Fastlane Turbo ZR-1 upgraded CTS-V
We all know that one of the major differences between the LSA in the CTS-V and the LS9 in the ZR-1 is the larger capacity blower bolted to the mega-Vette. What would happen if you reverse engineered the ZR-1's blower onto the CTS-V's engine? How about an additional 130hp. Fastlaneturbo.com did exactly this and you can watch their dyno run below. Enjoy.
