I think that kind of makes sense. The stock NA engine sucks ~12 PSI of vacuum at idle, and my Rotrex supercharger offsets that by +~3 PSI at idle. My peak reading at around 25 PSI is when the engine no longer has a vacuum and the blower (without the smaller pulley) is pushing about 9 PSI. Someone else can call BS on me but I think that is what's happening. Thanks!
