i am on search of the weight of the ATI dampener pulley
i found 4,5 kg without the AC parts 5kg complete

does someone could confirm this?

i weight the OEM one on my 7MGTE spare engine it weight 4,9KG

i seen lighter pulley like ralco or OBX but they are undampened and i am a little bite scare about this even if i am not running AC or Power steering

so i am asking myself if its a good things to burn $$ on such parts


on this spare engine i am starting to build , i want to lightened the rotating element to kill some torque and have a better rotation/rpm
my car is light so i don't need a lot of torque to move it and i prefer this way to run

anyone have done such mods ?
