Cobb cold air box for SRI

[whitey4311]

LOL, the same as a CAI but the filter just isnt down there. The coolest air is right where they put that snake thingy and right where the CAI's sit. They get outside air from via the grill so it cant get any better then that.

That idea seems pretty lame since I dont see any way air will be drawn up from that section unless that box they made is air tight.

Air will get up. Air will be pulled up, it doesn't even have to be air tight, just tight enough that it's easier to get air in up the hose than it would be from anywhere else.

SRI or CAI, it doesn't matter. Why? Simple. Once the air enters the intake it goes to the turbo where it gets compressed. When air gets compressed it gets hot. Much hotter than the ambient air temp. So, no matter what intake you have, the air will be the same exact temp once it is compressed by the turbo charger. The air is then cooled by the intercooler before entering the TB, and then the cylinders. If you want to lower intake temps get a larger intercooler on top, or even better a FMIC. That will make a difference.

The only thing you shoule be worried about when choosing an intake for your turbo car is the diameter of the pipe, and if the air flow is smooth or not. You want the air flow to be smooth so that your MAF sensor does not go crazy.

Also, Cobb stated that the diference between a CAI and SRI is nill because of the reasons I've stated above. They said from the get go that they would produce the box to satisfy the customers that want one, but make sure to tell the customers that there is no gain in performance to having it.

I would be doubtful of that same temp claim. Air heats up when you compress it, but your final temp will be dependant upon the intake temp. Compressing adds a consistent number of degrees in temp, added to the original temp you started with. Now, depending on excess intercooler capacity this could smooth it out between them somewhat. But no matter what a company tells you, a product most certainly can't defy the laws of thermodynamics and physics

No, it won't. Different intake temperatures will lead to different air densities which will lead to different rates of compression which will in turn lead to different temperatures exiting the turbo.

having owned both mscai and now owning cobb sri i can tell you there is mabe 1 degree of diffrence in air temp, based off diffrence in air temp. the sri heats up faster but as soon as you get any movement it comes right back to where the cai would be. by the way the cai will heat up at a stop as well. i also think where the cai draws in air at those vents in wheel well is a low pressure area. would be better if could wrap it around the radiator and get some of that fresh high pressure air. that little opening for the regular 3 wont flow enough air for our intake beacuse it is for the battary vent granted it will help out a bit. gains between the both is nill same 1/4 mile times. the thaing i like most about the sri is im not as concerned about standing water on the road im not trying as hard to pick the line that avoids the watter. as far as temps go i see it is off by mabe 3-4 deg ambiant to IAT both systems.

interesting point... the CAI walls soaking in the same environment for time = 0sec

 

[whitey4311]

Why do people think the CAI has no air down in the wheel well?

Look from the front of your car at the left corner lower grill and you can see the filter and its metal housing sitting slightly to the left and about 12inches back. It gets fresh air right from the front grill passing over it. It does not take air from the wheel well vents and it could not be any better then where it is getting the outside grill air passing over it.

having both which would you say gave more power? im debating whether or not to buy CAI to see the difference

I had the MS-CAI on my car for about 12,000 miles. I now have had the Cobb SRI on for a couple thousand miles. Honestly seat of the pants there isn't a real noticeable difference in the two. I never worried about hydrolock because I don't drive through water that is more than 6 inches deep. It will be a lot easier to clean or change filters though and to me that is a plus. I would like to see the cold air box come out and give it a try. I am sure there are going to be occasions where the cooler air will be noticeable compared to the SRI only.
Thats my $.02.

 

[dkswim]

seat of the pants tells me no real power diffrence. i like the sri a little better it was way easyier to install. change out and clean filter without having to take jack the car up. and not concerned about the water on the road as much...
whitney your right i looked at the car there is a vent that routs the air into that area from the grill now i know whare to extend some piping to get a ram air type system. but my point is that right were that vent in the wheel well is, is traditionaly a low pressure area on cars.

looks like afe cai's. waiting to see how all this plays out before i dump $$ on cobb or anyone else. seems cobb is the consensus though.

 

[jaydubz]

I just dont understand why they dont have some ducting that pulls from the front of the car also such as a ram air design? Along with the piping from the lower section that is sure to help deliver fresh air that is a few degrees cooler or in essence easier to breathe. I really wonder why no one has encorporate this design. I really wish I had skills with molding things and fabricating.

i thought the same thing

just installed my COBB intake tonight ... i was completely taken aback by the sound

 

[B-Dirty]

Ok, so the box is obviously out there in the developmental world, But when is it comming out? Anybody have anything more on this?

Ok guys one more time. From the front of the car through the plastic grill you can see the CAI filter element. Get on your knees and shine a light through the lower left corner of the grill just below the mustache and you will see what I mean. It is getting air directly from the front grill passing over it, not the wheel well slots or any other little lo pressure slots.

Just installed my COBB SRI today and I have to echo what everyone else has said.... It is Awesome!!!(rockon)

+1 When is this box slated to come to market?
