That's a mighty big number, associated only with Richard Petty's unreachable record of 200 Cup Series wins. It was once thought Jeff Gordon might challenge the mark, but he fell off the pace long ago and currently has 82.
But if Busch is flexible with the goal he revealed before this season, he's got a shot at reaching Petty's mark.
With an asterisk, that is.
Busch's win Saturday night at Richmond International Raceway was the 50th of his career spanning NASCAR's top three series. It came on his 24th birthday, and Busch believes he could reach 200 wins if he maintains his desire to race in every event possible.
"But I know the older I get I'll start slowing down some way," he said. "Hopefully I can achieve that goal. It would sure be nice to get that. I know it's not 200 Cup victories like Richard Petty has, but it will still be a phenomenal mark for me."
It's a mark few thought he could reach just two years ago. His talent level has never been questioned, but there's a reason Busch has been called "Wild Thing."
He was ready for NASCAR when he was just 16, but an age minimum sent him back to the sidelines for a two-year wait. Once admitted to the big leagues, he came in full of unbridled desire, fearlessness and a lack of maturity.
Busch pushed his cars beyond the limit, taking risks that often ended in a wad of crumpled sheet metal. He pouted when he didn't win and threw temper tantrums when things went against him. Team owner Rick Hendrick tried to tame him, but he finally cut Busch loose at the end of the 2007 season to make room for Dale Earnhardt Jr.
Joe Gibbs Racing snapped him up, and Busch has steamrolled his way through NASCAR since. He won 21 races last season spanning the Sprint Cup, Nationwide and Truck series.
His pace has slowed a bit this season -- partly because of a monthlong slump he brought into Richmond -- but he's struggling only by his own lofty standards. He now has eight wins on the year: a series-leading three in both Cup and Nationwide, and a series-leading two in the trucks.
"He's pretty good," said Jeff Burton, who finished third Saturday night. "You are what your record says you are. I just saw that stat 'most wins before the age of 25,' and that's pretty impressive. Everything he sits in, he goes fast in. That's a sign of a really good race car driver."
