The Breathless supercharger pulley upgrade kit is designed to enhance the new LSA Cadillac CTS-V supercharged engine. This upgrade kit produces excellent horsepower and torque improvements over the factory 556 horsepower and 551 lbs ft of torque while maintaining a safe level of boost and supercharger RPM. Testing at Lingenfelter has shown 630 BHP and 630 lbs ft of torque with the Lingenfelter pulley upgrade kit installed.
This upgrade kit allows you to send in your supercharger air intake snout and ECM. BPP will provide ECM programming, supercharger snout porting & polishing to improve air flow. BPP also will remove the stock pulley, press the new pulley back on and drill and pin the shaft. The CTSV pulley kit raises boost on a stock engine 3-4 psi.
