ENGINE OVER-REV
Note:Engine torque and maximum rpm are limited until coolant
temperature reaches 170°F (77°C). Warm up is indicated when the
redline indicator band starting point changes from 6250 rpm to
7000 rpm.
Your vehicle is equipped with an over-rev feature to increase the
performance range of your Shelby GT500. When conditions permit,
over-rev is indicated on the tachometer with redline marked at 7000 rpm.
If conditions limit over-rev accessibility, the band is illuminated red from
6250 RPM to 7000 RPM.
Once the engine is warm, the over-rev feature allows eight seconds above
6250 RPM up to 7000 RPM. If the eight second time limit is exceeded,
the maximum engine RPM is reduced to 6250 RPM until both of the
following occurs:
•Engine is operated for at least 15 seconds below 6000 RPM
•Engine RPM falls below 5000 RPM.
Do not operate the engine at high RPM and low load for sustained
periods of time, as damage may occur.
