SKUSA To Allow KZ Engines To Run Alongside The 175SSE In Shifter Classes At The 2020 SKUSA ProTour And ProKart Challenge
Wednesday, 12 February 2020 11:05

With the 2020 incarnations of the SKUSA ProTour and ProKart Challenge just weeks away, Superkarts! USA is excited to confirm the expansion of their shifter kart classes to now include the popular KZ engine format. The move comes after careful deliberation between both factions of IAME USA, and valuable input from teams throughout the SKUSA paddock.

“We feel we have a shifter kart engine that’s second to none,” explained SKUSA’s principal Tom Kutscher. “That said, we would be lying if we said it’s been a perfect rollout. Various issues hindered the format at the very beginning, including an unfortunate one with the Tillotson carburetor. To their credit, they have worked tremendously hard alongside us to rectify the issues and we still consider them a valuable partner in the program. In recent months, the 175SSE has been rock solid and drivers continue to praise its durability and longevity. On the event side however, we are still a promotion company. Our customers’ input matters the most and we strive to be as inclusive as we can.”

The 2019 edition of the California ProKart Challenge came to a close at the end of September, wrapping up an astonishing 15th season for the Superkarts! USA regional program. The season was made up of five events, including six rounds of racing toward the championship program for the 17 categories. The year began in Buttonwillow and was followed up by the first double-round weekend at CalSpeed. Trips to Monterey and Santa Maria began the second half of the season before completing the year at the 11th edition of the Streets of Lancaster Grand Prix. Those able to claim a championship or finish top-three in the standings will be honored at the California ProKart Challenge Awards Banquet on October 26.

For the sixth time in seven years, the Croc Promotion USA/Mad Old Nut Pro Shifter category will recognize Billy Musgrave as the series champion — a win streak carried over from 2018 with six wins last season. Musgrave continued that through much of the season, winning the first five rounds before placing second in his Streets of Lancaster Grand Prix title defense. The five victories in 2019 was good enough to give Musgrave his sixth series championship. Jake French, the 2019 SOLGP victor, ended the year in second, with Cody Hodgson in third.

As they have for the past many years, Superkarts! USA put a cap on their flagship California ProKart Challenge season at the Streets of Lancaster Grand Prix this past weekend. The straight-forward yet challenging five-turn layout has always provided exciting racing, and the Lancaster community comes out each year to support the event and cheer on the drivers. The festival atmosphere is always buzzing on Saturday night, with a concert, a car show and countless food vendors. On track, Croc Promotions USA’s Jake French made his second trip to Lancaster a victorious one, as the Texan outgunned his teammate and defending race winner Billy Musgrave for the victory in the Pro Shifter class, while Connor Robles scored the biggest win of his young career, celebrating a Pro Shifter 2 triumph. In X30 Senior, four-time defending SKUSA Pro Tour champion Ryan Norberg of Rolison Performance Group topped the field in his SOLGP debut, while Oliver Calvo came out on top of the KA100 Senior class, which was the largest of the event at 28 entries.

The California ProKart Challenge has the two final events of the 2019 season in sight for the month of September. The penultimate round for the Superkarts! USA regional program has teams and competitors heading to the Santa Maria Kart Track on September 7-8. The fifth round of the California PKC championship chase is set for the ‘Nationals Configuration’ of the Santa Maria, California facility.

The win streak for Billy Musgrave in the Croc Promotion USA/Mad Old Nut Pro Shifter category now sits at double digits. His victory at Round Four in Monterey puts his wins to 10 in a row, dating back to the start of the 2018 California PKC season. Texan Jake French has put the pressure on the last three rounds, stealing a quick time in qualifying bonus points back in Round Three to disrupt his perfect score streak on the year. Cody Hodgson is second ahead of French in the standings, holding three podium finishes on the year. Musgrave is also the championship leader in the Rolison Performance Group X30 Senior division. One win and two other podium finishes put him out front in the title chase ahead of Monterey winner and defending champion Joseph Daniele with a number of drivers fighting for third, led by Jacob Gulick.
