K and N kit fits awesome and works awesome...no idea about actual gains but the turbo def spools quicker. I also break traction even on shifts to third now...when before I only would shifting to second...

Plus it has the cool WHOOSH noise lol...not all the time though so it's not annoying, just addictive.

 

don't suppose you could get a video inside while driving and outside and under the hood. show it off for those of us on the fence?

and any performance differences you can tell? better economy?

 

Just fitted the K&N kit you guys were talking about. much better induction sound when I've got the windows down. You can also now hear the recirc (BOV) between shifts. Fitment was great, instructions were great.. I had it on in fifteen minutes.

Car now spools quicker and I've noticed a 1.2mpg increase in mileage during highway driving and .8 in town.. Plus it looks very much like a factory setup unlike all of the other kits I've seen.

All in all i'm quite happy. Now it's time for an exhaust upgrade and to pitch the intake muffler on the turbos hot side.

 

Agree a video would be great

Tests were already done, I wasn't blowing smoke. Its a test for the R53, the the general theory is the same.

Since were talking MINI's here, there's no reason to compare them to other cars and discuss why other cars respond better to a cold air intake than others. I can go into detail, but I won't since it doesn't pertain to the MINI.

In the end, we are talking about a minimal change in intake air temp, and a minimal power gain.

After running more than a few setups on my 3 MINI's, I would go for a JCW or Dinan intake. The OEM style ones are the best in the long run, I have found. The AGS was an awesome intake, too. I wish the still made an R53 version.

 

Pressure differentials. Any think you can do to increase pre compressor efficiency will increase post compressor efficiency. This includes keeping cooler air around the air filter and keeping a larger air supply around the filter. Look at compound turbo setups in the diesel world and now working their way into the gasoline world. Anything that you do to decrease the effort required by the compressor to reach the desired boost level, the more you decrease the amount of effort that is required by the turbine to spin the compressor wheel. This results in lower shaft speeds to reach x level of boost, less backpressure generated by the turbine housing and wheel, and lower intake temperatures. So while the ecu might actually limit the power output based upon calculations from various sensors, you are still making the work easier for the car to perform.


That being said, it is generally pretty hard to improve upon a factory design unless you have a lot of experience and knowledge about high pressure zones on a vehicle. That is because the factory has wind tunnels and lots of engineers working for them but they also have penny pinchers who will usually take a good design and take it down a few notches to save some money here and there. Putting an open filter in the engine bay is probably one of the dumbest things to do, while pulling from the cowl or utilizing a hood scoop are both really good ideas (look at subaru and older v8 cars).

 

I love all the theory talk without anyone posting actual numbers. Anyone have some dyno runs with before and after?

You also do know that the factory intake is designed to be QUIET and not at all for performance right?

 

How would a dyno show any gains on a part that is designed to get better with speed? As your speed increases and air is moving over the body of the car, you are collecting that air and trapping it around the filter. No dyno in the world is going to give you that. If you want to see if there are true gains, go out and buy a costly gps logging system with a very high sample rate and do a controlled test of acceleration times or if you are an extremely consistant driver, trap speeds would tell the story at a drag strip.

The factory intake was designed to be as quiet as possible while still being efficient and to not choke the turbo. Engineers are not stupid, they have extremely expensive equipment that you and I will probably never have the chance to use, and they know how to tune a pipe, even if that pipe has a bunch of silencers and other b.s. in it. Like all things though, they are forced to work with in boundaries and to make compromises so there will always be room for improvement from the aftermarket.

http://www.max-boost.co.uk/max-boost/intake/intake.htm here is an interesting article with tests and various supporting material about ram air setups.

 

Seriously this thing about sucking hot air from engine bay is getting ridiculous. Most of the intakes out there for the MINI are going to suck in hot air. It is just the nature of the beast. Withou accutally running the filter outside the car you are going to get hot air. There are ram air intakes there are regular intakes I think that there is one cold air but I don't remember who makes it. And its not you are cranking enough power that it matters that you are getting a little hot air. Just live with it and get what ever intake you want

 

Originally I built my own intake and it worked great but it moved around as it just sat on the intake manifold. (similar design to ALTA intake)

I then bought an M7 Super AGS (kinda pricey but it is a custom built box) and that has worked great for the past year. Because it sits horizontal it the filter isn't directly in the path of air coming into the engine so dirt, flies etc etc doesnt build up on the filter like it did on my custom intake.

(Just sold my Cooper S so the M7 intake and Unichip are now for sale)

 

easy.. throw a fan in front of the car like they do for most dyno tuning so you see some airflow through the radiator/intercooler...

13whp for the K&N kit... cant shake a stick at that.

 

I just bought a 2009 Cooper S. Will installing an aftermarket intake system void my warranty?

 

Just about any dealer considers bolt ons like a CAI not a problem. I might ask around about your particular dealer. Some are a little prickly about it

 

Your correct that just about any CAI is basically sucking hot air with one exception, The DoS CAI. Uses cowl induction which has been developed by GM in the 60's and working to this day on NASCAR etc. Concept is that at speed your best airflow is going to come at the base of the windshield vs any hood scoop. Go to the Defenders of Speed website and check it out yourself. Better yet call Clint and he'll walk you through it.

 

did either of you that put this k&n typhoon on get a video for us? i think there were a few of us eagerly awaiting

 

subscribing. not a bad intake. i didnt realize i could get rid of that stock intake tube at the same time !

 

yea i just looked and on ebay you can get it for i think 237$ shipped.

 

lol u have a link?

 

just looked the other day. is it not there? maybe they're that popular :-)

if you want find it lemme know. i have a hook up for them too, i can check to see about sending you one

 

http://cgi.ebay.ca/K-N-TYPHOON-COLD-...#ht_1306wt_941


Here's a link to one...there are 2 or 3 sellers at the moment. I ordered from them and aside from shipping a little slowly...great transaction!

Also it was $226 shipped.

 

ah cool. may i request video in and out and impressions on power/feel mpg? please?

 

Sorry still in the box....too cold to install yet. Materials look very good and the turbo inlet pipe seems very solid. By the later I mean the walls of the aluminum tubing is fairly thick much more than an AEM intake I had on a previous car.

Overall very happy with at the least the quality I see.

 

I have just installed the kit in my 2010 MCS.
First of all I must say that the instruction sheet did not mention that in the new engine the MAF is no longer located whrere the instructions say. However the K&N people did throw an assembly that you put instead of the MAF.
After finishing my job I did enjoy the BOV sound and the throatiness of the engine. I did enjoy every cent I paid for it.
I would highly recommend it, the BOV whistle sound is really addictive.
I will try to show some pics.

 

Mine should be in Monday. !.

 

Hi,
do you happen to know if it is compatible with the JCW strut brace?
Thanks.
