Minimum engine/air box to bonnet clearance

When I originally started designing the air box my design criteria included,
.it must still be able to fit ram tubes inside the box
.I need to get quality air filtration with multiple filter type options.
.potential to be ducted to cold air if desired
.must be easily removed and serviceable
.has to be able to allow for the heater hoses still to be used, I could have run them underneath but I wanted to be able to see them for visual and physical inspection of wear or potential failure. You may notice that the hoses sit nicely with the top of the box, this was no coincidence.
.have potential to be plumbed into the PCV engine breather, this should be fairly easy to set up and help reduce any oil leaks.
.lightweight
.have a plenum as large as possible.
.it must look like it belongs there and potentially look like an OEM part. I considered trying to match the original finish of the heater box. The fibreglasser says that he can also make these out of carbon fibre. This one pictured is a heat and fuel resistant resin.
It's still early days but I think I can tick off most if not all those criteria.

I've painted it in black polyurethane which is fuel resistant just incase I pull out any jets etc that then drip fuel onto the air box. It was meant to be satin black but turned out a touch glossier than expected.
Can any of you guys who are running webers please give me a measurement from the inner guard to the lip of the ram tubes on barrels 5 and 6 plus from the firewall, I'm curious if we can fit this with other manifold types. If we can make it fit I'd be interested in getting some expressions of interest on these and I can then pursue making more for those who are interested.

You sould definitely make an undrilled one for those of us running proper carbs

Obviously it's much easier for me to supply one without drilling the backing plate.

Top job James
Thanks Gene.
So can anyone with a redline or other manifold fitted give me a measurement on the clearance between the ram tube lip and inner guard on the rear carb?
Thanks James

If you can also measure from the top of the chassis rail to the centre line of the barrels on the rear carb, just as an extra cross reference.
From what I've been told so far the redline manifold sits around 15mm higher than my Seton manifolds which would be quite beneficial.

Have you got ram tubes still attached and any filtration? Are you going to duct it to cold air intake? What materials have you used?
Cheers James

Initially we built firstly because filters were gonna cost small fortune. This had ak&n pod on the front.
Was sheet ally which we bent up on a cheap hare and forbes panbrake ($300ish). Outer face is fully removable by means of Allen head bolts into nutserts. I used some rubber as seal from Clarke rubber.

its great to see some innovative airbox designs and that someone else is mad enough to make one up. i saw one on a group NC Charger at the Noose hill climb, I should have snapped a pic. this brute of a Charger makes just over 400 HP.

I'm surprised that none of the Su carb guys are tackling this that I've seen. Once again they'd have more room to play with than us and could possibly use an off the shelf item from BOI PERFORMANCE or EFI HARDWARE.

We are thinking about it
Chargers don't necessarily have more room, they have a strut tower in the way.

I designed mine so that it points directly to the space between the headlight and radiator to possibly get air from ducting through there like in the picture above but I can't bring myself to put such a big hole in my radiator support panel at this stage.

I did this years ago. Twin ports with long tubes back to twin GRA throttle bodies. Filters in front of the rad support. Cold air with a ram effect from the air well behind the grill. Worked pretty well.

Yep my LC has 2 holes very similar.
