Yeah, you are right and most certainly the 4.0 has more torque from off idle to around 1800rpm. I also agree low rpm dyno testing is infuriating. It gets blamed on the transmission not being able to stay in the 1:1 gear at low rpm or being prone to downshifting, but to me that shows a lack of...

Yeah, so, you know, like, uh, and... I cant wait for the Hurricane to become available in the JT. Everyone can pull out their jester hats and high-step to the nearest "tuners" garage to get "tuned". Then, after half the active forum member have popped their hurricanes from uploading the...

LMAO. It's fun to say incendiary and hyperbolic things. It's more fun when their mostly true... The VM Motori based diesels are excellent but expensive, difficult to attain, and soon to be fully orphaned. This is not a judgment on the engine but rather a product on the guberment gods we...

^^ Taking this at face-value. The rubber is abraded off the tire as a result of friction with the road surface. Those abraded rubber particles then become minor trace components of the roadway dust profile. The water is displaced by the tires until the space occupied by the tires...

LOL. Yeah, significantly more, while also being very energy dense, reliable, and fuel efficient, particularly when compared to its' peers.

Generally, closer to true than false, but many many high HP turbo engines have open decks. The real trouble is that they are not as forgiving when clownmanship tuning and overheating are involved. The benefits of open-deck on well designed and tuned engines are significant.

An actual dedicated snow tire will blow your mind. Blizzak, Winterforce, Hakkapelliita, etc. I'd put them on a cheap take-off wheel set.

I'm afraid there's nothing easy. The Pentastar is not underpowered and already makes more HP and TQ at low RPM, than any Jeep 6-cyl before it. I love the jeep 4.0, but it was a turd --it's just that our memories are short and everything made today has so much power we've lost grip with...

Please point to a single cold-start oil related failure... The big lobe is not engaged at all under 3k RPM, so that is a disingenuous argument. Pentastar have zero other oil related failures. Pentastar don't really fail at all, except as an anomaly. This comical oil drain-back issue is a...

I’ve had the best performance and durability results from Bilstein.

I love the JT. This is my personal experience. I have towed and over-towed with many vehicles over 30 years. My Willys Pentastar ZF tows very well up to about ~5000 pounds. After that weight, it’s the most dangerous tow vehicle I’ve ever used. Has zero to do with the Pentastar or brakes...

Good looking out, Shadowspapa. Uparms, I went with M1, 0w40 Euro. I’ve documented my results in another forum post. Also provided a relatively extended mileage UOA for anyone curious.

Your criminal activities were in the name of science and only very limited, so you get a pass. I also bet you weren't in the left lane...

Also noteworthy, is where the ceramic appears to be cracked or spalling at the plug terminal joint. I agree with the other posters who have been curious about how uncharacteristically wet the plugs appear. Many oddities in this presentation. I'm calling shens.

If the OP isn't trolling, --Oh boy. Your intake is leaking for sure. It also sounds like you may have missed something or broken something else on dis/reassembly. Your Pentastar's operating range is 800-6500 rpm. You keeping it below 2000rpm is destroying it. Engines have to be fully...

Not any that I am acquainted with. The insurance company dongle is a privacy-trade I think you should thoughtfully reconsider. With government and government mandated compulsory "service" sectors, the money is always secondary to the power.

I've never experimented with CO2 in tires, but I don't know that there would be a sufficient amount of moisture in the air to create much acid. I personally may flush it out the next time I did regular maintenance, but I would not worry about it before then. Even for many months. FWIW

Scotty Kilmer is a genuine piece of garbage. All of his lame trash videos are festooned with click-bait and he's a terribly stupid person. If he can't even be honest in his video screen grabs, why would he be honest at anything else? I cant stand that YT puts them in my feed. He is human...
