According to what is stated under the title of the article, 409hp and 775 lb-ft at the wheels. That is 13% drop from what Ford's advertised 475 crank horsepower which is inline with the usual drive line power loss, but the 26% drop from the advertised 1,050 lb-ft is way more than usual. Not sure what happened there.

Of course these are probably not be sustained power levels.

As you've said something is wrong with those numbers. It is highly unlikely that the new Powerstroke is capable of 409 rear wheel horsepower and only a maximum of 775 lb ft of torque. I would put 0 confidence in those numbers but I don't think the lack of airflow through the radiator could account for it as peak torque should show up at 1600 rpm .... so if poor intercooler performance is limiting the engine's output already at 1600 rpm it highly unlikely that more fuel and higher rpm is going to fix the problem.

Nice numbers. The only thing I don't like about Mike's numbers is that his dyno is much higher than others. When I had my F150 EcoBoost, I had his tunes. Several of us on the F150 forum did dyno runs on his tunes and could never even get close to what his dyno numbers. I believe the closest was 40hp shy. Not saying anything bad about Mike because his tunes are awesome. I just think his dyno is overly optimistic.


At 0.25 of the video it was stated they were testing the stock numbers.


It doesn't matter if it is stock or not. Some dynos run higher numbers. It may be due to the correction factors or other things like the type of dyno. The rest of us could never come close to the wheel end numbers that 5 star posted.

5 Star also ran a 2019 on the same dyno this week for comparison. Best numbers for that was 388 and 866. The 2020 has a healthy gain.

Guys, I think the MotorTrend folks read their dynos wrong. Each lower curve matches up to an upper curve, so the correct readings are:

~405hp and ~990lb-ft (presumably with nitrous)
~410hp and ~990lb-ft, but peaking later in rpm, without nitrous

If we go by the number at the bottom of the graph, 409hp and 775lb-ft, that means the curves closer together are matched up, but...

There's no way the PS is making 350 lb-ft of torque at 2000 rpm, but also 250 hp - that's mathematically impossible.

250 hp requires: 250*5252/2500 = 525 lb-ft of torque

If we use the set of curves I proposed - match one from the lower pair to one from the upper pair, then the hp vs torque values match up perfectly.

Am I looking at a different graph? It reads closer to 1000 lb-ft to me, with hp around 405ish.

This is at the bottom of their article:


Not sure if those curves are with or without the nitrous, but on the bottom right of that gaph it does show 409 hp/775 lb-ft on the bottom run, and 523 hp with what appears to be 992 lb-ft on the top run. I am guessing the 409 hp run is stock and the 523 hp run is nitrous.

I edited my post above with more details, see what you think.

Per 5 Stars dyno tests of a 2019 vs 2020 6.7 Power Stroke it appears the 3rd Gen 6.7 PSD is putting down some serious power.

2019 (Baseline)
HP: 401
TQ: 901

2020
HP: 469
TQ: 972

Delta Increase
HP: 59
TQ: 71

Enjoy...

While the power/torque increases are legit since they are using the same dyno to calculate the difference, I would not trust the final output numbers because Mikes dyno tends to read much higher than other dynos. I am not sure if it is due to his set up or correction factors, but none of us on the F150 forum could get close to his dyno numbers. His dyno was always 40-50 hp higher than everyone else in the forum in both stock form and with his tunes.

Having said that then perhaps the 2020 6.7 is sandbagging HP or the transmission is more efficient?

Impressive numbers to compare a 19 to a 20, but you gotta remember that dynos read very different, so the only comparison you can make is truck to truck on that same dyno.

I'm looking forward to the follow up video where they test the 6.2L gas against the 7.3L gas.
