Show original supplier description
The ProCharger Stage II Intercooled Tuner Kit is a high-performance forced induction system designed specifically for the 2016-2019 Cadillac CTS-V with the LT4 engine. Unlike standard HO systems that share a 6-rib belt drive, this Stage II kit utilizes a dedicated 8-rib belt drive system off the crankshaft to ensure stable power delivery and reduce belt slip. The system includes a D-1SC head unit as standard, though it is engineered to support higher-capacity blowers like the F-1R for those seeking maximum output. This tuner kit is a comprehensive, precision-matched package built for consistent, repeatable performance. The dedicated drive design provides the robust foundation necessary to support significant increases in horsepower. Please note that as a tuner kit, this system does not include engine management calibration, and professional installation is recommended to ensure correct fitment and integration with existing engine components. Available configuration options include various head unit upgrades, finish choices for the housing and brackets, and additional hardware such as an air-to-air race intercooler or an ATI performance balancer upgrade.
