I'm pretty interested in the Code3 pully for the C32 supercharger, the performance seems like a reasonable increase, and more HP is ALWAYS better right?

My question is about the supercharger noise as heard in this video link. Now superchargers are cool and a little whoosh or whiste is good, but this seems extreme. Now I don't anything about he car or the recording but was hoping some of you may have done this mod and can give me a real, true opinion of the noise after the install? And the general performance and if your happy with the pulley/car after installing it. Thanks - video link below
