We’ve got some great video footage of a modified 2010 Cadillac CTS-V running heads up against a bone stock 2012 Nissan GT-R. The CTS-V which normally comes with 556 horsepower has been modified with a modified supercharger pulley to up the boost pressure, headers, full exhaust along with some cooling and tuning upgrades. We estimate the CTS-V picked up around 80-100 HP with the modifications. It’s a close race with the stock 2012 530HP GT-R edging out the CTS-V by just a bit with the CTS-V running 11.38 @ 122.71 MPH vs the GT-R running 11.19 @ 124.26 MPH.
