[QUOTE="gnxtc2, post: 1523876, member: 1414"] Let's see what I remember from my motors class.....DC motors are rated in kW instead of HP which really means nothing here unless you know the rest of the specs (nameplate). The armature and field winding are bigger on the 6.7 starter, just going off of the video. If the wiring of field winding is larger in size, it'll have less resistance. Therefore, by reducing field current, the speed also increase which leads to increase in mechanical power output. I built my own battery cables out of welding cable. This is the wire size I used: Positive - battery to starter -> 4/0 - battery to battery -> 3/0 - battery to solenoid -> #1 (I think) Negative - both batteries -> 3/0 I switched over to military style battery terminals. When the glow plugs activated, my battery voltage was 10.9v with the old cables. After I built my cables, the battery voltage is 11.4-11.5 with the glow plugs activated. The battery voltage is read through the factory AIC while I wait for the GPs to heat up. I know for a fact that the 6.7 starter cranks way faster than the SD 7.3 starter vs the 7.3 OBS starter.
