keeping EGT's down
I was talking to a buddy who's owned his powerstroke for a long time. He was telling me some things on how to keep the EGT's down because I pull a gooseneck car hauler.
When driving, keep RPM's between 2500 and 3000 to keep more exhaust going through the turbo resulting in lower EGT's and the prevention of ruining the turbo. I'm not sure how I feel about that. Any inputs?
He uses royal purple for his oil and royal purple coolant and he claims that that is the largest contributor to keeping temps down
He uses a certain fuel adititve found online ( i forget the name) that has a higher lube factor (~200 microns, which is a lot higher than the powerboost that I use which I think is closer to 30 microns) lowering the temps.
Last thing is the inter cooler.
What do you guys think? Anything to add? anything you disagree with?

You've got the right air filter, DP and a good exhaust. What about your cat? If it's clogged, which it probably is, it'll be a restriction in your exhaust. If it suddenly got gutted or lost it would help. Do you have an EGT gauge? That is a must if you pull heavy or have the mods you listed. I pull a car hauler with my Bronco on it a lot - total weight around 15,000 more or less depending on how I'm loaded. Even though you may have the power to pull uphill in top gear, you may need to downshift to get those rpms up to keep the EGTs down. Keeping rpms up helps a lot, but you need a gauge to monitor it. The problem is not the turbo, it's the aluminum pistons. Aluminum melts at 1221*F. You should only push it if you're running alongside a Cummins or Dungamax!

When you start pulling heavy loads, or adding more fuel, the most important thing to have and watch is a pyrometer.
Thermocouple installed in the exhaust manifold so you can see how hot the exhaust is right outside the cylinders.
Then you know how hot it is getting instead of guessing.
EGT's get to high, downshift and back out of it a little so the temps come down.

I'm not sure about the fluids being the main contributor to keeping the temps down. I do know that adding an intercooler would be a great option for you in keeping your EGT's down. But if you are towing frequently, you really should have an EGT gauge.

IMO the main thing is the IC especially if you do any towing. You have the same setup as me except for stage twos instead of ones. If you read my other post on here now my egts are good even with a 48 foot trailer when its running right. I thought I read that with twos your temps tend to get higher especially when pulling. I did hit 1200 or maybe a bit above in some hills but normal driving was under 1000. Granted its not real warm yet, but i did have a 40mph side wind. I didn't have a lot of money when i started collecting parts for my ic either. Just bought part here and there and before you knew it I had everything. Get a pyro first and put it on so you know where you are at then you can adjust your driving till you get an ic. I bet you go up a lot bigger hills out there in CO with your trailer than me so your temps are gonna shoot up quick for sure.

Between the very long grades and the high altitude, EGT's can go through the roof rather fast.
I lived in Denver 8 years and drove a truck hauling swinging meat, so just a little experience with the Rockies and about every other mountain range.
Pyrometer first so you don't damage the engine before you get the intercooler installed.
Yes, the intercooler will help with EGT temps, but they can still get way to high when you are sitting there pulling a constant 7 or 8 percent grade for over an hour going up to Loveland Pass.

I thought I would here that. My truck still runs great but every time I tow I worry. My intentions are to get the pyro when the money comes.
No ones heard anything about the royal purple?

holy crap dude, you have 2s and no guages!? i have 1s stock nozzels and its not even funny how fast i can hit 1300degrees on the guage
never mind 2s uhhgg. get guages!! an intercooler is in the 1 month plan right now, sick of this temp issue, i can never lay in it for more than 5 solid seconds in 1 gear

Yeah I'd say if you have II's and no gauges that you've been pretty lucky so far. It should be your #1 priority to get a pyro gauge. My probe is still in the DP just outside the turbo housing. I know I need to move it to the manifold though. I think it was Rubber Duck or Tim who did a comparison of exhaust temps between the DP and manifold a year or two ago. Relying on that info I've been able to get by with mine in the DP for now. The longest pull I've ever done was dragging the Bronco uphill from Barstow, CA towards Vegas this past Nov. That climb goes up several thousand feet and just kept going, and going, and going. I did most of it in 4th at around 70-72mph with the RPMs in the high 2K range. Temps were 750/800. On the few short straight sections in the middle of the climb I got her up to 80ish in 5th, but as soon as the ascent resumed and EGTs started climbing, dropping it down to 4th again kept the temps in check. Coolant temp barely went above normal.

sustain more heat for longer periods than dino oils without a break down in the additive packages....just saying.

I did a search for that old EGT comparison thread but can't find it. I think it would be helpful to have it for this discussion - to show jchosler what kinds of temps he could be looking at under various conditions. Can anybody find it?

I would get some gauges soon. I just order a set of glow shift for my play tow that in progress Triple Pillar Pod Custom Gauge Package
