I read a report recently(I forget where) that the "cone" filter induction kits are a waste of space and don't really help the car. From seeing pictures of coopers with them, they seem to sit in a position that will only suck in warm engine bay air and don't seem to have a cold air feed. Makes sense I guess. I've seen modified cars that have the filter just behind the front grill so that would work but I don't see how the mini one will benefit.

I'm not really technically minded so any advice would be grand considering that they are expensive to buy.

The JCC cars use a modification to the air path to allow more cool air to get to them - Restrcited by regs but sure with some imagination and tubing a good job can be done at very little cost

[supercuper]

The Radiator is in the way of the front grill so no cold air can get in there and I'm not going to cut a hole in the front. I don't see how cold can get to the intake.

[Racer]

The existing intake (centre above radiator) on main radiator panel is reasonably well place air can be directed from here straight to the filter it's not ideal but you should see some performance improvements

You can see the piping here

Hope that helps

my pipercross kit came with a cold air pipe to do with as one thought fit. I ended up attaching it or the pipe that Racer shows, using the existing inlet found above the radiator.

I think i have some pics in my gallery....

edit.....

nope, there are pictures there, but the piping routing shown has changed now, and is is no longer ducted like shown. there is a picture of the kit tho.

I have noticed a load of bugs on the back of the filter, where the pipe duct exits on to the filter, therefore it must be working and pulling air in.

Additionally you can make extra intake from the left and right side of the top panel in the same way as the centre - In JCC cars they are not 'linked' to the piping but no reason why you couldn't

You can see the area on the left of this picture

If the kit works, great! I just don't really understand how it works. In the stock filter, Air comes through the top of the radiator through a pipe, into the filter and into the engine. So how does the Induction kit differ, The cone and larger pipe attach to the engine right, so does the air blow through the hole above the radiator and on to the cone? How does this improve performance?

Do you mean in these areas?

Yes - On some JCC cars and probably ALL 2003 Trophy cars you'll see these 'cut-out' but if you don't have regs to worry about you can run additional air from them straight to the filter either linking with exisitng centre pipe or as three individual pipes

in theory, supercuper,...by pulling more dense air into the engine, performance should increase.

we have all listened to motorsport commentators harping on about how with a bit of rain in the air and an overcast day the cars will perform better.

for dense read cool/ cold. in my XR2i, the filter box originally sucked air straight from the engine itself. ok, so the car has to have air/ petrol to work, but that never meant to say that the maunfacturers had to make it work the best....

(am i on the right path here, by the way guys?)

anyway, when i took the box out and replaced it with the induction kit (K&N), the 'hot air' piping was disgarded, and a piece of cold ducting pipe was inserted into the grill.
with the engine on you can hear a very, very audible 'suck', almost like the noise mad maxs scoop used to make!! therefore the amount of hot air getting into the system is seriously reduced because the cold air pipe is directed over the filter which then gobbles it all up.

now, if there isnt a pipe for physically taking cold air from outside directly to the filter, im not sure where the benefits would be.....

looks nice though

my father always used to say that it was all about breathing. if the car can breath in as efficently as possible, and then get rid of it out the other end as efficently as possible, then your on to a winner.
seems to work,....

but then, every day is a learning day.....

My mate on his Fiesta had a K&N filter but he was lazy and had put it on resting over the bottom of the airbox. Ok on the road this seemed to work but when he had it rolling roaded the car was actually down on power 86bhp instead of 90. While it was being rolling roaded they put the top of the airbox back on with a K&N pannel and it actually made more power than standard. The K&N induction Kit was then put back on with the proper cold air ducting and the car made 98bhp istead of 90, with the pannel in it made 93.

So the induction kit does make a difference. Great. Now correct me if I'm wrong, the pipe from the top of the radiator, the original pipe to the stock filter box will also feed the induction kit cool air from outside.

[Loui]

Supercuper the pipe for the air box should feed the induction kit with cold air but as my friend found out it does not always work like that, but in the case of the mini i should say it will work as the filter sits next to the end of the pipe which feeds the cold air in

[Dom]

I've angled my induction kit towards the pipe so I think it gets cold air.

When I had a green induction kit for a saxo vts on there, it was in a different place slightly, and could get hot to the touch

I still put out 116.5 bhp with it though.

Since I've put on an induction kit designed for the mini, it never gets hot.
