I have heard you can't use aftermarket pulleys with a vortech supercharger why is this? I wanted to get some steeda pulleys until i got the supercharger down the road but if i can't use them then what is the point.
its simple. Underdrive pulleys slow down the accesories, the vortech runs off of the accesory drive belt. if you have the pulleys installed and you put a vortech on you will slow down the vortech there fore creating less boost. if you plan on going with any centri blower save the cash put the money twards a wideband autometer widebands can be had for 240-280 depending on the model you want on ebay.
not worth it if you are going to get a blower. You can sale them for 80-100 bucks, but its proboly not worth it since it doesnt sound like you are doing your own labor. After the 180 plus 40-50 bucks for the install your up around 230, proboly not worth the 3-5 Temporary HP for 130-150 bucks.
