hmm...lets see...before everybody goes...what on earth...this is what i'm using for my "ram-air" intakes...yes...intakes...plural...i want as much freakin air as I can get...and I figure...hey...got all that space under there anyway...so why not use it



gonna mount all this dung way up under there...where that piece of crap plastic thing used to be...whatever it was...some sort of aerodynamic something or other...it died...shattered...looked tacky with ducktape holding it together...even after I primed it...so...yea



those are stove pipe 6"to3" reducers...and a 3" sewage T pipe...i've got that black stretch hose stuck in there with some self tapping screws...straight thru the hose itself...the reducer on the far right is held on with zip ties and electrical tape...should hold just fine



reducer on the left is held into the pipe with two self tapping screws...have to be careful tho if you crank it down too tight that 6" funnel top pops right out of the neck...oopsie...but atleast it goes back with a little coaxing



and...the old intake hose I already have hooked up...goes in on the open 3" hole...guess i'll just crank some more self tapping screws in there or something to make it fit...I dunno...figure that out tomorrow



phew...one things for sure...every time I do these projects I get high as a kite...remember kiddies...always open the windows when spray painting within the house

NICE! ill top that let me think of something new

Falcoln: if you lose the flex hose and replace it with hard pipe you

will pick up a good deal of flow. I once used 4" aluminum flex with

less severe ridges and even that was restrictive enough to choke up

the intake at high RPM.

how can u tell that ur cars choking up from the low flow of air going into ur intake?

i was driving the CRAP out of my tonight...taking it up past 7k...no stumble...no choking...but i've also got two things down there to catch the air...so perhaps that does the trick...I dunno...seems to be working ok tho



i'll tell ya how it performs the weekend after next...when I take it onto the drag strip



really hoping to go up against some rx-7's if they show...also get to race my friend in his 350 trans-am...should be...interesting...

im thinking maybe get some glass to fit in there, i got a ghetto idea of using my lava lamp lol and taking out the filter andd maybe throw some foam inthere on the buttom of my glass intake and let it hang there, give me some advise!

It was running fine before the mod, then started stumbling at high RPM after

installing the cold air intake. I was able to get rid of the stumble by installing

smaller carb jets - this would tend to indicate a flow restriction.

I changed back to my normal jets and converted to the cold air box setup

with no hose at all (intake air came from the cowl area). No problems at any

RPM with that modification.

show me a pic man of that set up

and show me were i can get a cold air intake set up

Sorry, no pics - that was a long time ago. I basically just made it

from whatever I had in the basement that day. As I recall I made the

base plate from fiberboard, and used plastic lawn and garden edging for

the sides. Eventually I padded it with insulation so it wouldn't pick

up underhood heat. This was for a Holley carb - for a stock carb I would

probably just grab a spare air filter assembly and cut a big hole,

then fab some ducting up to the firewall.

Getting air from the cowl area does have the problem of being the same

place your fresh air comes from - might be a problem with gas fumes.

It may be possible to get around that somehow.

On the plus side, there's virtually no restriction and the air temps

go way down. My thermometers wouldn't read over 122 degrees so I

couldn't always get an underhood reading, but temp inside the box, even

at a standstill, was barely over the outside air.
