The runner-up in Sunday's ASA STARS Tour race at the Milwaukee Mile has been disqualified

Ty Majeski was stripped of his runner-up finish in the Father’s Day 100 at the Milwaukee Mile when testing showed the engine from his car to be out of specification, ASA STARS National Tour officials announced Thursday.

The Seymour native finished second to Dawson Sutton after dominating much of the race Sunday. Afterward, the engines from the top two cars were confiscated by the series for testing by an unassociated engine builder in Tennessee.

Sutton's engine passed, but the engine in Majeski's No. 91 Gearheadz Motorsports car "did not pass the baseline testing, failing to meet the parameters as outlined by sealed engine technical specifications, and approved S.E.A.L. guidelines, specifically related to maximum allowable compression ratio," ASA STARS said in a statement.

In a statement, Majeski and the team said the engine was rebuilt by McGunegill Engine Performance after the car last ran in December at the Snowball Derby in Pensacola, Florida, and that the manufacturer accepted responsibility for a "miscalculation during the rebuild process."

The engine and the car raced Sunday were not the same as those with which Majeski won two nights earlier at Madison International Speedway. That car passed initial testing at the track.

The engines from the cars Majeski and Sutton raced Sunday did not undergo that same sort of field testing as they instead were being taken for complete inspection offsite.

The disqualification is the first penalty for technical infraction for the STARS National Tour since the second race of 2023, when an infraction related to the carburetor on apparent winner Dan Fredrickson’s car, found at the track, led to Majeski’s elevation to first place. Majeski went on to win the championship in the series’ inaugural season.
