The engine for the 2009 car will be a 2006 Honda CBR 600RR. The Motec fuel injection that was used last year will be used again. The race car will be mid-engined with rear wheel drive. The drive train will consist of a chain-driven limited slip differential, constant velocity joints, and custom splined shafts that directly drive the wheels. The chassis design will constitute a new frame. All of the suspension components were redesigned for the new car due to the new template rules. A new composite body will also be designed and fabricated. Modified braking and steering systems from the 2008 car will also be implemented.

2009 marks the University of Connecticut’s first Formula SAE competition since 2001. Our entry this year has been designed with this in mind, accounting for cost, experience, and time constraints. The UConn Formula Racing (UFR) car exhibits a synthesis of elegance, simplicity, reliability, and distinctive design to produce a competitive rookie built racecar, while fulfilling the requirements set forth by the competition rules. With the students and related faculty having no previous experience in the competition and little to no records of past university entries, our goal was to produce a competitive 1st year car that would pave the way for future UFR entries through the expansion of knowledge, creativity, and practice. The design of this year’s car has been executed using appropriate engineering practice. Much of the car’s design has been modeled using Solidworks 2008 such as the casing design for the Zexel Torsion differential and our tubular steel space frame.

Our philosophy is based on four paramount concepts: engineering, team work, project management and simplicity. We worked out the design of the car according to a certain spirit, which puts the emphasis on the components, the fact that the car is simple to build, the innovation and the adjustment. This year the shocks absorbers, the coil springs, the differential, the ECU and the whole frame have been totally redesigned. Moreover, the reliability of some critical components of our car have been analysed with finite elements software. We also used software to make several virtual assemblies to that parts would fit so we won’t have any problems during assembly.

Our Formula SAE was conceived in a systematic approach of technology. Initially, we evaluated what we needed to improve from the preceding model and finally applied these changes to our vehicle. We also checked how each part interacts with each other, using dynamic simulation. The quality of the car is pretty important, but the team has to be extremely well prepared too. This may make a big difference between a team that is forced to give up and a team that may repair the damages in a very short time.

The University of Toronto Formula SAE Racing Team is comprised of a dozen engineering students. In a rapidly changing FSAE series, the UT09 team was able to adapt designs to accommodate new regulations, but also delved forward with higher-level initiatives. While making accommodations for the cross-section template, the front suspension system was also redesigned to help control the ride, roll, and pitch modes more independently. A switch from the previously used F4i to a light-weight single cylinder engine is one of several efforts to improve fuel economy. Extensive engine simulation and dynamometer validation have helped establish a strong foundation with the new engine platform. UT09 also features a second iteration of a CFRP monocoque frame, expanded DAQ capabilities, along with continued development with a custom externally adjustable Salisbury-type differential; and 95% of it all is built by the students. The UofT team looks forward to a challenging 2009 race season with its competitors from around the world and is prepared to defend its top Canadian ranking.

Blue Devil Racing’s 2009 vehicle has seen many changes this year compared to previous vehicles. We now utilize a water-to-air inter-cooler along with our previous turbocharged Honda F4i. Engine parameters are mapped and logged using a MoTeC ECU, which assists in the carry-over of E85 fuel injection. Also new for 2009, is the implementation of anti-squat and anti-dive suspension geometry. The chassis was completely re-vamped due to the regulation changes implemented and also to accomodate the suspension re-design. In 2009 our FSAE team also included LTU’s young Transportation Design program into the design of our body. The entire body was packaged and designed by LTU student, Ben Graf with collaboration between the entire Formula SAE team.

The University of Illinois Chicago presents it first entry to the Formula SAE series this year with our UICM F09. With the UIC Motorsports team being founded last spring we have been working hard to get our car designed and built while still thinking about next year. The goals this year were to make a simple, reliable car that will finish the endurance event of the competition. Utilizing a mild steel space frame and the tried and true Honda F4i was the first step in achieving our goal. We have made many of the key suspension dimensions adjustable to a larger degree than most teams would to give us a bigger range when we do testing before competition. We would like to thank everyone at UIC who has helped us along the way, all of our sponsors who make this possible for us, and all of our friends and families.

SF-F5 is USF’s car for the 2009 competition. Based off of our 2008 car, we refined components while making changes to conform to the new rules. We are continuing the use of a Suzuki LT-R450 single cylinder and squeezing even more power from it with the use of a Garrett turbocharger. Suspension is based off our previous years vehicle with changes to fit the larger frame and to improve geometry. With an earlier start this year, more testing is scheduled to tune the car with the new turbocharger and more focus on driver training.

Hartford Motorsports brings to Michigan the lightest car that the University of Hartford has ever competed with. The team’s design goals for reliability and drive-ability were more than met this year, as the car features a Yamaha YFZ 450 single cylinder engine with an SU carburetor, and an automatic clutch. The combination has proven to be extremely reliable and fuel efficient. The U of H team is proud of the engineering effort that went into making this car easy for anyone to drive and maintain.

Hartford Motorsports would like to thank our sponsors for giving us the ability to build our car, and compete at the international level:

This year’s Tiger Racing team had two main goals: to increase reliability and reduce overall weight of the vehicle. The chassis team worked hard to produce a chassis fitting the new rules while avoiding added weight. The suspension team was able to reduce weight compared to the previous design. And the drivetrain team minimized weight in the engine mounts while ensuring strength and rigidity. Meanwhile, the drivetrain and electronics teams worked to fix last year’s reliability issues by designing a custom cam trigger wheel that would allow for more precise tuning, and by converting their engine from CDI ignition to digital ignition.

The design of the 2009 Michigan Wolverine focuses on vehicle dynamics performance and powertrain calibration supported by reliable subsystems. To these ends, the design consists of a 185kg spaceframe car with 10” wheels powered by a naturally aspirated 4-cylinder engine with E85 fuel and dry-sump oiling. Highlights from a mechanical standpoint include fully adjustable kinematics, custom Penske dampers, in-house designed brake calipers, internal CV joints, and a Nylon SLS intake manifold. To improve powertrain control, the vehicle uses a BOSCH Motorsport ECU with closed-loop fuel control, traction/launch control, and a shift fuel cut. The vehicle is tuned to suit a range of amateur drivers with cockpit-adjustable ergonomics, engine maps, traction control, and brake balance. Combined, these features provide the MRacing team with a platform capable of reaching the highest levels of the Formula SAE competition.
