Which Filter ?

[BRUN]

i know most people seem to recommend the OE box

but whats your views on the best filter for the valver/williams

would a huge cone filter not gain over an enclosed system once your movin ?

the Green induction kit for these cars uses a HUGE filter, way bigger than the K&N

currently ive got a Pipercross element in the OE box, ive got a K&N element that i could fit but it needs cleaning...

ive seen it said that a lot of the race cars use the OE box, but isnt that simply because they have to ?

most WRC cars use a cone filter from what ive seen, the 206 one definitely does

Depends how your car is set-up really.
I tested a standard airbox against a 57i on my Red one at York and the times were better with the 57i, but the Williams i was swapping with performed better with the standard box, my 16v was obviously not standard whereas the willy was.

well its got 270 cams and chip...

i think i might benefit from the extra airflow, even if its warmer air, not sure though

like i said, its a lot bigger than the K&N kit



its one of the biggest filters ive seen fitted to a car, and Green do have pretty good kits for French cars

what you need to do is fabricate a heatsheild over and around that filter and give it some decent air feeds, none restrictive... no good getting all that heat from directly behind the rad.

also, whats the surface area of that filter??? im sure the std box filter looks like its got a large surface area.

well, Green make a heatshield which ive bought before, on the 5GTT engine, when i had that, i had a BMC CDA, and i changed to an induction kit with the heat shield and didnt notice any loss in performance

pretty damn big, but your right, the OE filter isnt exactly small either...

Not sure the surface area of a cone filter is any bigger than a panel filter in the oe box.


So whether it would suck in more air i doubt it.
