has anyone had any experience doing custom sc1x installs? just like to know how it went, problems encountered, etc.
While I've never done a custom SC14 install, I think your #1 problem is going to be belt slippage! You need a lot of power to turn a blower at full noise, and I have a feeling that skinny little V-belt isn't "quite" up to the task...
I'll 2nd that.
Toyota used a factory ribbed belt for a reason
Maybe you can use a different crank pulley, or bolt on a gilmer thingo.
