It seems that the question that we get asked the most is "what's the next step?" In the case of our 11.0-second 2018 Mustang GT Premium, our next step was a giant leap, with a Whipple supercharger install and fuel switch to E85! As is the case with most of our projects, we got numbers on 91 octane and E50 also, for those who aren't looking for a fuel system just yet. But for those who are looking for a setup that will simply walk into the 9-second zone at the track, this is the Mustang for you.
“Our 885 rwhp dyno run proved we had the power to move the 4,050-pound Mustang into ludicrous mode, as the supercharger and fuel switch added nearly 400 horsepower!"
The build started with a performance package that's virtually identical to our 10.98 at 126-mph ride that was featured in Muscle Mustangs and Fast Fords. The white car was soon clicking off low 11s at 127 mph, with track conditions being about the only thing keeping us from the 10s. Unlike our red car, we decided to blast right past the 10s and shoot for 9s by installing a Whipple Gen 5 supercharger pullied to 16 psi of boost.
Of course, the supercharger needed supporting mods, which meant triple Walbro 525s, ID 1050 injectors, an oversized heat exchanger, and a massive 132mm throttle body. The car itself was upgraded too, with a torque converter of our own design, GForce aluminum driveshaft and upgraded halfshafts, BMR springs, cradle lockout, and Viking rear shocks. Some weight was also removed with Baer front drag brakes, and Weld wheels, and traction was turned up to 11 with Mickey Thompson drag radials.
After dipping into the deep 10s on pump gas, we were ready for 9s in the quarter on E85. Our 885rwhp dyno run proved we had the power to move the 4,050-pound Mustang into ludicrous mode, as the supercharger and fuel switch added nearly 400 horsepower! After the tire smoke settled the E.T. Boards read 9.64 at 145 mph, with an awesome 1.45-second 60-foot time. 10-seconds naturally aspirated? Check. 9s and 900hp with a blower, yep we got that too. Is anyone ready for 8s? Stay tuned.
