I did a search and couldn't quite find the answer I was looking for. I'm seeing noticable belt slip, and can also feel the boost cut in and out when hammering it. I had an oil leak that got onto the belt. Still have the vortech supplied belt on there, had a advanced auto belt on there for 24 hours before i shredded it. Fixed the oil leak, but is the belt trash now? Is there anyway to clean the belt? I also have the factory tensioner on the car with 70K miles on the car. Knocked off the tensioner stop for more travel. What is the best belt to get and do I need a new tensioner, and what is the best one for a REASONABLE price? THanks.
