How Much HP Can Ford's 2.3L EcoBoost Engine Make? | Same engine as Focus RS/Ranger/Bronco

Mountune USA has developed and engineered the highest horsepower 4 cylinder 2.3L EcoBoost Engine--the same power plant that can be found in the Ford Focus RS, Ford Ranger, and Ford Bronco.

We should really collaborate! We made 805 whp with our 2.3 on the old setup! Looking to pass 1k whp with the new setup.

[@independentassesor2630]

Hi Jessie, how much power and boost can the ecoboost motor handle before it needs the block mod kit applied to keep the cylinders from warping? Looking to buy one which has been stroked and forged, however the owner didn't do the block mod as he wasn't aware of it at the time. Really appreciate your help

[@Paper.Power.Politics]

And one year later goals are surpassed!!! Congrats EMS! But this is why I think it’s a Ute mistake to build with the 2.3 RS block. The casting is just to weak and badly casted. Was a cost effective way to raise share holder profits by using a open deck weak casting block.

I curious to get some feed back from an expert. What are the hp and torque limits for a 2.3(ranger version) with stock internals and block? Also what are the limitations to the stock internals and block that require upgrading? Been loving my tuned ranger!

[@sullyFL]

Would really love to see a reliable 550 HP manual 2.3L bronco build with pistons and rods and dry sump.

[@bobman717]

Would make for a perfect sleeper F-150 or Mustang

[@captaindavidjones844]

I wish you guys would make one for the 3.5L Ecoboost. That would be amazing!

[@mrhappy8966]

Jiminy Christmas is that stock rods pistons block with bigger turbo fuel management? I would be happy with a tune that made as much as the v6 eco boost stock everything.

[@anthony_sasquatch8056]

my favorite company for 2.3 goods!

[@RottenTomahoken]

So at 29 psi it made 684 on di. So was that the limit for the di configuration could handle on e30? Like is it the stock pump and injectors or the new pumps that are all the crazy. Just seems odd that a nx2, 2000xid, a 615 pump, and a turbosmart wastegate. Get very close to that also on e30 to e85.

[@mchristr]

I'm curious about the engine management. The AFR was rock solid all the way through the pull.

[@brianwiegand8073]

Impressive. I wonder what the numbers would be for a reliable daily tune.

[@epantonio94]

@mountune How much hp can make the focus st short block that you guys have?

[@sumplepurple92]

Can u guys do this on my 2017 ford explorer 2.3?

I want to put the 2.3 stroker in my ST can we see similar numbers?

What did this you back i want one for my ranger🔥

[@migsmigs87]

Do you plan to make a kit with the EFR 8374? Twin scroll? Looks like you are hitting full boost at around ~4200 rpm.

[@RottenTomahoken]

Full boost already has on out for a cool 7k another 5 for a built bottom end

[@SVTZ-pq1hf]

Has it blown up yet? I’ve got 300 miles on my sleeved 2.3 and everyone saying it’s going to blow because it’s not 2.0 liter . Personally I think the 2.0 is just a money grab for builders to mass produce short blocks . Considering it takes a lot of time to machine and sleeve or even put CSS in a block . Btw my 2.3 blew at 30k because one of the cam bolts came loose and it jumped timing . 2 rods shot out , big ol windows on either side of the block. I’m having a feeling poor assembly is the reason for a lot of 2.3’s blowing. So wouldn’t doubt mountune could push a stock block that far if they actually tightened their bolts.

[@mdd1963]

"big ol windows on either side of the block" User installed crankshaft inspection windows!

[@4touchdowns1game29]

Damn man that sucks how much power are you making? You can check out mine on my channel mine dynoed at about 400 to the wheels and 460ish pounds of torque on E30.

[@tendyedits1272]

In the mustang ecoboost world the big reason the 2.3 aren’t used as much is because many of them still carry the open deck design as opposed to a closed deck.

[@4touchdowns1game29]

@@tendyedits1272 yeah kinda sucks ford did that. An aluminum open deck block is better for power, cooling etc but only up to a certain point. Give me a semi closed iron block, I don't care if it's heavier, less effeciant.

[@4touchdowns1game29]

@@tendyedits1272 check out my mustang on my channel. I'm basically trying to keep my car safe but be a daily driver. I don't drive around on my e30 tune all the time. Blowing the block up scares me. When I get the time and money I will just do the escape/focus/fusion/maverick swap. They all run the 2.0 that's semi closed and it bolts right on to the 2.3. most people don't know the rs motor in just a 2.0 motor that Ford stroked to get 2.3.

This makes me wanna swap my old fiesta engine to an ecoboost. Note its not even the ST version.

[@x58evo2puma7]

I had a fiesta st I made 383hp on stock engine

[@Ebacherville]

Love the power of my stock 2.3 in my Bronco.. for trail rig , yeah its not 500+hp, but its plenty for a off-roader. I have a C8 corvette, I would never want that HP level in the bronco with a soft suspension and lifted 4x4 its a recipe for disaster IMHO. But could be amazing for the Mustangs.

[@officialmew1127]

Also, bring back the blue cold air intake for the Focus ST and I will buy one from y’all so I don’t have to buy from someone else.

[@MountuneUSA]

Those were limited run and will likely never be produced again, sorry :(

[@officialmew1127]

I’m confused.. I see people talking about OEM blocks only being good for around 450 HP. How is an OEM block able to hole up to such HP? Non car guy here and just bought a Focus ST

[@Prolly_tyler]

Its a mountune block

[@officialmew1127]

@@Prolly_tyler We have a Mountune here in Cali and the guy at Mountune said they use OEM blocks. That;s why I was confused because I heard the OEM blocks are good for maybe 400 to 450 HP. Sorry, Not a motor guy when it comes to building engines.

[@MountuneUSA]

It is an OEM block--but the assembly is completely built out by our engineers and engine builders.

[@kevingeezy5176]

just a guess... the block and heads are aluminum, but the cylinder bores likely have sleeves made of something harder like iron or steel. along with whatever other mods they make i imagine they make upgrades to try to keep the block cooled, ventilated and well oiled. so maybe things like a better water pump and oil pump, better breathing heads, etc.

[@mmholling87]

@@kevingeezy5176 they're probably using a girdle to strengthen the block.
