Let the chatter begin..... 3.0L Hurricane I6 Engine

[The Last Cowboy]

Here's a photo of a Hurricane in a full size Ram 1500 chassis.

Depending on how it’s configured a 392 weighs between 5,150 lbs and 5,450 lbs.

But if you use those weights @azjl#3's numbers won't look so compelling

Rumored to be just 4" longer at the crank vs the 5.7L. Bet it would probably fit myself.

Rumored.

Actual about 6" longer then the 392 engine.
Don't worry, it will be in next years model.

392 is lots of fun ... but I'm probably going 2dr/manual if thats still an option next Jeep.

That driver-side exhaust infrastructure is comparatively large, even when looking at it residing in a light truck frame. I can envision the Jeep engineers putting in some overtime shifts if or when Corporate decides to shoehorn the forced-induction I6 in the next-gen Wrangler.

Or perhaps they'll come to their senses, remember the model's original mission brief, and cool their heels as it concerns the unending consumer bleating for More! More! More! horsepower.

Now where have I heard that before ?

without sufficient incentive to justify cost vs returns for the JL’s remaining production it will not fit………an I-6 even “fit” in a 3B , with extensive fabrication. ….. did you know the Boss 429 doesn’t fit in a Mustang. Ford did extensive fabrication, even moved the shock towers on just enough required “production” models to qualify to race. The incentive overcame the cost. Jeep’s incentive ?

Ford didn't put the boss 429 into the mustang, they outsourced it to I believe Car Craft.

You can mark my words here if you want. If they decide to put the I6 into a wrangler, they will. It will fit.

Sure, they could, R&D, crash/compliance testing, mfg changes time and expense for the limited remaining JL production becomes a cost vs returns management consideration. Possibly- but I suspect they will put it off and design the next gen for it …. My Crystal Ball has been wrong before though…. Just saw an article mentioning the Boss 9 “fewer than 900 ever built”

Can you imagine the heat coming off all of that exhaust nightmare in the already overly confined Wrangler engine space? You think there are high underhood temps now! ?

Hmmmm, nope, you can get a 22 392 for about $65,000-70,000 with under 20,000 miles

Any of you 392ers who got out of a 392, why? I'm trying to get on the final edition list at two dealers, but lb for lb, my 4,000lb 2 door with 260 tq at 15 lb load per ft/lb is pretty peppy and close to a 6,500lb 392 with 470ft/lbs at 13.8 lb, call it 14lb per ft/lb.

Pretty close 0-60...only 43% slower? 6.3s to 60 isn't peppy at all compared to 4.4s. Yes the JL is peppy compared to all wranglers that came before it, but it's a turd compared to the 392.

I know that the torque charts say differently but I came directly from the 4.0 to the 3.6 and I can feel the difference. Some of the difference is probably the ultra-light flywheel in my JL, versus the automatic I had with the 4.0, but it's a night and day difference to me.

Comparing the crap clutch and de-tuned 3.6L (Jeeps fix for exploding clutches) is misleading. The jlur will outcrawl our old wj and pull grades better and it had the 4.7L v8 (most of that is the much improved 8 speed auto). The 4.0L in my xj was a dog compared to the 3.6L. Even the tj was slow and under powered by comparison. Even in the JT (much heavier in factory 4.10s and 37s without the 4-1 tcase) the 3.6L is a rocket on road and will crawl no problem.

A little more, the Barracudas, Valiants, Novas and Mustangs base engines were straight/slant sixes. They had plenty of room front to back from the start.

A generation or two ago Jeep Engineers managed to stuff the 4.0 into the XJ platform when it was originally designed for a V6, so can they do it, probably. What is telling to me is that of all the concept Jeeps that they roll out each year for Easter Jeep Safari, so far the Hurricane has not found its way into the JL Platform. If we go another year without it, then my thought is that there’s a show stopper that they can’t get around until the J70 platform comes.

They weren't able to stuff it in there... they had to lengthen/stretch the jeep so it would fit.

More power is always a nice option, but frankly the same outcome can be accomplished if Jeep offered multiple gear options on all trims and transmissions. My 2021 Sahara 6sp with 3.45 is adequate but far from inspiring, I would have gone 4.10 or even 4.56 if that were a factory option at the time. I know they have some options now but are they not only for the XR package? The new willys coming with 4.10 standard is a good start

Only people who've never driven anything with horsepower and torque think gearing accomplishes the same thing. If that worked you could just slap it in 4Lo and run 0-60 in 4seconds. Go try it (no it won't hurt the jeep to drive on dry pavement in a straight line), it doesn't work that way. Gearing helps to keep the vehicle in the power band, but with the 8spd that's never a problem. The problem is the v6s power comes on high in the rpms and is barely adequate for a 5klb built rig on large tires.
