im curious of the effect of removing the plastic liner that channels the air up and to the front of the condenser. surely you would have wild air coming in with no directed path and therefor not be forced over the radiator but yet will stray other places. over and around is what im getting at.

What are you guys using to block off the original air inlet? I saw that one guy used foam, but Im sure it never stays in place. weatherstripping maybe? I have an SS and Im sure at higher speeds the little bit of air the hood actually pulls in will blow the foam into the airbox...

I used to have that block of 2x2 frost king foam, but it started getting pushed OUT over 100mph. Found some thinner, like 3/4 or 1x1 foam with a stick on bottem just stacked them in 2layers. Same stuff I used the seal the lower duct pan (with the 2 holes) To the lower stock airbox. Its all sealed off really good now 
I re user the stock 2 piece rad duct box thing. Just had to notch it fro the tubes. They block a little, but more make a V, that the air gose around the tubes. But without the AC condencer there alot more room then everone with the SLP/FTRA sqare duct that block the middle, and is alot closer to the rad.

thanks, I need to seal mine...I left it open, and didnt know it would hurt my power.... what and where is menards? Ive never heard of it. Hmmm, I have the FTRA and Im wondering if there is anyway I can do the SUX2BU mod with the FTRA...

a tank has three lines connected to it...
line 1 has 20psi
line 2 has 10psi
line 3 has 5 psi
what is the pressure in the tank?
it isnt 35psi...

You'll have to many holes. What pressure is builds up from one will just escape through the other.
What he's saying is that, if you are getting 20 psi from the bottom of the radiator and 10 through the bumper, your only gonna have 20 at the air box. So one or the other but not both. If he double the size of his hole at the bottom it would possibly gain but the pressure would be more consistent with no where to go.
Now, if you had a big enough motor that could starve the airbox with either setup then both would help, but that's never gonna be the case.

oh yeah the motor is pulling way less than is being supplied...i have found with my air box even at 30mph i had more than enough air...positive pressure inside the lid even after the pressure drop from the filter...check out some past posts in the advanced section about ram air...

it works because it is pressurizing the air to an extent, the speed of the car is acting like a turbo in essence. forcing air into the motor, more air than could be pulled in by the motor itself so by creating a big opening then the air being crammed up thier is just going to escape out of the other hole

think of it this way pretend we made subtracted 10 from each of the inlets...so now we have 10psi at one inlet and 0 psi at another so that means that there is 10psi inside the box...
so the max you can ever have in the box is 10 psi...in a way the box has a hole that can be sealed up to a max of 10psi (which is the weaker system)

yeah you have it to an extent but the pressure in your senario will only be 10 psi...the 20 will leak out the inlet of the 10 psi...

So your saying since there are two openings, even though they both face the same direction and are being hit with the same air speed, will not flow more to the airbox? And your saying besides this point, even if it does flow more, that it wouldn't help any b/c the air that can be pressured in the intake has already reached its limit with previously stated setups? What about the BIG GULP ram air from this board. Do you not think it would pick up more than a SSRA style? Seems to not be completely consistent...
I don't want to come off argumentative, and don't mean to. I am just trying to discuss...

and no my water temps also stay under 190
so there is a max where no more air will help...
