"How can I prolong the life of my IAME Leopard engine?"

Below is the genuine IAME FACTORY DYNO POWER CURVE and TORQUE CURVE.

As you can see, its maximum power and torque is made between 10,000 and 12,000 rpm. There is no need to rev the engine beyond mid-15,000rpm. By not revving the engine over 15,000rpm the engine life will be prolonged between re-builds. The starter motor brushes will last much longer as the engine will not have the high pitched harmonics vibration which breaks the starter motor brushes. By not revving the engine this will also be kinder to the main bearings, big end cage & conrod. By revving the engine over 15,000rpm you are risking a main bearing failure. The load on the drive-side crankshaft would be much less because it has the weight the clutch hub mounted on the side of the crankshaft which may put excess load on the crankshaft if you are revving at high RPM's,
