This is good stuff I've been trying to find some decent info on people making there own cai's. Made a few flashing's for work (chippie) and thought why can't I make a custom airbox.

The fg standard setup is a bucket load better than ba/f.

Had a heap of trouble trying to get my XR8 box and snork to clear my hard pipe hit perfectly, so in the end ditched it for an SS Growler.

The first thing I noticed was the induction noise, especially just on boost, was significantly louder over the V8 airbox. I actually didn't like it at first to be honest but keep in mind, I'm an old fart. The wife (god love her) hated it - said it mate it the car sound 'cheap'. Bitch! Anyway, it got me thinking. Given I run the plazmaman inlet muffler replacement, I wonder how she'd go with the OEM part fitted back on so I did it this arvo.

With the OEM inlet muffler refitted, the annoying 'swirling' noises under light pedal or just on boost were virtually gone. Still get the blow off 'psss' and 'tu tu's', but a lot quieter. The downside is, you lose spool noise which is why most of us piss the OEM muffler off. I've refitted the plazmaman pipe as I also prefer the under bonnet apperance with it on.

I don't know if a turbo side would suffer from the same problem given the removal of the crossover etc. All I can say is, if you don't like a lot of induction noise, don't run a muffler replacement pipe and Growler combo. The Growler with inlet muffler installed however was fine.

Cheers, Bomber.

Is there much cold air behind the drivers side headlight?

I would have thought running an under battery pipe + remove the foggie would be better?

Put the OEM pipe back on today, to be honest it's so much nicer to drive the car now, car drives the same but is so quiet under light throttle. Much easier to live with now.

Has made me want new rear mufflers to shut the car up.

I've fitted the Rapid turbo intake pipe last night, and to be honest the difference in spool sound is minimal.

... My car is stock at the moment, so perhaps that's why its not very noticeable?

On another note, I noticed that my BOV (which I have vent to atmo) is pushing air out at idle....WTF ??? I think I am going to block it off as suggested by Dillz.

It doesn't do much without a pod but makes a hell of a difference with one.

So if you wanted MAX turbo flutter, a battery relocation and turbo side pod would give you the loudest? Just trying to get a clear picture,.. cheers

Yep. In particular a stainless kit (if you have an fg!! No b series afaik)

Contact stainonegger on here as he makes them. Gives the whole lot, pipe, pod, air box to enclose it and battery relocation

Yep for the loudest you need the battery moved, then you can do whatever intake you like. If you want long? Highoitched dose a short bend and pod is the go. With a 4" intake it's a long deep slow flutter.

anyone run a turbo side intake with out a tune? wanna move mine to get rid of the crossover but not keen on a tune
