View Full Version : Which Filter ?
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.
Mat.
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.
Im not too sure really Brun, it would be worth a try if you could get hold of a cheap open filter and do some comparisons, however the pressure created in the air box, when sucking the air through the pipe might be a good thing, im not too sure pal!
Im gonna buy a cheap reno paper filter and see how that goes until I can clean my ITG one, wonder if it will make a difference?

I saw a comparison of paper and cottom once. Both produced the same bhp, but once old the paper one lost more power, wheras the cotton one continued to perform. Id say paper is as good as cotton, but you have to change it more. But then they are dirt cheap so who cares.
The K&N on my valver is massive, bigger than other 16v K&N filters i've seen. It is a proper 16v one though as I bought it.
I notice the car feels flat in summer like its being choked. Closed induction is the way forwatd for performance. Open induction for the awesome noise they make.

I've got a 57i on mine, but i've also got one on my 19 which i've never rated as being any good. I've bought a hillpower one for the Williams, but still not got round to fitting it. Is it worth fitting? Or is there something better i could get with the money i'd get from selling the hp filter? (its the Ramair filter in a semi-enclosed housing)
If you sell the HP one in enclosure (half) i'll be interested in buying it. Is the heat/shield enclosure blue? Its just the one which covers bottom half of filter isn't it?

Yeah thats the one. Well if there is something better for the money, then i'd sell it, if not, then i'll keep it.
If i have a change of heart, i'll let you have first refusal Brun
The hillpower kit that relocates the filter to the passengers scuttle would be the one to go for...although their heatshielded one you have is fairly good.
I had std paper, k&n replacment, k&n cone, hp heatshielded and the airbox was still the best IMO
ive got the ball rolling on a valver/willy ITG Maxogen !
You made of money BRUN :shock:
ITG panel filter will do the job and be about 10 times cheaper!!!!
i thought you of all people would want one....its carbon !
Why do open air induction kits make such a nice noise, what is it that makes it make that noise??
well i think a normal filter would make some noise, but its because its in a box that you dont hear it much

If you want power increases just copy the rally car designs and modify the bonnet to provide cold air, as Nick Hill has done on his own car.
If you dont want to modify the bonnet, then a paper filter in an oe box will be as good as anything on the market (unless wet dirty, in which case a paper filter will lose power that a cotton one wont).
Well you heard my ITG at the CostCo meet, has quite a bark lol Im going back to my airbox....All tho the king dong does sound sick! :twisted: The Airbox felt better low down???
Need to do some testing :roll:

Trouble is with filters people replace a dirty paper one with a clean cotton one and think its the filter thats provided the power increase.
The other day i replaced my dirty cotton one with a clean paper one. Guess what? The car was more responsive.
Funny that. :roll:
so you use an ITG aswell Winston, so does Danny and he said the quality was very good
Yer it seemed alright, had rubber edges, foam filter and a bit of oil on it to stick all the dirt to, seemed a good enought buy at £30! Gonna try the reno paper one soon though!
dont suppose you still have the part number of which one you ordered mate ?
because the one Winston has, and from what the fella at ITG was sayin to me yesterday, it doesnt have any rubber to it, its just foam

Whats the BMC CDA filter like? And whats a good price to pay for one? I've got a couple of mates who've got them on their V6's, but not sure what they're like on the Williams. (still not got round to fitting my hp one yet!)
this is quite tempting....

The trouble with the bmc is plubing it in, there just isnt enough room. Can be fitted facing backwords but thats far from ideal.

Cheers Jan, i was hoping that not to many people owuld see that lol
Never mind, is it worth going for then?

i might have a ktec viper for sale soon if any1 is interested

If you want proven and tested results, Nick Hills IK relocation to the scuttle panel WILL give power gains. £300 is expensive, but its developed from race experience and the complex situation of heat build up in the Williams / Valver bay requires a cpmplex solution.

king thought it was only about 200??
CK01 Full kit with bottle £200.00 plus vat Retail
CK02 Induction kit only £180.00 plus vat Retail
Fitting of the kit in our workshop £35.00 plus vat.
Went to rolling road today with a mate and his fester rs turbo which has a piper cross cone filter the operator laughed at it, drawing hot air from all over the engine bay and forcing it into combustion chamber is not good the colder and denser the air the better performance cone filters are okay if you want induction roar but enclosed air boxes with cool air feed are the way to go manufacturers spend millinons developing engines to get optimum performance then the likes of k&n claim to increase horsepower which is bollocks incidentally the works peugot 306 uses a cylinder type cone which is totally encased in a carbon fibre chamber isolating heat from bay but who can afford that not me anyway so ill stick with standard.

I have been thinking for a while that I may make one for the rally car. I can see more scoops finding there way onto the Clio's bonnet. :twisted:
i'll be taking feeds from the blanking plates next to each foggy when i can be arsed.
