Engine Power Switch
(ZR-1)
The LT5 engine in
your
ZR-1
has two sets of
intake runners and fuel
injectors. The primary set
can be run alone for
normal engine power, or
both sets can be used for
full engine power.
Full power gives you extra power for highway touring
and off-road sports use and reserve power for passing.
With normal power, you’ll notice less engine and
exhaust noise.
To change the power setting, put your engine power key
into the switch. Turn the key to the setting
you
want and
let go. The key will return to the center position.
Your ZR-1 is able to run at full power under the
following conditions:
0
The engine coolant and oil temperatures are greater
than
68°F
(20°C)
but less than
302°F
(150°C).
System voltage is greater than ten volts.
The SERVICE ENGINE SOON light is not on.
You
can switch the setting at engine speeds up to
4,000
rpm. When you select the FULL setting, a light
near the switch will come on.
It
should go out when
you
change back to the NORMAL setting. When you turn
the ignition off, the setting will go back to normal
power.
