Prior to being a crew chief, Bugarewicz was the engineer for
Kevin Harvick's No. 4 team at SHR, where he won the
2014 championship with him as well as a second-place points finish in
2015, which included a remarkable thirteen second-place race finishes and 28 top-ten race finishes for Harvick and the team that year. He currently serves as director of performance for SHR. In 2016, he was promoted to crew chief for SHR's No. 14 team, where he worked with
Tony Stewart in
2016 and
Clint Bowyer from
2017 to
2019. In 2020, he became the crew chief for SHR's No. 10 Ford Mustang driven by
Aric Almirola for SHR in a swap with
Johnny Klausmeier, who moved from the No. 10 car to the No. 14 car. He was promoted to Performance Director for SHR in 2022. On May 31, 2023, NASCAR issued an L3 penalty to
Chase Briscoe and the No. 14
Stewart–Haas Racing team after a counterfeit part was found on the car after it was taken to the NASCAR R&D Center after the
Coca-Cola 600. Crew chief
Johnny Klausmeier was suspended for the next six races (Gateway, Sonoma, Nashville, the Chicago Street Course, Atlanta and New Hampshire) The team decided not to appeal the penalty and Bugarewicz returned to crew chief for SHR for Briscoe in these six races. ==References==
