Yea I know about the sealing of the box...I just want to get rid of the acordian tubing..

I changed my mind about using the open CAI. I'll just use the stock box.
I also what to get rid of the accordion tube. I might see if I can cut the tube from the open CAI kit and make it work........if I ever get time.

I looked at doing that on mine, but you'll have to have a custom one made because of the two bends that will have to be in it. I've pretty well settled on a Volant system for mine after I get my step side bed painted and installed.

It's far down the list of things I want to do to the truck. Might be a while.
I went completely back to the stock air intake including the Vortec box.

Thanks for the tease....yea mines pretty far on the list also...trying to work my lift and new tires in...most likely it will have to be after taxes

My theory was proven correct on the screen in the MAF sensor last night. I was called out at work to look at an air flow meter for our new power boiler.

While looking into the issue, we pulled up the blueprints for the sensing element install. Turns out, it has the exact same honey comb grid in the 5' pipe just ahead of the sensing element. It is referred to as a flow straightener in the blueprints.

All right, but with some CAIs it already has a straight pipe and doesn't have to come out of that 90 degree turn that is in the factory one, so would that make any difference? For example, the Volant on my 454 has the MAF pretty much directly attached to the Throttle Body, so would the lack of a flow straightener really make any difference? And on a 350, what if you attached the MAF to the TB hat side instead of the air filter side?

I'm thinking of fabricating a completely custom setup for the Tahoe. The Sierra already has almost no tubing due to where the TB sits on a 454 anyways. After looking through my Photobucket, I realize I STILL don't have a current engine bay photo, this one is from when I was still putting it together, but you get the idea.

The idea is for the maf to see a true representation of the air mass ingested by the engine.

As long as it's not subjected to eddies or turbulence that changes the MAF sensing, you're good.

Basically; the air has to get a stright shot at the MAF element.

The problem is; unless you've done modelling and testing, you don't know if this is what's actually happening or not. Everything from turns to piping diameters and length can effect that.

Off the top of my head, I would suspect that the OEM "screen" is in place to ensure the MAF gets clean flow of the air mass free from turbulence....everyone seems to think OEM engineers don't know what they are doing or are making power robbing compromises everywhere when that is usually not the case.

They're pretty smart dudes.....

It's not that we think they don't know what they're doing, or at least I don't. I just know that they designed it to work with the way they set it up, and if you change that you're changing how it works.
