So I have the 2.8 pulley on my car. Mods are in my signature, here my problem. I guess from the sheets from the dyno and from what they guys were telling me is my belt is slipping. I have asked people how they fixed it. I was told about changing the pulleys, but what ones? All of them? I changed out the idler but it was to big so I had to put it back. Any ideas on how I can make the belt grip??
