see the difference? the black one has no bracket bolted behind supercharger pulley and is what im used to seeing on these, (and kenne belle) yours has a bracket ive never seen in an lsx configuration. the bracket im speaking of actually bolts behind the supercharger pulley using the snout bolts and then has a slotted grove right in front of the outlet to throttle body. never seen that on a whipple or kenne belle. those are the only two side mounts im familiar with other than centrificals. anyone see this bracket before on a ls? i'm just scared id buy it and it doesnt fit. different animal for sure......gene
