Ford, please. V8 Bronco

[crenca]

You're trying to solve a problem that doesn't exist

It's not a problem, it's an $opportunity$ for Ford.

As much as I appreciate turbos because I live in and wheel at altitude, I'd still buy the 7.3

I probably go for the coyote too, but it's not as good a fit for a Bronco or any truck as a larger displacement traditional V8 is.

I love a nice V8 as much as the next guy but the 2.7 is worlds better than a coyote from an engineering standpoint. It has less moving parts, it’s the only CGI gas engine block in the world, forged everything, direct mount turbos, etc
It was entirely overbuilt and makes almost the same power at basically half the displacement. I’d argue to say Ford was going to use the 2.7 to replace the 5.0 if they were forced to drop V8s

Not everything is forged. The pistons themselves are cast aluminum. That said, In 2021 and up 2.7L engines Ford added beefier pistons, piston oil cooling cooling galleries, and a more robust crank girdle. There's a sealed motor 2019 2.7L F150 with 650 WHP that has been running for the last 3 years with Stage 4 CRP turbos pushing 33.5 psi of boost on E85. Technically the 2.7L in the Bronco should be able to hold more HP/TQ. Learnings from blown 1st and 2nd gen 2.7L's and the 3.0L found in the Explorer ST show the rods and pistons appear to be the weakest link then followed by the main caps lifting and walking around in high torque applications. All of these issues have been improved in the 2021+ 2.7L and the 3.0L found in the Bronco Raptor and Ranger Raptor.

You think people are clamoring for a mustang with 50 fewer hp?

But with 60 more ft lbs of of torque at about 1000 lower RPM.
So yes I think they would.

 

[Rivers90]

Maybe a factory 91+ tune would make that up?

Also, those who keep track, is the 7.3 an aluminum block? Is it lighter then the coyote?

The 7.3 does have 60 more ft-lbs of torque then the 5.0

As to weight they are about the same 580# and 592#

The 7.3 is narrower and shorter then the 5.0, it is taller though. But both engines are closes in size so either should fit.

The 5.0 gets a lot of its larger size from the heads being double over head cams making them bigger.

https://mountuneusa.com/products/7-3l-super-duty-truck-engine $8,312.45

https://mountuneusa.com/products/5-0l-gen-4-coyote-aluminator-sc-crate-engine $14,249.95

The 7.3 is a lot lower cost too.

Ok, enjoy going slower in your less powerful mustang?

The 5.0 can light the tires up just fine as is...

You will NEVER see a V8 option for the bronco. Ford is doubling down on electric, they killed the edge to make room for a future electric platform. They just invest billions in the Tennessee plant....that ship has sailed at ford.

As much as people clamor for a V8, I think this is likely the correct answer. I don't think the Coyote V8 is the right answer for most Bronco applications. 392 for Jeep is an easy call. The engineering already existed for the platform. Ford doesn't have the engineering done to mass produce a V8 Bronco. Who knows how long CAFE standards will even stay dead? They're not going to risk expending all the money to get a V8 Bronco up in production, then have the Govt pull the rug out from under them, and be stuck with the developmental expense for a vehicle that is never going to be a big volume seller anyways. I just can't see Ford making that choice, particularly when it's an emotional choice.

When people are confronted with a 100k option for a V8, most folks are going to buy the twin turbo V6 anyways and Ford knows it.

I would still want the 7.3 over the 5.0

The 7.3 is more classic muscle car and the 5.0 is more race car. So I understand why people would want both options.

• Torque delivers strong acceleration and pulling power from a stop, while horsepower determines a vehicle’s top speed and sustained performance.

Don't count out the importance of torque too fast.

Your bolded is just...a gross simplification.

If you assume (and I do) that the 5.0 mustang is already capable of breaking traction at launch, or even going wot at say 10mph, what is the benefit of more low end torque?


Edit - if you want to say there's a benefit of subjective things like sound or ...liking ohv engines, then sure, that makes sense.

Who knows how long CAFE standards will even stay dead?

My read is that CAFE 'jumped the shark' politically (and technicaly but that's another discussion). Being leveraged and abused to force EV on everything did its model in, and whatever happens politically in the future it will not be able to simply come back in more or less the same form.

This means that practically Ford can take plan on V8 and other ICE solutions ( which are the future for the next 50 years at least) in ways they could not before.

If you are using a normal transmission auto or manual as you are acceleration and shift gears the RPMs are changing so your engine is not always at max HP or max torque. With each shift the RPMs drop because you are in a higher gear and then start climbing until you need to shift again. So with each shift you may end up below max torque and will not be accelerating as fast as if you were at peak torque. So in general you want the peak torque and peak HP to be far apart in RPMs so you never leave the RPM range between them even when you shift gears. So peak torque at a lower rpm is good and peak HP at a higher RPM is good and more gears to choose from is good too. Back years ago with only a 4 speed the wide power band between torque and HP was really important now with 6 or 10 speed transmissions it is less so but it still matters.

In realty both engines are faster then I need and I would be happy with either.

Subjectively I would love an old fashion pushrod v8. I don't think a 7.3 would count as a big block engine, if it did this would be extra cool because the last factory big block v8 was in the 1970's. The 1973 Mustang cobra 429 and nothing over 5.8L after that I think. The charger dropped the big block v8 after 1974.

This is incredibly false and misleading.

Horsepower can’t be measured. Torque can. Engines make torque, not horsepower. Horsepower is torque over time. It has to be calculated.

For me the choice was a no brainer, The 7.3 445 V8 is antiquated design, basically like a big caveman with modern clothing...pushrod engines with only 2 giant valves per cylinder, Can't rev and if they do they wear out parts VERY quickly.... I like engines with as broad power range and as many RPMs as possible. I also don't care for cast Iron blocks. The 7.3 is however, a great value. because you can find them DIRT CHEAP for the OEM 430hp version... Unless your spending 3 Xs more and get the $26,000 for the Megazilla 615Hp version.

The 5.2 predator can rev to 8,500 RPMs while still having the low end grunt of the 7.3. Obviously the supercharger helps with any altitudes, and the variable valve timing is superior in every way. (The Godzilla cant alter overlap and megazilla deletes vct) 4 valves per cylinder has far more volumetric efficiency and needs less valve lift to make same power.
The drawback is NOT the size difference, or weight... but the initial cost of the engine itself. I got lucky to find one at less than half price, after searching diligently for a year.

 

[turbo_jimbo]

And I’m sure that’s the best v8 ford offers for truck use.

 

[Rivers90]

For me the choice was a no brainer, The 7.3 460 V8 is antiquated design,

The 7.3 and the 460 are two totally different engines. They share no parts and are not in the same engine family.

The 460 is related to the 429 and both came from the ford 385 from the 1960's

The 7.3 L gas engine was a clean sheet design. Not related to any other ford engines before it.

oh I'm fully aware...I just stated 460 to show newbies the cubic inches...and to let them envision an antique.
