2011 5.0L Mustang NA vs. Kenne Bell
Run on the Dynojet, the '11 5.0L automatic produced 361 hp and 349 lb-ft of torque at the wheels. Not only were the power numbers impressive, but unlike the original 5.0L, this DOHC motor revved happily out to 7,000 rpm. Running 9 psi of boost and tuned for 94-octane, the intercooled Kenne Bell supercharger system increased the power output to 564 hp and 482 lb-ft of torque. The tune for 91-octane will be slightly less, as the elevated static compression will not tolerate excessive ignition timing.
