Jim Wolf Technology can modify. Timing Advantage Moves peak cylinder pressure close to top dead center. Puts more energy to the piston and less to the exhaust, water, and oil. Disadvantage Can build peak cylinder pressure beyond the threshold of detonation. Can forestall detonation by moving peak cylinder pressure further past top dead center.
Disadvantage Can cause high exhaust and water temperatures.
Power will be lost. Cooling effect stabilizes combustion on long wide-open throttle runs. If too rich, fouled spark plugs and loss of power can occur. Many modern engines will produce slightly higher power if the air fuel ratio is leaner by a small amount. Disadvantage Not a recommended technique.
