ok, so i want to go with a little smaller pulley and try to get a few more pounds out of my old sidemount on the sub. well i went to south florida pulley headquarters, and ordered the dial your boost system, so i could swap back at any time. well come to find out that wont work with my system, well the guy was cool and i sent it back and he sent me a 2.6 keyed pulley, sinc eim running the 2.8 right now. well that came in a few days ago and i finally felt up to putting it on yesterday, and what do you know it isnt right either, its keyed but its waaay to big for the shaft on my supercharger. what am i supposed to get. why is my supercharger so different? i know its the old system. everywhere i go i hear that. but i bought it 3 years ago and only paid 1500 for it and it added a good 75hp so i thought i got a good deal, and its the family vehicle for trips so i dont need it to be supper fast. anyway im done, i have to call this guy and see what we can do.
