Lingenfelter Performance Engineering is one of the most trusted names in aftermarket performance, and for good reason. Known for their work on modifying General Motors products, the team at Lingenfelter are no strangers when it comes to ridiculously powerful vehicles. In a recent Collaboration with Armageddon Turbo Systems from Albuquerque, New Mexico, the Michigan-based tuning house have made a GMC Sierra 1500 have power figures that dwarf that of the upcoming GMC Hummer EV Pickup.
In order to out gun the 1,000 horsepower battery-powered GMC Hummer, the two teams involved incorporated some of the best parts they have on offer for the pickup’s small block V8. Lingenfelter Forged Rods and Pistons help to toughen up the bottom end, while their CNC ported heads, Hi-output DI fuel system and GT31 Camshaft help to get the motor ready for forced induction. That is where Armageddon Turbo Systems steps in with their own kit, featuring twin Garret GTx3576 Gen 2 Turbos, an air-to-air intercooler and an external cooling reservoir.
Thanks to the video posted by Lingenfelter, we can see and hear just what this GMC Sierra 1500 kit is all about. On the engine dyno, the truck managed to produce 1,170 horsepower and 1,014 foot-pounds of torque at only 13 pounds of boost. That translates to 965 wheel-horsepower, but the torque figure is limited by the transmission to *only* 888 foot-pounds. Perhaps even more impressive, when running on 93 octane pump gas the truck still puts out an incredible 858 WHP and 837 ft-lbs of torque.
Now, we know that the Super Bowl spot for the GMC Hummer stated that it will make 1,000 horsepower and 11,500 ft-lbs of torque. We have already explained why that torque figure might be represented the way that it is, but just know that it all has to do with gear ratios and torque multiplication. With that being said, in reality this GMC Sierra 1500 might just have the upcoming electric truck beat when it comes to all important four-digit figures.
