From Street Mod to Unlimited, drivers relying on Garrett G-Series turbochargers demonstrated the speed, consistency, and reliability needed to perform at one of the most demanding circuits in the country.

Road Atlanta’s combination of elevation changes, high-speed sections, heavy braking zones, and long full-throttle straights creates a true proving ground for both drivers and equipment. Throughout the weekend, Garrett-powered competitors delivered impressive results across multiple classes.

Dewey DeWitt Resets the Street Mod Record

One of the standout performances of the weekend came from Dewey DeWitt, who captured 1st Place in Street Mod while setting a new class record with an impressive 1:26.515 lap time.
