When GM unveiled its 6.2L V-8 for fullsize trucks and SUVs in 2008, it sent a shockwave to its competitors and set the horsepower bar to an all-time high. Available in the GMC Yukon Denali, the LS-based engine produced 380 hp and 417 lb-ft of torque. For most people, that much power would make for miles of smiles, but for us gearheads, more power is always needed. Jerry Magnuson and his team at Magnuson Products in Ventura, California, have been producing roots-style superchargers for cars and trucks for some 40 years. The Magna Charger Radix Max intercooled supercharger systems are known for their incredible neck-snapping, low-end torque and overall horsepower gains with immediate boost response. This Magna Charger Radix Max supercharger is offered in three finishes: gray, black, and polished with a 3-year/36,000-mile warranty.

The Magnuson Magna Charger MP1900 has four-lobe rotors with a 160-degree twist that allows for less frictional drag, requiring less power to drive the system. The intercooler system creates cooler discharge temperatures for increased power and on a small-block V-8, the MP1900 can deliver up to an additional 130 hp to the wheels. The Magna Charger MP1900 kit includes a MagnaVolt ignition boost box, an intercooler system with heat exchanger, circulation pump, intercooler reservoir, heat exchanger, hoses, and hardware.
The team at PPC Customs in Clovis, California, headed up by owner Richard Ruiz, assisted installer ace Shane McMullen as they bolted on a Magnuson Magna Charger MP1900 to a '08 GMC Denali 6.2L powerplant. Imagine over 550 hp at the crank and you'll get a good idea of how quick this AWD Denali became in less than one day's work.
From The Driver Seat
The Magnuson Magna Charger Radix Max supercharger and intercooler install was flawless. After the installation the Denali was taken for a fast test drive. The instant torque plants you right back into your seat the power comes on strong and continues to pull all the way through the power curve keeping you pinned in the seat. The instant acceleration and continued power was incredible. The Magna Charger was also very tame while in normal driving mode around town.
