chance of this happening is so rare, if ever, in a stock setup (non racing, competition, etc. ) that it is not worth talking about...
