Chevy Silverado Gets Raptor-Destroying Firepower With New Supercharger

Tuning / Comments

Conquer everything.

Up to this point, there's been a dearth of options when it comes to supercharger kits for GM's 2019+ full-size trucks, the Chevrolet Silverado 1500 and GMC Sierra 1500. ProCharger may just have been the first to market, announcing in February that it had developed new bolt-on kits based on their own centrifugal supercharger design, but there hadn't been much talk of any positive-displacement supercharger solutions.

But at long last, Whipple has just announced new twin-screw supercharger kits for the Silverado and Sierra V8 models, based around a gargantuan 3.0-liter blower that looks big enough to pressurize a small house, available in several different finishes.


Tuning has always been the obstacle with supercharging the latest GM cars and trucks. From 2019, the light-duty Chevrolet Silverado and GMC Sierra switched to a new, tough-to-hack electrical architecture that made recalibrating the Powertrain Control Module (PCM) seem all but impossible.

Whipple has gotten around that, it seems, by partnering with HPTuners for the PCM tuning, leaving the company to focus wholly on developing the blower.

Whipple's new 3.0L unit is based on its latest fifth-generation twin-screw supercharger technology, capable of reaching over 100% volumetric efficiency. It has a big dual-pass heat exchanger for cooling the intake charge, and included with the kit are a high-flow aluminum intake manifold, an adjustable idler system with a billet idler plate, and an upgraded spring-loaded tensioner.

Just about the only thing we don't know about the new Whipple twin-screw supercharger kit is what sort of power gains can be expected, but we imagine that data will be available soon enough.

Pricing stands at $6,750 to start, regardless of which V8 the blower is going on, with special finishes costing $600 to $800 extra.

That's a lot of coin, but when you figure that Whipple is the first to market with a complete twin-screw supercharger solution for the 2019+ Chevrolet Silverado and GMC Sierra, and that at 3.0 liters, their unit is a full 600cc larger than Dodge's SRT Hellcat blower, that price becomes easy to justify.
