Connor Mosack showed speed throughout the inaugural The Loop 121 NASCAR Xfinity Series race at the 2.2-mile, 12-turn Chicago Street Course, qualifying a career-best fourth and running among the top-five for the majority of the race. An issue with the carburetor on his No. 19 Porter Pipe & Supply Toyota GR Supra, however, derailed Mosack’s strong run. The problem first developed on lap 21 when Mosack felt a loss of power, specifically in third and fourth gear. When the caution came out for a nearby lightning strike on lap 25, Mosack ducked into the pits for his crew to lift the hood and diagnose the problem. He returned to the track in 35th and shortly thereafter, the race was postponed for rain. But with a plan to replace the carburetor on the Porter Pipe & Supply Toyota and seemingly plenty of laps still remaining, Mosack eyed opportunity to work his way back toward the front when racing resumed. It never happened. Persistent rain forced NASCAR to call the race official after 25 laps, denying Mosack a chance to return to the top-five and saddling him with a 35th-place finish.
Connor Mosack driver of the No. 19 Porter Pipe & Supply Toyota GR Supra for Joe Gibbs Racing:
“I feel like we were a solid, top-five car. Even kind of riding around a little bit, I feel like we had some pace in the bank all weekend that we were saving for when we needed it. So we took it pretty easy in practice, and then used a little bit of it for qualifying – left a little bit out there, for sure, but we were pretty happy with where we started. The goal was to always stay in the top-five, at least for the first half or three-quarters of the race and just keep the thing in one piece and be there at the end. That was our goal, but we didn’t get that opportunity. We had a carburetor issue about lap 21 or 22 and started falling back quickly. Thankfully, we got a caution. We came down pit road to take a look at it and, obviously, we went to the back of the field before they called it yesterday for lightning. The plan for today was to get the carburetor changed and then we’d have 30 laps to make our way back to the front. But with them calling the race, we didn’t get that opportunity and it was really disappointing. I especially hate it for our partner, Porter Pipe & Supply. They brought a lot of people here and they were really excited to see the race and see the car. We know we’ve got the pace. There are things from the first half of the race that we certainly can learn from and apply to Road America. So it wasn’t a complete waste of a weekend, by any means, but we would’ve liked to have had a better result.”
