While some are still wondering whether the EcoBoost Mustang is worthy of attention or not, the aftermarket world is working overtime to take the four-cylinder as high as possible. The latest result? An output that easily plays on the five-oh arena.
To be more precise, we’re talking about 508 HP and 482 lb-ft (654 Nm) of torque. And since these values are for the power at the wheels, it means the four-banger tops the 5-liber V8 of the Mustang GT. For those curious about the new standing HP record this EcoBoost set, you should know the figures come after a DynoJet test with an SAE correction - graphs below.

The tuning job comes from FFTEC and we have to explain this is the stock engine block we’re talking about.

In fact, here is the full list of mods the 2.3-liter unit was gifted with:

Turbo System

BorgWarner EFR8374 @ ~33PSI
FFTEC CylHead/Turbo Flange Adapter
FFTEC Intake System
FFTEC Chargepipe System
FFTEC EcoEconomy Intercooler
FFTEC Exhaust System

Cylinder Block

FFTEC Forged Pistons
FFTEC Forged Rods
OEM Crank
OEM Cylinder Block — No BlockGuard, Sleeves, CSS, etc.

Cylinder Head

OEM Cylinder Head — no Port/Polish
OEM Valves
OEM Valve Springs
OEM Camshafts


COBB Accessport Protuned by our own Calibration Staff

Fuel System

Stock Fuel System
91 Octane Fuel blended with some 101 = ~95-96 Octane

Interestingly enough, it seems FFTEC’s EcoBoost tune brings a broader power band compared to a 2015 Mustang GT. While the stock V8 delivers peak torque between 4,100 and 6,500 rpm, the custom forced-fed four-pot.

As you can imagine, this is an arm-wrestling competition here, so nobody guarantees that applying the same mods to your EcoBoost ‘Stang won’t bring the reliability into the hilarious area. Still, this project deserves our full attention and the dyno video below allows us to get a taste of it.
