Ecodiesel power derating as temps rise?

[Deleted member 22728]

since this engine is a fiat engine and is probably marketed to several overseas markets, I wonder if you were to take a gladiator to Mexico or South America if they would be able to retrofit the engine to local specs. Thus freeing up some of the restrictions and possibly helping the engine to run cooler.

It is a VM. In much the same fashion as Cummins is a Datsun (Nissan) powerplant

I expected you would be OK since ambient teps are do cool right now.

Ambient was 84f.

Ambient was 84f.

Try it at 100+

I realize what I’m about to ask makes me seem incredibly thick, but I cannot decipher if your response is a “yes” or “no.” So can you clarify your response to the question?

You would need to research and see where Gladiators are sold outside the US with diesel engines, and what emissions equipment they are equipped with. If you have it modified to match another country's lesser emissions standards, you then have to apply for an exemption to legally drive it here. You can modify it and remove the emissions equipment, but you would need to find an area to register it that doesn't require yearly smog checks or vehicle inspections. Once it's modified, you also lose the engine warranty.

cool, so I can be like 65% of Texan Diesel owners who straight-pipe their trucks and not worry about emissions because they won’t be inspected for?

I’m late to the party on this one, but has anyone mentioned that if your EGT’s rise above 1,400F for more than a minute that derate will begin to occur without indicator or warning messages illuminating? I pull a 20’ travel trailer with mine on 37’s and have seen all of the temps you all are seeing without issues. I watch EGT’s like a hawk while towing and if it hits 1,400F I take my foot out of the pedal some and never seen a derate since. I strongly believe that issues being discussed in this thread are generated from EGT’s. I live in MN and have a few bigger climbs here and there and the EGTs hit 1,400F quickly. Especially in 5th or 6th gear.

Airstream and Diesel G waiting for the next pull.

This pic was taken as I crested the climb north from Camp Verde, AZ, to the weight-station/rest area. The trailer being pulled is a 2014 28' Airstream International; the oil temp spiked to 240f when I had to increase speed to 70mph in order to overtake a slower RV. Once I resumed 62mph, oil temp returned to 235f, then back to 220f at the Sedona exit. Coolant held at 217f, and the venerable 8HP just barely fanned itself at 199f. With 4.56 gearing on 37 13.50's, it has little difficulty holding 7th on the grade while using cruise control. And finally, intake air temp dropped from the insane 199f pre-scoops to 88f, although ambient air was about 20f higher on the prior figure. I feel, that as far as my needs are concerned, this is a good balance.

Edit for pore grammer

So, reading your previous post...
Did you do the S&B Vents only (e.g. not the model with direct feed to S&B compatible CAI)? Hence, the 2/3 trim on the stock air intake boot. So left scoop you’ve got air going over EGR cooler, and right scoop feeds air near the intake filter.

Any worries about water coming in the vents, or does it look like rain will drain around the air intake ok? (I know you don’t get much rain/snow in AZ, but in Montana… suppose I could use their covers in winter, as I don’t think I’ll have a cooling issue in winter).

Other than the vents and the gearing, did you do any other mods?

The lower portion of the scoop, the part the underhood "sees", incorporates a dam and levee ridge system that retards, not prevents, most water intrusion. As a lark, when washing mine last week, I pointed the hose directly into the scoop, then raised the hood. Yes, water was around the ports.

Apart from the aforementioned, no other mods. I am a life-long production technician; I get to see the after-effects of "chips, pedal-commanders", and the like. The engineers that, are very MUCH Jeepers, do their best to leverage what papa margin and mama gobment require, and, in my estimation, have one well with the JL/JT diesel platforms.

Has anyone noticed a connection with the overheating issue and front bumper mods like winch,lights etc. that might be restricting airflow? I currently don't have any of the overheating issues but I would like to add a winch and lights and don't want to start seeing problems. I live in the midwest and don't plan on doing any towing.

 

[Deleted member 22728]

Of course. Fully 1/5 of the cooling package - 2.0 gas, 2.0 grass-fed, 3.5 gas, 3.5 vegan, or any other incarnation...are simply limited by "7-slot" real estate. The final fifth, or perhaps fourth, go to war over the limited air supply (awesome band) that begs for heat exchange. It gets worse whit the factory steel bumper, coupled with whatever du jour winch of the day.

It's been a while since I posted in this thread. I went and used insane diesel oil filter kit and tied in an oil cooler and place it in front of the radiator. It added 2 qt of oil for total capacity to the system. Since I'm on 40" tires and on 4.88 gears at 85 miles per hour on the highway It frequently climbs oil temperatures to 246ﾟ. However after Installing the oil cooler and filter, I have not seen oil temperatures go beyond 234ﾟ and that is under heavy load. Therefore I have seen a temperature decrease on EOT of at least 12ﾟ by using a bypass filter.

Got pictures of your install?
