i just recieved a set of JE low comp pistons 87mm
very nice looking i must say but the first thing i noticed was that they weigh much less than a standard piston...
now i dont really understand this because for one these pistons are larger and are supposed to be stronger than the standard jobbies so i would expect that they contain more metal due to it being forged to a higher standard?
the standard pistons when clean weigh 5 grams more per piston
is there any other explaination other than they contain less metal?, and are weaker?
