I have a ported blower with a 2.65 griptec upper ONLY. Also have an aad adjustable idler. I’m running a K100572hd belt and it is slipping so bad. I’ve been reading different belt sizes and it’s just not making sense lol feel free to chime in

I’d like to run the rpm belt I just don’t know what size

Should delete one of these posts.
Not exactly sure how to do that lol
Better to have a bigger upper AND lower pulley. More area to have friction on belt, yes?
Bigger upper means less boost! We want all the power haha
How do you know it's slipping?
Belt dust all over . And you I feel the car fall out of boost up top.
