Frustrating and at this point costing my summer to drive this car but it's just not happening. The new pipe welded on did nothing to dampen the load siren type noise at idle and at this point I'm thinking it could be a combination of things with the inlet. The large sheet metal inlet being rectangular could be causing the harmonics as it has long stright panels of .081" thickness. The sheer size must also add to the aplification of the rotor noise. Also the material may have something to do with it as KB uses cast which may due better a dampening the sound.
At this point I'm gonna try fitting the stock Flowzilla back and see what I get. Also seems that it heats up very fast and is so hot that you will burn your hand if touching the blower case. I'm not sure if I'm imagining it being hotter that my 2.1 use to run or it really is. At this point water does not boil up on it thank god but it evaperates fast, just dont remember it that hot. By pass is functioning, but maybe the fast idle coupled with the amount of boost its set for is causing it to generate nore heat.
