dzieki Tomo, ale to w koncu dla moich tlokow ktores sa zrobione z 4032 aluminium to jakie ma byc ? 10-15 setek ? bo znalazlem taki opis w necie jak poznizej


"SRP Pistons are designed for street/strip applications utilizing many compression ratio combinations compatible with pump gas as well as moderate turbo boost and nitrous oxide. SRP sport compact pistons are forged from 4032 low-expansion aluminum alloy for smooth and quiet operation. JE designs are specifically engineered for extreme applications up to, and including, professional competition. In this environment, the higher compression ratios, highest boost or heavy nitrous usage necessitate the higher tensile strength 2618 aluminum alloy, other features are listed below.

Coefficient of Thermal Expansion

2618 aluminum expands approximately 15% more than 4032 aluminum, thus the 2618’s initial piston-to-wall clearance has to be 15% greater. This difference is most noticeable during a cold engine start. When cold, the 2618 piston can rock back and forth producing a slight noise until the aluminum expands. Both types of aluminum have approximately the same clearances once the pistons have expanded and the engine is running at operating temperatures."

Dla 4032 wychodzi 5 do 7 setek jezeli nic nie pomylilem. Raczej trzymac sie wyzszych wartosci.

Na 10-11 nie mialem nigdy problemow - trzeba tylko sprawdzic luz na zamkach pierscieni.
