I was thinking of using my Mallory ignition (685) box to turn on my second fuel pump. Its has a built in window switch that can be set at any rpm.
I can set it to turn on at 2500rpm and turn it off past my rev limiter. Does anyone see a problem with this

The only reason I want to do this my pressure switch does not turn my 2nd pump on till 6-8lbs of boost. I want it to turn on earlier. Buddy sold me the wrong pressure switch. I could also use the switch to turn on my meth/water kit

RPM is not load dependent so I always use boost.

3000rpm at part throttle has a much different requirement than full throttle.
