I bought my xkr off of my buddy after he bought a new one. I at one point told him he should get a supercharger pulley and a port job on his blower. This was years ago. And he never mentioned getting it done. So I pulled my car apart and well....The blower was ported. Now I was looking at the crank pulley and it doesn't look factory. It looks like hard coat anodized aluminum. What do you all think?

 

After doing some searching...Appears to be a eurotoys pulley...May need to add that Methanol....that and my 10% pulley may be a bit to much
