Thought I would share the old published break-in procedure for Dodge Viper engines. Keep in mind that the 8.0 liter Viper engine red lines at only 6,100 RPM. I am using this procedure on my GT350 with proportionately higher rpm shift points each 200 miles. I have about 650 miles on my car but I have yet to rev the motor over 4,000 rpm. Each 100 miles I will raise the maximum shift point by 500 rpm. After 1,000 miles and my first oil change will be the first time I consider any wide-open throttle maneuvers or taking the engine to red line.
The following break-in procedure is suggested for any NEW Viper engine.
During the first 1000 miles (1610 km):
1. Avoid long periods of engine idling.
2.Wait until the engine has reached operating temperature before driving
enthusiastically.
3.Check the engine oil level at each fuel
fill since a new engine may consume some
oil during the first few thousand miles (this is normal and not a sign of an engine
problem).
4.Keep vehicle speed below 70 mph (113 km/h).
5.Do not make any full throttle starts or full throttle accelerations.
6.Avoid driving at a constant engine rpm for long periods as follows:
!First 200 mile interval (322 km), light throttle run-ups shifting at a maximum
of 2500 rpm. In addition, It is suggested to change the engine oil within the
first 200 miles of engine break-in.
!Second 200 mile interval (322 km), light throttle run-ups shifting at a
maximum of 3500 rpm.
!Third 200 mile interval (322 km), light throttle run-ups shifting at a maximum
of 4000 rpm.
!Fourth 200 mile interval (322 km), light throttle run-ups shifting at a maximum
of 4500 rpm.
!Fifth 200 mile interval (322 km), light throttle run-ups shifting at a maximum
of 5000 rpm.
