I noticed that everyone has been talking about the new straight shot CAI. Everyone thinks its won't produce any power mainly because the tube heats up and the incoming cold air just isn't cold any more. So I was thinking well what if you wrapped the tube with insulation. I don't know what it's called or were to get it but it's the kind you wrap around intakes to protect them from the heat of a turbo and it's a cloth not the shinny bag looking insulator. This does take the look away but it's going to add function. Now I think it's still going to get warm but not as hot as before and will take a much longer time to heat up. Do you think it will work?
straight shot idea!

Ive seen this done and it does take away from the looks of it but it probably will work. The way i think is that even though the tube gets warm when you get on the gas the air that is getting drawn in isnt going to stay in the intake tube long enough to get as hot as the tube itself anyway. just my thoughts about it.
I got a little bit of pinging after i installed it for just a second when you stab the throttle and then it goes away. Did you have anything like this with yours? Ill call Mac monday and talk with their tech dept. about it and possibly a dyno slip to stop the arguing about these kits being bs.

You won't notice the difference. Just leave it alone so you can enjoy the looks of it and if you are at the track and want to help it out then throw a bag of ice over it while you're waiting in line.

It won't make a noticable (or measureable) difference and it'll look like crap...IMO, don't bother. The air rushing thru doesn't have time to be affected by the temp of the tube.
I guess the air really couldn't heat up that much and even if it did it's not enough to take power away. If anything it will help a little with the mixing of the fuel and air. I guess it really doesn’t do anything but give you a little better sound. Cold air intakes don’t increase mean effective pressure or volumetric efficiency but will let the engine rev easier. Less resistance or vacuum at high rpms is always better but your TB is what restricts you engine and more CFM's = More RPMs. So the easy breathing only helps with Higher Rpms or more cubes and high flowing ports.
281 * 6000 rpms = 1686000 \ 3456 = 487cfm at 100% VE

yea people always said that all the metel cai get too hot, but the air is only in there for 1 second, it dont matter. i want the strait shot but does it make the car run too lean?????? especially if you have a plenum/ tb already?
i need to find this out, i dont want my car running lean.

How can it lean you out if the MAF is calibrated for your computer and injectors?!
Everybody keeps saying this but it doesn't make since to me.
Yes it's more air but that's why it's calibrated, isn't it?

It all relates to the transfer functions in the computer. Your maf outputs volts depending on airflow across the elements which are positioned in a metered orifice. The computer knows that an exact amount of air can travel through that orifice at a given temperature. What most of the aftermarket maf's do is decrease the airflow across the elements in effect fooling the computer into thinking it is getting less air than it actually is so it leans out the A/F ratio. The problem is that when you install one of these the engine load changes and so does the spark which usually advances. Combine that with an unknown amount of A/F ratio change and it can spell disaster to your motor.
All of the power gains with these mafs are solely related to advancing the timing and leaning out the mix but the problem is that you have know idea how much or which way it is changing, not to mention the fact that putting any bends infront of the maf creates turbulence and screws it up further.
Until the output voltage reaches the max which I think is 4.75 volts there is nothing to be gained from a larger maf.
