When building your MINI Tritec 1.6L bottom end, you need a quality Piston that can handle boost and maximum horsepower. CP forged pistons feature superb ring seal, higher vacuum, lower blow-by, greater durability and increased horsepower and torque through the powerband. Better yet, peak horsepower is retained through the life of the piston rings. This is achieved by lightweight forgings and CP's exclusive machining techniques and processes. CP's commitment to racing is reflected in every piston they produce.

CP is dedicated to superior engineering, utilizing the latest forging techniques and CNC machinery and backing it up with rigorous quality control makes for a top-notch product every time that emphasizes performance and reliability. CP has some of the highest quality control standards in the industry. CP is a division of Pankl Racing Systems, a high-technology racing group supplying engine and suspension components to numerous Formula One, F3000, IRL, CART, World Rally Racing teams and to such elite companies as Ferrari and Porsche. You will not find a finer piston for your Mini.

Select Bore size. Available options:

[ ] Standard 77mm Bore with 8.3:1 Compression
[ ] 77.5mm Bore (+0.5mm) with 8.3:1 Compression
[ ] 78mm Bore (+1.0mm) with 8.3:1 Compression

ADDITIONAL FEATURES:

Anti-Detonation Grooves:
Are grooves that protect the top ring by disrupting detonation waves. Also know as contact reduction grooves, these grooves limit the piston/cylinder contact during high temperature and RPM.

Accumulator Groove:
Is a V shaped groove machined in the 2nd ring land to collect excess blow-by between the top and second ring. This groove collects residual gasses during combustion and alleviates top ring flutter while increasing ring seal.

CP groove:
stands for Constant Pressure Groove. This groove works as a channel on the lower part of the top land that equalizes pressure to the back of the top ring groove. When used in combination with lateral gas ports, the CP groove helps keep gas ports clear of carbon build up. In addition, the CP groove prevents the top land from smudging into the top ring if the land rubs the cylinder bore.

Double Pin Oilers:
in conjunction with their dual fed reservoir add twice the amount of oil from the cylinder wall to the wrist pin.

Cam and Barrel:
Extensive research and development has been done to find the optimum skirt shape for each piston. Having the correct cam and barrel on a part promotes the following: Tighter clearances, Less noise, Better ring seal, More power, Durability. Depending on the forging and application, different cam and barrel profiles are utilized for maximum performance.
