Ecodiesel power derating as temps rise?

[ZoneArc]

Well finally got to tow in the heat yesterday. I went from Vegas to Lake Mojave, roughly 75 miles each way. The temp gauage in the truck varied from 93-97 degrees.

Were your results after doing Insane Diesel bypass + Active cooler, or did you do an Active cooler direct to the block (not filter)? Just curious. I'm running ID's filter bypass with their filter and cooler as well. I have had good results but its not 100%. Still occasionally hitting 265+ and derates. But, it has to be some serious and long grades and I have to be moving above 60mph. .

Anyone have any experience with it? At $554, not cheap.

I looked at the Dyno ratings and the torque increase is a meager 4 lb ft. Not sure if its worth it for about $160 each for extra lb ft of torque. HP gains do nothing for the JTD as torque is what moves the beast. In any case, the HP gains were not that impressive either.

For about the same amount of money Banks will get you more than 10 x's the torque that this will.

Yep, lot of money for almost no gain and probably void your warranty!

Nope, 100% stock. What parts are you referring to? I haven’t been able to read this entire thread. Lol

Yeah not really interested in the gains, I’m happy with the power I get from the stock motor. Mostly talking in regards to oil temps and not being derrated.

I don't know if this has enough change to negatively affect the warranty. Its only a smoother tube that helps tame airflow.

Now do the Green Diesel mods to your JTD and your warranty will be voided to keep that in mind because a lot of people are recommending it.

Also the cheap Chinese oil filters for the JTD sold on Amazon and Ebay will also void your warranty if something happens to your engine and they catch you with one. Even if you switch out the China filter with a genuine one, they can still tell..........................

I'm also totally OK with the power output so long as it stays cool enough to run normal. O just want reliability and consistency especially while towing. I knew this thing wasn't going to outrun my Peterbilt or Ram 3500, but it should run as advertized?

The only thing that can help the high oil temps are a bigger oil filter. I had two diesel shops look at mine and said the factory oil filter is woefully small. The issue is where to mount a bigger one where it is protected. Then there is Jeep, dealer told me changing out the factory oil filter for a bigger one would probably void the engine warranty.

Too many comments here refer to the engine temps and it is the oil temps, not the coolant temps that are causing the de-rating and performance issues.

You just can't win.

I've been running OEM fuel and oil filters even though they too are made in China at $70 and $85 Retail?

I went down the "Add more power" in the past.........I'm more interested in power gained by efficiency. I used to laugh at Banks calculating the cost per HP/MPG gained, but I'm older and more experianced now. I only want ALL positive changes and willing to pay a few $$$ more for it.

No GD for us in CA. Cant even look at thier products with a local IP! Can't blame them with all the CARB and EPA stuff in the past.

Oil cooler is too small and if it were properly sized, then coolant temp would just cause a derate that much quicker from the undersized cooling system. I've had mine derate and coolant tremps were not happy at near freezing before so that kind of confirms it. It needs an external oil cooler to spread the heat transfer.

It does have an external oil cooler, it is mounted on the frame rails near the front. The problem is that it is too small for the motor. It seems to be like a smaller than you should have transmission cooler.

The shops that looked at it told me the same, it is too small but the issue was where to mount a bigger one and keep it protected.

Hmmmm.....I thought that external cooler was for the trans? I thought I remember tracing the lines to the trans and realizing the trans oil did not pass through the radiator like most vehicles and likely why the trans runs so cool.

Am I mistaken?

If that were an engine oil cooler, it would be easy to plus size it without plumbing issues.

There is an external transmission cooler but the oil cooler is a small heat exchanger built into the filter housing that cycles engine coolant through it.

There is no external oil cooler on the ecodiesel?

I could agree with you on that and that why the engine coolant temp climbs so high, but @steelponycowboy was saying its between the frame rails. That should be the trans cooler.

The charge pipes will have absolutely nothing to do with Inter cooler efficiency. What they CAN do is help with airflow(depending on stock design) and help with throttle response(rubber Inter cooler hoses will flex slightly with boost which hurts response).

I'm curious if the rumored new grill will make a difference. I'm guessing yes or since I doubt FCA would make that large of a change for nothing.

When it comes down to it, I think injection is going to be the route to go unfortunately. Just not enough room in the bay unless you want to go wild with your engineering. Turn on the injection when you know you are going to hit your temps such as inclines and keep it off when you don't need it.
