Ive got a 98 civic with a JRSC and Unorthadox pulley set. After comparing stock Alt length to the underdrive length. The supercharger with the high boost pulley takes a 1245mm belt. with the UR alt pulley, it looks like Ill need another ten mm, as the belt is so tight now, it rubs the cover and the tensioner is as loose as the belt will let it be. So I need about another 10mm in length so the tensioner can move so that the belt doesnt rub. Does anyone know where I can find a 3 rib belt about 1255 MM long? I called bando and after 1245 the next belt they make is a 1500mm length. thats a little much.. anyone have this problem? Id rather keep that pulley on there than switch back to the stock pulley, but if thats my only option... thats my only option

 

get rid of the underdrive pulleys they dont do ****
