Looking for more power and torque for towing, we knew that this 2014 5.3L Silverado would benefit most from a roots-type supercharger like a Magnacharger. Wanting to retain stock driveability with better power, we decided on Magnacharger’s 2014 Silverado Kit, along with a set of Kooks 1 7/8″ headers to let it breathe properly. We baselined the truck on the dyno at 288 rwhp & 313 ft/lbs tq.
Magnacharger’s new kit makes for a nice install, and looks right at home on the new Gen V engine. The Kooks headers also fit very well, and will last for many years to come. We went down a couple of pulley sizes to recoup the boost that would have been otherwise lost with the headers.
Going back to the dyno after the install, we picked up 132 rwhp & 125 ft/lbs tq! Final numbers were 420 rwhp & 432 ft/lbs tq. The truck remained very quiet and kept stock driveability as well…until you touch the gas pedal and it starts accelerating! This package will make a large difference in every day driving and especially towing as well.
