    Hello everyone, I recently installed a Way Motor Works 15% reduction pully along with a Way Motor Works tensioner stop new tensioner and new idler pulley. After installing everything I drove it around and everything was fine. The next day after work I was just driving through town and I started hearing what appeared to be a belt squeal around 3k rpms all the way up to redline under light and heavy acceleration. I put my stethoscope around the belt area and it appeared to be the tensioner. I reimstalled my old tensioner and again the noise was gone for about a day then it started up again now at 2500rpm and up. I was wondering of any body here had encountered this. Thanks you for reading anything helps

    Did you put a new belt on and is it sized for the 15% pulley?

    I never recommend the tensioner stops. They're an answer to a question that's rarely asked, and cause more problems than they solve, like not allowing free and full movement of the tensioner pulley.

    Hi everyone, yes I did put on a belt for the 15% pulley I actually bought another one and will install it tomorrow after work.

    Eric, I was just thinking the same thing since the noise comes from the tensioner I am going to leave it off when I install my new tensioner on tomorrow.

    Thanks guys I appreciate the input, this mini is the first supercharged car I have ever owned, everything else I have had were Japanese turbo cars so its definitely interesting not to mention how involved any sort of work is. Thanks again I will update after the install tomorrow

    If you have installed the tensioner as per the picture on Way's site it is going to rattle a lot. It needs to be swapped end to end. The end with the slot needs to be attached to the spring arm of the tensioner.

    Hi everyone, well after many attempts to up load a sound clip of the noise I was in able to. But I did manage to fix the noise it turned out to be the belt. I don't exactly know how the new belt I put on happen to fail but it did. Thanks again for the help everyone.

    Thanks Nathan I will check into that tomorrow, is that a common issue with the R53Ss to get sharp edges on the pulleys? What causes that I have been an automotive technician for 12 years now and I have never encountered that.

    Debris getting caught in one of the pulleys is common.
