Belt size for 168 crank + 80 supercharger with BWK
Does anyone know the correct SC belt size for a 168mm crank pulley, 80mm (custom) supercharger pulley, and a belt wrap kit? I'm currently running a stock belt (belt wrap kit bypassed) and it works but it's a bit tight. I previously tried it with the belt from a previous 168mm+77mm combo (whatever size Shardul recommended for that) but it was too tight and the belt shredded pretty quickly.
Has anyone come up with a formula for calculating belt sizes or is it just a matter of trial and error (with most of the trial and error having already been done with normal combos)?
Assuming that no one knows the correct size, can someone please tell me the correct size belt for a belt wrap kit with stock pulleys? (Since a stock size belt works sans BWK (but is tight), I should be able to get away with just slightly larger than what's recommended for BWK with stock pulleys.)
Thanks in advance!

Thanks! That's exactly what I needed to know! The size with stock pulleys is K080530 (thanks to gjunon), so as I suspected, the correct size should be just a bit bigger.
