Drivetrain M7 AGS-R Cold Air Intake
#29
Can we see more pics of the underside of the airbox?
#30
Why not? The air is being "rammed" directly into the filter via a scoop. I don't really see that big of a difference between this and a carbed muscle car of old. Both will suck air in just fine on their own, but benefit from cool air having a straight shot to the filter.
#33
thats becuase you don't understand how a turbocharger works...
raming air into a turbo is alot like peeing in the ocean... sure... it makes a differnce... but its pretty minute in the grand scheme of things...
also all of that lovely "cold ram air" is superheated when being compressed in the incredibly HOT turbo. This is why it is most important to have a very efficent intercooler as opposed to a cold air intake... because its more important to control the air that actually enters the engine... than to control the air that enters the turbo.

isellem what you're saying it's true, but it's also true that it's better to have less air restriction and a bigger filtering area, so the turbo can suck a bit better... and if the air it's colder is also better, even if the gain is less than in a NA engine.
I think that with a turbo/supercharged engine the engine scoop is more effective if used for the intercooler, like in the mk1 MCS and the Impreza, but using it for the filter is not a so bad idea, look at all the turbocharged car that run in amateur drag races, without a headlight so the filter can breath thru it, or at the BBR 300hp turbocharged mk1 MCS, with that big filter over the engine behind the scoop, and it's still one of the fastest mini.
Of course in terms of perfomarcance a bigger turbo or a more efficient intercooler is a lot more effective.

When can we see some before/after dyno numbers? I've seen the 4 intakes that are out for the R56 and the only actual numbers I've seen have been from Alta and Gruppe M (although even with those kits, I would like to see before/after WHP numbers - stock and intake only - on the same graph).
I'll be waiting to choose the intake I'll be going with until I see numbers. This one looks great though. I'm hoping it has the numbers to match the looks :0)

Hello...![Smilie](https://www.northamericanmotoring.com/forums/images/smilies/smile.gif)
We will have all the numbers that are expected from us and more.
With that said real world numbers will clarify how effective the
this system is on the road. Airflow is the secret to getting the most
out of the AGS-R but not everything.......

My argument, which i personanlly think you understand and are relating to in the last sentance of your post, is that the time, effort/energy and money spent on this is better spent elsewhere on the engine. i haven't read it for myself yet but i have been told that this system makes about 7hp... now compare that to mike4572s intake for 55 dollars.
or spend that 600 bucks or so and spend it on an intercooler and you will get ALOT more out of it that out of a so called "ram air" system (that admittedly by m7 doesn' really make a big differnce)
#38
the intercooler is more important to giving the car a cool intake charge than any air filter system...it's forced induction after all (ram air is not > the turbo's ability to suck air in). most OEM systems are plenty capable to well beyond stock power levels if a hi-flow filter is put in the stock airbox. it will be nice to see some hard data showing M7 has outdone BMW engineers.

a dyno doesn't begin to approximate real world driving conditions with respect to something like an intake or intercooler. you'd need a proper dyno room setup

Try a 50-90 kph in 2nd or 90-130 in 3rd, or the 0-160 kph... When you have seconds of difference, then you know the money were well spent.

Back to the topic. Any idea if the front part of the intake would melt? And other pics of the components we cant see?

Regarding dyno testing , as this item works primarily with the rush of incoming cool air it's benefits will be harder to detect. I'm not saying it will not get dynoed, we are just not looking for much in that particular type of test.

Thank you for waiting and not making a stink.....![LOL](https://www.northamericanmotoring.com/forums/images/smilies/lol.gif)
The issue is SEMA, yes SEMA is big-time for my composite shop who is taking all the resources from small guys like me, and giving them to the big boys (read Honda, Toyota, and Nissan). But with that said I have been promissed lay-up time next week...so cross your fingers.

so ?
any updates, just got my latest issue of MC2, first page, wham, there it is.
of course I still don't see any numbers or it listed on your site. I don't see the intercooler diverter/funnel on your site either.
nice oem look, the fiberglass unit sounds like a fair price, similar to the ddm unit, but what are you working on to protect it from being cooked by the turbo ?
