ART Turbos was born from a lifelong love of engines and wanting to do personal, honest service. Founder Mac Flynn grew up tearing apart motors in the family garage, went on to study automotive repair, and spent over a decade in product management working at leading distributors, directly managing top turbocharger manufacturers like Garrett, Holset, and BorgWarner. He passion is to continue perfecting the craft inside and out — but he wanted to get back to his roots of turbos and working with his hands

So he did. Mac opened ART Turbos in Cottage Grove, Wisconsin with a simple belief: every turbo deserves expert hands and every customer deserves straight answers. As an owner-operated shop, we give each unit our personal attention — whether it's a precision rebuild, VSR balancing, or actuator calibration. No assembly lines. No shortcuts. Just two decades of expertise and a genuine commitment to doing it right.
