[QUOTE="singlespeed, post: 119338, member: 264"] camshafts are often classified fast road/rally... As a guide to the performance power/revs caused by changing the valve opening lift and duration. Pistons would be avaliable in different compression ratios. Lowering the compression ratio would allow a higher boost pressure to be run, giving a higher output when the turbo is at full speed... But, lower CR would give less power when off boost. For NA motors, forged pistons tend to be higher CR which helps increase power, but not as effectively as using a turbo/supercharger and a lower CR. Forged pistons tend to be lighter and stronger than the equivalent cast piston, allowing a higher rev limit (if the pistons were the limitting factor ) Forged rods with high tensile bolts will take higher rpm and also higher piston pressures (torque) which may bend a standard rod.
