If you look where the cowl vent is the hood covers it and there is only that tiny slit along the top of entire width of the hood where the air is being pulled in. I don't think that while at any speed anything will get sucked in and while sitting i doubt much of anything gets in there to begin with.
I was looking at this last night, I'm thinking of getting one my self too.

 

Dos does not suck up water,i should know i live in florida .

 

Nice call james i mentioned your name today.. thank you so much for your help.. maybe one day we could drive side by side ... if i could keep up

ill try sending you a pm for my next up grade... ty with all due respect

 

car sat outside in a monsoon for the past 2 days without any problem

tell clint james hunt sent you

 

tell clint james hunt sent you. no i do not work for dos

 

yes, but inversely. Which would mean that the low velocity zone at the base of the windscreen is also a high pressure zone

BTW DOS CAI rocks. Only real CAI (imo), and Clint is the best vendor I've ever dealt with (along with Dustin Etheridge of AutoXCooper)

 

thanks for the info

 

Clint sells a hydrophobic cover for the filter if you are really worried about the rain. I asked and he flat out told me not to buy it. Said it wasn't necessary at all. I love the DoS intake. Buy it and you will not be disapointed. It sounds great!

 

here's an article with real world testing:

showing that the nose of the car is FAR superior to the base of the windscreen... (in achieving positive intake pressure)

and the nose of the car being much better place for an intake:

http://autospeed.com.au/cms/title_Si...3/article.html

 

Yes, there are definite benefits to pulling air from the nose of the car, that's why it's good to never eliminate that option. However, if you'll notice in the images below from the article they're pointing to vertical surfaces on the front of the car. MINI already has an inlet in a high pressure area at the front of the car (the grille) that works well and should not be ignored. The highest pressure areas are also the ones that are most prone to allowing an engine to hydrolock when you drive through a large puddle or are driving your car in a driving rain. Just like the author of the article, I caution against using this approach on your daily driver.




In the pic below, notice the areas in purple. These are transition areas for airflow into a low pressure zone. Because the R56 has a more gradual contour than the Mercedes shown below from the vertical surfaces at the front of the car and over the top of the bonnet, this transition zone is becomes dramatic than the car shown below. The hood scoop on the R56 is also set back a bit from the front of the car and is already in that transition zone back to low pressure. If the hood scoop was shaped more like a NACA duct for spec Miata or similar, you might be able to justify that you can get a huge amount of airflow from this area, but this illustration is not adding a huge amount of water to the concept of the factory hood scoop as a huge win for induction. (I really want to test and see ASAP, but prep for AMVIV won't allow for that at present.)



As a final note, I also noticed that author also touts the benefits of using a closed CAI system.

Thanks again for sharing these articles. I've been saving them for testing and marketing ideas for over the spring & summer.

great post send mine out asap....

 

Nice article for sure.

The real benefit to the DOS system that I see is that it offers a simple yet very effective way to work within the packaging restraints that our cars offer. I mean there is no relocation of anything and all you have to do is replace a bulk head panel and it provides great results.

That being said, I am willing to bet there is a market for a kit that involves relocating the overflow bottle and the maf.

 

otto

give up. opinions are like buttholes, everyone has one !

 

Well this was a dumb response. Clint even acknowledged that the front of the car is a great area to get air from.

You should give up on the tough guy know-it-all attitude.

 

Otto always has these i know everything and i will prove you wrong posts and on this it looks like otto is trying to discredit a great product and a great vendor .If Otto wants to have fun and be constructive his effort should be directed towards vendors that sell Junk,For a R56 turbo my opinion is that all you need is a lowtemp air source, airflow and air pressure are not as important on a 1.6 turbo engine that spins 7500 rpm compared to my susperstock/A Dragcar with a 7 liter that turns 8500 rpm and runs low 8s at over 160mph .

Clint makes a quality product and provides 1st class service.

 

ya'll can go round and round with these intakes but I'm pulling my DDM and installing a JCW stock intake back on.

I don't believe any of these intakes make a big enough difference to justify paying some of the ridiculous amounts they are charging for them.

The only reason I didn't install a JCW the first time is because I had an M7 cross bar. Now that M7 is suppose to be making one that works with the JCW, I'm going back.

What I like about the DoS intake is that it takes advantage of TWO pressure zones - the standard intake in the front and the lower (but still effective) zone near the windscreen. Is it better than expanding or adding intakes in the front, high-pressure zones? Probably not, but given how packed the engine compartment is I don't see a way you could accomplish that feat.

Sometimes the best engineering happens when you work within your systems' constraints, rather than reinventing the system itself.

 

It's pretty obvious to me. It uses the factory pipe in conjunction with the filter through the cowl, completely eliminating hot engine air in the intake. What's there to argue about?

Not to mention that it sounds great too, and Clint is a great guy, who provides great customer service. I emailed him this morning while I was installing the intake, to ask if the filter was pre-oiled. I had an answer before I was done. That means ALOT to me. Many companies forget about these things after a while...

 

I would bet that a new coldair pickup point by Dos is in the near future !

 

Now there's a man who knows what's up!

 

Word...although, based on my scan guage, I do produce lower temps with my setup as opposed to my normal stock, non JCW intake. Enough to say I make 10 extra HP because of it...false. However, it does improve air flow and keeps my gas mileage at a nice number during these safe, slow driving winter months.

It did give me at most an extra 6-8 HP (based on dyno runs I did back when that was my only mod), not that its a huge number and definitely not enought to justify what I paid for mine.

Live and you learn...

 

I second that. There are many out there that give you noise, but I'm not convinced of the power gains either.

 

dude!!

I never started this thread with a clint bashing post?

I just wanted to start a discussion..

in fact i give huge props to Clint for actually posting in here and defending his product!

I never said it was bad did I?

i just wanted to figure out what the BEST place to draw air from would be..

for years ppl were using the fender well to draw cold air from.. and this turned out to be a big myth... the wheel well is a low pressure area and a terrible place to draw air from...



What I don't like seeing.. is ppl that are band wagoners just repeating what they see or heard.. with no proof to back it up or knowledge of why...


I also stated earlier in the thread.. that I like to play devils advocate..

I don't have to be right or wrong.. but if my questions and challenging the norm gets answers and info out.. then I see it only as a win win situation..

Clint is a stand up guy who stands behind his product... in his replies he didn't seem offended.. and replied in a professional and curtious way

the fact that he has a "defense" for his product means he knows what he's talking about and is knowledgeable on the subject..

look at the ALTA products.. not to long ago they were the bees knees.. now ppl talk about avoiding them..

or look at boost tubes and hard intaks etc.. going on about how much diff they make..

when in fact they didn't...


perhaps people got the wrong Idea when I opened this thread..

it started as a discussion about CAI VS all.. and ended up off topic
into a DOS intake > * discussion..

 

at least you agree that friends don't let friends buy alta

I have tried almost every intake that is marketed for minis on our shop dyno and only 3 made any noticable gain
1 dos (biggest gain)
2 gruppe m
3 ddm race intake

all the rest just suxed hot air

 

this is exactly what I'm trying to figure out...

since our engine is so weedy and asthmatic..

u can fall into 2 schools of thought

Big baller fancy intake to try and squeeze out every ounce u can get

or

mushroom on a stick for cheap "since it wont make much diff on a turbo car anyway"


that is what this whole thread is about!
