looks very nice. It also looks not to be installed completely, but is just resting on the intercooler for the pic, right?

 

I know you don't want an answer from be but anyway, I think they couldn't take a pic of the whole system if it were installed unless the bumper was off.
BTW its not installed completely (I know I'm a smart a$$)

 

One step closer to a finished product....

Here's the system completely installed with the heat shield in place.

Air Gain System...

 

How long until we get some numbers?

It will be interesting to see how the difference in location affects the numbers.

 

Now that I see the AGS installed, it looks like it will get some cool ram air as well .

 

it looks like hai in theory... relocating the filter obiviously have shown some improvement as shown by the hai

i'd want to wait till the numbers show up... till then an intake is an intake.. sorry to those who make the air gain as a religion...:smile:

 

What about water... any kind of bypass to prevent hydrolock, or any way to keep the filter from getting soaked?

(Hard to tell from the pic, but it looks like it's an inch or two away from the inlet in the front for the air to flow for the stock intake, which would mean almost a direct hit for any rain you drive through)

 

I would like to answer some of the questions...

1. It's like a HAI.... The answer is simple it's not there's not one part that
compares to the HAI, we relocated the TB, the inlet tube is new and has none
of the power robbing curves and restrictions, the filter media is huge and
it will allow crank case ventilation. and finally it's not subjected hot air as the
heat shield is functional.


2. hydrolock... Unless you drive thru 3 feet of standing water, there's no way to hydrolock during a rain storm or heavy downfall. We will have a rain shield
available (optional) if you feel that a rain soaked filter element is a problem.

sincerely

From what I've seen mentioned regarding the beneficial characteristics of other induction systems, this is what I've noted:

1. Go to a higher flow filter element (the sole solution of many aftermkt units).

2. Allow for more cooler air to be available at the point of entry (the Alta made this a strong selling point).

3. Widen or enlarge the stock air path, namely to the TB (I recall a couple that do address this aspect).

4. Make the inside surface of the air path smoother for improved flow dynamics (I believe the same couple claim this as well).

5. Eliminate flow-robbing bends, and shorten the air flow path (an emphasis of the HAI).

==========
From my readings here on NAM, the above are all contributors in making for performance gains.

The AGS takes into consideration all of the above! It also addresses a path (TB to SC) that was previously un-touched, but by a few of us with a Dremel . I believe the flow increase over the stock runner was 10% (figure provided earlier). And with the rest of pluming distance and bends eliminated, and a cool air feed in front of the filter, this seems very well-conceived.

I'd like to see some power figures too, but mostly with a mod'd MCS that can really take advantage of this increased air supply...

 

One can design ressonant systems as well. The air is modulated, or pulsed. This frequency can be used to advantage (ever hear the term tuned intake?) to increase air flow at certain RPMs.....

Also, while it may look like a ram effect, for the sealing and the like, you can neglect any significan't effect. But it will have cold air from the original vent.....

Windmeup.... for all the time I've had an HAI, and we've had some pretty sever rain, there has never been a problem with water. An I have no rain baffle.

Looks very nice. Have you logged a measurable difference in air temps with the heat shield and without?

 

Peter,
Put your animosity aside and for a minute and embrace the HAI. Its your friend. You mounted a filter on the throttle body eliminating all the upstream restrictions. You expanded the filters XS area giving it more room to breath. You used the largest filter your cram into the area you had to work with. Thats the exact same philosophy. You've got a few more bells and whistles downstream that make what you have a sellable product versus our silly thread that says "buy this part number and stick on your TB." Kudos to you for taking the HAI a step further... Now lets see some numbers proving its better.

As an FYI,

My last car had a CAI located betwen the lower front fender liner and front bumper - somewhere about 12" from ground to the tope of the filter. Never had a problem so long as I was smart about deep puddles. Different car yes, but If you're careful...

One can design ressonant systems as well. The air is modulated, or pulsed. This frequency can be used to advantage (ever hear the term tuned intake?) to increase air flow at certain RPMs.....
The above mentioned CAI took advantage of resonance tuning producing and astounding 12-15whp and 8-10lbft torque spike at approx. 5,300 rpms. This was a good thing for this application; the motor was a 1.6 liter Honda DOHC with VTEC. VTEC operation came into play at 5,600rpms. The power spike was very helpful as power began to drop off ever so slightly just before VTEC operation. Actually, the drama experienced at 5,600rpms was sort of removed by this spike - no more on/off switch if you will.

 

Peter, any news on availability??

Looks good

 

Matt, while I've heard of "tuned intakes" (and exhausts) previously, that is not something I've come across in the offerings for the MINI thus far. I was trying to share the attributes of the choices we've had available, and how the AGS compares.

Actually, that brings-up a good point. I thought I read somewhere (maybe here on NAM) that a tuned intake is primarily for NA cars, and that the goal for us would be to simply feed the SC an abundant supply of air. Since there is a SC involved that is compressing or displacing air (thanks mac, I'm learning ), it does not seem to make sense to do such delicate tuning before this violent activity. Remind you, I'm just speaking from what appears to be logic for me...

With this filter in a similar location as the HAI, it would seem that water shouldn't be a issue. I recall a fairly lengthy discussion on this topic in the HAI thread. Either way, it sounds like M7 will provide something for those who want some re-assurance...

 

Exactly. For forced induction cars, you just need to get as much air as possible to the super/turbo charger. Lambo used a tuned intake to give a "supercharged" effect on some of it's NA cars.

 

The K&N kit is a tuned length intake. If you notice their metal tube isnt the same length as rubber tube it replaces. That length was probably selected after testing of different lengths to produce power in a certain RPM range.

Supercharger induction is cyclical, just like NA cylinder head induction.

Thanks mac, I was not aware that the K&N did that, and that such tuning was doable or desirable with a SC in the flow path...

 

Great info guys

 

I just hope that the AGS outpowers the HAI by alot - otherwise the cost would keep me away. hmm - few hundred dollars vs 26 bucks? Lets do the math on that

Just had a bit of time to do some research and reading... A tuned length has the goal to aid in adding pressure. It tries to replicate what the SC does, which of course we already have. This is due to the aformentiond resonance, and apparently, more exactly, the Helmholtz Resonance:

http://en.wikipedia.org/wiki/VLIM

http://www.phys.unsw.edu.au/~jw/Helmholtz.html

And after reading this one, I'd say it's not something highly important, especially with forced induction:

http://auto.howstuffworks.com/question517.htm

 

I guess that depends on what "a lot" means to one. Being that the HAI utilizes the stock TB/SC runner, there is a 10% gain right there alone. For one trying to eliminate as many flow restrictions as possible, that's significant...

When I got my TB from Peter a year and a half ago, he recognized the short-comings in the stock runner and recommended that I Dremel-out any excess material around the perimeter of the openning. He said that it 's not likely to do much, but it's something; and that he would try to address this more completely later. The AGS was born from here, up, not from the stock location, or from the HAI downward...

 

Why are you quoting numbers?

 

Well, because I can.

I believe that figure was provided earlier during some testing. Since that is a stock piece, and one that all other systems have utilized, Peter shared how it compares to the AGS replacement.
