I have an aftermarket air filter on it, and I recently replaced the fan clutch. But this thing is loud! My 350Z (same size engine btw) creates a beautiful growl but doesn't have anywhere near the loud, whirring noise that comes from the engine of the VX...

any idears?...
Though not coming from the engine compartment, I wonder if you have a PV2 muffler on. Power Vault made mufflers specifically for our VX and the second generation PV was VERY loud. Too loud for many.
