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

Better to have a bigger upper AND lower pulley. More area to have friction on belt, yes?

I know, but maybe a 2.somethingabitbigger and a 10 percent-larger lower would reduce belt slip for same boost.
Plus having that wonderful high-friction coating put on the pulley that someone does somewhere.
