EFI Renegade For EFI Renegade racer Chad Allmandinger, racing is a family affair. Chad's brother and father were on hand at Bradenton to help Chad focus on racing. You shouldn't miss Chad's ride at all since it's a ‘80 Mercury Capri, and well, it's not exactly subdued. Chad's been racing EFI Renegade for a while now, but with the new season he was able to get his first win, and run his best ever time in the process. With a BES Race Engines-built 310ci bullet under the hood, Chad relies on 30 pounds of boost from a Vortech YSi-Trim supercharger. Though he's made a few final rounds in his NMRA career, Chad wasn't able to taste victory.
