Which "drag race" master cylinder?

" Getting wrapped up in it " wasnt directed at you, sorry you took it that way.
What I was trying to say, was as a whole, many people get all wrapped up in the bore thing.

I have used different disc MC's, and in my experience, they all feel the same.

a 1/16" inch increase in master cylinder bore size requires a 12% increase in leg for the same pressure
a small 15/16" master and a 'cuda 2 3/4" caliper piston will stop effortlessly,almost like power brakes.
..if you go from 15/16 master to 1 1/16 you will require 24% more leg
