Just so no one is confused a larger bore MC will provide less pressure in the system than one with a smaller bore. But the the larger bore will require less pedal travel to move the same amount of fluid.
For example: Lets say you have a MC with a 1 insq bore and you apply 100 lbs of force onto the MC. You will generate 100 lbs / 1 insq or 100 psi. If you have a MC with a 1/2 insq bore then it would be 100 lbs / .5 insq or 200 psi.
