It won't even do that if you fly wide open throttle - which if above 8K I assume everyone does. Steve Bennett had a chart that showed what information could be derived from a vaccuum gauge. I just went looking for it but couldn't find it. It's out there on the internet - behavior of the needle indicating various possible engine problems. Steve once recommended I put one in so I did . . . but I've never found the gauge useful at all. The way I fly, unless I've just taken off and am climbing, it always reads zero.
