Air Filtration for Race Airbox / Air Intake
 

Phil or anybody else with the race air intake & race airbox setup.
I've just been reading the threads on air filtration in the 9** section with great interest.
I'd been toying with placing the air filters over the top of each bellmouth in the airbox, but on reading this I think a solution is needed nearer the headstock. So the question is what filtration solution have you fitted (if any) to your airbox / airtube ??

On the front mask fairing, I stuck two pieces of plastic treillis, issued from an aquarium shop ... a cheap solution, why not ???

Then on the frame, a piece of mosquito net !!! (please don't laugh ...)

And into the inlet trompets, a round handmade filter managed with alloy treillis ...

As you can see, the carbon fuel tank 1993 model is open ...

... reason why I decided to make a removable obturation with carbon plate in order to secure my engine !!!

With the 926, I kept the original plastic filter referenced : 46010241A !!!
But my first solution is appropriate too ...

exactly what I've done !

yes - I like this idea, think I'll do something similar, but I'll try to fix some sort of panel filter between it and the airbox...

but I'm not sure of this one ? I'll try and avoid putting anything into the intakes.

The tank - well I don't think it should be open ! there was a carbon plate the works bikes used - not sure if it was the same arrangement as you have made, but looks very similar.
I'm modelling an all in one tank plate (if that's what we'll call it) with the carbon plate that sits between tank and headstock - right now it's in 3mm rubber sheet and when I'm happy with it I'll take a lay up from it (while it's all fitted up to the bike) to make a carbon version.
My home scanner is not working but I'll post up the works bike pics with the plate in place - they show the tank opening all closed up.
I only say this as I've never seen any action shots / complete bike shots with the tank open like a sharks mouth !
Essentially I'm worried about big pieces of rubbish punching through the mesh, or being shredded into pieces that will still cause damage, and would like to think that there's a foam filter in place to halt this.
I guess I was just looking to see if anybody had fitted a foam filter !
My airbox is all fitted up now so I'll post pictures and also post pics of my errrm rubber tank seal.
cheers
