I used to think 250hp on a truck was not enough... Then I got a 450hp car. No need to have a powerful offroader, you want it reliable and "fuel efficient" to stay off road longer. Some guy on the gas station tried to flex his 392 Jeep... I have a 2.3l, I have a brick to do brick things and a knife to do knife things. No need to have a knife shaped brick.

[@SteveMichael]

You used the word "reliable" and I 100% agree. Now can you point me to a time where a Ford 2.x liter has been reliable, say compared to a 5.x liter V8? The 302 V8 from Ford has been proven time and time again, and in a super heavy vehicle like the Bronco, the gas mileage would be very comparable. In my opinion this is Ford being lead by their European guys again. Time will tell on these Bronco's but from what I am hearing the early reports are not good at all on reliability.

[@BigCool95]

And not only that, but the 2.3 alone make more power than a v8 ever did in a bronco. Just sounds bad

[@AzulKav]

Love my 2.7. Nice comparison video :) Everyone (well, that owns a 2.3) seems to think there isn't much difference between the two but driving both I noticed a notable difference in the overall feel/pull.

[@thomblank2915]

Shelby Hall is a desert racer, gets to drive both of em, and has the same sentiment. The wife and I actually have both, and can’t tell a difference if it wasn’t for the 2.3 being louder ;)

Awesome content boys!

[@F9FCJ429]

Greetings from Texas. I have a 2015 F150 Lariat 2.7 FX4 bought new. I’m at 140,000 miles right now. One set of spark plugs. One coolant change. And “20,000 mile” Mobil 1 changes done out in my driveway every 5000-6000 miles. MPG since new? 19.5. I promise you I do not drive for MPG! The 36 gallon tank is good for 800+ miles easy on road trips. It idles perfectly from cold starts, meaning it is not carboned up-synthetic oil helps a bunch here. All this to say that those exploding 2.7 engines were a fluke, caused by an outside vendor screwing up. Based on my experience with the very first year 2.7, coming from a long time die hard V8 fan with a Coyote 5.0 ragtop 6sp manual in the garage, my order is in for a 2023 Eruption Green Outer Banks two door with the 2.7. In a year or so it might get built. That’s ok. I’m a grown up. I can wait for my toy🤠 The 36 gallon tank would have been sweet, though!

[@applebitefool]

There’s a massive difference down around 2500-4500 which is where most of our accelerating is done. The 2.7 is genuinely fast in my Sasquatch especially with premium.

[@007Omega]

I love my 2.3L, When I first compared the two back-to-back. The 2.7 felt like it had more power, but I felt like the 2.3 had a better throttle response. I feel like I have no lack of power, FYI, I also have stock wheels and tires. No plan to ever rock crawl. Being as a commuter vehicle and using it for the Snow and the beach, the 2.3 with ethanol Free 87 is perfect for me. Looking forward to possibly getting the catch can and tailgate table when available.

[@riddecp.2224]

About to order, still liking the 2.3L?

[@jamescaldwell5]

I’ve got a 2.3manual badlands and I love it! I’ve always owned manual cars because I think they are more fun and it feels like a more efficient way to get the power to the road. But I’m curious if you can measure a difference on the dyno? Seems like it’d make for an interesting test video.

[@FloridaDeere]

Nice comparison, that little 2.3 certainly develops some serious torque.

[@Haulass95gt]

My modded eco mustang puts down over 400hp/500ft/lbs to the ground on an unopened long block, bolt ons and a precision NX2 turbo.

[@FloridaDeere]

@@Haulass95gt That's pretty amazing, turbo engines are fun.

[@Haulass95gt]

@@FloridaDeere The key with the ecoboost is really getting a tier 1 tuner, after that it's getting parts that compliment each other. Too many people think that putting the biggest and most expensive parts is going to just instantly give them massive gains.

[@selfoblivionalex6262]

Your comment needs to be posted on The American Muscle site! Agree with you 100% some even try to mod with cheap parts. 2.3 is a fun engine meant for those who love to work and maitnece their cars. Parts are endless

[@BarryMDHo]

Add a $500 Power pack tune for 20% more hp, and a $350 cat back exhaust for 15 hp, and a $900 larger intercooler for another 10% or so power, creeping up to 400hp on that 2.3. Any or all are great options to have.

[@cb2536]

And a K&N sticker another 25hp!

Would have been nice if the Dyno graphs were synced by rpm and not wheel speed. The 5252 rpm crossover points were at different places on the graph. I hate wheel speed Dyno graphs.

[@scottsymons6152]

Would there be much difference if it was a 2-door with a 2.3 liter and a 7-speed manual transmission? Drove a base model with that setup and was pretty impressed.

332 tq 260 hp kicks the hell out of my JL 3.6 jeep at 260 tq 286 hp at the crank. I Drove a 2.7 bronco wild and sold my 2018 wrangler. The 2.7 wild is stock to stock is a way better Daley and off roader.

[@tbthedozer]

Man the 2.3l has come a long way since ‘87 in the Thunderbird Turbo Coupe. Those were rated at 155 HP at the crank. I ever win the lottery and I am dropping a 2.3l crate motor into an old Thunderchicken. Everyone is going to say more power but I had one with a 302 stock and a wet road would get 2nd gear wheel spin. The rear pretty is light in those cars, with 260 Hp that bird will likely let the inner hooligan out, lol.

[@SteveMichael]

And yet the reliability has not increased much at all.

[@josemaldonado9117]

this 2.3 isnt the same one from back then. ford uses mazdas 2.3 and has been improving it since

Finally

[@DaveP92329]

It's too bad you didn't display the curves versus RPM instead of road speed. Further, I think there's something incorrect with your results since BOTH show rear-wheel torque numbers equal too or greater than their ratings at the flywheel (325 & 415). There SHOULD be SOME loss through the drive train, although the HP numbers are about 11-13% less (300 & 330). My numbers are from Ford's 2021 brochure.

[@mpeugeot]

I miss having a dyno! Was the 2.7 on 93 octane also? Now do power to weight ratio of the 2 door vs 4 door.

[@IAGOffRoad]

Yes both are on 93

[@kona2day]

Awesome video. Could you possibly post the actual results. Also, did the 2.7 use 93 octane as well?

Couldn't really see the numbers on the screen.

[@codydonovan7356]

The tire size and gear ratios of these two trucks are completely different. I test drove a 2.3L manual with 4.7 gears and 35's and it seemed to have way more power than the 2.7L outer banks with the stock 32's and 3.73 gears.

[@gilbertferguson1685]

Thanks for the information. Is there a big difference in average MPG between the two engines? Not being an engineer, I would think the 2.3 would have to work harder to move all that weight, however the 2.7 would require more fuel to generate the extra power. Might be a toss up. What do you think?

[@tonytee2215]

I have to think the only thing most people will notice between the two is the price and gas savings.

[@Jv19979]

Mine gets 19mpg. 2.3 manual transmission

[@johnrossi6212]

So Ford must be underrating the 2.7 compared to what the Dyno says

[@Bagel_Biscuit]

Is the 2.3 enough with the 4 door sasquatch package ?

[@outlawedmedia4336]

That's what I have and it's plenty! However if you need that acceleration pull at a green light then the 2.7 is better suited for that.

We only run 93 octane in our Broncos with them being turbo. The ECU will adjust the power depending on the octane.

[@concertscoastersandnitro725]

Which engine will live longer the 2.3 or the 2.7

[@Jv19979]

The 2.3

[@matts6551]

2.7 because of MPI (dual injection). Direct Injection only leads to carbon buildup. Even with walnut shell blasting, catch cans, fuel additives you will still have carbon buildup eventually which will lead to long term issues.

[@chrisescue6555]

Talks about oil separator not negating horsepower... then dynos them with totally different wheel and tire sizes. Why not just swap the rears? Your dyno adjustments account for rotating mass, rotational pull, unsprung weight, ground speed differences? Nah.

[@mikeriv60]

Just add the tune to the little 2.3 and will be fine for 99% of the people but theres always someone to say..no 😂 These aren't fing race cars.

[@DEEZEEMTB]

Really love the look of the Broncos. However as a guy who likes to keep his cars for a long time (my Lexus GX470 has 240K miles) there is no way I would get a turbo….especially a Ford.

[@SteveMichael]

I feel the same way. I was told in the 80's how great their 2.3 liter engine was in the Mustang, but it was bad. Then in the 90's I heard this new 2.X liter engine is not at all the same and it is great! It wasn't, it was horrible. The same goes for the 2k and 2010 and now we are in the 2020's. If Ford makes and engine and it starts with 2 and ends in liter, I will pass. Why on Gods green earth they didn't offer a 5.x liter V8 in these boggles my mind. Nobody that buys one of these cares about gas millage.

[@josephjenness6956]

They’ve been using them in police cars for over a decade so they can’t be that unreliable

[@mpeugeot]

my 1st gen 3.5 ecoboost has 250k miles on it and my less than year old 2.7 Bronco has 30k miles.

[@Haulass95gt]

74,000+ miles on my 2018 2.3 Mustang that makes over 400hp to the ground, it's not 1980 anymore.

[@BarryMDHo]

Synthetic or semi-synthetic oil, changed every 5,000-8,000 miles, keeping the air filter and engine/radiator/intercooler clean, as well as letting the engine idle for a minute after hard/hot driving, will significantly prolong engine and turbo life. Also, make sure the automatic engine cooling/heating shutters are operating within specifications too. Oh, and because the 2.3 is direct injection only (no port injection to provide spray/lubrication on the valves) watch for carbon build up on the valves - good qualty fuel, and regular oil changes helps. 2nd Oh, let the engine warm a bit and to get to operating temps before driving, especially before hard driving...ok, that's all. 😁

[@garyzimmerman8679]

How can a Dino be accurate when, it doesn’t include air resistance? Something you get when u drive down a real road but not on a dyno?

[@bordfronco]

It don't need a V8 it's got perfect power 2.7 is what I have I don't need the v8

[@mustangmike418]

People are so dense, "OMG IT SHOULD AT LEAST HAVE A V8" Why exactly? So it can sound better??? The 2.3 and 2.7 both will absolutely decimate the old 5.0 and 5.8 pushrod engines, in every single category. Hell the 2.7 makes more torque than the Coyote as well, and it makes the torque where it should be in a truck/suv....DOWN LOW. Ive had coyote mustangs and now have a 2.7 EB F150 crew cab, and I can for sure tell you, I would definitely rather have the 2.7 in my truck. The coyote is GREAT, but not the best for truck duty. People really need to let go of the Neanderthal thinking of everything has to have a V8 to be good.

[@tonydushaj3912]

I agree with all of that BUT, the sound of a V8 with a nice exhaust is the best music you can possibly listen to. I had a 700 hp coyote with Roush exhaust and I have a 2.7 F150. The coyote is just flat out funner to drive because of the amazing sounds it makes and you don't have to worry about replacing turbos down the road. We make the 5.2 supercharged v8 for the Raptor where I work because people just don't like the sound of the 3.5 raptor which makes plenty of power and decent gas mileage.

[@mpeugeot]

I almost agree with you 100%, but it should have the 3.5 ecoboost.

[@izuksammy]

The 3.5 would have been better. Yes, those engines make awesome power but they are under a huge amount of stress in doing so.

[@ian5.011]

I rather have the v8 for n/a. I don’t like the idea of wheeling with a turbo. But I didn’t have that option on my pallet so I got a 2.3 7 speed. If they made a coyote, I would’ve got it even if it made less power than the 2.7 just for longevity, and no turbos to suck in water. 🤷🏼‍♂️

[@dynasty2295]

Reliability is huge for me. A 5k lb vehicle will stress a turbo 2.3/2.7l engine more than a bigger displacement 5.0. I'm not big into sound but if I want my bronco to last a long time a small displacement turbo isn't it.

[@Really10801]

Where on that dyno chart does the 2.7L have the catastrophic failure I've read so much about ? Too many problems with the Bronco, I was all in on buying one, but I will stick with my 150, Ford really fcked this up. I hope this is not a sign of things to come from Ford.

[@skidmorep13]

Issues with the 2.7 was a bad batch of valve that were incorrectly heat treated. Shouldn't be an issue in the future. Could have happened to the 2.7l f150 as well.

[@mpeugeot]

I have a motor in the middle of the group that is blowing up, they are not all bad, and I say that now with 30k miles and 0 warranty issues. Did I get lucky, probably, but it's blown me away how good it really is. I also have an F-150 and I have not gotten rid of it either.

[@Bacnow]

Lol! That 2.7 was powering F150s way before the Bronco was ever announced to the public, with no complaints! In fact, it was (and is) considered to be an incredibly stout engine capable of handling Insane HP and boost numbers! Like Paul Skidmore stated, it’s a bad batch of valves from a vendor that was obviously effected by the perfect storm (peak of a worldwide pandemic + insanely high demand)! Ford actually did a great job with this vehicle! BTW, i’m a Honda/Toyota guy and have never been a Ford guy! The Bronco will be my first Ford and the Lightning might be my second!
