1. The lid should work fine on a regular lower air box setup, however by adding the funnel into the upper lid this will have reduced the volume of the airbox, this would most likely negativly affect airbox resonance for a 346ci LS1. It may be better suited to lower displacements though.
2. On a FTRA setup of similar the funnel respresents a narrowing of the passage, at sub-sonic speeds this will have an adverse affect as it will speed up air flow velocity but reduce air flow pressure.
It will in essence be an "anit-ram air" setup.

The only methods I've seen of succesful air intakes involve several aspects:
-free flow filter (but not k&n, remember a filters primary job is to filter and cotton weave filters are particulary poor at this, paper is about the most efficent at filtering and the stock OEM filter has been flow tested to 500bhp n/a after that you want to look at sythentic weave filters like the Donaldson Blackwing for the C5 Corvette. Some foam filters are quite good but the poor ones are very poor).
-cool air ducts, this is simply ducting to an outside air source so the the IAT's should remain closer to ambient as opposed to taking air from under the hood. This is what 99% of all "Ram Air" systems are.
-air box resonance, tuning the airbox to the harmonic frequency of the engine.
-Ram intake track tuning, same principle as air box resonance but with the intake tracts in the manifold.
These are all proven techniques used extensivly in competition the world over.
Remember to see a "Ram Air" affect you would need to be traverling around 200mph.
Personally I think your CAD images look pretty but I think the physics behind the design is not upto par.
Seriously just make a simple lid based off of a proven design and offer it in 85 and 90mm openings and sell for like $80 shipped (US mainland) and you'll make a killing.

Arnt there pattents out on the other lids? Where id get introuble if i took one and reproduced it just with a bigger whole?

I say test it out and see how it performs.

ehh oh well I tried. im only 17 but I try to think outside the box and use old and new ideas and combine them to try and make something out of it. but I say it should be tested at any rate!

Also you could make a small variation on the idea so if any where pateneted it would aviod this issue.

And it's generally new idea's that come from young people (I'm one of them). I've certainly tried to think outside the box on more than one occasion however most times I find it's already been tried
Still doesn't stop me trying though

how about everyone measure the lid they have now....i keep hearing people say they want a 90mm lid..I measure the stock lid and the opening was 90mm.I measured my whisper lid and the opening is 90mm.So i still dont know what another 90mm lid is going to do as it will be the same size as other lids.

i think the opening for the lid has to slide over the stock tb, thats why its that big... like the 90mm throttle bodies, the opening is that big, but for the lid to slide over it, it would have to be larger than that... i think.. anyone else?
