Custom 2005 LS CAI...

Ok, well I have been talking about doing this for a little while now. I finally got off my lazy butt and had at it. This is the first version I will offer.

I plan to offer a fenderwell CAI but will continue the fab work on that when it gets warmer out. That should only be about 1 more month till I can work on it outside in the sunshine.

With this CAI and a tune from SCT the cars really has woken up, especially by eliminating that crappy torque control and other stuff that makes the TBW so sluggish. Sure will be nice to take it to the dyno to see what numbers it puts down. Nothing big of course, but just curious to see what the exact gains are.

Here are the pics.

Very nice! You mention the tune ... do you know if the SCT flash leaves a "fingerprint" in the PCM? In other words, can the service people tell that you have changed the tune if you change it back to stock before taking the car for service?

As long as you retune it back to stock and then let the adaptive learning relearn things for a little while you should be ok.

That is also why I am keeping my stock intake so that when I bring the car in for service it will be totally stock. Another great thing is that being that it is not a mustang the service people will be waaay more lax on seeing if it had any mods that caused the failure to whatever part that needs to be fixed. Bottom line is that you will be fine. That is why I am doing it. Heck I am still under warranty for quite a while like yourself too.

From what I was told, when you connect the SCT for the very first time, it immediately downloads your stock PCM image. You wind up with the stock flash, plus two "tuned" flashes, so if you need to go back to stock, you simply reload the stock program.
 
so how do I order one and how much $$$? seriously....
 
That's an interesting set up. When working with KKM on their version of the 03 and up V8 system they showed no real gain by replacing the stock intake tube. That's why they offer just the MAF replacement part with the filter. Some gain came from removing the air baffle attached to the tube.

I'd be interested to see what the dyno numbers say without the SCT flash.
 
One more observation. The stock MAF on the 03 and up LS is calibrated for the diameter and steps in the stock housing bore, if you change that, you change the output voltage. If the voltage signal is higher (ECU thinks more airflow) the mixture will be richer, and a lower voltage signal (less airflow), it will be leaner. Get too far out of the anticipated ECU range....... check engine light.

Have you experienced any CEL's since installing it?
 
Would I have any problems with just removing the resonators on mine so I get more of the intake growl when you mash on the throttle?
 
you can remove the resonators or cut the bottom of the box out. but be careful you get a LOT of extra growl namely at low RPM's...

It may not gain a whole heck of a lot in terms of power, but then again intakes aren't really high power mods, so any addition when compared to the power already gained will be a welcome one. I also didn't like the look of keeping the stock intake tube, especially with all the extra crapola attached to it. Just looked too ugly to me IMO.

Its cool, I know that. When given the calculation of air movement, you need to know what voltage (or MAF counts) you will read at a given airflow. Airflow is calculate by a volume over time. To find that volume you need to know the area of the hole in the MAS housing through which the air is moving. It is cool, I do my own tuning with SCT Advantage software on my other vehicle and know a pretty decent amount about properly tuning vehicles, and what not to do. So in answer to your question, no CEL's. :D

As long as they are sealed back up. This is something you probably already know but if they are left open a huge vacuum leak will occur that will destroy your MAS's metering capabilities.

That's cool. I was just under the impression you were going to start selling these and just wanted to make sure you have eliminated the CEL problem. Also, if you do decide to sell these the customer will have to have the same SCT flasher unit and tune you have since it is specific to that particular air intake system. Interesting set up though.

No no no. The intake doesnt require a tune. It is self sufficient without one. I just mentioned tuning with SCT as a reference when talking about MAS voltage being thrown off by different size MAS housings. The MAS housing is the same internal dimemsions as the stock housing (area where the slot-in sensor bolts). Unless these cars (03-06) see some serious mods available for them around the corner then there really isn't a need for things such as bigger MAS housings. As you know, there is a thing called overkill; and that especially applies to a vehicle in mildly modded form like the 03+ LS's.

BTW Ken you got a PM.

Yes, quite a few now actually. Exterior and engine bay with the custom Kenne Bell 2.2 supercharger in there. Just email me if you want to have a look-see.
