Here's a simpler way to do what you want. Use an adjustable vacuum switch that closes when vacuum drops. Plumb it to full manifold vacuum and wire through an oil pressure safety switch. This way the water injection would only run when the engine was under a heavy load. The oil pressure safety switch would ensure that it would only pump water when the engine was running.
