What began as an owner’s passion for learning the fundamentals quickly turned into a serious pursuit as Mulcahy transitioned into club racing, where he built a strong foundation in racecraft and competition.
His rapid growth and commitment to improvement opened the door to Porsche Sprint Challenge USA West by Yokohama, where he tested himself against seasoned drivers and proved he belonged at a higher level.
Now a full-season competitor in Porsche Carrera Cup North America for the first time this season, Mulcahy stands as a shining example of how Porsche’s ladder system can transform an everyday enthusiast into a legitimate contender at the top of one-make racing.
“The Porsche Experience Center Los Angeles was where it all really started for me,” Mulcahy said.
“When I bought my Porsche 911 GT3 RS, I knew I couldn’t just drive it on the street and not experience what it was really built to do.
“I had buddies doing track days, and I always said I wanted to join them, but I was busy. I was building my business, raising a family. Life was hectic.
“One day, after driving past the Porsche Experience Center in LA about a hundred times, I finally looked into it. I found out they had an “Owner’s Day” where you could bring your own car out to the track.
“They had coaching, they had a structured program. I signed up immediately. I didn’t hesitate. I committed to three sessions right away, just to get my feet wet.
“And after that first session, I was absolutely hooked. There was no turning back. That first time on track changed everything for me.
“It’s a fantastic entry point into motorsports. It gives Porsche owners — and newcomers too — a safe, structured environment to learn about car control, handling, and driving dynamics.
“It’s the perfect first step before you go jump into club racing or competitive events. I don’t think I would have gotten serious about racing without starting there.
“It gave me the foundation, the confidence, and the passion to go further.”
After building his confidence at the Porsche Experience Center, Mulcahy took the next step by entering club racing events with the Porsche Owners Club and Porsche Club of America, where he began applying his skills in a competitive environment.
“The club days were great environments to learn in. It was competitive, but not overwhelming,” Mulcahy said.
“It gave me a chance to start applying what I was learning, building up my skills in a real track environment. But pretty quickly, I realized that taking my GT3 RS to these events wasn’t the best idea. It’s an incredible car, but it’s expensive, and the risk of damaging it was always at the back of my mind.
“So I decided to go get a proper race car. I bought a 991.2 Cup car and also a Spec Boxster so I could really cut my teeth — learn the right way without constantly worrying about the car.”
After gaining experience in club racing, Mulcahy earned his provisional license and took a significant step forward by joining GMG Racing, where he began training in a complete driver development program.
“I signed up for the POC Racers Clinic to get my provisional racing license. That was a real wake-up call. Dwayne, who ran the clinic, was tough. He was strict, he didn’t sugarcoat anything,” Mulcahy said.
“But it was precisely what I needed. It forced me to focus, take everything seriously, and understand what it meant to drive at a high level – to be consistent and race responsibly.
“Going through that program gave me a lot of respect for the craft of racing, and once I earned my provisional license, I knew that I didn’t want to just stay at the club level. I tried to keep pushing and see how far I could go.
“I reached out to GMG Racing. They were the team I always admired from a distance — super professional and had a strong reputation. They invited me to come out and do a test day at The Thermal Club.
“So I brought my Cup car out there, worked with Andrew Chinnici who had coached me a PECLA, and just tried to show what I could do. It wasn’t anything official at that point — just a test to see if it was a good fit. After that day, they offered me a spot in their driver development program, which was huge for me.

“I spent that entire summer pounding out laps at Thermal. It was brutally hot — I mean, 115 degrees some days — but I was out there. There were days when I was the only car on track, just session after session, lap after lap. It was mentally and physically tough, but it was the best thing for my growth. I look back on that summer as the foundation for everything that’s come since.”
Mulcahy ran his first race with GMG Racing in October 2023 at The Thermal Club, marking an important milestone as his training transitioned into real competition.
After that debut, it quickly became clear that if he wanted to stay competitive beyond club racing, he would need to move up to the latest equipment. Committing fully to the next step, Mulcahy upgraded from the 991.2 Cup car to the newer 992-generation Cup car.
“I entered Porsche Sprint Challenge USA West with the 992 Cup car, starting with the season opener at Spring Mountain in March 2024,” he said.
“Spring Mountain was tough. It was a wet weekend, conditions were tricky, and I made a couple of mistakes. I spun twice during the races — just pushing a little too hard, trying to find the limit. But in Race 2, I pulled it together, kept it clean, and ended up earning the Hard Charger award for passing the most cars.
“That felt good because it showed that even when things go wrong early, you can regroup and still have a good result.
After that, we went to Utah Motorsports Campus. Unfortunately, that weekend ended badly. I was pushing hard, caught a curb wrong as I came out of a corner, and ended up rolling the car. It was a big crash. Thankfully, I walked away okay, but the car was pretty torn up.
“When I came back for Laguna Seca, it felt like things started clicking again. I had a new perspective after the crash — I was more focused, more patient.”
But it was Road America and Sonoma where things really turned a corner, and Mulcahy started fighting for podiums.
After finishing the Sprint Challenge USA West season, he had to make a decision. He could go back and fight for a championship in Sprint Challenge, or I could step up to Porsche Carrera Cup North America.
“It was a tough call because Sprint Challenge would’ve been the “safe” option — I had experience there now, I knew the tracks, and I would have had a real shot at winning the title,” Mulcahy said.
“Carrera Cup is a whole different level — bigger fields, higher pressure, tougher competition. But that’s exactly what I wanted.
“Sebring was my first Carrera Cup weekend. That event was massive. Huge fields, high intensity from the first session on. It felt like everything was cranked up — the talent level, the pressure, the expectations.”
The Californian came away from Sebring with fourth and fifth place finishes in the Pro-Am class in his debut at Sebring. After also driving a Porsche 911 GT3 R in GT America at Long Beach, Mulcahy now heads to the Formula 1 Miami Grand Prix for round two of the Porsche Carrera Cup North America championship.
“Through this whole journey, the mindset I’ve taken is all about the Japanese philosophy of Kaizen — small, consistent improvements every day,” he said.
“I’m proud of the progress we’ve made so far — from Owner’s Days at PEC LA, to Sprint Challenge USA West, and now into Carrera Cup. But at the same time, I know this is just the beginning.
“I’m still learning. Still growing. Every session, every race, every mistake — it’s all part of the process
