Whats this i hear the jackson racing supercharger and aem pullies not mixing well together?

 

I don't know, what is it?

JRSC + AEM Pullies work great together. For the alternator pulley, you'll have to purchase a longer (part #: 6PK1970), and screw with the adjusting bolt to be able to install the belt. Other than that there's no issue.

Don't confuse these accessory underdrive pulley with a crank underdrive pulley, which will lower the rotating speed of the blower (and lead to lower boost levels created).
