Need to know what size CAI pipe people are running.

Making a fully enclose POD Filter Box and want to make the mould as flexible for various intake sizes as possible.

Thanks for the feedback!!

100mm to standard airbox. I used to love the sound of my pod on the 3l TE. Oh well.

90mm... I have just bought some parts as I intend to run 90mm piping down from a boxed pod to a cold air source... saying all this i am still very interested in your project.

who was it that cut a hole in he's front bumper for his Air intake ( M3 style )

seriously considering it, its the best place to get cold air from. the faster you go the more air goes in aswell.

I'm running 90mm PVC.. but I'm also still running a panel.

Any chance you want to make up a box that'll fit a standard panel filter? I'd probably switch over if you did because it's a PITA to mould the PVC to the oval opening of the standard air box and I'd rather not hack it up to make a round hole in case I need to re-fit it for warranty or something.

It's been on my mind a lot actually. It will be a wait away thou. Got 2nd Gens and V6 Commodores to do. I know, I'm a ***** :cry:

I've got 80mm which is the biggest i could go with the battery in the same position on a 2nd gen.

I have 75mm flexible air duct, goes down to an 80mm pressure PVC fitting, which attaches to a 90mm stomwater 75mmx100mm downpipe fitting and fits neatly in to a fog lamp cover. I had to heat the downpipe fitting in the oven in order to get it to fit the 80mm bend.

If I were to construct out of PVC (which I intend to do shortly) I'd choose 80mm pressure pipe over the 90mm (or 75mm) stormwater - pressure pipe has thicker walls and is more heat resistant. Expensive though.

80mm.

Biggest i could find and it was a bastard getting it in because of the battery and the only place i could put it in was in that hole near the battery.

Its going to suck when i need to change one of my head light globes.

Nice Avatar! I have an SF2 Champ Edition Arcade Machine in my Shed!! Cost me $200 like 7years ago. Figured I'd put twice that into it at my local takeaway store.

Sorry but that's wrong. The higher up the inlet, the cooler the air will be. This is becuse of heat from the road. In tests the manufacturers have done, the temp difference at the top of the grill and at the bottom of the bumper is quite large. That's why most manufacturer's CAI's are placed in the gap between the radiator and the bonnet. If you want the 'ram air' effect you can still achieve this by using a scoop.
