Default Re: Slow starter

According to Dyke's Encyclopedia, the starter motor draws 175 Amps at 6V while cranking the engine with a (+) ground. The starter motor produces 3 lbs-ft of torque at 1500 RPM.

Running free, the starter motor draws 50Amps at 4000 RPM

A high compression cylinder head will increase the load on the started, so it draws more current from the battery. A modern battery should have about 500 Cold Cranking Amps capacity at 6V.
