which upper pulley do i have?

[jboehm]

i have the YSi passenger side renegade kit. Currently run the supplied blower pulley but i am not sure if it is the 3 inch or the 3.12 inch. anyone know which one they send with the kit. also , thinking of stepping up to either the 2.85 or the 2.80. does someone have real world results from such a swap?

They send a 3"/8" combo with the kit normally.
