I thought you were saying that they are equal, which they arent, they're just different ways to measure pressure.

I totally agree, they aren't equal at all, a pressure just cannot be defined as a mass over a surface... saying 1kPa=1kg/cm2 is not true, but it's not far from being true... but anyway, who cares ?
as for BOV, it will just release the pressure without stoping the compressor wheel. Then, with a BOV, the turbo is still spinning when you step on the throttle, 1/2 second after... while re-circulating it will just keep the right air-fuel ratio...
what kills the turbo is the compressor blades stalling due to the reverse air flow and thus creating vibrations. What is going to fail in a turbo is the bearings, and I don't think they can fail because it suddently stops, they will fail because of excess stress, caused by vibrations ( turbo out of efficiency range or having violent surges ) Can the turbo handle it ? I'm pretty sure it will, just depends how long you consider a turbo is supposed to last...
and the excess fuel caused by the atmosphere venting won't do much at high rpms cause it'll be already out of your exhaust at the moment you step on gas, then your A/F ratio will be just right when you ask for power again. not sure if it will be the same at 4-5000 RPM tho, I didn't run atmosphere long enough to notice the difference...
