As you're well aware, General Motors currently sells truck-based sport utility vehicles under its Cadillac, GMC, and Chevrolet brands. For some reason or another, only the Caddy has been treated to a supercharged performance version. The good folks at Lingenfelter aim to change that with their Magnuson-supplied blower, namely an Eaton TVS 2650 compatible with both the 5.3- and 6.2-liter versions of GM's fifth-generation small block.
Although it normally stickers at $9,150, the supercharger is $1,750 off for a limited time. In addition to said blower, prospective customers also have to spend $2,600 for the ECM calibration. The supercharger, calibration, and installation will set you back $14,750 at the moment of reporting.
Gifted with a charge air intercooler, the Roots-type supercharger uses a Lingenfelter control system. Designed for use with the stock 90-millimeter throttle body, said blower promises 150-plus horsepower and more than 100 pound-feet (136 Nm) of torque at the rear wheels. Lingenfelter quotes 650 hp and 630 lb-ft (854 Nm) for the 6.2 at the crankshaft with 6 psi of boost, whereas the 5.3 is listed with 545 hp and 535 lb-ft (725 Nm).
By comparison, the high-performance small block in the Escalade-V produces 682 horsepower at 6,000 revolutions per minute and 653 pound-feet (885 Nm) at 4,400 revolutions per minute on premium fuel. Otherwise put, you can upgrade your Tahoe, Suburban, Yukon, or Escalade to numbers that would make the Escalade-V blush in awe.
Total price? Let's take the Tahoe Z71 with four-wheel drive and the 6.2-liter engine as our starting point, with said configuration retailing at $76,900 (including the $1,995 destination charge). Add $14,750 on top of that for a grand total of $91,650. Cadillac wants $154,290 for the short-wheelbase V, which comes with full-time active AWD that shifts 70 percent of the torque to the rear at launch.

Compatible with 2019 and newer models, the Lingenfelter Magnuson supercharger kit bears part numbers L250867219 for the 5.3-liter V8 and L250877219 for the punchier mill. The supercharger is covered for three years or 36,000 miles (60,000 kilometers), whichever comes first.
Magnuson's Dynamic Flow Tuning inlet porting method enables the use of GM's throttle body. It should be highlighted that the 5.3-liter L84 and 6.2-liter L87 differ from the previous L83 and L86 in one respect. More specifically, the older V8s feature Active Fuel Management as opposed to Dynamic Fuel Management. AFM turns the V8 into an I4 to save fuel, whereas DFM offers 17 patterns in total.
DFM can shut off seven of the cylinders, which is crazy when you think about it. Dynamic Fuel Management wouldn't be possible without an electromechanical system for controlling the hydraulic valve lifters. According to General Motors, this technology improves fuel economy by 5 percent over the older Active Fuel Management.
Those who want V8 muscle all the time can easily disable Dynamic Fuel Management with a device from Range Technology. Also compatible with AFM-equipped SUVs and trucks, the Range Technology disabler currently retails at $236.95.
After a 1:43 scale model of a Ferrari 250 GTO sparked Mircea's interest for cars when he was a kid, an early internship at Top Gear sealed his career path. He's most interested in muscle cars and American trucks, but he takes a passing interest in quirky kei cars as well. Full profile
