I can't run taller than 3" with anything larger than 12" as I've got to cut too much out of the bonnet. I am pretty sure 12" is wider than the top of the scoop and 14" is wider than the base of the scoop. I could probably squeeze an 11"?
I've seen the 10"*5 one on a few cars around Hallam Performance hence why I looked @ it. I know there are other manufacturers that do similar stuff but so far I haven't found any. VPW has some smallest is 11" which I think I can squeeze in.
Aircleaners only going to be used for street use. With the 14*3" I reckon I drop back to about 160-180rwkw. lol
I've only ever used the elcheapo 14" chome and standard 3"filter. But I have played around a lot with spacer plates (1"open and 4 hole), drop bases and running without.
For my combo the standard set up got the quickest times. Everything else lost tenths and Mph. Running without an air cleaner I found slower not to mention the chance a stone or bug or cat might get sucked in there!
I use a 14" x 3" K & N Element with a recessed base and an XW GT Lid (with XB GT Air Cleaner Sticker of course). Fits under the Bonnet with a Single Plane Intake and 2" Spacer.

Something's up if it won't run with an air cleaner on.
It's like trying to let the engine suck air though a 1/2" pipe. Thats the easiest way I can explain it. It just floods @ idle/primaries and secondaries with an aircleaner on. Which tells me I aint getting enough air to make correct mixtures.
As soon as it's removed it idles as per normal. I'll fiddle with the idle mixtures tomorrow but thats still not going to fix the flooding with the primaries and secondaries. As you saw with the chart there isn't anything wrong with the jetting
