I'll try it.

I was just curious because when I had the 1:1 pulley set i could push the gas and as the rpms went up the blower turned faster (obviously not into boost) and the vacuum went down like normal. Of course when it hit boost it would be PSI.
So if the vacuum decreases by spinning the blower a little faster with a 1:1 in back it would make sense that putting an overdrive set where it was, say, 1.5:1 then the vacuum would decrease.
Anyone who get's in their car with a boost gauge can lightly push on the gas and watch the vacuum go down.
So if it's N/A it happens with only the natural piston flow. But with the blower, IF it were actually trying to create a little boost it could plausibly lower the vacuum.
I did not stay at a Holiday Inn so I may sound like an idiot. If so just tell me.
