As requested by lv360ram. This was a kit I won off off ofebay. It was intended for use on a camaro. Box is the same as the Ram kit. I did have to buy a flat cover. I adapted the snorkels a bit to make them work. I haven't fully testedit yet, but so far I have found that, at highway speeds, iat sits around 5* warmer than ambient temperature. This is with the iat sensor installed in the M1's designed location. At 70-75 mph, I picked up 1- 1.3 inches of vacuum. This allaccording to the Equus scanner.Only problem with the install was sealing it. I had to buy two different kinds of weather stripping. I don't know if the original kit comes with a means to seal the whole thing up or not, but,if it doesn't, it should.

Wow! that is a beautiful thing![sm=happy046.gif]
Are the clamps that connect the tubes to the air box sewer pipe clamps?
Where did you get the black ducts that are bolted on either side of the radiator?
Thanks!

 

Affirmative, 4" stainless and rubber no hub pipe couplings. The snorkels came with the kit. I plan on fabbing up some better ones down the road to play around with the whole vacuum signalthing.

 

i would think it would be much more effective if you didnt use those black ducts.

 

I used the snorkels for two reasons. One, the primary reason, because there is not 4" of space between the radiator and the upright to run the 4" duct without mashing it down. Two because I wanted a secure anchor point where I didn't have to worry about the ducts gettng blown back into the belt. I read afew write-ups on semi-home brewram air intakes where guys went way past where I will ever go in testing this set up. The predominant theme in allwas that the main thing is diameter of the duct, the angle of the duct opening to the road surface, and the total degree of bends in the duct determine the effectiveness.Snorkels make no difference one way or the other. Everything I read was pretty much against them because they would add cost to the setup.

 

that is a nice set up. one thing, will it prevent rain/snow from getting to the filter an intake or will it just evaporate before getting there?

 

Thanks.I was using a Volant setup with the air ram and had no real issues w/ rain. As far as snow, I plan on running the Edelbrock foam filter like the one below in the cooler months. BTW, though it will have no potential for the ram effect,that filter flows better than the 14x3 round I am using now. The K&N 14x3 flows a little over 791 cfm. The Edelbrock flows 1000 cfm. A 52mm tb flows around 972 cfm (50mm flows 866). The potential exists for a bottleneck, though with my setup I doubt one really exists. For anyone interested, according to K&N, their filter media flows 6 cfm/sq in. as measured on the outer surface.

Those are some good flows. How often while driving [sm=gears.gif]isyour intake flowing over 600cfm? Only at the racetrack?[sm=burnout.gif]

 

I am often falsely accused of 'hating' all air intakes
but the Ram Air box above is perhaps the most
likely to give dragstrip gains.
My only reservation is cost.
Owners who want to economize with a similar design
could modify the factory round air filter used on
Magnum V8s in early 1990's Dodge full size vans.

Check out the 2006 BMW M5 air intake for a 'ram air' design on a vehicle that
can reach 'only' 190+ mph. Note that the BMW engineers NEVER claim this intake
improves MPG, even though they list dozens of other engine features on the 5L
V10 that do improve MPG.

also the similar Infiniti design:

old post on the science
===
Heard of the 'Ram Air' effect where the speed of the air hitting the vehicle
builds up pressure in a forward facing air duct and helps 'supercharge' your
engine a bit. ?

Well, at 'typical' street speeds the effect is very very small.

The formula for that is:

Inches of water pressure from Ram Air = (mph) times (mph) divided by 2025.

So at 70 mph the ram air effect is:
(70 mph) times (70 mph) divided by 2025 = 2.4 inches of water.

So the very best possible air inlet tube designed for Ram Air would actually
have a positive pressure of 2.4 inches of water.

How much pressure is an inch of water ?

One psi of pressure is equal to about 28 inches of water.

You can get this by dividing the cubic inches in one cubic foot ( 12 x 12 x
12 ) by the weight of one cubic foot of water ( 62.4 lbs).

The air pressure around us is averages about 14.5 psi at typical heights above
sea level.

So another way of looking at it is that the air pressure around us is about
400 inches of water. ( 14.5 x 28).

So the best Ram Air system at 70 mph gives you a boost of about 2/400 or one
half of one percent. Small.

Ram air started in airplanes where it means more. An airplane going 300 mph
gets a boost of:

300 x 300 divided by 2025 = 44 inches

This is a percentage boost of 44/400 or about 11%

Want a challenge?
Consider your tires.
Some strange facts:
At 70 mph the center of your tire is moving 70 mph.
The bottom of your tire where it 'grabs' the pavement is moving at 0.1 mph
The top of your tire is moving forward at 140 mph.
If you could put a 'Ram Air' inlet right at the top of the tires (where it is
horribly dirty and wet) you could get a significant air pressure boost.....

 

i spent just around 80.00 bucks on my ram air....got it off ebay very similar to the ram air box just alot alot cheaper just had to get some nice aluminum 4" tubing from the hardware store...i originally used some dryer ducting just to see how it work all fit....here is a link to the housing i won....
