Working with very little depth here... (Yea yea I know... that's what she said) I don't think a typical cone filter will work.
Was thinking of using a flat filter like below and modifying a factory airbox. Anyone know of a nice centalish location OEM air box that fits this bill? May just have to fab one from scratch, but using a factory box would sure be easier.
Working with a 5.5" inlet BW "race" cover inlet.

I was thinking about building a box around my f1c the front side against the radiator shroud originally with panel filters all the way around to emulate nothing at all on the intake. Ultimately I put a cone on it with a fabricated short radius 60 the a 90. I looked for an answer like yours. The other thing I considered was the big box would mess around with any and all maintenance.
ive built a ghetto but working filter once out of a stock filter once..... I used thick gauge wire mesh. Bent it aound the turbo inlet and trimmed it. then made another a little longer. I cut the factory air filter and sandwiched it between those two inlet "screens" and hose clamped it on the turbo inlet. Worked perfect!
It was like this just cost nothing since i had the stuff laying around
I live fairly close to oscs and blown06, would like to look at both of theirs but have been doing good to look at mine with all of the stuff that seems to get in the way!
Got ripped off so hard by the seller I’m still bitter about it! I’ll throw up a build thread eventually. It’s on the back burner for now. Getting the RX-7 ready for race season. Only have a month or so to get it all finished!
Here is what it was suppose to look like.... What I got looks nothing like the pics though. It's been beat to hell since then and is in very poor shape.

I hadn't seen the foam "turbo guard" yet. Thats interesting. The actual filter media Area without pleats though is pretty horrible. I had ordered an edelbrock low profile carb filter yesterday. It has a 5 1/8" carb opening. I figure I can modify that to 5.5" and use it until I can find a better solution. Was $22 shipped.

Id like to see that too. Hoping to get some sort of "Real" filter installed. I'm guess some before and after dyno runs with the small mesh screens like I have installed and foam turbo guards would show some large restrictions. The inside of the intercooler and turbo on this car looked horrible from running just the screen on the street. Full of grime... Feel sorry for the old motor he was running. Little brake clean and an intercooler full of gas cleaned it all up.
Everyone claims Filter is better however I picked up 1 psi from 13.5 to 14.5 when I was on the dyno witht he F1C and a big pulley. I will be back at Frank Soldridge place psi speed solutions after Ducks race in Georgie and finish tuning the new set up.

Are you talking about with and with out a filter of any kind? Or difference between turbo saver and filter.
Also did you use the turbo-guard with the small mesh screen like so...
If I can’t make the Edelbrock filter work, I do like how easily the “turbo-guard” comes on and off. Thinking I could box in the area below the inlet to isolate it from debris. Then run the foam turbo-guard on the street at low boost and pop it off and/or replace it with a larger screen at the track.
I was also thinking since this is the 5.5” inlet on an 80mm turbo, the full 5.5” inlet surface area probably isn’t needed. Screen covering up some of this shouldn’t hurt performance as badly as it would on a smaller or non-surge inlet.
filtration and flow is all about surface area...and that foam thing over the front has none. But you are kinda screwed for space. It ant gona be good no matter what you do...other than moving the turbo.
I agree. Pick which one matters more to you. Probably going to be next to impossible to get something free flowing in that tight space.
