Hello there,

I have been doing some research about Air Intakes, and the two most common Intakes i noticed are: K&N Typhoon and Pipercross Viper.

I have swapped my Cooper bonnet to a Cooper S because I am trying to use the air vent for more Air flow.

Which of the above two air intakes will give me better performance when connected to the Air Vent ?

Where do you recommend I should duct the Air to ? Do I need to filter the duct before it enters the Air Intake ?

Your ideas and information are needed.

If you can devise some kind of piping to channel air from the scoop to the Induction kit, then your thats all good!

You shouldn't need to filter it, as the kits have their own filter built in.....maybe a bit of mesh to stop stones etc?

[sa3dos]

Lets say I go with K&N Typhoon,

Is this how it should be done ?

Will I find a difference when I use the extra Air Source than from connecting it to the Front Grill Air source only ??

If I manage to put the Air Intake Filter in a sealed box, would that Improve the Throtty Noise and Increase Performance ?

[sa3dos]

I also found another good project plan using BMP/ProMINI Cooper Intake

Since it comes with metal housing, i can just cut another circle in the housing from one side and connect the tube which is coming from the scoop to it, see example in the attached picture.

The only concern is, after doing researches (pasted on my other thread: Intake Comparision), i noticed that Monster Force creates more Aggresive noise than the BMP/ProMINI intake, and aggresive noise is something I am looking for.

But with more air flowing into the Air Intake, does that mean More Noise ? or noise has to do with the filter brand it self, not how much air is coming to it ?

You're find that the casing is used to protect the CAI from flooding as it's position is usually lower then the OEM intake. The K&N typhoon is a CAI build and is designed to draw air outside the engine compartment. Having air scoops wont improve ur CAI as the filter itself is sufficient to draw air from the front air vents. (the air scoop is for the intercooler on the S, so i dont see a point in changing hoods) Noise is the resonance of the air flowing from the filter through the accordian tube into the throttle body. More noise means absolutely nothing. No matter what intake you go with, there is alwasy considerable noise increase under WOT or semi open throttle.

in conclusion, modifying the air scoop wont do anything as the CAI is designed to operate without the help external air flow. Keep in the mind the amount of air drawn from the CAI is decided by the gas pedal. More gas = More air. The throttle body is in charge of decideding how much air is to enter the combustion chamber. By installing CAI you are only improving the rate at which air is drawn. So if your engine can only handle 10 molecules of air under WOT, there is no point having a CAI that can pump 20 molecules of air (just made up these numbers). The CAI is a suction devise, if i was to place a fan infront of your face, would u be able to breathe better. Same logics.

Just my 2c

I agree with you word in some parts, but what about the formula which states:

More Air = More Power ? ( Or does that only apply to bigger throttle body as its the only device that controls how much air to enter ) What if I get a bigger throttle body ? does it exist for the cooper ?

Btw, I already have the Cooper S hood installed already since few months, so there is no turn back now because my Cooper Hood was already sold.

Actually, its not necessarily more air, but colder, better quality air is important

Most MINI tuners sell Cooper throttle bodies like.............

So more regular air flowing into the Air Intake will not make any difference.

what about:

As I press the gas pedal hard to accelerate faster, the throttle body will open up wider expecting to suck in more Air delivering it to the Combustion chamber, what if the amount of Air around the CAI is insufficient, and thus you lose power !!

by adding extra air source ( from the scoop ), I make sure that the CAI has enough air surrounding it, afterwards, when Throttle opens up to suck in air, it will suck without limitation to the quantity of air around it.

Unless you are saying that with Front Grill air source, there is Always enough air ?

my 2cents is that yes - there's probably already more available air, i.e. you wouldn't need more even with a larger throttle body. Re: your quest for more throatier noise, you may have reads adverts or posts to that effect regarding some of the CAI for the S but I can attest that the increased noise levels are generally associated with replacing the enclosed OEM air box with a more open design - allowing more of the supercharger whine to be audible.

go for the viper as half of it is already done for you and it's louder

the scoop should hopefully give you colder air more of the time as well

what would be really special is a throttle body conversion that uttilises the scoop in the S bonnet! then we'd be talkin noise and some impressive power gains

[wedi_mynd]

Why not just get a Cooper 'S' ?

got one

don't forget some people can't insure the cooper s, can't afford one, plus a million and one other reasons, so just getting a cooper s might not be that easy

[sa3dos]

I guess i am not going to use the Hood scoop mod for now.

Well the reason why I didnt go with a Cooper S, because I was planning to add a Turbo instead, so I thought the Supercharger will be hastle to sell.

I am still going to add a turbo, i just dont know when, i am still reading all about it, and am sure the Hood Scoop that i have will be usefull for turbo.

Thanks a lot for the info everyone

[danbanger]

Good luck with your plans, I'm sure many MC owners will be listening if you ever get around to doing your turbo project!

If i were you I would fit the S hood and rig up some ducting towards your airfilter. It isnt necessarily more air that you need, the same volume of air but at a colder charge will require more fuel to burn it, hence more power.
If you can provide the filter with a constant supply of colder air, then you will see a power increase, obviously the faster you go the colder it will get so you may not notice much difference from stand still, but when your rolling the pick up should improve.

Go on fit it, you know you want to!!!!!

[A13EX F Cooper S]

you want to use the vent in the bonnet as a ram air setup.

forced air through the vent should be piped to a "sealed" box with the filter inside it.

just bear in mind when setting it up that a lot of water can come through the vent in the bonnet so do not use a completley sealed box and try and make the air intake come into the sealed box below the air filter with a drain under the entry for the water to go.

[Damo]

You could get a Pipercross Viper, then modify the supplied piping to go to the Bonnet Vent?:

A13EX F Cooper S:
sealed box, wouldn't that decrease the filter noise ?

Damo:
getting the Pipercross Viper intake is one idea, and the project I planned for the ProMini intake (picture above) is another idea too, but as A13EX F said, I would face water problems if I connect tubes without a box to drain any Rain or Wash water.

Black Works:
The S hood is already installed, and your idea of using the vent is what am planning, except that, after reading about Air Intakes, and like word quoted above:

"The throttle body is in charge of decideding how much air is to enter the combustion chamber. By installing CAI you are only improving the rate at which air is drawn. So if your engine can only handle 10 molecules of air under WOT, there is no point having a CAI that can pump 20 molecules of air (just made up these numbers). The CAI is a suction devise, if i was to place a fan infront of your face, would u be able to breathe better. Same logics."

Plus; ducting a tube from the hood vent is not easy if you actually think about it, because it requires custom built box, so when I decide to go for it, it better give me better results or it will be a complete waste of time and money
