A supercharger and intercooler should do the trick, and it comes with a warranty.
The wild-looking new Chevrolet Blazer returned to the streets in 2019 featuring either a four- or six-cylinder engine making a max of 308 hp and 270 lb-ft of torque. That was before Lingenfelter Performance Engineering got its hands on it. The GM go-fast tuner has a supercharger package for the SUV that will increase power by about 100 hp at the wheels; it should be about 450 hp at the crankshaft.
The kit starts with an Edelbrock TVS1740 supercharger with a high-efficiency intercooler and a powder coat finish. Surprisingly, it will be legal in all 50 states and includes professional installation, testing and calibration. It also comes with a warranty on the assembly and a certificate of authenticity.
Lingenfelter, for the uninitiated, is an engineering company that pushes Chevy Corvette C8s, Cadillacs (and Pontiacs!) into the stratosphere with engine, electrical, intake and fuel system upgrades. For instance, it took the last Chevrolet Camaro ZL1 and boosted it to 800 hp with a boatload of under-the-hood upgrades. That package is just a touch over $20,000, but the outfit does less expensive upgrades too.
This package for the Blazer is a similar kit to the one it offers for the Chevy Colorado and GMC Canyon, though the engine in those pickups is placed longitudinally, as opposed to the transverse placement in the SUV.
As you can see, there aren't a lot of visual cues to tell you that this is something special. There are a few "S" badges and a few Lingenfelter badges, which, one could conceivably remove to make this a real sleeper SUV. Not that you see a lot of Blazers looking to race at stoplights, but if you did…
The packages on the Colorado and Canyon cost about $7,000. There's also a stage 2 package that includes a performance intake and exhaust. We're still waiting on the price of this specific package for the Blazer, but we expect it to be close to those others. We'll update when we find out more.
