zero maintenance supercharger?

[DAVECS1]

Too many short trips. If I bought a diesel, it would carbon up and break. Know your vehicles needs before you buy it.

When I first retired from the AF, I was a shop maintenance manager for Caterpillar and then Detroit Diesel. Long haul trucks do great, but I saw a lot of pickup trucks with carbon problems. Don't even get me started on Generators. We would need to take a load trailer out yearly to get them warm enough to burn out the carbon. The places that went cheap and didn't the units would always fail when they were needed.

You were a CAT guy, I knew there was something I liked about you?

I am going with a Magnuson on my JT, currently waiting on all of it to come in.
Was trying to hold off to see if Jeep was going to launch a 392 JT, but that's looking bleak, and not to mention the state of new vehicle costs and wait time.
Bought my JTR used with 8k miles on it, if I were buying a new one, I would get a diesel.

Diesel was my original plan...

Then all the overheat issues for guys living at altitude in hot areas towing. IE out west which exactly where and what I'm going to do with my rig.

The SC is 10k basically said and done. A v8 swap as 30k+ when I priced it out.

Diesel was 4k upgrade but with the heat issues wasn't something I felt I could trust.

guys another potential solution is to get the diesel with 442 ft lbs of torque at like 1800 rpm. Diesel option is 6K more, factory, 100K miles warranty, no tuning...

Well those issues are not exactly widespread and there hasn't been any overheating exactly. It was getting hot enough to reduce power but no overheating.
Perhaps it is user error where they're forcing high load and high gear. Few guys on here use lower gears and do not get reduced power condition

agree saw the same complaints on the diesels ... never know if there is real substance behind some of the gripes u see on the forums and facebook groups tho

If the eng is shutting power down due to water and oil temps then umm it's overheat"ing" (I didn't say overheat"ed"). The reports are wide spread, just go read the thread after thread on it, and all have the same general characteristics.

In any rate, I don't own one ?

Well we can play with the terminology but in my mind overheating when you have to shut down the engine for it to cool off, to not get overheated.
In the reported cases, the engine did not need to be shut down. It just reduced power to lower temperatures.

I've had numerous instances of my old supercharged mercedes shutting the supercharger down due to oil temperatures in Florida summers. Any forced induction vehicle will run hotter than naturally aspirated.
I would be careful being confident in a non warranty backed aftermarket supercharger install, which uses pretty much the same cooling system but is pushing boost in an engine that is not designed to be supercharged. Plus you will be towing with it.
If the diesel engine dies, you have a 5 year 100K powertrain warranty. If the supercharged 3.6 dies, you are liable to fix it.
I'm sure there are lots of people out there who are towing without even looking at gages.
And also there are people here on the forum with no heat soak issues.

The Maggi system is fully warrantied full 3yr 36k miles. It does have a secondary cooling system for the supercharger.

The 3.6 plat form was actual designed for a turbo, that was never implemented.

So I'm not sure when you came up with all that.

Great you like the diesel, ok, I do to, however it does have issues. Your welcome to defend it, that's ok. But I didn't buy one because it doesn't work well in the JT due to cooling issues that are well documented (vs a 1500 where it works great).

I'm sure there are guys with a JT D and no heat issues. However every report of heat issues was hot high towing. Where I live town and travel; out west. Hence my decision not to go that direction.

Well if its getting hot enough to reduce power, its useless.

Its UNSAT that you can tow its rated amount, drive at X altitude or wheel it w/o reduced power mode.

If you look at it in a non-bias manner, there is not sufficient cooling surface or space to cool them correctly. Needs a better radiator, possible revised cooling fan(s), larger trans cooler and larger oil cooler.

So the magnusson has a warranty? But to get it to run “right” you need Dave’s tune.

I think using Dave’s tune would void the Mag’s warranty.

Jeep sure as heck would void all factory warranty for power train and electronics associated with the ecu. Axles, gears, brakes, transfer case, you name it.

Not to pile on, but I will ?. I tow quite a bit with my rig. It started life as a max tow. I went through the excercise of towing my mustang around and insuring timing, heat, and transmission temps stayed in check, even with 87 octane gas. I climbed the biggest longest grade I had available during the heat of a midwest summer, and did it a number of times. I have gone through enough fuel to make my wife a little fussy. Last but not least I left enuff power in it, in the worst situations it still felt viable, pulling a load

If something does go wrong, 3.6 liters with about 1400 miles on them usually go for around 2500 dollars sometimes with a transmission attached.

Not sure a diesel goes for that.

 

[Josh00333]

Correct Jeep rightfully will, and Magnusson will take up that warranty with theirs.

Dave's tune I would say is better than maggis as he's done more work. However I would say MOST folks with a maggi 3.6 are not running Dave's tune. This is a echo chamber as all forums are. Reality is different.

I'll run the maggi tune and see how it runs. In the future if I feel I need to change it I'll reach out to him. I suspect it will run fine. Which even Dave at times has said the revised maggi factory tune is a fine tune.

 

[DAVECS1]

Maggies current tune is a useable tune. Should be safe for most conditions. Not sure if they set it up for work like I have, but how many people are using their truck as a truck all the time. My guess is with their tune ot will do 85-90 percentof what it used to just fine. It wont be pretty, or comfortable, bit it will do it.

Me, I could have high tea and crumpets while towing an F250 up an 8 percent grade.

I told myself the same thing when I added my SC - If I blow the engine then I can get another 3.6 or even do the hemi swap at that point . So if u think like this and are prepared for possibly being on your own for a blown engine then dive in!!! SCs are definitely fun on the gladiator and wrt cooling u def run a different weight of oil(RIPP even has u adding an extra quart over factory recommended ) , and adding a catch-can probably isnt a bad idea either .

RIPP was fine on the hottest days in colorado climbing mtns for me... never went over 220 on oil temp or coolant temp . Its just a personal choice SC , diesel , or hemi-swap... all good choices IMO but situation for folks matters.
