your Banks stinger will allow your GM 6.5l factory
turbocharged engine to produce more power and
respond quicker well within the safe operating range
of the engine as long as the following guidelines are
adhered to.
use your pyrometer (exhaust temperature gauge)
and boost gauge to monitor your engine’s operation.
at idle, egT (exhaust gas temperature) will be very
low, perhaps only 150°f. as the throttle is opened
for higher speeds and greater loads, the egT will
rise. The highest egT will be seen under maximum
load at full throttle, such as climbing a steep grade
with a heavily laden vehicle. use caution if your egT
approaches 1000°f, with 1050°f being the safe
MaxiMuM!
if the vehicle approaches these egT levels under
these conditions, downshift the vehicle to reduce
the load, or back off the throttle.
exhaust gas temperature in this system is measured
“after” the turbocharger in the turbine outlet pipe, as
is commonly done on long-haul diesel trucks.
Your boost gauge monitors the air pressure the turbo
compressor is delivering to the intake manifold.
The banks stinger system is designed to provide a
maximum boost pressure of approximately 10-11
psi. This is an average maximum figure which will
vary from engine to engine. This maximum figure will
be reached only under hard acceleration/heavy load
conditions. light cruise conditions may show little or
no boost.
iNJectioN PUMP AdJUstMeNt
if your exhaust gas temperature is consistently well
below the 1050°f safe maximum under full load
conditions (steep uphill towing with maximum load),
you may obtain additional performance through an
adjustment of the fuel injection pump to provide greater
fuel delivery. if the egT tends to exceed 1050°f, the fuel
delivery must be reduced.
The pump adjustment is made by turning an internal
allen screw, found within the pump. be sure to adjust
the pump with the engine and pump cold. in most
cases, turning the screw 30° (one half flat of the allen
wrench) clockwise will bring the egT into the proper
range if the egT is low. keep in mind that increasing
the fuel delivery will also increase the smoke output of
the engine. some states, such as california, have a 40%
maximum smoke opacity limit during a snap throttle
test. check the emissions regulations in your state
before altering the injection pump setting.
The pump adjustment can easily be set with the
pump on the vehicle. if the condition of the pump is
in question, or if the pump is to be removed from the
vehicle, gale banks engineering can provide the
addresses and phone numbers of qualified association
of diesel specialists (ads) pump service shops.
