@D-VO
Seems like your best bet is to use a dial indicator with a magnetic stand to measure runout. Either one of your idlers, supercharger pulley or crank pulleys can cause the belt to change tension as you rotate the crank since it is a cogged system. Heck, even an unevenly stretched belt could cause that. So many different variables.

It seems like the OP @digital_assassin has sold his 86 and no longer visits this site. Is there any way I can take over and update the first post? I would like to update the replacement belt part numbers as the one listed is no longer relevant. I ordered the wrong one because the post is outdated.

Thanks
