Fords new dual injection strategy is quite ingenious and goes like this, the Port injection is fully operable, at all times. The RPM at which it starts to be added to by the Direct injection is dependent on engine size and load. The basics are if your piddly putting around and staying out of a load on the engine (think turbos spooling in) the Port injection will be handling things. You push the engine and the Direct injection comes on and starts adding in fuel. Ford says this phase is normally in the 2000-3000 rpm range. At full hammer down the Port injection is still active but only supplying around 5-10% of the fuel based on engine size and load. Ford was addressing several issues with this operating strategy, carbon build up and the dreaded low speed pre-ignition which is more prevalent in turbo charged engines, probably more so with the newly designed turbo. My thought is this new twin scroll turbo (which the 2.7 and 3.0 do not have to my understanding) puts out quite a bit more and comes on faster than the old style, especially for it's size and it helps prevent the ecoboom scenario from turbo charged engines. We also get modified cylinder dimensions, modified cylinder head, improved valve specifications which all translates into better airflow and power. I think future tunes for the little guy are going to be tremendous and look into adding 40-50+ horsepower safely, maybe more but we will see. Enjoy the ride folks!!

Unless I'm misunderstanding this except from the Ford site, since 2024 the 2.7 and 3.0 both have twin-scroll turbos...

"Ford revamped the Ranger’s engines last year to deliver better performance, improved fuel economy, and a more refined ride on any road surface. Options include a reliable 2.3L EcoBoost four-cylinder, a muscular 2.7L EcoBoost V-6 for more power, and a fierce 3.0L EcoBoost V-6 exclusive to the Ranger Raptor. Direct fuel injection and twin-scroll turbochargers provide impressive power when needed while maintaining decent fuel economy during normal driving. Each EcoBoost option pairs with a smooth 10-speed automatic transmission".

Thanks for the clarification. I reached out to Ford engine tech in another city I know and he verified the 2.7, 3.0 started using the twin scroll turbo but not the 3.5l. I'm glad I don't know everything, I'd be hard to live with! Lol

The 3.5L ecoboost has had port injection and direct injection since 2017. Nothing new or ingenious about it. Twin scroll compressors have been around for years as well. 2.0 Eco has it as well as the others listed above

We are talking Ford Rangers. Ford has had the twin scroll since 2015 and as progress is made the technological use and ECU programing has changed to make better use of it also, just ask a Ford engineer. Otherwise they'd be out of a job. Port injection as been around since the 80's has it changed, you bet! If you don't consider something ingenious and progress, making something better yourself would speak volumes! Anyone can have an opinion just like pennies!

I can't see how you would plumb twin-scroll turbos on the twin-turbo 3.0L... So I'm betting the 3.0L does not use twin-scroll turbos.
Don't know about the 2.7L - is that a twin turbo or single? If it's a single then sure, twin-scroll otherwise same logic applies.

Ok CrustyNoodle your giving me brain overload here. That's an interesting thought as the even exhaust pulses for a twin scroll turbo would be missing unless you plumbed exhaust from one side to to others opposite turbo and before the turbo inlet for ultimate efficiency and an even, steady cylinder exhaust flow or a third turbo and or like you said a single turbo They could have just used a single cylinders exhaust pulse for one channel and a two cylinder pulses for the other with channels being of different size for volumetric designed efficiency but still would not work as well as an even split exhaust flow, as the pulses would not be timed as well during the firing cycle or order. So far all pictures I find of twin scroll turbos show even chambers though. The 2.3l uses the exhaust into twin, even streams ( a V8 also) of exhaust but the V6's would always be one short! Time to talk to a engineer, Lol! Time will tell the answer as sooner or later one of these motors will need to be taken apart. Jezz man you need to supply aspirin with thoughts like that, kudos! LOL!

I just got off the phone with ford and they told me point blank that the 2025 ranger and raptor 2.7 and 3.0 have both multiport and direction fuel. They are sending me a confirmation to that effect. I have been looking at a 2025 raptor ranger but doing my research. I am a current own of a 2020 explorer st.

The dealer told you this? That the 2.7 has port injection as well as direct injection? I'd love this to be true, would like to see confirmation. According to this, the 2.7 is DI only (go to 4:04). Does he not know what he is talking about? Is he a bonehead? Hoping so.

The 2.7 has been dual injection since around 2017/18. I was under the impression that the 3.0 is still only direct injection though.

Yeah I just read the comments on his video and he was called out on it several times but still won't change the video until someone provides proof. I'm just glad to know I have multiport when all along I thought I had DI only after watching that video a while back.

I haven’t taken the time to watch that particular video, but if he’s saying the 2.7 is only direct injection, he’s clueless. Ford introduced dual injection with the 2018 F-150 2.7 and everything since then has used the gen 2 engine. You can breathe easy my friend.

For the 6gen Ranger, the 2024 2.3 was direct injection only, but as of 2025 it is port and direct injected. The 2.7 has been and is port and direct injected. The 3.0 has been and is direct injected only.
