I guess it probably doesn't, as it's been like it for a while with the current set up. I'm taking it to MSL on the 12th August for a check up so if there are any belt issues they will be able to tell me!Belt wrap kit as the name suggests is designed to prevent belt slippage. I'd just get the right belt length instead. Especially if you don't know if you belt slips.
I have the 77mm pulley & Headers done at Msl, with no Bwk. Acid is not a fan, or at least he certainly wasn't previously. My 77mm pulley has been good as gold without one for ages. Think it is the Americans that are bigger fans of the Bwk than us, on average.Ok cheers.
What about if I decide to go for more power?
You're a brave man driving tonight with no ESP..needed a boat in my part of Bucks..are you sure you're getting belt slip coming off the throttle?I got some belt slip tonight. Had the esp off, tyres lit up and then as I let off the throttle fully I heard the belt slip for a second or two.
The belt looks ok but i am no expert.
