As for the Halltech air filter sitting above the plenum , there wont be much improvement ; the air filter needs to be in a sealed box who's bottom side is cut into the plenum -- in fact since i work with sheetmetal all the time in my trade, im going to make a sheetmetal box for the Halltech to go in then tap into the plenum for 100 percent cold outside air. Ill paint the sheetmetal box flat black so it looks nice and make it easy to remove for when i need to get to the filter. Question : Can you please tell me the approx. dimensions of the Halltech filter so i can get started before it arrives ? Is it larger than the Blackwing filter ?? Thanks much. Dave
This is the stock lower shroud that is behind the grille with the "Halltech" mod. This modified part will bring colder air into the area of the air filter

Yes, you can do this mod yourself. (I bought one of the first batch myself). The vette guy at my local body shop threw it on in less than 5 minutes.
Yes, it does make intake air temps = outside temps.
Yes, (unlike others opinions) it does get the engine compartment dustier (but I live by the beach and there's alot of blowing sand), but NO it doesn't risk water in the intake (unlike the bottom feeders). It is probably the safest way to get outside air temps at the intake.
There is no "proven" "RAM AIR EFFECT" for any of the other "supposed" RAM Air intakes. The increased flow numbers come from the better filter, not from any additional "forced induction" (which is what RAM Air implies). You're not "ramming" any more air into the motor, even at speed. Want more air? Get a BLOWER and a closed loop system.

Anyway, your findings is very encouraging ; this means i wont need to fabricate a box for the Hallteck filter to sit in and cut into the top of the plenum panel. Looking thru each hole on the sides from the bumper, it appears that most of the ram air might go underneath the car, therefore, im considering making a couple of small metal defectors on a 45 degree angle , or, a small 90 degree elbow ... so the ram air hits them and is directed more upward.
Ive also considered drilling two 1" dia holes directly under the Halltech filter in the top of the plenum which would have a bit of ram air hit the filter directly --- but perhaps this isnt necessary now since the air filter is the same temp as outside.
Thanks for your temp feedback. Very encouraging indeed.

sickrick, you local guys put it on in less then 5 minutes? i have to take out the brake ducts....ect and it took me alotttt longer then 5 minutes, i am embarrassed to even say.

. DId you fab 'sheetmetal' panels to direct the ram air upwards more ; im going to measure up and make some panels out of sheetmetal , prime, then paint them satin black to blend in. IM going to go from the floor about half way up the radiator at the same angle as the radiator is sitting -- that should turn the air upward pretty good . Ill place my remote temp sensor near the firewall at the back of the motor to see what sort of temps im running after i get it installed.

Guys I'm sure GM engineered the car so a certain amount of air is forced to flow through the radiator. Anything you do to make it easier for air to go around rather than through, it will. I know it's winter now and the air is cool, but radiator temps may be a factor on hot days, especially for you guys who track your cars. Just a thought, but unfortunately I suffered the consequences of similar modification on my twin-turbo RX7 (however those cars tend to run hot very easily, especially with mods). I'm just saying I would keep my eye on it.

i original did the "davidfarmer" method, which is cut 2 holes the size of the stock panel filters on the radiator shoud, and swapped the filters and turn them up side down to "steal air from the radiator / condenser". it really kept the under hood temp down with these 2 giant 8x9 inch holes...but i couldn't get a good seal for the air filters. (davidfamer has posted some pictures of his after he got them to seal) i am ok stealing air from radiator for the air filter but didn't want to "steal" to cool the under hood temp considering where i live....
so dave, you testing shows without some type of panel to direct the air to go up, the temp by the filter and outside is still the same? is that is the case i wouldn't go through the trouble "fabricating"....no, i didn't use sheet metal...i was afraid it would have sharp edges that would cut me if i wasn't paying attention while "monkeying around" in that area....so, i end up using some plexiglass instead. my panels goes all the way up to that plastic cover that covers the radiatior...actually, it goes just under that cover to help secure the panels. any one know how i can post some pictures? i will rerun these temp test data this summer when it get over 100 degrees and see what happens.

The reason for me using upward deflectors for the side openings is to get as much ram air going over the motor instead of loosing some to the ground. Im just going to follow the slant of the radiator outside edge.
Why dont you send me some of your pics to : Fast1970vette@webtv.net of this and any other mod you may have done. Always interested in seeing what others have done. Thanks. Dave

Great info here. Downloading the instructions didn't do a lot for me. Reading through the posts here helped me to understand the installation and was able to finish just based on that. Took about an hour and a half.
Thanks!
Thanks!
