The
fuel system for the Project Sidewinder combines proven
racing technology with the stock Cummins system to assure
an adequate supply of No. 2 diesel to the engine.
As
with most systems on the Project Sidewinder, the fuel
system is a combination of performance and safety.
The stock fuel tank has been replaced with a 22-gallon
Fuel Safe® fuel cell. The fuel cell features an
internal fuel trap with one-way valves to assure a
continuous supply of fuel during the high G-forces
expected during the road race and handling dynamics
expected from this sport truck. The actual cell is
contained in a standard Fuel Safe metal enclosure,
which is then secured within a framework, constructed
of 1x1 x .090-inch square steel tubing. The framework
is attached to the floor of the truck bed.
The
No. 2 diesel fuel flows from the fuel cell through –10AN
(5/8-inch i.d.) lines to an adjacent Holley® 110
GPM pump, which supplements the stock Cummins® diesel
lift pump in the engine compartment. The fuel then
flows through a stock Cummins fuel filter/water separator
assembly and then to the mechanical high-pressure fuel
pump.
The
common rail fuel injection, which operates under extremely
high fuel pressure, requires electronic control of
solenoids that inject fuel directly into each cylinder.
Exact timing and a duration of one millisecond require
state of the art electronic controls designed by the
Banks® team. The common rail fuel injection system
uses an inlet metered high-pressure fuel pump with
eccentric cam pump, and three pumping elements. The
fuel flow requirements for 700 hp will approach 270
cubic mm/stroke. Common rail fuel injection is a key
element in the ability of the Project Sidewinder Dakota
to reach the performance, economy, noise and emissions
goals established by Gale Banks Engineering™.
Cummins advises their fuel system is capable of supplying
fuel for up to 800 horsepower, which will hopefully
be adequate for our needs. Dyno testing has pulled
700+ horsepower from our modified 5.9L beast!
