Gene, what about the compression effect that the struts of the grille make on the air when traveling at speed. Some of the older jet engines used to have large cones directly in line with the center axis of the intake turbines specifically because of this effect.(specifically the Russian mig 17 and mig 21 come to mind) Now I realize things change drastically when you compare the speed of a jet traveling at altitude to that of a truck going approximately 60mph, but the compression does occur. Did you take this into account when you made your modification and the possible detremental effect on air flow going into the genedad modification?
As a general rule, anything you put in front of an opening will reduce the air flow through it. I intentionally said "general rule", to account for my experience with TAG's, but the opening going into the turbo is a special case that's quite unlike the one going into the radiator. The struts on our PSD grill are somewhat streamlined in front, but if you reach behind them they're hollow, and terminate with a sharp discontinuity on the upper and lower trailing edges. This creates a lot of turbulence, which can impede air flow, and also re-direct some of the flow up and over the hood.
I think grills are for styling, providing a place for the OEM logo for free advertising, catching large objects so they don't hit the radiator, and they divert some flow around (instead of through) the radiator at higher speed to reduce drag and increase MPG.
The cones you refer to are intended to divert incoming air from the hub of the fan where it does no good, off to the perimeter where the blades can grab it. The reason they're pointed on jets is to deal with the trans and super sonic air flow.
Maybe if you take the scoop from a snow blower and mount it up on the grill, of course attatch with duct tape, you could funnel more air in there. Just a thought.
Gene, I respect what you are trying to accomplish, but we must clean up the looks.
please refer to the picture below and order and Ambulance grill that already has the Ram Air funnel. Otherwise some slick lawyer is going to chase you down and say he can represent you for the accident.
If you wanted to give it a more cleaned up custom look you could always attach one of those chrome funnel tops off an ash can you see at the stores. That would kick a**.
ROTFLMAO!!!!!!
Man that is funny.
Gotta hand it to you though ernesteugene, you are a pioneer!

On Friday mornings they have alot of stuff for sale at Wheeled Coach. If you want I can look for one of those grills for you, Gene. I might even find one with the lights so you could give the birds some light while they make a nest.
I really think he's playing a joke on us. Or perhaps, he was like the guy trying to trim his mustache in the mirror "just a little bit more.....OH NO!"
I think that in a couple of years your truck and fiver will look like they belong in a MAD MAX sequel!! I can picture it now, an old psd running down the road all beat up and patched together pulling a custom duct tape fiver laying down a cloud of coal chasing a small TDI Jetta with your wife hanging out of a custom suicide door (duct tape hinges of course)with a machine gun mounted trying to run them off the road so you can steal their fuel. Oh yea, don't forget you will need a gyrocopter.
O.K. after looking real hard at Genes pics, I call August Fool on all of us. Notice how there is a big bent spot in the fins, and what looks to maybe be blood stains . notice also how the horizontal piece directly below the hole has what looks like chips and scars from maybe a large bird hitting the grill at speed. I think Gene alluded to this in his own words of ---Being able to reach up in the intake tube and remove birds and small animals---.
Come on Gene, come clean. Is this for real, or in that last trip did you have an Up-Close birdwatching experience.
