GT 500 Boost

Just curious, how much boost does the GT 500 put out from the factory?

I don't know why....but for some reason 8.5 keeps coming to my mind....but for the life of me, I don't know where I got that from.

All that power sounds so good too.....not obnoxious and overwhelming...but smooth and refined .
