[QUOTE="wildturkey, post: 16289560, member: 94810"] Thanks for the reply. We put mine on the dyno and noticed the dip at 3500RPM, so we took it to 4500 and the dip was less pronounced. Then we went to 5000 and settled at 4700 RPM. The rattling seems to be the shaft when the butterflies are closed. I'm going to check out a Lincoln Aviator intake pretty soon, to check the similarities. I know they are quite, but they fail closed where the FR500 intake fails open. The Aviator engine may have less cam and degree to run smoother. At this time I have disconnected the window switch and left the butterflies open. Read ya later, Nick [/QUOTE]
