Meet the World's Fastest 2015 Ford Mustang EcoBoost

We have been watching the progress of the 2015 Ford Mustang EcoBoost project car of the Mustang performance experts at American Muscle but today, we bring you a look at an even quicker turbocharged 4-cylinder Mustang – one which is claimed to be the fastest of its type in the world.

Join us...    

While the 2015 Ford Mustang EcoBoost being built by American Muscle is being improved upon while preserving its creature comforts, this turbocharged 4-cylinder 2015 Mustang is owned by someone who is putting fast before everything else. This EcoBoost Mustang is owned by Brad Gusler and with the help of Watson Racing, SCT and Race Star wheels, this fuel efficient package has been converted into a full blown race car. As a result of these changes, this 4-cylinder Mustang is able to blast down the quarter mile in the mid 11 second range with a drivetrain that is largely factory-stock. According to Ford Racing Nation, Gusler’s Mustang is the fastest EcoBoost model in the world in terms of quarter mile capabilities.

Building the World’s Fastest EcoBoost Mustang
It should be noted that the 2015 Ford Mustang EcoBoost in the video below is nothing like the turbo-4 Mustang that we featured recently from American Muscle and Bama Performance. Brad Gusler’s Mustang EcoBoost has been completely stripped of everything that isn’t 100% necessary to get down the quarter mile as quickly as possible. The entire heating/air conditioning system has been removed, as has the sound system, the airbags, the rear seat, the sound insulation and the rest of the nonfunctional interior items. Watson Racing than added a 6-point roll cage, a lightweight tubular k-member, a tubular front bumper system, Strange front and rear suspension, lightweight Aerospace front and rear brakes, 3.73 gears, Ford Racing half shafts, IRS bushings, a Cobra Jet fuel cell and a Cobra Jet intercooler tank.

Next up, a Precision Turbochargers 55mm turbo has been swapped in place of the original with a JPC intake helping to feed this hungry snail while an air to water intercooler helps to get intake air temps down. Everything else in the engine and transmission is factory stock, but with a good tune, this monster turbo setup allowed the EcoBoost Mustang to make 353 rear wheel horsepower.

Finally, a set of Race Star wheels wrapped in skinny tires up front and big sticky tires out back help this EcoBoost Mustang get down the track as quickly and as smoothly as possible.

The World’s Fastest EcoBoost Mustang
Thanks to the massive weight reduction, the chassis and suspension upgrades and the big turbo, this 2015 Ford Mustang EcoBoost blasts down the quarter mile in 11.77 seconds, which Ford Racing Nation claims is the fastest quarter mile time for a new EcoBoost Mustang thus far. Mind you, he hasn’t changed any other components of the engine or the automatic transmission, so there is a ton of potential left in this turbocharged Mustang.

And to think…some of the know-it-all commenters insisted that no one is going to bother to modify the 4-cylinder Mustang. Wrong again, fellas.

All that for an 11.77? While a full bolt on gts are running that and under with full weight... Ford really missed the mark on this 4 banger.... under powered from factory. All while the new focus rs will be AWD with the same mill producing more power with less weight. I'm a 2014 gt owner but still Ford.... really?

Missed the mark? Should they have made a competitor to the GT? Should they compete against themselves? What they did is give you the option to save $5K and run quick stoplight to stoplight times competitive with more powerful options.
What mark did they miss? How is 310hp underpowered?

That's not a lot of hp per weight. Sorry you don't feel the same way. 2.7 nano would have been prefect in this shell. But if you think a stripped out car with bigger intercooler and everything running high 11s is fast then sorry you've never been in a pure bolt on 5.0. 11.77 isn't fast at all. 2014 v6 bolt ons with suspension and dr were running better then 11.77. Look at the new focus rs coming out. Same mill but all vital parts have been upgraded. 2.3 in the mustang is a missed mark. People getting them now will be pissed once focus rs comes here and then that mills upgrades will be given to the 2.3. The v6 right now is still better than the 2.3. Running better times stock for stock. Missed mark

I think the point he was trying to make is of course the GT is faster, why would they produce a cheaper mustang that could go faster than the GT, they'd be shooting themselves in the foot, but this car has a lot more potential than a V6. The glory of this version is that it isn't the GT, it's something else, it is an affordable turbocharged coupe that is a blast to drive and has a lot of build potential.

I own 2015 Ecoboost and am putting more power down than the GT. Also, you are wrong that the 2.3 in the Focus has upgraded parts. It is exactly the same except leading people to believe it has upgraded insides sells parts. The mark is spot on because they wanted it to be a customizable car and that is exactly what it is. One more thing I am not only more powerful than the GT I am getting 25 MPG even with hard driving! Stick with what you know which is only your opinion that really doesn't mean much because it just shows how much you do not know.

Put the boxing gloves away kids. The GT and Eco boost cars each have their place. Chester, you've obviously never been in a 635 rwhp supercharged 5.8 liter Mustang - 11.70s are real slow - if you want to compare.
The engine in the Eco boost car is 140 cubic inches and intented for good fuel mileage and respectable performance - taking weight out of an economy car and getting musclecar performance with a near stock drivetrain IS RESPECTABLE.
The 5.0 Liter Coyote was designed as a high output engine from the start with fuel economy a secondary consideration. The Coyote makes good power, too bad the Mustang GT weighs almost as much as my older F150. Still, with easy bolt on mod's the car is quick, AS IT SHOULD BE.
The "american" car makers are still struggling with what is considered modern engine technology - they'll get a handle on it I'm sure. If they'd get serious about vehicle weight reduction, then the fuel economy/acceleration numbers would really shine.
Modern passenger car engines are revisited WWII piston aircraft engine technology. Yup - 1940s stuff, the only new twists are variable cam timing and electronic engine management. Overhead cams, 4 valves per cylinder, charge cooling etc. 70 year old stuff.

Wish it was that fast in "street trim" than I would be a lil more interested.. Gts are getting pricy, but they seem to be worth it.

Andrew (not verified)    March 31, 2015 - 3:14PM

Its fun to see what they are capable of. And no matter what they made there will always be haters.
How many people that say the GT is in every way better have the means to drop 40-50K on one right now?
The EB gets easily 25+ mpg around town. But if you can drop 50k on a GT you probably aren't worried about gas prices.

Any street car that can pull sub 14 sec in the quarter from the factory is respectable. Especially one that starts in the mid $20k's. Drop under $500 into a tune and it'll break into the 12's with good tires.

Money for speed can't be the only deciding factor either in what is "best". You can build a 10 second 1970-something Malibu for less than 15% of what the GT cost before the mods it took to get to 10.

Money no object? Get a separate car for commuting, going to Home Depot, autocross, trackdays, drag racing, cruising, road trips, etc, etc..
Aside from the Home Depot thing, i think for the money the ecoboost satisfies most of those checkboxes.

Bring him out to albuquerque. I would be glad to out run him at the local track. I just finished my bolt on upgrades and had Motiva Performance here in albuquerque tune my ecostang to 363 rwhp and 402 ft/lbs torque. There is even more potential there, and i still have all of my factory luxuries, a/c, cruise control, bluetooth LOL. Turbo upgrade will come soon for me, but not before i replace pistons and rods, and ARP has a stud kit available. The factory fuel system will be the limiting factory, which should be reliable up to about 600 crank horse.

The Eco boost fills a niche, if Ford missed the mark why is Chevy building a turbo Camaro? It is more of a road course car anyway, it's not really meant for drag strip duty. As far as weight, the government, make the car companies put in all this safety stuff, air bags, door bars ect . Also customers want a quiet ride, with leather, and gadgets which adds up to more weight. Look at the Z28, lighter glass one option, that's a purpose built card. Road coarse is this cars specialty.
So losing more weight is probably not going to happen. Unless of course carbon fiber and light weight metals are used, but then the cost to build the cars would be sky high. the previous generation GT 500 was a beast, but push it hard on the road coarse however, and the car will try to kill you in a few short laps. The Eco boost may be that middle ground, and besides if the Focus RS comes with 345 hp then maybe the blue oval boys will turn up,the wick on the mustang turbo four.

I'm always impressed with an 11.77 at the strip. But to yank everything out of the interior to that extreme, is a joke. I've got a z06 garage queen now and have had single turbo Supras with nitrous, so I've had some nice performance cars over the years and basically lived at the dragstrip from being there everyday it was open. But Livernois Motorsports ran an 11.81 I believe with their stang EB and that was with some Bolton's, tune, and removed the front seat. They didn't take out all that stuff. They even swapped for a bigger turbo. This car looks like a grade a disappointment to me.
And BTW, I picked up a manual Stang EB premium the other day for my daily driver. The premiums are NICE. And fun as HELL to drive. Its got 3.31s in the rear end. Hell, just putting 3.73s, tires, and a tune would really wake this car up. Yet alone the other Bolton's like DP, CAI, short throw shifter, and a better intercooler. I gotta find a new daily driver and Frankenstein this
