haha found it for ya https://www.northamericanmotoring.co...ht=jcampos+AGS

 

Thanks, I never saw this one. I've only heard the AGS clips from the track posted by M7. Is this the 1st version? Any differences?

 

yah its the first version. I dont know if there are any differences....but i would assume that it wouldnt be noticable on video even if there were.

 

M7's heat shield is covers the filter on top, drivers side and rear. I added a aluminum shield inbetween the motor and filter, effectively creating a U shaped enclosure to help guide the air into the intake.

V3.0 will be using CNC aluminum tube instead of rotocast plastic...snap fit. The sound should all be the same from V1 to 3. You trade some in cabin noise entertainment but share more of it with the outside world as the SC sound is much more pronouced and projected ahead of the Mini due to it's frontal location

 

Any chance V3.0 will incorporate something like that?

 

If I'm lucky enough to get hold of a CF heat shield from Peter, he might consider using mine as a pattern for HS V2.0 if enough people request it...

 

Should I put my name down with you or with M7?

 

Give Peter a call

 

Why do you think that's true?

What advantage does it have over let's say.... the DINAN kit?

Just curious.

 

Dianan is another airbox kit (albeit an exclusive kit) that sucks air through the cowl. AGS takes in air through through the front grill where the pressure is highest. It also has the shortest and least restrictive path of air flow compared to other traditional systems...

As to why I think it sucks cold air...I have bugs in the filter Does any other CAI have that problem?

 

I wonder if the force of air pressure is high enough, even at speed to add anything in terms of a ram air effect..? Making sure the path of the air flow is as unrestricted as possible and the amount of air available (under hood vs cowl area vs open to air) both seem more important factors.

If you consider the supercharger to basically be an air pump, would blowing air at it actually speed up the flow of air downstream at all? Or would the speed of the pump completely control the downstream airspeed, effectively slowing down fast moving air and creating a high pressure area on the intake side and leaving the output unchanged?
Interesting questions, to me at least.

 

So it's not necessarily Cold Air Induction you're talking about but more just improved (possibly) air flow.

Now what we need to determine is which delivers the highest density air. Cooler or less restricted.

I think macncheese said years ago there are no real CAI's available for the MINI. I wonder if that's still true.

 

He can have his opinions but I do believe the AGS is the only true CAI...IMO

 

A roots/eaton design SC develops boost due to restrictiion post exit. It doesn't compress air internally like a centrifugal.
So I'd assume( we know where that goes) that throwing a lot of air at the input won't matter once it reaches it's flow capacity at whatever rpm it's running.
Now if the air available is more dense you get something.

 

Is the flow path totally isolated from under hood temps?
I've never seen any in depth pics of the AGS but I've thought that it still allows warm underhood air to enter the system.

I'd think the stock unit fits the CAI description better than the AGS does.
Let's ignore the flow restrictions since we know that's a limitation. And stick to what really fits the CAI concept.

 

Right, this is what I was thinking. As far as flow capacity goes, it would be interesting to know what the maximum flow capacity of the SC is at redline, then see how much the intake/throttle restricts it. I'd be willing to bet that the restriction is actually pretty small.

 

These are the pre SC pressures for a bunch of runs from my IC testing. This is using the HAI. With it and a 60 mm gen 1 M7 throttle body, you can see about an 8%-9% decrease in pre-SC air pressure as you go from about 2000 RPM to red-line. This is a bit less than 1.5 PSI. If you can get rid of this decrease by improving the flow path, you'll get more air out of the SC. It flows (pretty much) a fixed volume of air at SC intake pressure per revolution. Increase that pressure, and you will pump more molecules of air.

I don't have the numbers for stock.... But I did buy a new stock air filter, and a new HAI filter to see what the difference really is. Sometime I'll get around to it. I don't have any other brand of intake to test, but this is the best way to test the intake efficacy.

And the AGS is the only intake system that does anything post TB, so if that is a significant restriction, the other intakes just have to live with it!

Jeeeeesus. You are all way too serious. The energy just burned by this thread could have powered the car to Titan and back!!

Is there really that much difference among the three CIA's listed? For the difference among them, this enthusiast should go for whatever is easiest to install or whichever sound he likes the best. He's not racing the Porches at LeMans in the 60's for top manufacturer's honors, for Cnrist's sake.

Pick what you think looks best, sounds best, and makes your butt dyno sing!! May the farts be with you!

 

Interesting, I wouldn't have thought that there was that much restriction, but I guess all those twists and turns make a difference.
It definitely makes the AGS a lot more attractive if you're going after every last bit of power.
Looking at the pics of the AGS, I can really see why it would make a difference at high rpms where you're seeing the pressure drop. It really is a straight shot through to the SC with no twists or restrictions compared to stock.

These two images illustrate things really well:
AGS
Stock

Certainly makes the AGS look a lot more attractive to me knowing this.

Oh, and markldriskill, it's fun and we're learning. 95% of the time one intake won't be significantly different to another. Most of the differences will only be visible at high rpms once you get past the stock air box. But it's still interesting to see what improvements can be made.

 

I wouldn't call the AGS a better CAI then any of the others. If anything, i'd call it a HAI....

But who cares whether it's hot or cold air....all that matters is how dense it is....

The crimped plastic of the throttle body to SC inlet plenum would cause pretty bad airflow, and the AGS fixes this....what i think might be a good idea is the M7 AGS with a couple of ram pipes to make the air charge a bit cooler, and possible increase the ram-air effect...

At one stage of my MCS's life, i will be de-crimping the throttle body to SC inlet plenum, cos this would be a pretty bad restriction i think, that isn't necessary

 

ditto.

 

Anybody have an idea on how long the K&N airfilter for the HAI is supposed to last?

(edit) Nevermind, I guess it's supposed to be reusable.

 

I've run one for over 100K miles and then sold the vehicle. Last time I saw the guy he was still using it years later.

 

I realize this thread has taken on a life of it's own, but I did make my decision and went with the Helix.

Thanks for all of the feedback and thanks Aaron at OutMotoring!

 

HAI all the way. As the variances between all the intakes are minimal at best, the choice comes down to what camp you sit in and what value you put on looks. you can't really go wrong with any of your choices, just how much money you want to keep in your pocket for future mods!
