ya, my 88 dak used to have the same setup. I drilled acouple holes in it so it wuld flow abit better.

but acouple people have switched to that set up. I know meangrean did. and he noticed a difference.

 

my truck still uses the Stock air box but i removed the tube that draws the air and replaced it and ran it in between the Headlight and the radiator so it gets 100% air from outside the engine bay and is somewhat forced in when driving down the road.I alwaysstick it back in the fender when it rains though.

 

I got a CAI on ebay as well and it cost me 27 dollars with shipping. Thats about seven dollars more than you would pay for a stock filter, and the throttle response i noticed was way cool. I never got that with the stock air filter. and no my air isn't cold but it diffently has a better air mixture going on, so i guess to answer the question the yes it should be called "fairly luke warm air intake"

 

Different solution: Reflexxions cowl hood with the center bracing removed. K&N 14" round filter w/K&N X-Stream filter lid. Modified 'shaker' hood scoop (bottom half) as cold air box. Does it work? Yepper! Above 40mph the cowl works like a champ.

 

what happened to the experement i wanted to see the #'s!!! [:-][:'(]

 

I was looking for this post too, but I couldnt find it. maybe virused got a lil side tracked and forgot about it.

 

guessing so i havnt seen his posts latley

 

Why wait for someone else to do this experiment?

Is is not true 'science' unless two people do the experiment
and find that their results about the same.
{they never exactly match. Perfect matches are signs of fraud}

Here's some suggested ways to do the air intake test:
-----
Two great American brothers
with only high school educations
had a DIY project
that they eventually called the 'Airplane'
but like the Wright Brothers
you need to do your DIY project with careful testing.

If you want a real answer you can trust about an air intake design,
then........

Go down to Sears and buy one of the $30-70 multimeters with the temperature
probe. Sometimes they are on sale for $19

Later you can use this relatively cheap multimeter and its Type K thermocouple
to 'balance' your exhaust gas temperatures by swapping around the highest
flowing fuel injectors to the highest flowing intake ports....but that is
another story.

Then buy one of these $30 gauges that can measure low pressures and buy a
length of plastic tubing about 10 feet long to attach to it:

Get the 30/30" pressure model.

If you don't want to spend this money you can also make a simple "U tube
manometer" with just a 20 foot length of clear plastic tubing and a yardstick:


Now drill small 1/16 th inch diameter holes in your stock air filter housing
and air inlet tubing,
like at:

1. at the begining of the inlet tube
2. in front of the air filter element
3. behind the air filter element
4. near the throttle body connection

Put a fresh new air filter element in your stock filter box. Go out on a road
with little traffic and measure the temperature and pressures at your small
hole test points of the stock system when the engine is at wide open throttle
through the 2000 to 6000 rpm range.

If you find between two points that the temperature goes up, then the air is
picking up heat in that length between the two points. (i predict you won't
find much heat pickup)

If you find that the pressures go down between two points then there is
restriction in that section, like across the filter element ( i predict you
will only find a small restriction across the paper element of the filter)

Now try moving the air inlet to the stock filter box from its stock location
to other places - like the grille top or bottom. Look for a place where the
pressure is highest and the temperature is lowest. (I predict you will find
that the cavity behind the firewall and below the windshield will be best -
this is also where your air vents pick up air to ventilate the truck's cabin)

Now, if you are a bit more adventurous try the following experiment:

With all the stock air system in place, put the truck in 2nd gear and measure
with a stop watch how many seconds it takes to accelerate from 3000 rpm to
6000 rpm with wide open throttle. Do this test 3 times and average the
result.

Now if you are a little more daring and have found a clean road with little
dust in the air, think about doing the following 2 tests (it is optional but
informative)

Do the same test from 3000 to 6000 rpm, but with the paper air filter removed
from the box, and the box closed back up. This is the 'no filter but cool air
pickup' test.

Then do the same test, but with the air intake system removed and the throttle
body opening sucking the hot air from underneath the hood. This is the 'no
filter hot air pickup test.'

The above tests sound dangerous without an air filter, but I can tell you
that many highway patrol officers removed the air filters on their cars in the
1970s. I have personally seen people pour uncooked rice down carburetors to
scour out carbon deposits. Lack of an air filter over long periods will cause
the bore walls and piston rings to wear out much quicker, but a quick test has
little effect unless you are unlucky enough to get a large chunk of something
down the throttle. If you are worried you can cover the throttle opening with
some eighth inch hole window screen material or mesh stocking. Note that these volunteers did open open throttle/no filter test of a 5.7 Hemi in an LX on a rear wheel dyno:

look at runs 7,8,9 and see how the hp was down compared to the 280 hp of the stock factory airbox.

Now go order the aftermarket air inlet systems of your choice and repeat the
pressure, temperature and 3000-6000 rpm acceleration tests in 2nd gear. Send
back the systems that don't do as well as the best for a refund of your money.

Report your results to automotive forums.
You will be a hero to some,
the worst possible news to others selling junk.

 

WWWOOWW..........Thanx Hankl for posting the Dino results....

Thats about as controlled of an experiment as you are going to get.....

Boy there sure are allot of big claims out there by companies....But it looks like stock is just as good.....

Interesting.........very interesting

 

very good info kinda what i was thinkin! but i never had the time to do that!!! thanks!
