+185 PS: General Motors SUVs and trucks get aftermarket supercharger option

General Motors doesn’t cut too many corners equipping its utility vehicles with powerful V8 engines, but GM specialist and tuner Callaway still offers a considerable boost over stock performance.

Two packages are available for ordering, called the SC502 and SC602. The former targets the 5.3-liter V8, pushing it to 527 PS (520 hp / 388 kW). The latter is meant for the larger 6.2-liter mill and persuades it to churn out 610 PS (602 hp / 449 kW) – whole 185 metric horses (182 hp / 135 kW) more than the stock output. It is also worth pointing out that both tuning kits are road-legal and emission-compliant throughout the entire United States.

From the technical perspective, the upgrade consists of an Eaton TVS supercharger encased in a custom housing, a TripleCooling system for keeping the induction air nice and cool, and a stainless-steel exhaust system culminating in a quarter of tailpipes. The latter is said to improve the engine’s working temperatures while simultaneously endowing it with a richer sound and even raising its performance a little bit.

The kits are compatible with all recent Chevrolet Tahoe and Suburban, GMC Yukon and Cadillac Escalade modifications, including top specs like the XL and the ESV. A number of trucks and SUVs is slated to join the supported list soon.

As one would expect, though, such extensive mods come at a price to match them, and this one is no exception. The bare minimum you’ll be expected to pay is $25,000.
