cheap but affective, homemade cold air intake

[atyates]

I did. i just didnt feel like i got as large of volume of air as i did without the box.

looks really clean- almost better than most aftermarket intakes.

if anyone else does this, could you try running numbers to see if it actually makes a difference? from what I know/read Vortec intakes can't be much improved upon by sucking air from under the hood....



.....unless of course we are talking about a blower

So one last question. What did you do with all the plugs and electricals that are located by the filter?

this is a very quick cardboard cut out of what i plan to do as a heat sheild. and my brother bought one of those electric turbos off ebay that you wire up, he seriously thought it would work, well hes giving it to me and im going to put it in that whole in front of te filter where the factory airbox went in, so it will suck all the cold air from outside into my large, new air box, so that way i still have cold air plus a large volume of air.. then im going to fiberglass the outside to make it smooth. and even after i do all that i will have a cheaper CAI than you can buy..

So what about the electronics? haha

first thing i did was cut this piece off the factory intake tube

then one side of the mass air flow sensor hooks directly to the filter

then you take the peice you cut off and conect it to the other end off the MAF sensor and the other end to the new PVC intake tube

then you just tighten down the clamps. and what I did with the ambient air temp. sensor is, take it off the factory intake, drill a 3/4 inch hole in the pvc behind the maf sensor, and squeeze it in the hole

Lol, "electric turbo".....otherwise known as a boat bilge blower assembly. Used to evacuate gasses for the bilge area of a boat.

Really, they're pointless and end up being a restriction if placed ANYWHERE in or around the intact tract.

In all seriousness, toss it in the trash and don't look back....

it should work for the purpose im using it for. its not like it will hurt putting it in the hole in the fender.. and hes just giving it to me..

Actually, you are.

The fender is an area of high pressure air (it ducts from behind the front grill) the engine bay is an area of low pressure, behind the filter even lower.

All a fan in the opening is going to do is churn up the air and make it more turbulent. Blowing the air at the filter actually blows it past the filter which makes the pressure over the surface of the pleats lower, the opposite of what you want. You want the highest static pressure on the outside of the filter as possible (hence, sealed box to the fender) so you have the biggest pressure differential possible between the outside of the filter and the inside. this is what pushes more air through the filter and thusly, into the intact tract.

That's probably not my most elegant explanation of how it works, but that;s the nut of it.

You best bet is to reseal the intake filter area to the opening in the fender.

You'll loose the "whoosh" sound, but the performance and mpg will be better....
