Could u or someone explain this... I understand y u would say its the handbrake, because the noise happens in a revolutionary manner (wheels spinning) hence the handbrake.If its the handbrake it should occur all the time, I dont hear it driving normally, I only hear the noise when accelerating hard and on boost. Just seems logical to think boost leak as its an air type sound not really a rubbing sound. bluprinturbo Im not, not agreeing with u as I dont have a clue and its something ill definately look into. Has this happend to you? How much to get fixed? What do I tell the mechanic to look for? Thx Mike...
