Red's deuce/camper project

Not much if you ever plan to tow anything. You can always turn the fuel back down though if you get an itch for a trailer.

Boo. I will be loaded down from time to time.

If you install an exhaust cutout close to the engine end of the system you will have more room to turn up the fuel when you are towing if you open the cutout. It will be louder though of course. The larger, or shorter your exhaust system is the better it keeps the egt down. Just an option for you to consider.

Won't do a cut out, but a better turbo is likely

A higher pressure turbo will also cut your EGT's down.

If you put more air in, you have to let more air out. Otherwise you start building heat up just cruising easy.

Yes, that's where a better turbo helps. Couple years ago the 6.5L diesel guys were having the same issue, stock turbo was the limiting factor. Found a better flowing turbo that helped all the way around (torque, egt's, fuel economy). The multifuel has the same hurdle in my opinion.

I agree but it still is true that size and design of he exhaust system has a large impact on gross egt. Every bend in a diesel exhaust acts as a kind of restriction, slowing the flow of gasses and building heat. Did you ever notice how on the factory exhaust the paint would turn red or burn off down on the bottom portion of the J-pipe and at the very top where it makes a slight curve before terminating? I'm not saying that just a better turbo won't do the trick for you, just sharing some info and thoughts that I've had on the subject. And the fact that you ran the exhaust all the way to the rear just amplifies all this. What size pipe did you use again? 5"? You'd probably be ok with that.

Agreed, the more bends and restrictions the more heat is retained. The only bends in the exhaust I did are the 3 1/2" bend off the stock turbo (where I changed to a 4") and currently the 90 at the end, which I'm switching to a 45.

The stick turbo is a big restriction.

Took a break during the holidays, time to get back to it

Here is a link to some exhaust stuff Silverstate55 did, I especially like how he routed his exhaust to change the number of bends and reduce EGT. Someday I'd like to copy some of this myself.

I also really like what Silverstate55 did with the long "J" pipe. Eliminate it ! No more rusting out the bottom bend !

With the elimination of the J-Pipe, where does any water accumulation end up? IN THE TURBO?!?!?
Doesn't sound like a favorable diversion to me. IMHO.

Input????

On the m35a3 they eliminated the j pipe. Doesn't seem to be a problem.

Could someone link the thread showing how he eliminated it?

Get a cap for the exhaust pipe top. Works great.

Yes a cap would work, that's what we do with most of the engines at work (Detroit 60 series, 12v, and similar sized Cat).

Did some work with the mount for the bed winch last night. Tying it into the frame between the bed and the cab, over the cab mount. Will be a tight fit with a 4500 pound winch.

See post 91 for the link.

Partway done with the winch mount
