im not really sure what's the best CAI set up for the fto. From what ive read the main ones are ARC and UAS, thoughts from people who have either? or if anyone can mention others worth checking out. (really looking for something with piping to throttle body, pod/filter and case/enclousure for pod)
im also wondering what is the best way to re route the stock intake set up, ive seen a few different DIY's but they all vary abit.
eg: http://www.completefto.com.au/CompleteFTO.asp?aid=318
This doesn't seem all that effective because it's taking air coming in front on and trying to pass it into a pipe that's perpendicular to the incoming air (hello turbulence)
to me something like this (below) looks to be the ideal set up because the piping connects directly to the pod/filter getting the cold air directly to the pod and not having some of it lost in the engine bay as would occur with a normal pod set up (even if it was enclosed)
does anyone know if the above set up is sold, or is that custom?
You have to take into account the fact that the air being fed from the front at any reasonable speed will be pressurised if you make the intake on the front bar larger than the pipe. If you set it up this way, a little bit being lost from the enclosure wont make that much difference. The issue with the setup you see there is that it is right next to the hot engine. Unless its very well insulated (which I bet it isnt), it will be getting quite hot!. Note the pipes certainly arent insulated. The box I built is fully insulated. I chucked a temp guage inside and outside the box. Was getting 70 degrees outside the box and 31 degrees inside the box and the outside temp was in the high 20's). The UAS intake pipe is good because it is thick rubber and does not easily conduct heat. Admittedly, the bends will interrupt the air flow somewhat and certainly should be minimised where possible, but I believe the heat has a much greater effect. All you have to do is compare how well your FTO performs with nice cold air in winter vs the hot air it gets in summer. I always look forward to the winter days....
Yeah, those CDA filters are quite pricey from memory, although they do have an Aus distributor if you had your heart set on them: http://www.bmcairfilters.com/infoCDA.asp
Like DStocks said, the UAS one is good for a few reasons. Nice thick pipe with few bends. Boxed (not very well sealed, but can be done easily). But best of all, it just bolts on without too much faffing around.
But plenty of other DIY's and been done. Toolboxes, plastic containers, foil windscreen sunscreens, etc have all been used as a box and hooked up with custom piping.
If you can't dazzle them with dexterity, baffle them with bull...

wow thats quite a difference in temperatures in the engine bay and enclosure. any chance of a pic of the enclosure you have? im guessing it's custom?
have you got any UAS intakes lying around dstocks? if so what price would i be looking at?
Grue: yeah was not really set on that pod, didn't even think about how hot it would get being so close to the engine. it does look pretty sweet though.
At a recent dyno day, Aza's fto got an extra 8 - 10kw at the wheels with the UAS pipe compared to the stock sized one. It goes to show how big of a difference can be made.
