American Muscles EcoBoost 2015 Mustang Runs Low 12s with Exhaust (Video)
When we first features the AmericanMuscle.com 2015 Ford Mustang EcoBoost back in December, the AM team had partnered with Bama Performance squeeze a little more power out of the turbocharged 2.3L engine. With a cold air intake and a Bama tune, the EcoBoost Mustang ran an impressive time of 12.9 with 283 horsepower and 342lb-ft of torque at the rear wheels. However, the Bama and American Muscle Mustang EcoBoost has gotten another modification to add some power and, as a result, the 4-cylinder 2015 Mustang is running quarter mile times well into the low 12 second range.
The American Muscle EcoBoost Mustang
The 2015 Ford Mustang EcoBoost being used as the official shop car of the Mustang tuning experts at AmericanMuscle.com is fitted with the 2.3L turbocharged 4-cylinder engine and the 6-speed automatic transmission. In bone stock form, this Mustang ran 13.6 in the quarter mile, and that is a mighty impressive time for a drivetrain package designed to be the most fuel efficient muscle car ever.
American Muscle then began adding some extra power, installing a cold air intake setup and a custom dyno tune with the help of the folks from Bama Performance. Those simple mods upped the output to 283 wheel horsepower and 342lb-ft of wheel torque while also helping to cut the quarter mile time into the 12.9 range with the help of some good, sticky drag radial tires. Click here for a closer look at that run if you missed it.
This time, American Muscle has tapped the people at Kooks exhaust to build a turbo-back 3 inch exhaust setup for the EcoBoost Mustang and the results are incredible. When using the same engine tune as they did with just the cold air intake, the AM EcoBoost Mustang with the full exhaust setup turned out 308 wheel horsepower and 379lb-ft of wheel torque. That is an increase of 25 horsepower and 37lb-ft of torque at the rear wheels by just swapping out the factory exhaust for a system that flows better. I would imagine that a custom tune with these components will yield even better power figures, but after the dyno run with the new exhaust, American Muscle and Bama headed to the drag strip to test the real world impact of this new exhaust system.
Deep 12s with Exhaust, Intake, Tune
So, the guys from American Muscle have tested their 2015 Ford Mustang EcoBoost at a quarter mile track near their HQ in Pennsylvania, but when visiting Kooks in North Carolina, they were unable to find a quarter mile drag strip within a reasonable difference. Instead, they took their EcoBoost Mustang to the local 8th mile track to see what it would run.
On the first run, the AM EcoBoost Mustang ran into some boost issues and turned in a disappointing time of 8.27, but after some adjustments by the Bama team, they hit the track with far better results. On that second run, the tuned EcoBoost Mustang with full exhaust and an intake setup ran a 7.91. Using a simple online calculator, that would be a quarter mile run in the 12.35-12.50 range, which is mighty impressive. However, they went back to the line one more time and with some extra shift point tweaks, the 4-cylinder Mustang ran an incredible 7.71 8th mile. Using the online conversion tables, that would lead to a quarter mile in the 12.05-12.15 range.
So with good tires, a full exhaust setup, a cold air intake and a very good tune, the 2015 Ford Mustang EcoBoost with the 6-speed automatic transmission will get you very near an 11 second quarter mile time. Knowing American Muscle, we will soon see quarter mile runs with these tweaks and when we do, I almost expect to see an 11 second ET.
Check out the video with all of the runs below and congrats to the team behind this build for putting together such a quick car with so little work. Amazing.
