Doc,
Thanks for the information. I am aware of the dangers associated with CO and have spent too little time dealing with them.
I do use the cannulas and in the past thought them to be of some help but clearly they cannot offset the CO in the cockpit. Putting the exhaust extensions on kept the largest part of the bad stuff out of the cockpit during all stages of the flight. That combined with the O2 helped me to make the 9 hour flight to Kalispell from OSH and arrive much more clear headed and fresh (butt was still sore, and am working on that too).
The guys in Deer Valley that have gone to the side exhaust report clear cockpits even during smoke use and maneuvers. I would think that a side exhaust could work for the 50 quite well. TJ should be able to evaluate that as he is on site there.
In your system are you breathing pure O2 in the mask? If not, where do you get your regular air from to mix with the O2?
BTW, living in Oregon with lots of high ground around I wear the O2 for altitude as well. Trash air and altitude don't mix well! This last trip was a pleasure compared to the earlier ones.

Batman,
I am using a Scuba Pro Stage One and Stage 2 regulator with a 3200 psi pony tank. The mouth piece is removed from the stage II and an military fabric wound O2 hose is zip tied to it for a secure fit. Then I use the standard Military Aviator’s O2 mask. With this system, I can use up to a 70:30 Nitrox mixture for altitude up to 12 K. I am looking into getting a 5000 PSI kevalar wrapped tank that holds 80 Cubic Feet of air.
My current field elevation is 190 ft. So I’m not plagued by the tall rocks like you guys up in Oregon. The above system ensures that I am breathing fresh air during the high CO times of the sortie. Otherwise, I drop the mask or loosen it up to breathe around it during flight at altitude.
