Summary
Cardiff Racing is a team of multi-disciplined
Engineering students from first year undergraduates through to post
graduates. This year's entry, CR07, has been designed mainly by
fourth year design students, while the volunteers carry out manufacturing,
marketing and dynamic testing.
CR07 builds upon the experience gained
by the team in previous years. The chassis is a complete monocoque,
constructed from lightweight, high stiffness aluminium honeycomb
composite panels. The sidepods house cooling and electrical systems
allowing space at the rear for more efficient packaging and easier
engine maintenance.
Power is provided by an Aprilia SXV
550 V-Twin engine with optimised intake and exhaust systems. The
engine uses a custom ignition and fuel map developed in-house using
the Cardiff University engine dynamometer. Power is transmitted
through a student designed aluminium spool that has resulted in
faster lap times in testing than a differential.
The suspension system is the lightest
yet from Cardiff Racing, utilising Fox Van RC dampers. Significant
testing was carried out using last year's entry, CR06, in order
to develop driver controls which were simplified to improve gear
changes, and refine the adjustable launch/traction control which
makes the car suitable for drivers of varying experience.
