This is a most interesting thread for me. I presently have the 9" air cleaner 2 3/4 k+n filter element, turkey pan set up. I love the way it looks. I have found out that this filter is only capable of flowing 470 cfm, clearly not enought for a 428 with a big Holley DP. So I am looking for a way to get a lot more air and keeps the traditional look under the hood and on top of the hood
More research the other day, I found out that the long oval cobra air cleaner flows no better than the little one I have on there now(reduced height for hood clearance). I am shocked no one has designed a drop down base for the big oval air cleaner, I called k+n and the have a 3" filter element for this, it measures 20.81Lx9.5Wx 3H, it will flow 950 cfm, this to me would be perfect! Now, to make it perfect, would be to design a turkey pan to mount to the intake manifold flange(like the present Turkey pan), only shaped to accomadate the long oval filter.
Now, as far as providing air for this much increased cfm potential, I know under the hood air availability is a real question mark, especially at speed. Dyno guys have told me they have much increased numbers just taking the hood off and doing nothing else. I was thinking of a RAM AIR setup coming from the two 7x3 holes in the front, ducting it outside the wheel well and then entering it into the engine compartment thru the wheelwell housing. Location would be about 1/3 of the way back on the valve cover.
Mount a flanged adapter on each side of the new tukey pan that would accomodate a 3 inch brake ducting hose.
I think this could be a real clean, very effective and very good looking set up.
Pegusus has ducting and adapters, I am sure there are more sites that have more choices, this is as far as I have gotten so far.
Has anybody attempted anything like this yet, I don't want to recreate the wheel if has been done already.
To compliment this I would opt for new sidepipes with the spiral core option that I talked to Maurice at Unique about, to free it up so I can take advantage of all that available intake air I would now have. Then of course it would be off to a dyno to dial it all in.
