Busch won his first race in over 20 years in a Legends car at Charlotte Motor Speedway last month and has since gone on to take five wins in the Cook Out Summer Shootout series in the Masters category.
His latest triumph came on Tuesday night, with the two-time Cup Series champion going from seventh to first to take the win.
On social media post-race, Busch wrote: "W in the Chat. Went 7th to 1st for our 5th SSO win of the year. Thx for the boys for all their hard work."
Busch is certainly enjoying his time racing in Legends cars once again, giving an interview following his first win last month, in which he could not keep the smile from his face.
At the time, the two-time Cup Series champion told FloRacing: "Not bad. I didn't think we were gonna be that good, but hey, here we are. So feels good."
"Those guys are fast. I mean, they put up some good laps in qualifying, and we were third, but I pulled that one out of my butt ... certainly was just fun to be able to get up front and lead some laps."
Asked how long it had been since he last won a Legends race, Busch replied: "19...maybe 2001 might have been my last win,"
"It's changed a little bit, that's for sure, and so coming out here, racing in the Masters class, I mean, I'm old, I might be the youngest master, but hey, I'm eligible, so might as well go do it."
Busch will be hoping that his success in Legends cars can somehow rub off on his fortunes in the Cup Series as he chases a 2025 playoff spot.
Of course, a win would see him locked in, whilst at the same time, any new winners in the Cup Series over the next six events would see the four spots up for grabs via the points reduce further.
It's certainly set to be a tense but exciting few weeks for the two-time champion and his fans.
