Air Intake switch.....

well, AJM and i switched air intake systems....i pretty much got done with puttin' the ram air setup on my truck. i just need to adjust the vent tube - AJM, the thingy is out tomorrow [img]/wwwthreads_images/icons/crazy.gif[/img] ...i forgot to send him a connector for the TBI/ventube...lol oops [img]/wwwthreads_images/icons/tongue.gif[/img] anyway, here are the pics.

i was running around a couple days without the tubing on 'cause we were fabbing the passenger side fender connector. in those days, i found that the truck was a little shy on power. the 1st to 2nd shift felt really weak...especially 2nd gear acceleration. i took the truck out tonight to see how it ran. the truck pulls a lot better now. i notice it especially in the 1st to 2nd shift...and 2nd gear acceleration has a good push behind it. anyway...here are the pics...

Re: Air Intake switch.....

passenger side bracket...the connector tube was inserted through a .25" piece of metal. then the inside and outside edges were siliconed for a tight seal. then i spray painted the thing black.

Re: Air Intake switch.....

driver's side...this connection was a PITA...mainly because we removed the grill so we could insert some screws in a few tabs on the connector. that way i wouldn't have to worry about the thing coming loose. anyway, i wish i would have gotten some pics from the front of the tube whn i had the grill off...but, this will have to do for now [img]/wwwthreads_images/icons/cool.gif[/img]

Re: Air Intake switch.....

That came out really good. As you may know I bought the stuff to do a snorkle but I am having a tough time routing 4" pipe through cab. 4" doesnt look that big next to 6" and 8" in the store. I need it to come up behind the cab and the intake will stick up over the roof. I may have to run two 2" pipes instead. I will have to look into mixture adjustment since it will likely run rich after this. Again yours looks great. See ya.

Re: Air Intake switch.....

two 2" pipes won't flow the same ammount of air as one 4". Be sure you know your cfm requirments and do the math before you install it.

Re: Air Intake switch.....

How about you do the math??? LOL. 10ft of 4" pipe into K&N filter with forward mounted scoop on roof. Edelbrock 650cfm plain jane carb. Putting spring loaded needles and seats in while it is apart. I think it should be ok. I cant imagine it being restrictive with 4" pipe. Thanks.

Re: Air Intake switch.....

BTW Shorts, looks good. Almost thought I was looking at AJM's rig until I saw the paint job!

Frank, your fine with the 4".

I was refering to the idea of using two 2" - example:

a 4" tube 12" long has a volume of ~150.78cu/in.
a 2" tube 12" long has a volume of ~37.7 cu/in.

So you would need two 2.8" - 3.0" pipes to equal the same volume as one 4" - same theories apply to airflow (CFM).

Re: Air Intake switch.....

Sounds very familiar Frank, thats how all my other buildups have been. But things have changed since I started working on the puller. Now I think it thru 1000 times before I start something, just to be on the safe side of things and to make sure I'm not just wasting my money. Thinking really hard right now actually about just using a D44 instead of a D60 in the front for the simple reason although the D60 is stonger I am sure the D44 will be ok. And I can buy 4 D44's for the price of 1 D60 with change to spare.

Re: Air Intake switch.....

Whats the axle diameter difference like 1/8" or something? I would have kept my D44 looking back on it now too. Not to mention the weight and anguish to get the D-60 in. Good move.
