[3][4][5] For 2021, Top Gun participated in a test at World Wide Technology Raceway in May, with Enerson driving the #75 Dallara-Chevrolet, which had a throwback livery to the Johnny Lightning-sponsored cars that Al Unser and Vel’s Parnelli Jones Racing used to win the Indianapolis 500 in 1970.

[8] On the first qualifying day, Enerson posted a four lap average speed of 227.283 miles per hour, which was not fast enough to make the top 30 and guarantee a starting position.

[12] Additionally, they sought out applications for small sponsors on the car, which would go on brick decals (like the ones on the start/finish line at Indianapolis).

[13] In the race itself, Enerson retired due to a throttle sensor issue after 12 laps, causing him to finish in last place.

[13] The team reneged on its agreement with the Enerson's to return the two chassis' and other equipment at the end of the season and legal proceedings were required to establish the ownership of the cars.
