WHAT TYPE OF BRAKE PRESSURE DO I NEED TO RUN FRONT AND REAR ON MY MANUAL BRAKE SET-UP?

You should be able to achieve 950-1200 psi on the rear brakes and 700-800 psi on the front brakes. Usually, more brake pressure is used for the rear brakes, since in most drag racing applications, the rear tire has a much larger contact surface (with the pavement), when compared with the front tire; however, builder and driver preference may influence the choice of brake bias.
