Ok i'm going to post this as it is the cheapest mod and one that is asked about a fair bit.
Ok this only applies to Series 2 VN's thru to the VR.
Firstly the bellmouth was fitted to improve air distrabution to the rear cylinders providing an even air:fuel mixture for the whole engine, giving a smoother idle.
So from what I just said there is a chance that the idle may not be as smooth as previously but hey, when are the Buick 6's ever smooth ;)
Now I'm not promossing any increase in power but, you will find you will have an increase in throttle response.
I have included a picture to show the location of the bellmouth and will write up some step-by-step instructions on it's removal abit later.
Cheers AirStrike (Dave)

It's said that if you get a CAI (Cold Air Intake) after taking out the bellmouth. The engine will idle pretty much normally.
Without a CAI it is said the engine will idle rougher.
I can vouch for the engine being rough without a CAI and Bellmouth.

Not Smooth ?

Just a quick 1 .. every1 in here says that buick v6's arent "smooth".. LOL i disagree totaly, i have never driven a car with a smoother / more powerful & echanomical motor than a good ol commodore. Maybe you all need volvo's !! smooth as a baby's bum

it was fitted to improve idle quality & will not decrease power or throttle response, any improvements noticed may just be wishful thinking
As it happens i was in Holden experimental at the time this was done so i have seen first hand the effect on the engine.
