Pics of the new Hurricane twin-turbo I-6 engine live at Stellpower

Spark plug change will be, interesting.

Probably no worse than the current 3.6L Pentastar that has you remove the intake to get the drivers bank spark plugs out.

I only see one cold side pipe coming out of the intercooler so it appears the two turbos both pressurize the plenum that sits below the hot pipes side of the IC effectively both just working together to realize a load or boost target.

Yep. It'll be a PHEV with the Hurricane. At least I have a 2022, so it's not the very next year!

Right, but then again there's no plans for "electrifying" the JT per Daimchrysliatantis Motori AG but that doesn't rule out a 4Xe Gladiator. And I'm not ruling out a hybrid, either.

My bigger concern aside from legendary Mopar reliability is the payload and towing. I was all about a diesel until I saw the capacities went down due to the weight.

I would love that straight 6 without any turbo…..

My past vehicles were eco-booms, as you've read in my past posts, I left them for naturally aspirated. Most frustrating when the computer decides, when You're towing, or hauling, ""Engine save" is activated, the turbos are shut down, and your left towing with just the basic CI/CC of a non-boosted engine. All activities done within the weight limits of the vehicle.

Same for me. I wouldn't touch that thing until it's been around a few years. Especially if it's a DI only engine.

The 3.6L isn't perfect but at least it is easy on oil, doesn't have fuel dilution or carbon build up on the intake valves.

Need clarification, are they done calling it Tornado (code name for development)? Same engine??

Yes they are. That was a code name that was dropped from it some months ago when the official name "Hurricane" was officially posted.

the Jeep Gladiator with the 3.6L Pentastar gasoline V6 engine with Variable Valve Timing, produces 285 horsepower, and 260 lb. ft. of torque. The Hurricane engine (is based closely on the 2.0 liter GME T4, used by the Wrangler in standard and 4xe forms) Standard Output puts out 420 hp and 468 lb-ft of torque, using midgrade fuel (like the 5.7 Hemi), the High Output puts down 510 hp and 500 lb-ft of torque, with premium fuel. I thought I read the std output had a single turbo and the high output had the twin turbo… so wonder what the output would be with no turbo. Would it be better than the pentastar? I also saw an article stating they both have the twin turbo - so really confusing.

Pretty sure they both have 2 turbochargers.
I could see Jeep having a 3rd tune option, a ‘Perfectly Adequate Power’ version, 290hp/270lb-ft ?

It would most definitely be worse than the pentastar.

It would need to either make 20% more specific torque or rev 20% higher with no additional frictional losses. Neither of which is likely.

The other thing is that in general torque is a function of engine size.

You can make normally aspirated engines with high hp, but they achieve it by revving. A perfect example of this is the engine in a Honda S2000 vs the Accord.

The Accord made something like 150 hp and 152 ft lbs of torque.
The S2000 made 247 hp and also about 152 ft-lbs of torque.

At between 2000 and 5000 rpm they made pretty much exactly the same power and torque.

The difference was that the Accord stopped making more power around 5000 rpm because the torque started to decrease. The S2000 continued to make torque and power up to about 8000 rpm.

This is exactly the wrong way to make power in a vehicle like ours.

(3/3.6) x 285 = 237 hp

Even if we figure a bit better volumetric and thermodynamic efficiency made possible by direct injection we aren't going to make much more than 250 hp unless we turn the motor faster.

In summary, a 3.0L normally aspirated engine would be a step backwards.

Nice! Looks like it will be impossible to upgrade turbos to larger units …

Probably not, at least not without new plumbing and intercooler.

But then again, with a tune you are probably looking at 550 hp and 550 ft-lbs.

That is probably fine.

Its twin turbo not compound. 3 exhaust ports feed each turbo separately. Very odd. Likely super small turbos to have quick spool up.

 

[Almost]

I think I read one turbo is smaller to spool quickly for the low end, and the bigger turbo will help with the high end once spooled up (hard to tell in the pics). I'm curious why they went this route when everyone else has basically solved this with variable vane turbos. Are these ones VVT? If they felt that wasn't going to cut it alone and felt it was better solved with two it does indicate that low end was a high priority which is great for the Wrangler/Gladiator folks.

 

[Stratus109]

Just from the looks of it, I have a hard time believingit will produce 500hp consistently . I wonder what the intercooler will look like.
