Hurricane HEMI?

[rvance]

It is.

Yep!

Don’t know if this only Canadian specification but the 6cyl Hurricane only comes with Start/Stop that can’t be permanently shut off. This adds a layer of engine complication that adds unnecessary maintenance vulnerability. Don’t know for the hurricane but on other Start/Stop set ups need a a twin coil starter that needs automatic replacement after a prescribed number or cycles, over sized battery (lucky to get three years out of it), a plate a/c condenser, electric backup oil pump, a capacitor for electrical backup, etc, all layers of technology that I don’t want. Hate Start/Stop, we chose to drive trucks, don’t want this on my truck and if it’s standard at least allow me to disable it. Should be able to dive deep in the computer and change the disable switch to default on. Any thoughts?

I understand you point but if I was forced to choose, I would take stop/start over cylinder deactivation any day.

Pushed too hard? It’s a half ton truck. My Pentastar can handle 6000lbs at half the torque output.

Now if that inline 6 doesn’t have 7 main bearings or the cooling system is poorly designed or owners don’t know how to cool a turbo after hauling…

"owners don’t know how to cool a turbo after hauling"
Please explain? Apparently, I don't know or wasn't told either.

From the Cummins world. I’ve also read in numerous places that heavily loaded gas engines should follow a similar cooldown time. I haven’t read the new owners manual so there may very well be something similar in there for the 3.0.

Driving Condition Load Turbocharger Temp Idle Time (In Minutes)

Stop & Go Empty Cool < 1 Minute

Stop & Go Medium Warm 1 Minute

Highway Speeds Medium Warm 2 Minutes

City Traffic Max GCWR Warm 3 Minutes

Highway Speeds Max GCWR Warm 4 Minutes

Uphill Grade Max GCWR Hot 5 Minutes

Interesting. Thanks for that info.! Yeah, I wasn't told a word about this and we do tow our 8,000lb camper too "and" the dealership knew it when I got this new 2025 RAM with twin turbo.

I have not looked too closely at the design of the Hurricane engine. I assume that it does not have a 'HEMI' design in the heads. My questions is - could it have been a HEMI? Should it be a HEMI? Does it make any sense in an in-line six configuration compared to a V8?

If it was good for the V8, why is it not good in the I6?

The new 3L 6 does not tow as much as the Good solid 5.7. They did this to save money and make a cheaper engine!

I mentioned upthread, the Ram cools itself even with the engine off by using electric pumps. There's nothing required on your part. The inclusion of stop/start technology mandates it, if nothing else.

In Ye Olden Days, if you shut off a vehicle with hot turbos, the oil sat in the turbo and coked from the heat (imagine your oil changing to tiny chunks of charcoal, and that's a good representation of what coking is). This both plugged oil passages and, obviously, reduced the oil's ability to cleanly lubricate.

Today, your electric pumps will continue to circulate the oil and the synthetic oils don't coke like the older "dino oil" does.

The generic statement is true due to thermodynamic physics. It has been proven repeatedly in past reality.
Wishing it were otherwise doesn't make reality cease to exist.
Ecoboost turbos were shot @ 70,000 miles, engine life is app. 100,000 miles. In an engine 23% larger displacement than the Hurricane.

I'm not sure where you're getting your information about the EcoBoost engines. Even the first gens lasted much longer than what you stated. I have a 2014 F150 3.5L EB with almost 130k miles and it's running strong. So far I've been fortunate to not have the cam phaser issue many of these engines had. Turbo failure isn't common in them either. Also, from your first post in this thread, there is no 3.7 EcoBoost engine. That was their base V6 NA gas engine which was phased out in 2015. The bigger issue by far with the older Ecoboost engine era F150's has been the molded lead frame failure, which is transmission related. Ford has solved the issues the early EcoBoost engines might have had. But your numbers of turbos failing at 70k and engine life of 100k are false.

I read trade mags in the 2000's -.2015 when let go. The engine was much maligned by the professionals, just as their 3 valve 5.4 was.
It is not 'false'.

I know nothing about the 5.4, nor did I mention it. The numbers you gave about the EcoBoost are definitely not true though.

Then you are claiming my memory is false. I'm not getting into a google war with you or anyone else.

I know what I saw. It was not false. I also recall the battle of engine architectures for EPA fuel economy mandates, Ford chose little highly boosted engines, GM and Chrysler (before FCA) chose cylinder deactivation on larger engines.
Fords didn't last, GM's pumped oil (I owned one, so I suppose I don't remember that either?), and Chrysler turned out to wipe cams.

It's all false. Right. Got it.

History shows that what you said is not true. I'm not disputing what you may have read 20 years ago. The EcoBoost engine wasn't introduced until 2011 so anything you were reading back then was not based on reliable data. I'm simply saying that history shows that those numbers (predictions?) are wrong.

Personal observations and cherry picked articles/forum subjects here and there are all anecdotal, plain and simple. The Ecoboost engines aren't perfect for sure. They have had ups and downs (like all modern engines). But they have proven to be pretty solid overall and the assertion that they are typically dying at 70k and eating turbos left and right is absurd. Although your observation/reading of this occurring however long ago may be true in those situations, that does not make it true in general. Most are easily lasting well into the 100-200k mile territory and are generally no worse off longevity wise than anything else on the market right now. TBD but that is the hope for the 3.0 SST. So far we love ours and it flat out embarrasses any NA V8 engine in a pickup out there.

Nailed it, it isn't 1990 anymore. No need for treating a modern turbocharged engine any different from any other motor.

I drive my hemi moderately. When on IH 35 be moving at 80 trying to not get run over. I do not drive like granny pa or floor it everytime. Just feels good to have a decent NA truck.
FTR my son has a 2025 Bighorn and he luvs it. I just made sure to tell him to run better fuel than lowly 87 gas.
Of course I run 89 in my VVT and works for me.

Guess I be lowly BOIRD happy to have heat/AC and tunes and start everytime push dat silly button hee hee.

It is human nature for some people to be negative, or be receptive to it. Problems (negative opinions) are always amplified at a far, far greater rate, especially if it reinforces inherently preconceived notions. There may have been a period of turbo failures on some of Ford's EcoBoost engines as I think back, but I haven't heard much in awhile. Many failures are usually attributed to materials issues, which are later overcome.

Interesting. Thanks for that info.! Yeah, I wasn't told a word about this and we do tow our 8,000lb camper too "and" the dealership knew it when I got this new 2025 RAM with twin turbo.

Running tractors under load all day, turbo or not we always let then sit and hi idle for a bit before shutting them down. At night you could see the red color in exhaust system, when it went black, you where good to go. My last couple tractors where air cooled , I never seen hi temps on them, but the turbos would be red hot depending on the job.
PS this was with mainly non syth. oil and huge old tubos., 1970 -2000 stuff.

Silly me, I wrote this and forgot to hit post reply, Guess I can't do 3 things at the same time anymore. So 2 days later

Charge more and lasts less about sums it up, nobody prices have gone up higher then stelantis and this just scratches the surface, next 4-5 years they will be on an island. Kind sad considering they aren't known for quality with any of their brands.

I couldn't find this the other day, but it looks like the price reductions are here, albeit a little late.
