dont know if it affects the 7m's alot but when u put on a set of lightweight crank pulleys i might get crank walk. but pulleys like alt. ps a/c those are fine to get light weight

The stock crank pulley has a rubber type insulator between the inside part and the outer ring that the belts go around. So it basically absorbs vibration. People run with the lightweight one but it does not have any vibration dampner in it to it allows the drivetrain vibrations to go thru the whole motor much more violently. I haven't heard of anyone's engine exploding or anything yet tho. Alls I know is I run stock, and stay stock :icon_bigg
Unless you're talking turbos :biglaugh:
