5200 RPMs, eh? That must explain the sound I hear right at that RPM when at WOT. The pitch suddenly change right about there and gets louder, which always reminded me of the Variable Intake System on my mom's 05 V6 Altima.. which sorta does the same thing but supposedly does it with having two intake paths.
I like VICS, I just don't like it's screws in my combustion chamber (ughdance)
I really need to pick up a spare intake manifold. Once I have some money saved up when I start my job in June, I'm definitely picking one up and either doing the work myself (living by myself in my apartment all summer 6+ hours from my friends will get quite boring I'm sure) or having a competant machine shop do port/polish on the manifold or something.
