Q is for QuickerIf for some reason 350 hp doesn't trip your trigger, Steeda can up the underhood ante with a pair of supercharged Q packages. The Q400 adds a Steeda/Magna Charger Roots-style supercharger system to the stock-displacement 4.6L engine to pump the output to 460 hp and 450 lb-ft of torque. The Q525 (above) takes performance up another notch with a stroked and supercharged 5.0L for more than 500 hp and 530 lb-ft of torque. The top Q also gets more standard equipment, such as big brakes and a full complement of suspension mods. During a Steeda media day, we witnessed a Q525, piloted by our editorial cohort Evan Smith from Muscle Mustangs & Fast Fords. It ran an 11.70 at 120 mph in the quarter-mile.
