I have a 2014 MX5 with a Kraftwerks supercharger and I have been slipping the serpentine belt at around 6000 rpm since I installed it in April. I am going to install the 2.5 tensioner and some other pulleys like I have seen suggested. My question is does anyone know if this will work and if you know what brand and part number the belt is. A replacement belt from Kraftwerks is $150 I think that is way to much since I can probably get it from Gates or Dayco for a third of that price. Any info would be greatly appreciated.
Thank you Scott
