7.3L output guesses?

[JExpedition07]

With the 2020 MY coming fast and Fords new 7.3L V8 being the new engine for their all new power wagon competitor the Ford “Tremor” (A Raptorized Super Duty) rumors are buzzing about it. Most estimates are in the 430+ horsepower with torque at or around 550 lb ft....I wish they’d release the specs!!!

 

[Sgt Darkness]

I’m thinking, hearing, reading it will be close to 450hp and 500 ftlbs torque. Nothing real firm at this point on the internet.

 

[JExpedition07]

Ford released it today

7.3L output: 430 Horsepower and 475 lb ft.

Good power. Interesting, notice it produces 400 lb ft at only 1,500 RPM! Ford stresses the durability of it.

Here is an interesting and factual article from the Detroit Free Press: https://www.freep.com/story/money/c...08/01/v-8-engine-ford-2020-pickup/1878556001/

That is one flat torque curve

Found this interesting in the article:

In addition to that, many fleet customers only keep trucks this size for three or four years, so diesel’s long-term, high-mileage durability isn’t worth those engines’ higher cost.

This engine is seriously de-tuned in stock form, but that’s what gives it the insane torque down low. If it had the same power density of the 6.2 it would be about 450 ponies and 500 lb ft, but it would be higher in the band. I get why Ford sacrificed peak numbers for the entire band to be better suited for hauling.

This engine would be a monster with hotter cams or direct injection. It’s running a lower compression ratio and port injection for serviceability and longevity for now. The new GM 6.6 gas is close in torque at 464 lb ft, but it’s strained harder to get it and uses direct injection.

Power density can't really be compared to a sohc engine. The powertrain is suppose to be relatively light for the size. I couldn't get any info on the 7.3 compression ratio, but the GM 6.6 is 10.8:1 while the HD 6.0 GM workhorse was 9.7. I believe the 6.2 Ford is 9.8, which is also a tough motor for a sohc given its cast iron block.

I am glad Ford skipped the DI, cylinder deactivation, and other gizmos in the name of reliability.

Who else would love to see this engine in an Expedition or an all-new Excursion?

I don't think this engine would work for an Expedition. Many Expeditions are used as daily drivers as well as tow vehicles and the MPG would be abysmal in that use case. This engine is designed to produce the best MPG at high loads, meaning frequent towing or hauling. I don't think Ford is going to put it any of their half-tons. I'm very happy with the 3.5 turbo. Only thing that would make it better is making it a PHEV.

Why’s that? It would have less power than the GM 6.2, would it get worse gas mileage than a Denali or Escalade?

I think lots of folks would love a V8 in the expy and navi

Ford engineers are on record as stating that the displacement was chosen specifically to maximize fuel economy at high loads. People with half ton vehicles probably aren't towing at heavy loads very frequently and may also use the vehicle as a daily driver. Yes, a V8 might be popular, but this one would be oversized for a half ton chassis. It's designed specifically for the Ford Super Duty vehicles, which are used primarily for work.

Yep, this is why the 5.4 Triton is a good half ton engine. Not too big, not too small with good torque. Just was time for Ford to do something new. I can get 20 MPG on the highway with my 5.4 and tow 9,000 pounds, good jack of all trades motor. The 5.0 doesn’t have the low end grunt of the 5.4.....hence why it didn’t replace the 5.4 applications.

A 7.3 is big for a lighter half ton but is perfect for a 250. It will be a good engine for towing and daily driving in a 3/4+ ton with the extra curb weight and proper gearing as it won’t be working hard to push the weight around.

 

[cmiles97]

If they make the Excursion again...maybe put that in there as an option. Otherwise Ford is doing well with the Turbo motors.

Did you see what they are going to get HP/TQ wise in the 2020 Aviator?

"the Aviator's hybrid model — manages a whopping 494 horsepower and 630 lb-ft of torque"

Just saying if they can produce these numbers reliably, why put a 7.3 in a half ton application?

i never got more than 17 with my 5.4 in my 2010 f150 crew cab 3.55 gears...and it was horrible at tq..i may have had a turkey. but it was a disappointment. but i was partial to my superduties with tons of diesel torque

 

[JExpedition07]

Picked up a new 21 foot boat today for a little project with the EL, probably around 3,000 pounds. The 5.4 didn’t even know it was there, maybe it’s the 3.73s in the Expeditions. Cruised along in 6th and only downshifted once up a steep bridge to 4th.

 

[JExpedition07]

Has anyone seen the new 2020 Silverado HD? Man that’s bad....
