    ‘14 CTS-V Sportwagon M6. After road test with service agent demonstrating a sound of minor clacking audible at low RPM, the assessment from the tech guy is to replace supercharger and tensioner belt. My question: Does this make sense if the supercharger is not engaged when at low RPM? Any...

    I'm trying to get an idea of how much interest this idea would generate. There are a few bolt-on kits right now that range from 6.5-10k+ which is a lot more than many are willing / able to spend. What if there was a solution for considerably less than that with a significant gain in power, but...

    Well, low and behold. A day after I was bragging about how well the car was running... Driving in stop and go traffic, I hear a click then a progressively loud thud thud. So loud I'm thinking to myself it's a loose rod, maybe a lifter went. Manage to get the car home. Oddly the thump/thud is...

    I did an install over the weekend to a 2008 Escalade. I thought I would play around and customize the Maggie and make it more efficient in cooling. As you can see in the photos below, I fabricated a much larger HEX in place of the factory one. I also installed a 20gpm pump right next to it on...

    So heres the thing I currently have a E350 and was plannin on gettin a CTS-V as well when I got home from deployment but I am really diggin the E63 too.
