[urq] Turbocharging & Elevations

I don't think so. An engine might be making 400 hp, but after driveline
losses, that equates to something under that -- typically losses amount to
20% give or take another 5%.  So while the engine may put out 400 hp, that
may be 300 hp at the wheels.

HP doesn't tell the whole story, of course.  HP is really nice, but torque
is what really does it for me :-)
