More pressure will not make more horsepower. What it will do is to overpower the needle and seat in the bowl of the carb and blow raw fuel into the intake manifold, creating a tuning nightmare. Shoot for 5 psi. You want high volume to prevent fuel starvation, with large diameter lines, not high pressure.
