a few weeks ago i put the super six setup on my valiant. what a difference then i did something i have been thinking alot about, ram air.
what i did was pull the air snorkel adapter, flex hose, and plastic intake tube from inside the fender well, from an 85 new yorker. there is a cap on the end of the tube behind the bumper, grab that. i didnt use the plastic intake tube on my application but you might. the little cap has a cover over it spaced out about a half an inch, take that off. you will need to use a hole saw and cut a 3 1/2" hole in the radiator support, i went right next to the radiator centered in the grill opening. i came off the snorkel adapter with the flex hose directly to the little cap that is fitted into the hole in the radiator support next to the radiator.
this has the appearance of (half) a ford thunderbolt. it looks all factory, even has chrysler part numbers. it all fits under the hood and is unseen. and best of all.......it works great
the difference was amazing about the same as putting the BBD on a few weeks earlier(really!!). around town the cold air helps but on the highway, its incredible!! i used to have to pay attention to keep up 70mph, now it cruises at 80, with plenty of pull left in it
i cant put any pictures up here, but if you PM me i can send you some. if your coming to MATS next week you can look at it in my white 71 valiant

Hi powerwagonpaul. The setup you describe was stock on the f-bodies with the super six. If you use your car in a colder climate, you should try to find an air filter housing for an Aspen/Volare with the BBD. Then you can have the advantage of feeding heated air to the air filter through a smaller flex hose from a mount on the exhaust pipe. That will prevent carburetor icing when the air is too cold, by routing vacum to a flap in the snorkel via a temp feeler in the housing to let in the heated air. In general, a cold air intake gives app. 1 hp increase per 7 degree F temperature drop, so it is absolutely something you can feel. Good work!

BTW, very nice air intake ducts can be found in shops that supply parts for making your own bass reflex speakers for your stereo. The sound outlet ducts, called port tubes, make attachment of a flex hose much easier, and look very nice too. They can be found in lots of sizes, see this or this link for some examples, there are lots of suppliers out there when you know what to look for. I think I'll make a separate thread of this last piece of info, others may have use for it too!

olaf,
that setup on the aspen, from what i saw, it pulls cold air from behind the fender, not a high pressure zone i wanted to pull cold air from a high pressure zone outside the engine bay. i know that the 69 charger 500 had the grill moved forward, flush with the hood to prevent high pressure air from building up in that opening. looking at the grill on my 71 valiant and a friends 69 charger i saw a similarity, its a big 'ole air grabbing box! i figured to take advantage of that. i don't really know if i am getting any real air pressure to the plenum, but i figure at least i am getting the highest volume possible of cold air. seems to work nicely
that little cap i described has a nice bell shape to it just like those bass tubes. those would be good for other size air ducts (thumbs up smiley inserted here)
dan offered to post my pictures. it looks real clean.

Hi again powerwagonpaul. You are abolutely right about the high pressure zones.

I know nothing about your bakground, so this little tip may be total overkill if it is something you use all the time, but here goes:
When the Dodge Aspen Kit Car was deviced, the Mopar guys did some additional research about where the air intakes should be placed. The highest pressure zone they found, and also worth noting - farthest away from road dust and least influenced from wind direction in curves- is actually low on the windshield. That resulted in a rearward facing hood scoop. It is also the reason your open ventilation outlets blow like h.... without use of the fan when you open a side window. You can easy check where the highest pressure is by clear plastic tubing, long enough to be twice the distance from inside your car to a measuring point, for example the grill. Fix the middle of the tube as a U on a board inside the car. Fill a little colored water in the U a couple of inches high. I don't know what it is called in english, but I use the kind of color that pastry bakers use to color their marzipan cakes, it easily mixes with water. See to that the board is held in a fixed position, and mark the board at both sides of the U at the water level. Then you can draw the tube ends out a side window, to different places where you want to measure the pressure DIFFERENCE between the measuring points, i.e. one to the grill and one to the windshield. Just fix the hose with tape, with opening facing forward but lifted up a little from any flat surface, or else you risk getting a false reading. Take a little ride, and watch the difference in water level height on either side of the U tell where the pressure is high/low. You can also draw the hose ends to the same place, but one end facing forward and one facing backwards, that way you can eliminate influence from wind to get a real presssure high/low point. You're about to get some real surprising results; air never really moves as you think it should! :shrug:
You should also take a look at AggressiveTed's site.
I look forward to your pictures! (jeez, I have to stop using these emoticons! )

It's certainly a nice clean installation, but there are a few things I wouldn't like about it on my own car:

1. Can't drive in the rain or snow without sucking up a bunch of water, which will fly right thru the grill and into the unshielded air intake. This is why factory ducted air intake setups have their inlets where they do!

2. Unducted crankcase breather

3. K&N air filters are a scam. They do an okeh job keeping spiders out of the intake tract, but that's about all. Dust flies right thru.

4. Sometimes ram air setups used with carburetors not specifically calibrated for them can cause weird driveability faults.

Dan,
thanks for the complement, as far as the downsides....
1 your right about driving in the rain. but i live in las vegas, we get about a dozen rainy days a year here. i would rather drive the truck anyways. and that other thing.....snow? not real familiar with that but i'm sure your right
2 but its chrome!!
3 i know most the desert racers use K&N, i figured it would be good in the desert
4 it does still need some fine tuning. at about 30mph it has a slight stumble on mild acceleration. i think it is not making a smooth transition to the main circuit without the pump. that and it seems a bit rich. that i think is because i have the choke removed and i need to jet down because of the increased vacuum signal to the venturis. could all be the same thing. ill get it right. overall i would rate it at about 95%, not bad for "out of the box"
thanks for your input guys and keep it coming. if your in vegas for MATS it will be in the popular choice section, come by and give a slanty a vote!!

...and rebuild their engines every season. You live someplace dusty, like the desert? Use a real air filter. See here for a thorough comparison test of air filter filtration performance.
Sounds very familiar to me. See here and here. As an experiment, try disconnecting the flex duct at the air cleaner snorkel, and turning the snorkel so it points across the valve cover. Go drive the car and see if that stumble goes away.

i was under the impression desert racers use oil bath air cleaners
