How would the 1g make more horse power if both cars are running the same PSI. In theory the 2g should be making more HP because of the compression ratio.
This could go into turbo efficiency
if a 1g and a 2g were equal (exept for the compression) with the same turbo, 14b the 2g should be kicking the 1g butt. This could explain why the 14b is a popular upgrade for a 2g.

Like I said the 2g makes less power for several reasons, mainly the BOV and smaller turbo. If everything else was equal the 2g head should be making more power, lower in the RPM range. When you start getting to higher HP levels you will have to start putting some money into the 2g head sooner.
Also, "the 2g should be kicking 1g butt", I don't think you will be seeing anything that drastic. You spend most of the time in the upper RPM range while racing so the difference would be minimal.
