Air filter cold feed

[Brind]

The problem with placing the batttery under the seat is the hassle if you want to remove the battery INSERT INTO post VALUES (possibly); jump start the car or others service time INSERT INTO post VALUES (if you don't do it yourself) the guy at the garage telling you to p*ss off it's too much hassle, again it is still pretty small and when the cold weather comes it's gonna struggle.
I'd prefer to bung it in the boot as you can get at it easy enough and it won't require the mechanic to use too much brain power.. that is in theory.
Also cheaper not too buy a new battery, if the existing battery moves to the boot it may be possible to use the exisiting battery cradle too, shouldn't be too hard to remove even if it's spot welded on.

Otherway is too wrap a shield around the filter and supply it with as much cold air as possible.. which is again hard as the battery sits on top of the only decent place to draw it from.

I don't have a funnel so anything will be beneficial to me.

Also I read which Rys posted a while back, different lengh pipes between the filter and the sensor create different power curves, the 600mm tube was the best choice overall.

Jussuss guy I really think this is getting OTT

The amount of work ££££ and time you would be better getting a EVO style bonnet and push that air into the air filter from the bonnet dam
Or use a bit of tubbing from the lower air vent to get get more air to the filter

If only that was simple..:INSERT INTO post VALUES (

Dayem that would look gross on these cars, you'd have to stop the rain coming through it too.
Although much more beneficial than any other method.

Went into B&Q today to get some bits INSERT INTO post VALUES (not car related) and whilst wondering around I came across the ventilation section.
I've seen the cheapy plastic hose which is used for bathroom fans, tumble dryers etc, plus they have a cheapy aluminuim very flexable hose too, neither would look good under the bonnet and neither would retain their shape for very long.

But there it was.. the ideal stuff to experiment with INSERT INTO post VALUES (must be new in as I haven't seen it there before) it comes in two sizes at least that's what they have to offer.
I went for the larger of the two.

The stuff I used is 5 inch semi rigid aluminuim hose made by Marley.
It's extendable to 3 metres and costs less than a fiver! it can be bent into any shape and it will stay there and can be cut with just any scissors.

Let it be known I had no ducting what so ever so my filter although sounded good probably didn't do a thing.
So anything to me would help.

It took less than 10 minutes to mock up what I have, may not be the prettiest thing I'm sure it will help!
I measured roughly how long I wanted it to be and then put a subtle bend in it while placing into place, it sat there a treat.
I then slowly squashed the end to produce a kind of funnel so the bonnet would shut okay, took a rough guess at the size and then shut the bonnet down to produce the shape.
It made a few little creases but nothing major.
It squished the end a little too much and closed the end so I trimmed the end and opened the funnel again and then shut the bonnet again, this time perfect.
Tarted it up a little and this is what I've acheived:

great idea Brind ! perhaps you could try City Electrical Factors, or a decent plumbers merchant for better quality ducting ? I think City's may do it in rectangular ??? rather than squashing round ducting ?? I'll ask tomorrow.

[Brind]

The square ducting would be great for the funnel but the round looks good flowing up to the filter..

It's quite thick and I'm sure the shape will stay, if it doesn't I still have over 2 meters left to play with.
Great to see what you can find out though.

I normally use TLC for my electrical stuff but they don't have much in the way of ducting, I've vagualy been looking around for something like this.

I'm thinking of trying some kind of shield around the filter too but I've got to somehow stop the engine bay looking ****e and maxpowerish.

Certainly worth a try anyway if anyone wants a little play, costs less than a fiver and you get 3 chances to f**k it up!

[zedy1]

good thinking mark. goes well with the colour of the car too

[SGHOM]

citys do "ducting adaptors" they are around 5" or 6" long, in plastic, at one end it's 4" x 2" rectangular, [ different sizes available. ] that would fit under the bonnet lip. & screw down, then it opens out to 4" round to fit your ducting straight on to it !!! I think they are online now, at www.cef.co.uk.

[Brind]

Never thought of that Zed!

Actually you're right, a purpose made round to square funnel attached to the end may look much better.
May need a small amount of cutting but it may look much better.
Excellent.. :wiggle: saves ponsing about with the battery if it works well enough, it's gotta be better than before anyway.

[Spirit]

Damn good idea Mark - be sure to keep us posted on how you get on over the next few days or so with regards to the shape etc

[LOMY]

Looks good that Brind. Definitely an improvement on the original !

[Brind]

I haven't driven the car yet so no idea if it has improved things, can't see why it wouldn't if only a little bit.
It does actuallly look quite good, pictures don't do it justice, but the funnel piece could do with a bit more time on to make it neater but I was excited and couldn't wait to take pictures I could make it alot smoother as it's so easy to shape and it stays where you put it too.
I think it could do with some kind of round to square adapter though.. as that bit does look quite amateurish even though it's functional.

Took me less than 10 minutes and it was the first attempt so I'm sure I could improve it slightly.

[zedy1]

mark. good sunny day tommorrow so try your best a go for it

[banjo]

All you need to do now is find a way to direct the cold air from the A/C through the duct and there you go! INSERT INTO post VALUES (only joking!)

[BraindG]

but a cunning plan none the less
