Has anyone ever taken a stock crank pulley or even a light weight aftermarket one and had it shaved down to where only the alternator belt was used? I was thinking about doing that to my b18a1 to free up some horsepower but I was actually wanting to do it with the stock pulley so I can keep the harmonic balancer. One question would be, does it make the pulley weaker by cutting it down? Basically, I am not using the powersteering or ac so on the pulley it is just dead weight.
