was wondering if anyone knew if the air raid cool system would work with the supercharger setup. Some have said that you cant use the air raid or the kn sytems if you have installed the supercharger.
will air raid system work with supercharger

I'm not understanding why ppl are saying that if you install a cai that it will cause the truck to lean out... Correct me if i'm wrong and I probably am but when you add a cai on a n/a car/truck it uses more gas because it causes the car/truck to run richer... Is it different on a force induction vehicle??

I don't think you have your terminology correct. When an engine runs lean or rich it does not only depend on the amount of fuel the ECU is injecting into the engine. It is the mixture of air to fuel that causes a lean or rich condition. If that mixture is not balanced to a stoichiometric value of 14.7:1 air to fuel, then it is said to be either rich if less than 14.7 or lean if greater than 14.7. So when you say that by adding a CAI(which by the way an AIRAID is far from a CAI) the engine burns more gas causing it to run richer, this implies all you are doing is adding more fuel. In reality what you are doing with a device like the AIRAID tube is eliminating some air restrictions which will initially cause you to run lean, but through time the ECU should learn the new settings for the sensor readings to bring it back to the stoichiometric ratio. The advantage comes from the ability to flow more air through the tube(into the engine) which will demand more fuel which will give you more power. When at WOT your ECU will no longer be in closed loop mode and will be controlling the fuel delivery system based off a default table which can cause you to run lean since that default table is set for a completely stock engine. This is why a SCed engine without fuel mods runs lean. If you perform any of the intake mods to that condition you can make matters even worst and cause it to run even more lean.busakiller said:
Now to the best of my knowledge there is no real CAI bolt on set up for our trucks. I may be wrong, but the last time I searched there was nothing out there.

Thanks for the good info dcabtaco... I have the s/c and 7th injector installed right now... From what I heard it make the truck run a little rich... I haven't heard any pinging so far but I'm not impressed with the performance.. I was wondering how much of a difference was it when you installed your 2.2" pulley... Would my setup be able to handle that pulley size w/o leaning the truck out...

Well from what I hear the 7th does make the engine run rich. If you are concerned about that the first thing I would suggest is getting the AIC from URD so you can tune it up the right way. From there I would consider an upgrade on the fuel pump. If you still want to increase the power then I would look into the 2.2" pulley, but only if you also include the water injection. With higher boost you will get higher EGTs so you have to control them with the WI. If you have not done so already read gadgets site and then you will understand why he has such good products for our truck. He went through the research of all this so no need to reinvent the wheel.
