I have a severe problem with my KORE CAI. The CAI itself is great, but I made a mistake by cutting fender well hole way too big. This made my CAI to move freely. After complaining about bad acceleration and throttle response for about a year, I realized that it is a problem of my CAI that caused all this (I also didn't notice any improvement after installing BIM and BTB). To verify this, I put the stock intake system, and drove car for few minutes... and I was shocked to feel that my car now accelerated really smooth.

I guess the bad acceleration was due to CAI that moves freely. I think this caused irregular airflow, thus bad acceleration and no power (this is more noticeable when accelerating between 10 - 50 MPH).

If you see the picture below (AEM intake), there is, circled in red, adapter kind of thing that make the CAI attach to car's body. My KORE CAI, unfortunately, does not have that thing. I am wondering if I can do anything to my CAI so that it sticks to one place and not move freely.

 

whip out your welding tools and make something to hold the CAI.

Use rubber hosing to "ring" the engine shield to make a tight fit between the CAI and the engine shield.

 

i cant imagine how it shaking around would restrict air flow?????
its going to suck in air at the same rate (i would figure) if it was moving around or not....

 

I think I will go with rubber wrapping thing... That ought be really thick wrap though...

I am not good at Physics, but I think air will have harder time moving around when the tubing is not in one position. I think it creates airflow disruption.

 

just a simple idea... take a drill, drill a small hole somewhere aroudn teh cai and take some wire(like thick ass wire almost like those flags they put down when they are spraying) and wrap that aroudn teh CAi put it through the hole and twist it tight as hell and that should hold that baby in place

 

Here's how we mounted our Ghetto Random Special:



Just used some metal strapping and a couple of bolts ... there happened to be a handy hole in the metal underneath there to bolt it to ...

an example=
if you take a vacuum and hold it up when it is sucking in air its going to pull in about the same amount of air if its standing still as if you are moving it side to side. This is what your engine is doing. The air that is being 'disrupted' is displaced by more air, so therefor there shouldnt be any noticable difference and i would think the problem you have is from something else.

 

The movement of the CAI may be transmitting vibration to the MAF which MIGHT be altering air flow readings. MIGHT.

Hey, if he tested it, and it works better for him, more power to him. I can't think of why it would matter either, but hey, if it works...do it.

If you take an old radiator hose of say 1" diameter, then cut it open into a "U shape" down the length of the hose, you can use that to "ring" the hole in the plastic engine shield. Use normal Silocone inside the hose to get the hose to stick to the plastic shield. You might have to experiment with several different hose sizes to close up the hole to the proper size. Don't silocone the hose till you know it's the right size.

On a closing note. Do NOT hard mount the CAI to the frame. The engine moves, the frame does not. I tried this ONCE. When drag racing (at a legal drag strip), the power of the launch, and the rapid engine movement, caused the intake to break off at one of the hose connections. Unfortunately, the MAF and filter werer on one side, and the engine on the other. The ECU no longer got MAF readings....so I could not move the car above an idle speed... It did give me a spectacular 27.7 1/8th mile time. I don't know what my 1/4 mile time was, as their timer shuts off after 30 seconds....

 

LOL!

 

Thanks for good info/comments. I bought heat shield paper with forms from hardware store. I am going to wrap them around my CAI to match the openining hole. That should pretty much hold CAI in one place with just little bit of movements. I'll report after I retest.
