How else is the 2.0l 6 pot RB20DET Nissan engine capable of producing over 500hp?

You're talking about mapped fuelling based on boost pressure. Read up on mass air flow metering, or Karmen Vortex metering (thanks Gary). >> >> > >I would think that it, *assuming* 100% coupling, it would take more >torque to spin two wheels vs. spin one wheel.
