What is the best extreme towing set-up as far as egt's?
Extreme as in sustained heavy high speed...

I have a 3" downpipe. How much cooler would a 4" run?

I have a diy intake with napa 6637 filter (equivalent). Is there anything significantly better?

I have a 6.0 intercooler. Is there anything significantly better? Is this significantly better than a S.D. 7.3 I.C.? What about aftermarket?

Would 3" plenums make much difference?

Would largerer injector nozzles affect temps (assuming the same quantity is injected).

I have a H2e turbo (not installed yet). Is this the best I can do (within reason)?

Anything I'm forgetting about?

Water injection is a subjuct unto itself and I hope to avoid the discussion until later (or seperately) assuming anyone takes an interest in this thread. PLEASE start your own thread if you can't wait.

 

You can't fit a 4" down pipe unless you want it to rub or you take the engine out and tunnel the firewall.

The intake will work fine, flows plenty of air.

There are better intercoolers but they all $1000+

3" plenums mean more air and more air is a good thing.

Injectors will make it run hotter. Depends on what you want to tow. A set of ACs would make a great tow injector.

The Turbo will all depend on your injectors. Weather it is to small or to big.

Straight water injection will help out with EGTs. CSIPSD can help you with that

 

I'm not saying I want to do any of these things, i'm interested in the affect on cooling.

What I'm trying to ask is (for example), will 160cc injectors w/stock nozzles run at a different egt than a 160 cc injector w/80% over nozzles when pulling exactly the same heavy load at the exact same constant speed on exactly the same course...

If someone used their truck for say pulling heavy loads on the freeway, where the exhaust temperature is the limiting factor, what would be of benefit and to what degree. No pun intended.

 

it all depends on the tuning, if you run the 160/0 on stock tuning its going to run like a stock truck but with 80% nozzles and stock tuning its going to spray 80% more fuel thus making your egts higher

 

You are missing the point...

According to what I stipulated, and according to you, If both trucks are towing the same heavy load, at the same constant high speed, side by side, One would require 80% more fuel to do the same job?... and run 80% hotter? I don't think so.

You can assume proper tuning and all other things to be equal.

 

With proper tuning and supporting mods you should be able to make them run the same. But if I was building a tow only rig I would not want to worry about my Pyro temps.

 

Wouldn't egt's be the limiting factor?

 

you could tow safely with hybrids if you wanted to and with your mods you will be fine towing with the right tuning with bigger injectors

 

Why build a tow rig that you have to keep watching the gauge? Why not build one that has plenty of power but doesn't get hot?

 

That is great advice. That is exactly what I want. How do we do that?

I am trying to make this a discussion about modifications to facilitate pushing the envelope,
Weather someone decides to do that is a personal choice and has no bearing on the discussion of HOW to do that.

What I am looking for is how to best be able to use all or most of that power without melting down. How to maximize the cooling and minimize the heat while doing the maximum amount of work in the shortest amount of time.

I know it won't fit.

In theory, would it help lower egt's and by how much?
I would never do this, but I still want to know.

---AutoMerged DoublePost---

I would never pay that much.

If one were given to me, how much cooler would it run than my 6.0 i.c.?

---AutoMerged DoublePost---

How much of a good thing? How many degrees would this scrub?

Maybe my title is confusing. I do not wan't to maximize my egt's while towing.

Let me re-title: MODIFICATIONS TO MINIMIZE EGT'S FOR EXTREME TOWING.
