2. PERFORMANCE 2-1 MAXIMUM OUTPUT The maximum output is the output of a .n engine with its throttle valve fully open led under the c mdition that all the moving parts are properly broken in after the initial break-in period. A new engine may not produce full maximum output while its moving parts are still not broken-in. NOTE : Power curves shown in the following charts are made in conformity with SAE internal combustion engine standard test
