Alex,
When I first bought the SC it came with a 9lb pulley then they had some problems and they sent out a 8lb pulley no new belt needed. So I thought that the original belt would be fine. National Speed said the belt may have stretched over the 9k miles I have put on the car since I have had it installed. NS called Stillen and they said oh well you should have ordered the belt with the pulley... I was not very happy with Stillen when I was told that. NS ordered a smaller belt and it still slips. So today we will find out what is going on with the car. Fingers crossed.
