O2 sensor location?

[scrapmaster]

just wondering where on the pipe the sensor for an af gauge should be mounted.. also what is a safe af ratio on a non turbo sled? thanks in advance

I am about to mount one in my X-fire 1000. I bought the NGK AFX brand af guage. I was told by one of our site dealer sponsers to mount the O2 sensor as far from the engine as possible. That would be past the can where the pipe dumps down. This will keep the temps down as much as possible and help prolong the life of your sensor.
I will weld the bung in next week... and if we ever get some snow I will let you know how it works.
I was also told that a two stroke should run about 12.2-12.5, and a 4 stroker about 14-14.5.
I am assuming that those are non turbo #'s. (not sure if turbos are different) Maybe someone else who has run one can be of more help.

mount it in the can-12.75 is the ragged edge

any ideas what the best power source to use would be? ground to engine? done lots of vehicle wiring but never on sleds paranoid of tappin into the wrong power souce i hear that can turn out bad
