2025 2.3L Intake

[Revolver]

Has there been a release from any company for a Cold Air Intake for the redesigned 2.3L?

No, I’d guess it’ll probably be a while.

K&N 50-2631 NextGen Cold Air Intake - Ford Bronco 2.3L 2025

Looks like K&N released one.

What is going on with their dyno sheet? 184hp and 189tq? Those numbers are way off. Maybe they meant bronco sport. No way we lose 116hp and 136tq to the wheels.

I’m assuming it probably has something to do with the dyno run only being done is 2nd gear, for whatever odd reason they did that

Not to mention dyno type could play a large part.

If run higher than a one-to-one gearing is a torque multiplier...
lower (over drive) would decrease torque

Real world, yes. A lower gear like 2nd will make more torque because of multiplication, but it won’t read like that on a chassis dyno though.

An overdrive gear will always equate to a larger dyno number because in a lower gear, a significant chunk of the engine power goes into spinning up all the drivetrain inertia instead of actually accelerating the dyno rollers.

So in this case, 2nd gear only shows ~180 hp/tq, but in a 1:1 gear it would show more realistic overall numbers.
But at the same time, I would guess it probably wouldn’t change the overall “gains” very much which is probably why they didn’t bother doing it in a higher gear.

.... lol, if a DYNO only measures TORQUE, it doesn't know what the driveline gearing is...


Here maybe you'll get it this time.

Same testing on the same mustang, NOT in a 1:1 gear ratio… BUT in a different gear- TQ Multiplication… and NO the 2.3L ENGINE is not making 840 pounds of TQ
WHY dyno's run 1:1 to tuning the motor... other pulls at other gearing gathers different information...

There is a lot of great knowledge about either versions of Fords 2.3L motor, just not anyone here that has come forward...

AND there is a lot of mustang information on heat sink... while driving, on a race course in the first laps, EVEN driving in stop and go just getting to the Christmas Tree at the Drag Strip...

Even Greyz had to make CHITT UP to not prove a point.

Google AI "what gear to run a dyno in?"
AI Overview


For most vehicles, you should perform a dyno pull in 4th gear, as it is typically a 1:1 direct-drive ratio. This gear provides the most accurate power reading with the least parasitic drivetrain loss, while allowing the engine to sweep slowly enough for the tuner to gather precise data. [1, 2, 3]
Choosing the right gear balances accuracy, traction, and the duration of the dyno pull:

The 1:1 Rule

• Direct Drive: 4th gear (or 5th gear in some 6-speed manuals) usually offers a 1:1 transmission ratio. This means the engine's crankshaft and the transmission output shaft rotate at the same speed, resulting in the most accurate horsepower and torque readings.
• Reduced Friction: Direct drive minimizes parasitic power losses through the gearbox compared to using overdrive or highly multiplied lower gears. [1, 2, 3]

Why Not Higher or Lower Gears?

• Lower Gears (1st, 2nd, 3rd): These gears create a heavy mechanical advantage that can multiply torque beyond what the dyno’s rollers can handle or cause the car to lose traction. Pulls are also too brief to capture high-quality data.
• Higher Gears (5th, 6th, etc.): While they allow for a steady load, these are typically overdrive gears that force the engine to work too hard against all the rotating mass (driveshafts, axles, and tires), resulting in artificially lower power readings. They also result in extremely high, sometimes dangerous wheel speeds. [1, 2, 3, 4, 5]

Important Considerations

• Automatic Transmissions: Modern automatics with 8, 9, or 10 speeds may have a 1:1 ratio very deep in the lower gears. Tuners usually select the gear closest to 1:1 that keeps the vehicle safely below the tire's speed rating (often 5th or 6th gear).
• Motorcycles: Bikes are typically run in 4th or 5th gear, depending on the number of total gears, with 5th often serving as the direct drive.
• Always verify with your tuner: The golden rule of dyno tuning is to follow the guidance of your professional tuner or dyno operator. They know their specific equipment and can choose the optimal gear to match the dyno's load capacity and the vehicle's unique power curve. [1, 2, 3, 4]

Lmao, calm down chief.

Yes lower gears do multiply torque, which I already said, and is also why the Mustang graph you posted shows stupid high wheel torque numbers. Dynos can be easily manipulated for big flashy torque numbers by just running it in 1st gear and smashing the gas. We all know how gearing works, congratulations.

The actual point was about why peak horsepower numbers (and often torque too) read lower in low gears on a chassis dyno when you’re actually trying to get realistic numbers. The short pull wastes a ton of power on drivetrain inertia instead of the rollers.

Which is EXACTLY what you see going back to the original K&N Bronco graph in question here. Both HP and TQ are extremely low because they used 2nd gear instead of a typical 1:1 gear for accurate realistic numbers.

You took one screen grab from some random graph of a completely different vehicle showing torque multiplication being manipulated on one dyno run and acted like you just debunked anything I said lol

Maybe relax with the smug “here maybe you’ll get it this time” lectures. I’ve actually dynod multiple vehicles including a Bronco in multiple different gears, so I’m well aware of how they work and the results that you could get depending on what gear you’re in or how you accelerate on the dyno.

I think he's gone full retard.

And just like that, I remember why I blocked him. Lmao.

As I inferred… 2 second gear (shifter) would /did improved the dyno numbers… Why they’re just marketing BS when not all is shared.

Keep your day job…

Brian... seems you are the one to dumb ... you DOXX'ed yourself on your post here on B6G

EDITED... you did it I had nothing to do with it... ;^) You had been asked nicely several times to block me, since you cannot/will not stop FKng with others threads.

Brian... seems you are the one to dumb ... you DOXX'ed yourself on your post here on B6G

I won't deny - yeah, I'm pretty dumb. But most people don't care enough to dig around and shouting ENHANCE at photos to dig up someone's address. I mean, my name isn't exactly a secret, I don't hide my VIN or license plate either, and I probably have my phone number around here somewhere too. I don't really feel the need to hide that stuff, because I try not to do things I regret or need to hide online. But, being human, yeah sometimes I do anyway.

But you can come on down, it's cool. I have cold beer. Still have a garage full of takeoff parts. And we can play bad loud music at my bad neighbors. And there are a couple of cool trails just down the road.
