That 36.3psi appears to include the 14.7psi of ambient air at sea level.

So really, more like the 21.6psi peak, which is spot on what some other sources are quoting (most saying 22psi)

Edit: Regardless, you can't really compare pressure between different turbos because you need to factor in the compressor map and flow.

Think of it this way, blowing high pressure through a drinking straw doesn't really move much air out of the end of it.... a light breeze flowing through drain pipe is moving significantly more air with much less pressure. Flow is king, not pressure alone.
Damn, that's one hell of a blow job!
