comparison with single bearing Is having the double bearing better than the single bearing version?

  • Yes 2 bearings make it more stable and giving you a longer lasting pulley.

I have a 2008 roush stage 3 mustang , have installed these parts from you ford hot cams ,headers ,cold air intake, bama tuner. at idle the idler make noise because of the cams will the auxiliary pulley kit take care of this problem ? and can I puy a smaller pulley on it to get more boost ?

Chuck

  • Unfortunately, this part does not work on ROUSH cars. Your motor is a 4.6L, this bracket is made for the 5.4L GT500 which use a totally different platform. You idlers should not be making noise regardless of cams or idle speed. I suggest you remove your supercharger belt and spin each pulley by hand. You will find one that is rough, loose or gritty feeling. Replace it. I have had issues with aftermarket billet pulleys where the bears keep failing prematurely. Stick to the boring factory pulleys, they last a lot longer. To get more boost, you need to buy a smaller supercharger pulley and a bigger idler pulley; trying looking at VMP Tuning for supercharger pulleys.

    GT500 double bearing idler

    Product is made very well. Solid and sturdy on car. I rtv'd the spacers to hold in place while I put the bolts through. Have not had the chance to use with smaller pulley but will see then if it help with slipping. I am very pleased with my purchase. Metro has always made exceptional product.

    Idler pulley install and performance

    We changed the blower pulley to 2.6 and had belt slippage with the stock belt so I installed the Metco Motorsports Idler pulley in about a half an hour and eliminated the belt slippage. Great looking polished aluminum, nice addition to the under hood look. SAE dyno 538hp 525 torque.

    Excellent Aux Pulley

    Installed this Aux Pulley in conjunction with a smaller supercharger pulley. Provides more belt wrap around the SC pulley and helps to eliminate belt slippage. I'm very happy with the result. Aux pulley works great and looks good as well. Easy installation. A bit expensive, but I felt the extra bucks was worth it for the double bearing set-up. AM recommended this item and I'm glad they did. Thanks AM!
