Apologies if this is long and possibly a repeat of another thread.
I have been thinking about the air box design on my Mondy, and am thinking with a bit of logical thinking and effort the may be efficiency gains to be had to the air intake system.
Currently the bore size, entering the standard air box appears pathetic for the volume of the air box, It also enters the air box about 3 inches lower than the MAF housing with the filer in between. This to me means the engine will have to suck harder (giggiddy) to get the volume air flowing from the air inlet into the box.
So my thoughts are to either source or create a new air box and CAF.
my considerations are as follows
The CAF ideally has to be straight and as direct as possible. made from a lightweight and thermally reflective/non conductive material. The shape of CAF should go from the largest bore size to the minimum bore size acceptable, in a cone shape to exploit any benefits to be had from thee Venturi effect.
The air box shape should assist the sucking efforts made by the engine and include a filtration element, whether a cone or a panel. The air box again should be made from thermally reflective/ non conductive material. and at all times ensure the air flow and velocity is disturbed as little as possible.
One other consideration I have had is that where the filter is not at 90 degrees to the air flow especially in kits or designs that use a cone filter housed in a tube. that the air pressure at the base of the cone is greater, due to the reduced volume. Therefore the air flow here is greater, is it then safe to assume that due to an increased flow of air at these points. The weight of filtered particulates is greater therefore over time these areas will get saturated with particles sooner than areas near the tip of the cone. Therefore giving an area of uneven air flow causing the flow of air to be turbulent. A balance therefore should be struck between surface area and even flow.
Therefore in a perfectly designed system the CAF will be a dead straight carbon fibre trumpet with a filter of largest possible size at the largest bore size along/down the trumpet in line with the MAF housing and Throttle body.

thoughts and opinions are greatly appreciated thank you ?
