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

[JTDay]

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

Right but both turbos work concurrently to pressurize the intake manifold is what I was saying. I wasn't able to tell from the pics how the turbos were sharing, or not sharing, the exhaust gasses but that's pretty interesting. I wonder if BMWs twin setups did that? I think they've mostly migrated to twin scroll singles but honestly I haven't been paying attention for a few years now.

It does look like both turbos simply feed the same intake manifold where the water to air intercooler resides.

The turbos do not look VGT but I would imagine they will have to be variable.

This engine is very complex with 2 tons of plastic garbage in the intake path that are pressurized and heated by the air and the engine.

Not a good way to go for Jeep. A better solution would be a smaller NA hemi V8 engine (4.0l) and the 2.0l hurricane for the "economy" engine. This thing is way too complex for a rugged vehicle.

I wont be the test mule for this Hurricane...I'll be watching.

Buying any 1.0v of an engine, let alone Mopar is like the video where Donut Media bought safety equipment from Wish.com.

If it was an option to have ordered it with my 2022, I would have done it even on revision zero of the engine. Opinion alert: the pentastar v6 is gutless.

Twin Nagasaki rice cookers, air to water IC, compact looking. Looks like those two smaller turbos should spool quickly and make buttloads of torque and power throughout the rev range. Cool to see how the "exhaust manifold" is just cast as part of the head now.

Where can I buy this as a crate for my 2020 Rubi

The Rams and higher end Jeeps look to receive this powerplant first. Let them be the test mules and then I want one in a JT!

Not new....... check the 3.6 -

they are part of the heads.

How about a stroked 4.0 that can rev to 6200 rpm, make 395 horsepower, and 367 lb-ft of torque?
They are out there — without using a turbocharger or supercharger.

Or this one that does 861/881.

If it can be done with a 4.0 (massively modified) then getting power out of an engine built from the ground up for power and torque from low displacement isn't that big a deal...........

If I recall, Honda has reached at least 120% pumping efficiency with a NA engine.
Creative minds will keep ICE around for a bit longer. It won't be cheap to do, but nothing worth doing is ever easy or cheap.

hell id settle for one of those turbos on this pentastar turd engine ...

I looked up some pics. Interesting. I guess tuned headers aren't a thing anymore on modern engines.

I can't think of a U.S. production car that had tuned headers from the factory. Even Ford, starting somewhere in the 80s, used tubular exhaust manifolds on HO engines, but those were not tuned and not really headers per se.
Tuned headers take a lot of real estate, and need length. There simply isn't space. Not with the converters and so on needed. They are a pain in the butt to deal with (I know - I rigged my own setup with pipes underneath that can be unclamped and unbolted should I need to drop the transmission out) and they let loose a lot of heat very early. That's why many of us wrap the header tubes with with a heat shield material like asbestos.
They must be equal length tubes and the collector has to be designed in a way that minimizes the individual pulses interfering with each other once they reach the collector. Tuned headers also need to be tuned to the peak HP RPM so are really only most helpful at that RPM area.
Then there's the bit of O2 sensors - those are per bank, not per cylinder, so you'd have to have them well down the exhaust stream, past the collector.
Tuned headers are only going to help when everything else is there to back them up, including the rest of the exhaust system, the intake system, the cam(s) and so on.
They are pretty much worthless on a typical engine.

The 4.0 used tubular exhaust manifold, but not really headers although we call it that.
Integral exhaust manifolds have a couple of advantages - no issues matching ports, no issues with leaks where the exhaust manifold bolts to the head (a real problem with bolting to aluminum heads with different expansion rates) and they won't warp or crack.

Exhaust manifold designs do matter - a lot. AMC gained quite a bit with their dog-leg exhaust ports and free-flow exhaust manifold design in 1970.

Tuned headers take space, take money, and turn speed bumps and dead bugs on the road into obstacles to be avoided.

Luckily, unlike some Mustangs I've worked on (Cobra jet 429 hit my memory) and headers, I have no trouble reaching spark plugs............
But these make no difference unless I wind the thing up pretty tight.

Supposedly the original planning design architecture of the Pentastar had both DI and Turbo as a possible later product but nothing has even squeaked out if that would be a reality.

Correct, I have seen that mentioned in actual FCA documents, and ALLPAR as well.
DI would mean having to watch the PCV oil issue, but it would give more power and efficiency to the engine.
