I think Ted have a larger solid alloy crank pulley, smaller than 75 mm is not possible on the S/C because of the water pump bearring house.
The gain with the crank pulley will be 20-30 HP easily, perhaps thats why Ted's show so much more power.

Lucas, are you saying the 3.2V6 ?
the smallest pulley can clear the water pump bearing is 66 mm.
stock 75mm as you said.
Few ppl here put it & benefit the significant hp gains.

ahh..I always thought the boost was increased by software, but it's actually hardware.
