Cold air screens
Just read the instructions on installing them. Whew! Anyone just drill holes in the fog light covers while it was still on the car? How do you clean out the left over plastic bits after drilling? Any downsides to this? Thanks.

Re: Cold air screens (NoRice4Me)
Several have done this with the same effect as the store-bought bits but with much less hassle. They used a hole saw and a drill to cut the holes. Someone even has a template for the hole pattern.
I can get my arm in behind there with the hood up and reaching behind the fascia so you should be able to clean it out fairly well. :cheers:

Re: Cold air screens (jmcassin)
Also, the folks that have done this, how much dirtier does the engine compartment get? Do you start finding leaves and dead bugs all over the place? :smash: Or have you all put in Z06 screens?

Re: Cold air screens (NoRice4Me)
I have the Z06 screens with the stock fog light surrounds completely removed. My engine bay stays justs about as clean as before. :cheers:

Re: Cold air screens (NoRice4Me)
Was thinking of cutting holes to. Seems the screens are a pain to put in. I wonder if anyone that has done this could tell how many holes they cut and if the dynoed after or noticed a SOTP difference

Re: Cold air screens (NoRice4Me)
man, i just put these in last weekend and what a pain in the butt! now i
know why the previous forum owner sold them! it's a real question
whether it's worth the hassle versus just drilling holes. i will say that
once they're in, they look great, very professional. but i'm not kidding
when i say that my forearms are still scratched up today (wednesday)
from the installation last saturday. the instructions don't even come
close in describing how tough this is or add'l steps necessary to facilitate
the install.
anyone need help in installing these can call me first and i'll give you a
few tips to make it a little easier.

Re: Cold air screens (NoRice4Me)
Why dont you use a small hole saw on a power hand drill, like 3/4" and drill out holes that way. Hole saws don't leave much mess behind the hole. Run a vacuum hose while your drilling to suck up the little bits. :cheers:

Re: Cold air screens (NoRice4Me)
The heat from the drill bit will melt the plastic around the hole and leave a rough cut. Even with them out, and with a Dremel, you could spend a couple hours really cleaning / smoothing it all up. No way to do that in the car and the risk of scratches would not be worth it.

Re: Cold air screens (NoRice4Me)
I took my fog light surround panels out ( four bolts.. if you know where they are it isnt hard.. you have to take the seven or eight bolts out from under the car .. right in the center of your front facia.. you can then reach in and get the four screws.. ) I then dremeled out the obvious area leaving the fog mounts section intact... I cut out a section about 3 inches by 6 inches.... then I bought one section of gutter screen at home depot.. cost was 3 dollars... ( enough for both sides ) I epoxied the molded screen to the back of the surround pannel ..masked off and painted them satin black.. you are not going to notice any difference but im sure there is a positive effect.. it does help with engine cooling too.. they look better to me .. than the screens.. I like that black scoopie look on both sides and now they are functional...

Re: Cold air screens (Evil-Twin)
Bill, You know several have tried to make the Z06 front or "Gill" screens from old air filters. But other posts have questioned the durability of that material.
The other day I saw some "gutter guards" in Home Depot and thought that material could be ideal for the "Z06 screen" look. What do you think?
I also thought about painting them black for my Gill Screens as my color sceme is Dark Red and Black. Only the wheels and rotors are chrome.

Re: Cold air screens (QuickSilver97)
Whew, seems like an awful lot of trouble for a few holes by the foglights. Biggest question I have is, is it worth it?
The Blackwing works on the principle of having a gigantic surface area, therefore very low resistance to the intake of air. It's drawing from the whole area of enclosed air north of the radiator shroud. That's inherently a non-constricting relationship, since you've got a large air cavity feeding a large filter surface, feeding the smaller diameter MAF. As long as fresh air ingress to the air cavity is equal to or greater than the flow of air being pulled out, the relationships remain. There is adequate space around the bottom of the intake air cavity to easily replenish it (much larger total intake area than the MAF diameter).
So I don't see it as a big advantage. It's not going to be enough to create a ram air effect (for that, the volume of air into the forward intake cavity would have be sufficient to create an overpressure effect, and that would seem to require a larger intake area than the foglight shrouds can supply.)
If anyone knows of a good reason to do it, other than looks :) I still might try it, but I really think it's probably not going to boost performance.

Re: Cold air screens (gnosys)
Well after working with lexan/plexiglass, I know that drilling nice and slow will save a lot of cleanup effort later on. Going about 1/8 speed with a 12v drill should leave the holes nice and smooth. It takes longer to make the holes, but you do save time in the end.
The main reason I want to do this is my butt dyno tells me I've lost some high-end power after adding the hood seal. The cars is just not as responsive and doesn't pull as hard in the upper rpms. I used to lose traction in the rear wheels at WOT at the end of 1st, but not after the hood seal was added. I need the seal since I noticed the K&N getting wet from the cut intake cover after some rain or a car wash.
I figure a few holes in the fog covers should let the cool air back in and restore the cool air lost from the hood seal. Anyone else experience this?
