Velocity Racing Turbo Busa Various Components
Hidden under the bodywork are various components involved in the control of 500-plus horsepower. The three gauges under the seat show pressure for the air shifter, water injection and boost control, which are all fed by the remote air tank mounted on the rear. The aluminum tank just in front of it is the reservoir for the water injection, with the boost controller situated forward of the reservoir.

Velocity Racing Turbo Busa Intake Plenum
Underneath the fuel tank is the custom-fabricated intake plenum for the Velocity turbo system. Note the Tial blow-off valve (which releases boost pressure when the throttle is shut to avoid turbo backpressure) just in front of the plenum.

Velocity Racing Turbo Busa Crankshaft
The new stock Hayabusa crankshaft now has grooves cut into the main bearing journals for improved lubrication at higher pressures. Although the overall crankshaft weight is the same as the '07 model, the counterweights appear to be wider and thinner than before.

The new '08 piston (left) no longer has the shallow dish in the center of the piston dome, which helps to increase compression slightly. Note the slimmer skirt design on the new piston. Piston/ring assembly weights are identical at 220 grams.

Velocity Racing Turbo Busa Stock Rod And Piston
Although the new stock rod and piston pin on the left look very similar to the old components on the right, a close examination shows some small changes to the rod design for '08, as well as the smaller-diameter/thicker-wall pin design for the new model. Rod weights are identical, but the new piston pins are 20 grams lighter, a substantial decrease.

Velocity Racing Turbo Busa Stock Components
The Falicon Knife rod and JE turbo piston are far stronger and more durable than even the new stock components, a necessary change to handle the incredible power of the Pro Street turbo engine.
