Like any other mod, increasing the CuI. of the engine will net you some more power, but how much more depends on your setup. If you do nothing to the intake/exhaust then you will see marginal gains, if you do head work and intake porting you will see more, couple that with good headers and good TB/MAF and you'll see even more... When it comes down to it, the combustion engine is nothing more than a sophisticate air pump... more air in = more power out.
