Following Sunday’s second race in the 2023 Bridgestone CSBK National tour at Shannonville Motorsport Park, the top five finishers in the GP Bikes Pro Superbike Feature category went to the Official series Dynojet Dyno.
For twenty-five years, Brooklin Cycle Racing of Pickering, ON, have operated the portable Dyno at each venue, assisting with competitor’s tuning needs early in each event and then measuring motorcycle performance for rules eligibility during Qualifying sessions and final National races.
Many Bridgestone CSBK competitors also visit Brooklin Cycle’s race shop to use their permanent Dynojet Dyno for initial tuning and engine set-up, and other Dynojet Dynos also yield comparative data to help racers prepare for National rounds.
The GP Bikes Pro Superbike category was under extra scrutiny, since the maximum allowable horsepower for this class had been increased from 200 to 210 HP over the off-season. With only one long straight, Shannonville’s Pro perimeter layout is not focused on top end performance, but every advantage is meaningful in the Pro Ranks.
Following Sunday’s race, the BMW S1000RR of Samuel Guerin registered the highest horsepower on the Dynojet Dyno, measuring at 196.35 HP.
In the 22-lap race, Guerin placed second, having battled for the lead in the early going. The fourth year Pro had taken control in Saturday’s wet opener, before a crash exiting the hairpin spoiled his effort. Former flat track great and Canadian Motorcycle Hall of Fame member Steve Beattie looks after Guerin’s machinery at each National venue.
It is likely that reigning Champ Ben Young’s brand-new BMW M1000RR would have produced a similar output, but Young placed sixth after a pit stop and was not required to run on the Dyno post race. Young turned the second fastest lap of the race and earned the FAST Riding School Hard Charger award for his run back up the field.
Young’s BMWs, tuned by Scott Cartier and Willie Vass to two overall National number one plates, have regularly been among the top three machines for output post race.
Engine torque is not restricted by the rules, and this performance element might be more important than the often-discussed outright horsepower output.
Second best Superbike output came from the third placed LDS Consultants Kawasaki ZX-10R Ninja of 14-time National Superbike Champ Jordan Szoke, registering 190.83 horsepower. “Jordan of the Jungle” placed a close third in the race. Szoke’s Kawasaki power plants are built by Fast Company, a long-time partner of the Waznie Racing group that now includes the injured Trevor Dion.
The winning Purple Skull Brewing Suzuki GSX-R1000 of Alex Dumas was third best at the Dyno, close to Szoke with an output of 190.67. In his third year in the Series, 2021 Champion Dumas has ridden bikes prepared by Patrice Goyette of MPG, dating back to his earliest efforts in Mexico.
The Yamaha Motor Canada backed YZF-R1 of “T.V. Tommy” Casas ranked fourth in the overall post-race horsepower category, the cross-plane crank equipped inline four cylinder measuring 183.15 Dynojet certified horsepower. Casas was fifth in Sunday’s dry race, after earning a strong third with the Parts Canada supported R1 in the rain the previous day. The powerplant for the Casas Yamaha is also prepared by Fast Company.
Rounding out the top five was One Speed’s Trevor Daley on another Suzuki Canada backed effort, with a total of 180.78 horsepower produced by his fourth overall GSX-R1000 entry. Daley and Casas spent most of both the opening Nationals at S.M.P. in each other’s company, on track.
