CAM AND BARREL
The Cam is the shape around the skirt of the piston and the barrel is the shape from under the oil ring to the bottom of the skirt. Extensive research and development has been done to find the optimum skirt shape for each piston. These shapes have been found to seal up cylinders and reduce harmonics in the bore better than ever before. Depending on the forging and application, different cam and barrel profiles are utilized for maximum performance. Having the correct cam and barrel on a part promotes the following:
1. Tighter clearances
2. Less noise
3. Better ring seal
4. More power
5. Increased durability
Also know as contact reduction grooves, which limit the piston/cylinder contact during high temperature and high RPM. These grooves also protect the top ring by disrupting detonation waves.
ACCUMULATOR GROOVE
V-shaped groove machined in the 2nd ring land that adds to the volume between the top and second ring. This groove accumulates residual gasses from combustion which alleviates top ring flutter and premature second ring wear, improving ring seal.
Double Pin Oilers (opposed to single pin oilers), in conjunction with our annular reservoir, can add twice the amount of oil from the cylinder wall to the wristpin bore. This is a standard option on any piston that receives forced pin oiling.
BROACHES
Broaches are horizontal slots in the pin bore designed to allow oil to enter between the wrist pin and pin bore. Broaches are also used to accommodate the wrist pin shape under compression, as it can become somewhat oval and needs room in order to alleviate galling.
The pin bore is precision honed to attain an exact pin clearance. Depending on the application clearances typically range from .0003 to as much as .003 between the wrist pin and pin bore.
