Lingenfelter has released a new supercharger pulley Cadillac's LSA-powered M5-eater, the CTS-V. The 6.2 liter V8 is now force-fed around 12 or 13 psi of boost, upping the Caddy's power and torque past the 600 mark to 630 horsepower (+74 over stock) and 630 lb-ft of torque (+79).
Company main man Ken Lingenenfelter says, "Our new supercharger pulley upgrade kit produces excellent horsepower and torque improvements, while maintaining a safe level of boost and supercharger RPM."
