It takes
a high-capacity cooling system to handle over 700 horsepower
during a sustained Land Speed Record run at Bonneville,
so Project Sidewinder has two unique systems.
Two
unique cooling systems are required for Project Sidewinder.
For street use a conventional radiator system is utilized,
while the Bonneville configuration includes a supplemental
water tank that is housed in the bed of the truck.
This added tank also serves double duty as part of
the ballast system.
Street
To
cool the turbocharged Cummins® diesel on the street,
a relatively conventional, if somewhat enlarged, cooling
system is used. The heart of the cooling system is
a large, high-capacity C&R® aluminum radiator.
Multiple thermostats assure unrestricted coolant flow.
Dual Spal® electric fans help move air through
the radiator when the truck is stopped or moving slowly
in traffic. These fans are mounted behind the radiator.
Bonneville
For
the sustained full power runs at Bonneville, extra
cooling capacity assures that the Cummins diesel doesn’t
overheat. An additional coolant tank is installed in
the bed of the truck. This supplemental coolant tank
has the added benefit off providing extra ballast to
improve traction on the salt. A pair of shut-off valves
will allow the supplemental reservoir to be isolated
from the system during engine warm-up.
