Cold air box design?

[Gly]

ok so after a bit of slacking off i moved the battery in my legnum to the boot,

now comes the fun bit... making the cold air box...

so my idea is to make the box of stainless steal.
and will be bolted to the factory hole that originally held the battery tray.

the AFM will be bolted to the box,

the pipe from the intake manifold to the afm will be S/S also.

ill use silicone joiners on the pipe/afm/intake.

but heres where i have to make a choice.

since everything is bolted to a fixed pos, and the engine sits on mounts which do move a bit?
will the engine move enough to maybe break the silicone joiners or maybe shove the S/S pipe thru the afm, or bend my box? (hehe)

will silicone joiners used for intercoolers be ok, or do i need something with a bit more flex??

i can get silicone joiners with a bluge in the center which can compress and strech a bit... would this be the best option?


rough pic,

blue is the silicone joiners... the bulge type is down by the afm,
black is the AFM,
green is the pod filter,
yellow is the ss tube,
red is the ss box.

what do you think??

I think you might have a fair bit of movement front|back (looking from the front) because of the engine orientation. start the car, get under the hood and then snap the throttle open and closed to see just how much movement there is.

In my old 1.8 GDI, there was a fair bit, haven't really checked out the VR-4

If you were to use the stock elbow from the AFM to the throttle body, I think you should be able to absorb all of the movement. You could always do something with the engine mounts to stiffen it up as well.

you wont have any trouble with movement.

where is the cold air coming from?

heres pics from my one. maybe of some help.

please dont use PVC piping for yours, i only had that in for one day as i was working out how to plumb in the filter.

dont really wanna use the stock elbow, its FUGLY!!!
need shiny bits :happy:

im gonna check out how much movement there is tomorrow,
hopefully not to much.

im gonna be taking air in from the front of the car.

ive worked out i have enough space to cut a 3" hole next to the inside of my spotlight,
and have plenty of room to duct it up to the underside of the cold air box,

cheers for the pic's,
dont really wanna cut up my bonnet at this stage.

NO PVC.
Stainless Steal,
probabilly card board to make a proto type :thumbsup:
