With a 8 rib 3.0 and the 1:1 cog drive on the rear to elimiante any slippage, we made 14 psi. So we are changing to the OD rear cog and maybe back to the 3.2 to make around 16 psi.

Generally, at least on my car, any pulley change we make results in a 2lb change in the boost. The 3.4 made 10.5, the 3.2 made 12.5 and the 3.0 made just over 14.
