392 Gladiator V8 Hemi confirmed by Jeep CEO!

You can't just run a piece of equipment to a shop, and if you could, it meant down-time into the weeks and that can't happen during planting or harvest. And if it broke in the field, you fixed it in the field. Welding, cutting, fabricating, building, engineering, you had to do it all.
I bought 6 row planter dirt cheap because it was a 36" row planter and no one was planting that row width and more save for a very few really small farms. The standard at that time was 30. So I had to use some math and move things over, shorten bars, reconfigure the markers and in the end, had a 6/30 planter and no one knew the difference. It sold like any other 30" planter on my auction, although by the time, 12 row was more standard. Had it been a 36" row planter, might have gone for scrap. I had too much power in my big Case tractor and the front end was a bit dicey at times, so I moved the front axle forward, longer wheelbase, more stable with a heavy load on the rear.
You are a plumber, electrician, builder/remodeler, machinist, you name it.

Absolutely % craziest thing I ever seen my Dad so was we had a top roller bearing go out on his big round bailer. The bearing couldn't be had for weeks. It mounted on the outside of the body/frame of the baler Dad went and found a piece of white oak took the bearing case traced it ,cut it out on a bandsaw measured the shaft on the end of the roller drilled a hole in the center to match then drilled a hole sideways down to the shaft location screwed a grease zeark carefully into the drilled hole found longer bolts and mounted it . And we greased it between every single bail . It wore down about a 1/4 inch by end of the day but it got us through a tight spot . Once that hay is down kicked out windrowed and ready to bail it has to go up.
Sometimes a really dry hard piece of Oak will save your ash. True story by the way.

Fun, someone asked elsewhere, improved 4xe trans on the JL begins build in Feb

I wondered about that. So if my wife wants to trade for a 2026 reign 4xe, wait until Feb - they say reign is late availability so hopefully it will be say, March 2026 or so for the color.
I was hoping her next one would be with that new transmissions from ZF.
I've heard some about the reality of it from a woman who works there (ZF), not to mention the glowing articles about it elsewhere.

So, slow day because one little factory in New York is apparently the lynchpin of the entire industry... Took the time to learn the build planning EDI system, and here are the scheduled builds for LB, JL, JT, and DT through the end of CY 26.

Each chassis I then grabbed the engine option.

This is going to be my last update on this, since it's really a wasted effort and there's probably 35 posts on this board in the past 24 hours about waiting for the 5.7 right now lol.

Damnit, I missed the update. Ugh, if anyone grabbed a screenshot of it can they DM it to me ? Thanks

Nice guy this “someone”.

Jeep just released the info. On the 26 Grand Cherokee and the engine lineup which is what I’ve been waiting on.

Just saw on another utuber that the 2026 Grand Cherokee will be offering the Hurricane engine….

but

it will be a 4 cylinder Hurricane engine…that still makes more juice than the 3.6.

 

[smlobx]

And here it is on the Jeep website..

Is the new EVO Hurricane still a DOHC or Multi-Air the 2.0 Turbo Alpha Romeo?

And here it is on the Jeep website..

If you can do an image search on the forum, you'll find the first half of that image was in another post last week. Apparently the thing has been in the works for a while in the Grand Cherokee, and it was show to have a far better torque curve, coming in sooner than the 3.6. Makes sense - a turbo can generate more low end than a NA engine

It's heavily tweaked from the original 2.0 Hurricane.

While the head design is a modern twin-cam layout with four valves per cylinder, the Hurricane 4’s fueling and ignition systems are where things get interesting. It uses both port and direct fuel injection to balance efficiency and performance. During light loads, the engine relies on port injection for smooth operation and lower particulate emissions, while both systems engage during acceleration and peak power demands.

The engine's real party trick is the introduction of Turbulent Jet Ignition (TJI), a combustion system originally developed for Formula 1.

This system uses a small pre-chamber machined into the head. When the air-fuel mixture compresses, a portion is pushed into the pre-chamber, where it ignites first—each cylinder has two spark plugs, one for the pre-chamber and another for the main chamber. The resulting flame jets through a series of fine orifices into the main combustion chamber, creating a rapid and nearly complete burn. The concept borrows lessons from Ferrari's Formula 1 engines and Maserati’s Nettuno V6, but Stellantis has adapted the process for large-scale production and longevity.

The engine runs on the Miller cycle and achieves a 12:1 compression ratio without pre-detonation, even on regular 87-octane fuel. That, combined with its turbos and twin fuel injection setup, offers flexibility across a wide range of driving conditions and vehicle applications.

“Someone” may also go by “SWIM” sometimes.

The Hurricane 6 would have been a rocket in the GC but I’m good with the numbers this things putting out. The party truck is going to be if it’s reliable. I saw one video of the long block on a stand and it appeared to have a large bore down low thru the block. I think it’s for a power steering rack. Kinda makes me wonder how easy that will be to work on. I did see a metal spin on oil filter on the bottom of the engine though which I personallly love.

pre-detonation,

There's no such thing. There's that term again that keeps getting repeated.
It's either pre-ignition OR detonation. They are two different things although pre-ignition can lead to detonation.
I suspect that was written by someone at hemmings or one of the car blogs.
These car blogs and magazines dumb down the auto world..

We have higher compression ratio in the V6 - but the dynamic compression pressure is what matters. The "compression ratio" is a theoretical number based on comparing a volume of a cylinder at BDC to the volume at TDC. However, that can be changed by valve timing and other factors.
An engine with a 11:1 compression ratio TDC to BDC can actually achieve higher compression pressures than what the mathematical number is based on scavenging, valve timing and other factors.
"Dynamic compression" is what's important as these 4 valve/cylinder engines can easily achieve over 100% pumping efficiency (don't you wish your air compressor did that).
I've seen numbers in the 114% range.

So 4 cyll, 4 valve, 2 L, twin turbo, 8 spark plugs, probably over 300HP. Avery simple unit. What could go wrong.
