Those looking to increase the power of their 2014-2016 Chevrolet Silverado/GMC Sierra pickup truck, courtesy of a roots-style supercharger, are in luck. Street Legal Performance (SLP) has just announced the SLP Supercharger System, which utilizes Eaton’s 1900 TVS supercharger for trucks equipped with GM’s 5.3-liter Ecotec3 L83 or 6.2-liter Ecotec3 L86 V8 engines.
Owners of the Silverado/Sierra with the 6.2-liter L86 V8 will see gains of 170 horsepower at 5,700 rpm and 130 pound-feet of torque at 4,100 rpm, which is 41 percent more horsepower and 28 percent more torque than factory specs, translating to 590 horsepower and 590 pound-feet of torque.
Trucks with the 5.3-liter L83 V8 will gain 165 ponies at 6,000 rpm and 167 pound-feet of twist at 3,200 rpm — a 46 percent increase in horsepower and a 44 percent increase in torque, translating to a total of 520 horsepower and 550 pound-feet of torque. Pretty potent, wouldn’t you say?
|Engine:||5.3L L83 V-8||6.2L L86 V-8|
|SLP supercharged horsepower:||520||590|
|SLP supercharged torque:||550||590|
Sure, one could probably make more power with a (more complex) turbocharger system, but the benefit of using a supercharger is having power on tap throughout the entire rpm range and not having to worry about turbo-lag. Not to mention the fact that these supercharger kits feature similar technology to that of the Cadillac CTS-V, Chevrolet Camaro ZL1, and Corvette Z06.
These roots-style superchargers feature twin four-lobe rotors twisted 160-degrees. SLP states that the benefits of such a design include “vastly cooler discharge temps than competitive twin screw designs, higher volumetric capacity, higher operating speeds, a smoother, more efficient flow of air into the engine, and improved noise and vibration characteristics.”
