Engine and Transmission
The V8 engine and 6-speed transmission
on Viking XXX are two items that make this car stand out. The
engine block, crankshaft, connecting rods, and transmission case
were designed and manufactured at the VRI by the FSAE team. The
engine block was CNC machined out of aluminum. The heads were
taken from a Kawasaki 250cc 4-stroke motorcycle engine that made
peak power at 19,500 RPM. The 6-speed transmission case was machined
in house out of aluminum, and features internals borrowed from
a Honda 600cc F1 motorcycle. The transmission and engine are fully
stressed members of the chassis and feature mounting points for
The chassis is based upon previous
WWU carbon fiber tube designs with integrated CNC machined aluminum
bulkheads. Viking XXX is the third evolution of this design and
has evolved into a monocoque hybrid based on knowledge learned
from previous generations. The chassis was constructed using the
cut and fold technique developed in Formula One racing. The advantages
of this design are rapid production time, no autoclave required,
low overall chassis weight, and high torsional stiffness. We are
one of only a handful of universities to make any type of monocoque
chassis. The chassis is very advanced when compared to the typical
steel tube frame of other Formula SAE competitors.
Carbon fiber chassis under construction->
The manufacturing processes employed
on Viking XXX are of the highest technology available to any Formula
SAE team. Due to previous VRI research, students have access to
machines such as CNC milling, CNC lathes, EDM machines, and the
latest CAD programming software. Students use lightweight materials
whenever and wherever possible to reduce weight and increase strength.
In addition to titanium, aluminum and carbon fiber were used extensively.
The team takes great pride in the high level of craftsmanship
on this vehicle.
