it should not be a problem sense we are just going to make alum ones to replace the oem plactic ones

Ya these cars come with hood vents, so there's plenty of places for the air to go once it comes through the IC and/or radiator.

My bad, didn't know they came with plastic ones.

Heh I was going to call discount steel for a quote, but guess what, their stuff is available online!

I need advice, they have 5052 aluminum sheet:

or 6061 aluminum:
http://www.discountsteel.com/index.cfm/go/main.itemDisplay/itemID/84.htm

I did some measuring:

and I figured out that I need about a 63" x 38" sheet.

The above links will give me a price, but the size is listed in .032-.190, is this supposed to be like .032 inches, or is it a gauge or some sort? .125 in the dimensions I want is going to be like $90 for a single sheet of the 5052, doesn't this seem a little expensive? I don't mind spending this much, just want to be sure I'm getting the right thing.

The site says they also offer precision cutting, I might hit them up and see how much that'd be....would be a nice way to reproduce this for other evo owners....

.032 is 1/32 in
.125 is 1/8 in
.190 is 3/16 in

6061 is aircraft grade alum.
alum is not that cheap to start with. could always go with steel and have them power coated

Overheating probably wouldn't be an issue, but it wouldn't be hard to make some louvers in it to pull some heat out the bottom. As far as using some type of plastic goes, I'm not sure if that would be such a good idea. You have to remember that the down pipe would be right next to it, and of the ones that Jet listed there, the highest max temperature rating was only 210*. Also, the one that listed an impact rating was only 1.3 pounds. As far as template material, I would suggest cardboard. I can get pieces more than big enough from my shop from the boxes we get parts in. To me, tag board would be a little too flimsy to work with.

We sell those 1/4 turn bolts at my volkswagen dealership (they go in passat bellypans and they dont have the little handles) and we sell those speed nuts too. so i guess if you need a replacement or somthing you know where to get them without waiting.

1/8" aluminum is going to be pretty flimsy on a piece that big. I would look at the 3/16". I really love the UHMW, it takes a serious beating. Aluminum will work well too and be slightly lighter, but will dent.

This is really ghey.

To get a sheet of aluminum the size I need, the metal alone is going to cost me $180+ and if I screw it up, too bad (sorta).

To get a thinner sheet of stainless steel (heavier, but stronger), I would go with like a 12ga (1/10") sheet.....~$300 :(

Anyone have any other ideas? Otherwise, if the price is right, Buschur is selling a pre-cut, pre-measured undertray for $175+shipping, no muss no fuss.

Also, looks like I can get regular steel for $70, but doing the math, it's going to weigh 60 pounds! Geebuz....
