My Build Thread
"CMAX"

--------------------------------------------------------------------------------

This will be the start of my build thread. My newly purchased 2011 2500HD LTZ will be undergoing a plethorea of modifications to make it more "capable" as it were. I already own a super capable off road sort of semi militarized truck so this one will not focus on the off road thing as the primary design factor.
I think the truck should retain all it's off road prowess and perhaps even be enhanced in some areas such ar undercarriage armor and suspension travel, but I am not going to SAS this truck like I did with my other truck.

Edit: When I wrote this I thought Obama was finished in 1 term...He got re-elected...I have hence forth lost my mind and after some 7oo odd pages from here, you will see I was not telling the truth about the SAS thing, nor have I kept this project as sane as I envisioned when I thought our nation was soon to be saved...

I want it to have good bumpers just in case I need to push stuff out of the way, a self recovery capability if I need that, more engine power but only if it does not adversly affect mileage, much longer range while enhancing the multi fuel capabilities. It would be able to safely carry my family over great distances while negotiating anything from a tractor trail around a field to a debris strewn roadway. Well, more on my thinking and the vehicle mission statement later on as this thread developes. I think some of you will understand where I am going with this especially in view of the particuliar design charactersitics of my Tundra.

OVERWATCH_09:
Here's the first modification that any country gentleman will well understand.
The position of the Glock is only inches from my hand while holding the steering wheel. I need to practice at a range (farm) drawing and engaging so I don't ventilate my passenger door frame!
      



OVERWATCH_09:
Next I decided to do something to improve the mileage which was historically running in at 16.4 overall.
I started with adding an air intake system. After talking to Holton over at Alligator performance, he recommended an S&B intake for my application
Here is the factory intake system after removal .


Here is the vacant spot sans factory air box

Next the factory steel air box mount is removed


The factory MAF and filter life units are removed and installed on the new air box

OVERWATCH_09:
Here is the intake tube end showing the air bellows which is a smooth venturi molded into the tube itself       

The build up of the S&B continues. The filter element is much like the K&N which I have used on everything from past trucks to even Huey and Chinook helicopters




OVERWATCH_09:
The air box has an option to either leave the bottom of the box open for additional air flow or to colse it off. Since the orientation of the opening is straight down, and considering the possibility for emergency deep water fording, I elected to close it off
