what kind of increase in power should i see at the rear wheels after i put my FMIC on? its a homeade kit....forgot dimensions but it is a bigger one with 3" piping. i have a 10# pulley now and will prolly have to put a smaller one on for the same psi....correct? thanks in advance for your input guys. :SNSign:
 
without a pulley swap you'd probably see a 5-15hp increase. with a pulley change probably 30-40. it's all going to depend on the efficiency of the intercooler and the amount of timing added.
