too much boost?
recently my boost gauge is showing increased boost levels.
I have a second gen supercharger and it was always very consistent at 6 pounds of boost.
recently i have been reaching as much as 8 pounds according to the boost gauge. This is usually at wide open throttle.
should i be concerned?

It is normal for that to happen in colder weather. I hit 10 PSI sometimes with my opened induction system.

Well, not really. The O2 content is still about 21% no matter what the temp is. It is more dense at colder temps. What that means is that the engine can intake more dense air on each cycle and can make more power from it.
It is like you are on a mountain. The air is less dense, and only so much power can be made. Now go down to sea level and it is more dense because the pressure is greater and the engine can take in more on each cycle and make more power. The same thing happens with temp. I think it is called Henry's Law about how a gasses density changes as its temp changes.
You are right, but not completely.

Ummm... yes, dense = more compact = more O2 in a given volume when the air is colder, thus it can be thought of as taking a bigger "bite" with the same size mouth when the air is colder.
