increasing air flow to filter

[kingearl]

I have a couple ideas and I was wondering if there would be any problems with them.

First, what are the metal bracket pieces behind the headlights for? Are they to help support the hood or something? I wanted to cut bigger holes out behind the headlight so more air would get to the filter. Good idea, bad idea?

And, I was thinking of putting a scoop in the hood just behind the headlight to force cool air to the filter. The prob is I dont really get how they work, do they even block out rain and snow? And if they do then how do they? If they dont then I guess its not a good idea to put one in.

I came up with a pretty decent (cheap) solution:
I cut the whole front off my stock aircan, built a sheetmetal airbox betweeen it and the headlight holes, cut the inboard headlight hole bigger, and used a 2.5" duct to bring more cool air to my K&N filter.
I'll add it to the VFAQ as soon as I get the rest of my pics developed. Here's one of the airbox without the top piece. (92 TSi AWD w/ ABS)

Guys - Help! my pic won't attach. What am I doing wrong?

I got a carbon fiber scoop from carbontrix.com. works great

the bracket is for 90-91's. it holds the pop ups.
easy way to block water out of a scoop is to cut a magnetic sheet the right size, just slap it on when it rains or pull it off to race.

hmm, so you have to find a way to cover scoops and vents from rain. That sucks.
Thanks for the hints. I'll work something out.

I ran dryer duct from under my car to the K&N and it worked ok. Was barely visable. till I went camping! It got ripped off.

Got ripped off by people or the ground?

I was thinking about that but not sure how effective it would be.

Its a little off topic but, by getting an AFC what would you be able to cut off the MAS to make it flow more air? Could you cut off the whole top end? I am talking about the 1g MAS.

on my car now i cut out the metal to the left of the KN filter.... (looking from the front)

i'm talking about where the Upper IC pipe goes through, i cut out upto the headlight and back to the wheel well.

in Stock form with just a KN, the logger was showing my air intake around 105 and after boosting the turbo it shot to 138 and would not come back down.

after i cut out the metal and put a piece of metal dryer vent. my air intake temp dropped to about 83 degrees and while under boost the temps actually dropped or held steady. the temps have never went above 5 degrees above outside air temp....

another way i thought of was to weld a 3" pipe off the end of the stock air can, and fit the pipe down into the wheel well

WHAT?! Thats nuts! I'm guessing you dont have any pics of this? Could you explain better so i could do this. There is now a HUGE hole from where the upper IC starts to the back of the headlight? Thats safe to do? The air just rushes throu there and hits the filter? How does your air box work?
