Jcoop Coop Don't gang tie heavy ampage draws together. Anything using more that 20 amp of steady load need relays. The main problem is not the steady load, it's the surge when you first turn on the curcuit. This is the reason for slow blow fuses. The spike from turning on a curcuit like a fuel pump or electric fan is 35-50 amps. The 30 amp relays can handle the power spikes alot better than any switch. Most switches are rated at 15 or 20 amps max. I auto cross and road race. I use my accusump as a preoiler for the motor and to keep
oil pressure up in long sweeping turns of almost 1 G. This keeps the pressure safe for the motor at 40 psi on the turn. After the race I rev the motor to fill the accusump backup to full and turn off. This way it is ready for the next race. I am going dry sump on the next motor. This is a cheap way to keep a motor alive on a race track without the 3K other system. IMO I would ask Canton if they have a higher pressure switch for the motor, 30 psi min. IMO 20 psi of
oil pressure is too low if you are racing. 40 would be better. Just MO. If any thing a would add a low
oil pressure light on the dash, for racing. Auto meter sells them. Rick L.
