6-26-17 update: Hours of testing. Prepared drivers. A reliable car. A top finish in the all-important, 14-mile endurance race at last week’s Formula SAE Lincoln event in Nebraska. Add them all up and you get “great results” for the Iowa State Formula SAE team, said Nate Lenz, a senior in mechanical engineering from Sioux Falls, South Dakota, and the team’s technical director. “We took fourth overall. That’s even better than last year. It’s the best finish Iowa State has ever had.” The 2016 team finished fifth overall among 70 scored teams in Lincoln. But this year was even better: fourth in the endurance race, fifth in skid pad cornering and sixth in the short, twisty autocross time trial. Another 3.1 points (out of 1,000 possible) and the team would have finished third overall among 77 scored teams. But Lenz wasn’t complaining about the fourth-place trophy. “I’m very proud of our team and the effort made by multiple members,” he said. “It was a great team that came together – and some great driving performances. We’re all very proud of where we left Cyclone Racing after Lincoln.”
AMES, Iowa – They’ve already run four parking lot simulations of the nearly 14-mile endurance race that’s such a challenge to students and their mini open-wheel racing cars.
They’ve already solved a few problems during their season-opening competition earlier this month at Formula North in Barrie, Ontario, Canada.
They’ve already figured out how to drop their car’s weight by almost 25 pounds and how to engineer more efficiency into their car’s front and rear wings.
And so the student-engineers who designed and built Iowa State’s formula racer are looking forward to the season’s final test June 21-24 at Formula SAE Lincoln in Nebraska. The competition is sponsored by SAE International, formerly the Society of Automotive Engineers. Last year, Cyclone Racing left Lincoln with a fifth-place trophy (of 70 scored teams).
“We definitely had high hopes for Formula North,” said Nate Lenz, a senior in mechanical engineering from Sioux Falls, South Dakota, and the team’s technical director.
But, as often happens at these competitions, an unexpected component failure made for some quick thinking and some fast repairs. In this case, the custom muffler built by the students wouldn’t pass noise inspection. So a plug went in. That cost the team some power and it eventually caused the muffler case to blow out.
The team, however, came away with top-10 finishes in cost of manufacturing, design engineering and skid-pad cornering. Overall, Cyclone Racing finished 16th of 25 scored teams.
Now the car is back in the team’s campus shop and Lenz thinks the team is in good shape.
A heavier, stock muffler will replace the custom one. But that’s partially offset by taking nearly 25 pounds off the weight of last year’s car by building lighter wings and eliminating radiator covers and other body work.
In addition, Lenz said the car’s over-the-top, gooseneck mount for the rear wing has increased aerodynamic efficiency. The new, push-button shifting system has been good for the drivers. And the high-compression piston is boosting power.
So the car is fast?
“It definitely is,” Lenz said. “We have a good opportunity to be fast in Lincoln.”
And all those long simulation runs?
“We’re really proud of those,” Lenz said. “We hope to translate them into performance on the race track.”
