We showed you the details of Reed Fullmer's '07 GMC Sierra, and we're sure you agree it's a nice truck. If you were wondering how they made more than 375 hp to the rear wheels and still received 15 mpg, we'll show you in this story.
MagnaCharger has long been known for making serious but safe horsepower, and when it came time to bolt-on some ponies to the Fullmer's daily-driven show truck, the choice was obvious. Just released for shipping when we arrived to install the blower, the new '07 Chevy and GMC supercharger system comes as an entire intake manifold with a Radix intercooled supercharger bolted onto it, complete with internal bypass valve, fuel injectors, and aluminum fuel rails. Also included in the kit is the MagnaVolt fuel pump booster, large front-mount water heat exchanger, air inlet tube, and all of the hardware in individually-wrapped bags. As an added bonus, MagnaCharger offers a three-year or 36,000 mile powertrain warranty for peace of mind.
When it came time to order one of these brand-new kits, we called Stylin' Trucks. As an authorized distributor of MagnaCharger, Stylin' has plenty of kits in stock and we had a kit shipped to us in no time. This supercharger system takes no prisoners and can be installed in less than a day. For our evaluation of the product, check out the From the Driver Seat section.
 Our test '07 GMC Sierra was decked out in painted plastics and a custom CGS intake, but the power attained from the intake couldn't compete with the added power of a MagnaCharger, so we decided out with the red and in with the ponies. |  Out of the box and onto the shop table, the polished Radix supercharger and manifold looked pretty glorious as it was awaiting the factory throttle-body and vapor canister. The MagnaCharger kit also included the intake gaskets, heat exchanger, high-flow filter, MagnaVolt, and tuning hardware. |  After removing the intake cover, intake tube, and disconnecting the battery cables, head installer Simon disconnected the PCV hose from the intake, fuel line clip, all eight fuel injector harnesses, MAP sensor harness, and throttle-body harness. He then loosened and removed the alternator and each intake manifold bolt with a ratchet. |
