BANKS POWERPACK ® SYSTEM
GM 454 MOTORHOMES
P-30 CHASSIS with FUEL INJECTION
Dear Customer,
Your new Banks PowerPack is a unique combination of air intake, exhaust,
and transmission components designed to make the most of your engine’s
power potential. By removing intake and exhaust restrictions, providing cooler
intake air, and tuning the exhaust to create a scavenging effect, your engine
can produce more power at a higher level of efficiency. To take advantage of
your new found power, this PowerPack includes a transmission governor
recalibration kit to raise the shift points of your automatic transmission, as you
now have a higher usable engine RPM range. If your driving habits remain the
same, your fuel mileage should go up, and you can run on the same octane
fuel you are accustomed to using.
IMPORTANT REVISION:
If your motorhome is equipped with the electronic 4-speed
automatic overdrive transmission, omit steps 36 to 43. The
transmission governor recalibration kit is used only on the 3-
speed automatic transmission. Some extra parts may be
included subject to this revision.
If you have any questions concerning the installation of the Banks PowerPack
kit, please call Gale Banks Engineering at (626) 969-9600 between 8:00-
5:00 PT and ask for the service department.
Thank you.
