2015 Mustang GT breaks into the 11's in the 1/4 mile!




It went 11.77 seconds to be exact and past the traps at 116 mph and that's with minor modifications. The modifications were courtesy of the folks at Ford Racing. They recently got a hold of three 2015 Mustangs, one with the 2.3L EcoBoost engine making 310 hp and two GT's with the 5.0L V8 making 435 hp.




The power modifications are minor for two of the three Mustangs. The 2.3 EcoBoost gets a "Prototype Off-Road Exhaust" which most likely means there are no catalytic converters or "cats", a more free flowing exhaust and a tune. One of the GT's gets the same off-road exhaust treatment and a tune plus "ARH Cobra Jet Long Tube Headers". In the video, they say they did "a few changes to the air intake system but basically these are close to what any consumer can buy" so they may have included a K&N drop-in filter which FRPP Performance Packs for the 2014 Mustang GT included or an aftermarket CAI with a cone style filter.

The final GT gets the full treatment which includes all the above plus a Ford Racing Roush supercharger and obviously a new intake to accommodate the supercharger. It is unclear what the boost psi level is for the supercharged GT and what the tune raises the EcoBoost psi to but the 1/4 mile numbers are great. Additional suspension parts and drag slicks help the drop the time.

The passenger and rear seats are removed and the driver seat is replaced with a race seat but that seems to be the extent of it for weight savings, probably to substitute for the roll cage and testing equipment if any are fixed to the car. If you pause at 2:18, you'll see one of the the mounting points for the front passenger seat surrounded by black (the carpet). I know the front seats on the S197 Mustangs weigh about 60 lb. each (mine weighed 57 lb. with the frame). According to American Muscle, a rear seat delete kit on the S197 Mustang saves "up to 30 lb."  Between the race seat and removed passenger and rear seats, total savings should be under 120 lb. The roll cage probably offsets most of that if not all so overall difference, positive or negative, compared to a stock interior is probably negligible.

If these parts are available through Ford Racing like power packs for the S197 and maintain warranty if installed by the dealer, it will make a lot of people happy. Watch the video above to see the new Mustangs going at it or scroll below to see a list of modifications and 1/4 mile numbers although no dyno numbers are listed.
