Camshafts Internal Combustion Engine - Parts List

Camshafts Internal Combustion Engine Camshaft Dyno Dynos

Power Curves
Note how all three camshafts create almost identical power curves through 5,000 rpm. By 5,200 rpm, you can see the hydraulic flat-tappet cam begin to nose over while both rollers continue to make similar power up to 6,000, where the mechanical roller takes over to make the most peak horsepower.
