Well it is basically made to make a better seal on the top of the airbox then the rubber stuff on the hood insulation. It does it's job.

Thanks!

Would it be possible to get a custom "path" (using sheets of plastic) from the windshield hole that would draw air directly to the air box?

I mean, installing plastic plates on the bottom & sides of the air box, so that air would be forced to get into the air box?

I think I'm going to try it soon...

Yah why not?! right? Although I think the idea of getting colder air to the box or keeping the box colder is probaly the biggest difference you can make to any intake.

Thanks!!

I will try to make something in the next days... I'll post some pictures of it too...

My next step will be to get some Orciari scoops to draw more air to the air box...

At the risk of causing some pain...let me say this;

With a CAI, such as the Alta (and others of similar design) where air is drawn into the intake mainly via the cowl chamber, only a finite volume of air can pass into the intake inlet opening no matter how large you make the cowl opening, or, no matter how much air you force into the cowl chamber. Also, increasing the velocity of air in that chamber will not reduce the temp. of the air being taken into the engine but elevate it due to increased air molecule activity and friction. Without forcing air from the cowl into the cowl chamber, an open style intake will deliver to our engines all the air it can possible use.

Just look at the factory air intake opening size before a CAI is installed. As small as that opening may seem to you, the engineers and designers of that intake deemed that size opening adequate to feed all the air necessary for our engines. They even took into consideration increasing filter restrictions over time. Yes...that little hole is it!

Okay...take this for example: Imagine you are standing in a 5' by 5' room with 2 open windows and a ceiling fan (fan off). Stand in the middle of your room, open your mouth wide, and draw in a breath...as deep as possible to full capacity. Now...do the same thing with the ceiling fan on high or with a vacuum cleaner (on blow) blowing air in your face. Do you think that in the second instance you are taking any more air into your lungs? Of course not.

Now, don't get me wrong...forced air induction, with proper intake design, has it's place...but our little engines can only take in so much before too much can actually be "too much"!

Do to the hood, and the methods to make the air box shroud, there is a small corner that is exposed. Its not huge, but a hole none the less. With everyone wanting to get as cold of air as possible, the top is a way to seal that corner, add a different look, and hide the filter for those who don't like it. The performance won't be huger by any means, in fact, i don't see it being much at all. But this item isn't supposed to give you 10-12 WHP like the intake by itself does.

Between the top and the SS boxes coming out it is just a way to snaz up our tried and true intake.

Actualy i am surprise someone found this on our site. We haven't told anyone about this at all! But the LV crowd will see it in hand! Along with a couple other new parts!
you gotta anodize to match the hoses and air horn gaskets. blue black and red .

Had it in my hands

IMHO...yep IMHO...

I had the top in my hand and could not understand why it did not look like the photo. sent that top back since it was not the same one I saw the photo of on the web site.

anyway, i cannot tell you how it works. what i saw on the other vehicles that have it looks ok. does what they claim.

I am waiting for the next version from WEBB Motorsports...going to change the whole intake out with what Randy has in mind.

just my Own Opinion....:impatient

The part in bold isn't true.

That is as inaccurate as saying the entire intake design can't be improved on because the BMW engineers always give us the optimal design instead of a design limited by manufacturing and budget concerns.

Bad analogy. Your lungs have a finite capacity and in essence a running motor has an infinite capacity to flow.
If you stated your lungs won't fill faster you would have been closer to the target.
This also fails in another regard. Why do top fuel dragsters run scoops?
To make the maximum amount of air possible available for the engine. They work, it's a proven fact.

I do agree though that the little scoops on the cowls are ineffectual as they are currently implemented.

Too much air is only bad in regards to, too large a cam, heads that flow too much to be effective, too large a throttle body, etc.

Think about it. There is an entire planet of air waiting outside that air filter. There's no such thing as too much air being present at that point.

Obehave,

I respectfully disagree with your disagreement to my statements and I challenge you to prove out your comments with regard to the theory in question that; by adding a cowl scoop to force air into the cowl chamber on an MCS, one will improve the performance of that engine, all other factors being equal and as stated in my previous post. Please, please, please...show me just one proof, in the form of a comparison dyno run or other definitive, conclusive example that this device will, in and of itself, improve engine performance, and I will call you "the king of intake knowledge" and humbly take back everything that I stated in my previous post with a sincere apology to all.

Manufacturer promotional material will not be accepted as fact.

I'm waiting..........

You need to reread what I posted.

I never said or even implied that adding little scoops will improve performance.

As a matter of fact I even stated:

Please read my statements. If I have not made them clear or there is a simple misunderstanding please do ask.


Based on the thrust of your post I am assuming you didn't quite get my meaning(s).


I'm waiting.......

Oooo... I'm telling Mom!

I have the Ociari scoops... and they are strictly for asthetic reasons. I have never believed them capable of trapping or providing any more air than anything else... in fact, I think it's entirely possible they don't help at all because they may prohibit air from flowing out of the engine bay. But I don't care, they look cool.


Game on

Engine bay air is not meant to flow out of those Ben.
Their intent is for inlet air for the HVAC system.

Besides they look like this...

Hmm... now I know why my AC is so minty fresh then.

I just sort of figured with the backwards angled pattern on the stock grill, that was what was intended on some level.

Obehave,

I stand by EVERYTHING I've stated. I do understand your response and indicated that I disagree with your interpretation of my statements.

Please reply with proofs that any of my statements are incorrect.

Substantial facts only please.

A significant reply will be responded to...otherwise this subject is moot.

Cat got your tongue?

Your turn......

I've measured temps in the cowl area at speeds up to 100MPH. They were no more warm at 100 than at 25.
I have measured cowl pressures up to 75MPH and they are so minimal there is no chance of creating measurable compression heat loads.
Believe it or not I could care less

My original refutation of this stands.
Can you prove that this is the optimal inlet size for the MINI? No you can't it's just your opinion no matter how misinformed it may be.
My assertion that it is a compromise comes from having worked in the auto industry and is verified by that fact that moving to another intake design makes more horsepower. If your tiny little inlet were perfect, as you assert, then any other design that attempts to improve on it would fail.

If you don't understand my original refutation then I give up. Finite lung capacity must be the same as a constantly cycling engine. You win

An engine can't "take in too much". It can only take in as much as it can.

Now if in some vague sense you were implying that affecting flow dynamics through bad design would have a negative impact on performance then why didn't you say so. I can't read your mind, I can only read and try to interpret your flawed posts.

The cat will never have my tongue but being bored by technically challenged posters happens quite often.

Obehave,

Just as I thought...bs.

By the way, how did you ever deduct that our engines have an "infinite capacity to flow"? Do you know the definition of the word "infinite"? Go back to the books before you say any more Einstein.

My original post stands.

Ok let me try again.

If you take a deep breath you will at some point stop, correct?
That is a finite flow condition.

An engine, if it continues to run will pump air until it mechanically fails. So yes not truly infinite in the most technical sense of the term but I didn't say it would flow infinitely I said it has the potential to.

Speaking of Einstein.

Two things are infinite: the universe and human stupidity; and I'm not sure about the the universe.

The difference between genius and stupidity is genius has it's limits.


Your original post can stand in all it's towering ignorance for all eternity that doesn't make it or you correct.

You call BS and yet you haven't and I'm sure can't refute anything of what I said.
Your vapid and childish name calling and saying I'm right because I said so clearly defines you as a person and your lack of open mindedness to learn.
I long ago realized that debate with such as you is futile.


I'm fine with agreeing to disagree. You stay ignorant and I'll learn from my betters. ( That of course is not you )

I think you have helped the NAM community a lot with your experience and knowledge. You are on my top best references when it comes to MINI along with Chad, Randy, SpiderX, MSDBrain and Andy! (sure, there are other great MINI guys, such as Alta, MINI-Madness, and other ones!)

Back to the main topic, I am still waiting for my Alta box cover!

nor any RELEVANT friction heating, to complete this correct statement.

since nobody here is bothering to use engineering equations, just try this edison/feynman-like test: with the car windows open (and no ac or heating), take the temperature of the air inside the car with a thermometer. then stick the thermometer out the window at 75 mph and report back the temperature difference.....(if you can even detect one)
