Vxr8 cold air intake..........
Discussion
I got it from Aus, company called Original parts group, as for running over......... anyway as you said, looks nice and gets rid of all that black plastic hiding the front of the engine.........plus it sounds cool........will try it out on the french motorways later this week..........

Yeah this is worth a read if you are considering one..
Note that the designs are all similar, being over the radiator. For best cold air induction I think you will find that design best. Though some require you to remove the MAF. The VXR8 map is very close to perfect running off the calculated airflow values, so the loss of the MAF doesnt cause any issues. (If you have the right software)

Stationary/Slow I think mine was 10-12* over ambient.. I need to check properly.
I have the Russo one as below

any idea which ones of these will fit a 07 monaro vxr?
That's a VZ and this one says it does http://cgi.ebay.com.au/VY-VZ-LS1-LS2-Holden-Commod...any idea which ones of these will fit a 07 monaro vxr?

You will have to have a MAFless tune to run that one too.
theres this thingy called a MAF in the intake pipe running from the airbox to the front of the throttle body, inside it has a fine mesh and some electronics that communicate with the cars computer to help it work out how the car engine should be fed with air and fuel to run at its best. If you remove it then you have to tell the computer to use a fixed set of values from a table. Get it right and you can see performance gains, get it wrong and the car will run like a dog. Its quite a common method of running in Oz and theres a fair few of us over here running mafless. Most common reason for doing it though is because you're running an OTRCAI (over the radiator cold air intake) which pushes a lot more air into the engine than the standard intake but doesnt leave enough space to fit a MAF. Thats the dummy's guide, I'll leave it to others to give a more technical description
Edit: look at first picture at top of this thread, follow the shiny chrome pipe towards the top of the picture until you reach the round black object with wires coming out it - thats the MAF in that car. should be in almost exactly the same spot on your monaro.

Whats Mafless? Please
An engine without one of these....http://en.wikipedia.org/wiki/Mass_flow_sensor
Holdens have both methods stock, the other one is http://en.wikipedia.org/wiki/MAP_sensor
Basically the MAP is used to sanity check the MAF in our cars, plus for transient conditions and other times. Ive not seen a definitive statement about exactly when the MAP is used I think it depends on the vehicle and calibration.
But yes, you can easily remove the MAF and get better throttle response, but the tune is harder to get right as MAF based fueling is somewhat more staight forward with only a single column of values which relate directly to airmass. Speeddensity/Mafless needs an accurate map of the engines efficiency which runs to hundreds of values and in some cases thousands. However in order to do a proper full tune both methods should be dialed in 100% This can take a long time on a new setup. Id hate to know how long the OEM's spend on their tunes.
Over 2 million late model EFI Hemi engines run without a MAF FWIW.

I think i understand a bit more than i did
Going to read up on it in detail when i'm back at home and not in an internet cafe. Rich's does'nt have that large chrome pipe leading to th maff it just has a large air intake above the rad. Is that right? Are Chipmaster available over here. Like i say when i have a few hours i'll google all this. Cols getting ratty as i'm spending a lot of my holiday learning about V8 engins. Then going back to him and telling him what i've learned. His response is usually "get us a beer bab". Then i dissapear under the bonnet of the ro
for a while till he needs another one.

A nice straight forward explanation of the 3 main fueling methods here
