Typically cams for high-rpm N/A applications arent boost friendly, especially very aggressive profile ones. The high lift and overlap creates a scavenging effect for better N/A airflow, but when you add forced induction, the boost can just blow right in and out of the cylinder because of this. This is not to say that cams wont work with the kit, but it just depends on the profile and spec of the cams. :thumbup:mik3 agby said:thats gay. dont know why you cant use cams with the AA kit.
