Low voltage issue from underdrive pulleys, will be taking them off.
I bought an underdrive crank and alternator pulley and had a TERRIBLE voltage issue, my blazer is not a drag car and I need to it for a daily driver, so this simply won't do. The only way to help this issue is to get a smaller alternator pulley, which I had no luck finding one that fits perfectly. A higher output alternator would help the issue as well, which I do not have one.
I can't elaborate on performance gains for one big reason, I had a bad misfiring issue sneak up on me at the same time of installing these pulleys and I am having terrible engine performance because of it. But I hear underdrive pulleys DO work.
In any case, I will be taking the pulleys off, I simply need the electrical demand for daily driving.
If you need your blazer for a daily driver, underdrive pulleys aren't for you.
Hope this helps answer some questions for those of you that are not sure if underdrive pulleys are for you!
