where to run the cold air intake???

[Daniel.B]

I want to fit a CAI, preferably this weekend, but short of fabricating something myself, are there any really good bolt on options available. Yes i've searched forums, and ebay, and i've rang people. So far, all i've come up with is a place in sydney called "Thongy's" where i can purchase what is said to be- a genuine Holden CAI for VN-VS, It appears to be 2 peice over the radiator system. What are the pros and cons to over the radiator as compared to under/ around the bumper area? What sort of piping is most commonly used if you were to fabricate your own system to run under the bumper. Also one last thing, i've seen on a few occasion, people use a material which looks similar to that used to wrap turbo's to help keep them cool, wrapping this stuff around their induction piping- are there any real world benifits to this , or is this more suited to extreme cases .

the turbo heat wrap is in extreme heat cases, and not necessary for just a na cai.

theres a how-to in the how-to section on a 'two hole mod' for installing a second pipe under the bumper.

Go the standard CAI, they're perfect, and only requires cutting a little out of the air box.

 

[Daniel.B]

what do you mean by the standard CAI's, are these the genuine items that are advertised on EBAY?

Yep thats what he means, with the mouth that opens up over the radiator. Unless your prepared to get the sheet metal and mig welder out, they are far and away one of the better and cheaper/easier options.

Next question?

Daniel.B you buy the factory one at your local Holden spare parts of course and yes the guys on ebay buy them from Holden and resell them. it is not as good as a pipe to the bumper but it's OK. You want the VS V6 supercharged version

I'm happy to run a pipe down into the front bar, but i'm not sure on what sort of hose/piping to buy? it would obviously have to be quite flexible, but i dont know if i have to buy this from some type of auto outlet, or whether i can just pick up something from bunnings and go at it with a hacksaw ect-

Airstrike used to work at bunnings and I think they sell alot of "intake pipe" there all you need is some flexible plastic or rubber pipes that wont colapse under strong suction in about 100mm diameter

 

[Daniel.B]

yes i just can't find out where everyone get's these sections of pipe from-

 

[Daniel.B]

when i find out, i'll go out and buy some, have a go and making my own CAI, post some pics, and should be all good for a laugh-

I got re enforced rubber duct (steel inside) from a engineering shop but it's expensive. Plastic flexy pipe will do the job
