Theres a lots of good info/insights people are comming up with here.

BLUEMDsrt6, theres nothing wrong with you asking questions trying to figure out which intake is right for you.

Heres my opinion, which isnt worth much...

First off, filter placement. The ideal location of the filters would be in front of the radiator support just behind the bumper/grille area. Thats where the air would be coldest and most dense, not to mention the ram air effect. So long as water intake isnt going to be an issue(which it doesnt appear to be), i have seen great results on every car ranging from vettes to turbo 240's, etc running the filters in this location.

Second is the volume of air you can get in the engine. The BDJs huge dual 3" pipes are the epitome of this. As long as the supercharger is capable of sucking in the additional air (which it is) then you have that angle covered.

There is also the question of turbulence some people have brought up. Keep in mind the s/c pulls the air in from the y-pipe not the other way around. In my book, this is even more of a non issue considering no matter how smooth you get the air to the s/c it becomes pretty darn turbulent from then on as s/c compresses the air and creates boost.

Another thing to consider is material used. Aluminum is the cheapest, lightest, easiest to work with, etc available for an intake. But it heats up. In all honesty id like to have dual 3" pipes made from plastic. But until i find some perfectly prebent 3" plastic tubes this idea goes out the window. The simple answer to this delima is thermal wrap. I honestly didnt expect it to work as well as it did on Brians car but after he drove 20min then popped his hood and the y-pipe was cool to the touch i was a believer. As far as how it looks asthetically....thats a personal opinion.

Hypothetically the best intake would encompass all the above. It would pull in cold air from behind the bumper, conduct as little heat as possible, and be generous in size. Most of the current intakes lack in one dept what they make up in another. Both can be thermal wrapped, so thats a moot point. The Needswings intake pulls in cooler air but has a restriction at the radiator support passthrough. At a standstill the BDJ's draws warmer air. But who cares about performance at a standstill? As soon as you take off air is flowing through the engine bay, not to mention the fan helps too. The BDJs pulls in warmer air, yes...but not only do both tubes remain 3" all the way to the throttle body, you also have 2 of them. And with the factory passthroughs cleared out of their stock hardware...its literally a straight shot for air to pass through from the grille, dont believe me look at his pics in his other thread. Thats why its my personal pick.

We have tossed the idea around of trimming the core support for more clearance, hell you could even buy a different size radiator and possibly have clearance for each tube to reach around the sides into the bumper/grille area without altering the diamater. But thats getting a little extreme for a street car.

A word on those accordian bellows...they are a great design as far as compensating for engine movement, but they are far from optimal in the performance dept. The repeated angles of the design dont allow air to move smoothly through them. On LS1 engines (z28 and TA's) switching from the factory bellow to a smooth coupler is worth 5 rwhp every time. Not a monumental gain but while were talking intakes i figured this was an appropriate topic to address.
