Cobb SF Intake released

i am tossing my CAI and building my SRI with Air Straightener and correct diameter size tubing.

i wish i could toss the entire intake and just stick a filter on the turbo inlet, but not sure how the maf would like that...lol...

EDIT: Going with SRI because, the fmic and cai is just toooo much piping. My engine bay looks like a sewer. I'm hoping throttle response improves a little bit, and i don't mind the 5-10 whp difference (if there even is one) by going with a sri
 
Cas, you could build a box surrounding the SRI and use rubber moulding up on the top of it to seal the hood. At the bottom of the box, you can add a few large holes and attach hose to pipe in cold air from the front. This will probably solve your problem without sacrificing any power. Shouldnt be to hard for you to accomplish! lol

i actually already have a plan. box it and block everything off besides a 3" x 3" opening between the light, and chasis metal bracing. it will pull cold air directly from the fog light ducting, the fog light opening itself (because its pulled) and several deflectors that actually aim right around that corner.

very easy to make. Cardboard box mold. Cut sheet metal. Weld together. Add a mounting bracket somewhere, done.

I'm not quite sure why Cobb hasn't thought about where mine will be placed. It can pull much more air then a 3/4" slit and thin tubing in the front grill. You are talking about a complete, pretty big cu. ft. space to pull cold air from and its easily accessible. Not to mention, air moves pretty freely through that area and is recycled right our the front of the wheel well. maybe i'm just a genius. lol

EDIT: Here is a pic of the opening i am talking about. The picture actually cuts it off. It is bigger then that. That brightness behind the cables is the ground/wheel well !!!! The opening is HUGE !!!!!

isnt that blocked by the front bumper and the inside panels of the wheel well? looks like a good spot tho i can see the light coming in
 
After work today, I data logged some under the hood temperatures.

I fastend an air probe (probe range = -50 to +250C) we use at work to the air box facing the MAF sensor. The probe was >2in from any surface area. I then programmed the reciever to sample at 1 minute intervals in Fahrenheit. The car was at ambient temperature as it had been sitting in a parking garage for over 8 hours. I let the probe temp stabilize and initiated my data log.

I drove a total of 10 miles in 18 minutes. The first part of the drive was between 30-45mph with multiple stops at lights. The last half of the drive was on the freeway averaging about 65mph. The last minute was just at idle in a parking lot.

nope, that is not blocked. its open right there. go check your own out.

Dave @ cobb stated they are no longer going with the slit design. They will be taking ambient air from somewhere else. probably the wheel well. atleast that is some good news.
 
just got my Cobb SF intake! :P

gives me something to do this Labor Day weekend. along with oil/filter change, Redline syn tranny fluid, and new Carbotech "Bobcat" pads on all 4 corners. (flash)

planning to dyno again on Sept. 15th on a Mustang dyno for direct comparison to Cobb's claimed performance gains. unfortunately, I won't have my own baseline on the Mustang. (flash)
 
I installed mine today. Took about 40 minutes. Just about the easiest install you can imagine.

Sound is of course pretty neat, probably not dissimilar from a CAI.

Power wise, its noticeable for sure, but i doubt its as effective as a CAI, I can break traction in 2nd really easily now.

Bottom line, if you are just looking for a super simple bolt on, that you can do yourself and not spend $350 or more (if installed at dealer) then the cobb intake is great and will give a very noticeable gain.

If you are trying to squeeze every ounce of power out of the car, go CAI.
 
I've got the MS CAI, and if I had the option at the time I would still choose the MS CAI. Sure it costs more, but you do get proportionally more power. It does take more install work, but I would still wager that nearly anyone can do it. If I had gotten a SRI I know I would be kickin myself later on when I would know that I could have gotten more. In the long run, an extra $50-125 and 1-2 hours is well worth it, and you can rest easy knowing that you haven't compromised.
 
So after having the intake for a few more days, I have to say that my initial impressions were a little off.

Power wise I'd bet its making just slightly less than the cai in real driving situations. The dyno numbers are a little lower because you can't really duplicate moving through the air at speed with a fan, or even a few fans.

Honestly, I'm very pleased with my purchase. The only drawback I can find with this system is that it uses an oiled filter. After talking to a few ms CAI owners I think I might prefer a dryflow filter. But the gains you'll get from lowering air temps slightly (which I think is nullified by the hot turbo and intercooler) are probably similar to the gains you get by eliminating restrictive piping.

I Honestly beleive that these two systems, though different gains are shown on dynos, have nearly identical gains in REAL DRIVING SITUATIONS. Obviously I can't really back this up with dyno sheets or anything and will probably get flamed and the SRI vs CAI debate will continue, but all in all, I'm happy with the purchase. An MS3 with cai vs. an ms3 with sri will ALWAYS be a drivers race.

Bottom line, the system looks and sounds great, and you probably won't notice a difference between different intakes in terms of the gains, so buy the one that fits your personal preference. If you want the one that shows the biggest gains on a dyno, go for that, if you want to factor in other things like cost, aesthetics, ease of install / maintenance, etc... go for that, but for the love of god, get rid of your stock airbox!!!
 
I'm still stock. Still looking at the options. My car is still fast though considering the other cars on the autobahn. What about the BEGi SRI? Anyone try that shoe, and did it fit?

Anybody kill a 06-07 Mustang GT yet? How did it feel?

My buddy has but he has a MS3 with intake, downpipe and test pipe against a 07 Mustang GT, manual with intake, tune and 410 gears. The MS3 wins from a 60mph roll about a 1/2 car length.
 
From what I've seen of the begi it still uses the stock "accordion" piping, its just a new filter and an enclosure + MAF housing. begi is a fairly reputable company, but just looking at the system I'm not convinced. Maybe thats what people said about the cobb system though, so I'm not going to bash it.

Its the same price as the cobb, and you get a housing for the filter that you can have powdercoated or polished, which aesthetically is pretty clean, but see earlier in this thread for a discussion of filter boxes.

I don't know anyone who has tried it yet, but as I said, begi knows what they are doing, so does cobb, so does injen (and fujita), and so does mazdaspeed.

I've been looking for a Mustang GT owner so bad...

I keep getting outclassed races.

My first race was an SRT-4, which was awesome. Yay me.

Second, a Z04 Vette. Aw. I needs more power modifications... I had to beat him by driving like a dick on the interstate. Yay me.

Third, an OLD Mustang from the 80's with all KINDS of work done, it growled like a frickin' behemoth - hick type guy driving, but cool race. Aw, me, I got Pwnd.

Fourth, this morning, 630am. One of those hard ass Cadillac two doors roadsters which, apparently... Are frelling bad ass. He TOTALLY kicked my ass, I was just playing keep up. I may have done better had I not spun my tires in both first and second - I'm a dumbass, but turning the traction stuff before I start her is yet fun as hell!
 
NO CELs, its not obnoxiously loud, you can hear the BOV real nice now, and it makes that delightful "sucking" noise once the turbo spools.

On a scale of 1-10 for loudness increase, 1 being no change, and 10 being "I just removed my muffler!" I'd rate it at a 3, its slightly louder, but now you can really hear the turbo sounds.

Also, remember loud != fast.
 
I haven't decided on which but the cobb with the box may be nice and quiet. I was thinking the cobb with the box and dynamat or rammat the inside and make it nice and quiet. what u think?
 
it is quiet unless you are in boost.

It might be hard to keep the bov and turbo silent if you are using any kind of open element filter, maybe the begi system would be quieter?

Putting sound deadening material in your engine bay sounds like a bad idea to me.
