Leon, another thing I like to do is use a relay to drop out all unnecessary items during cranking. On this car, being a street car, I left the parking lights avalible for safety, but the relays for fans, headlights, etc. all lose their grounds during cranking for more voltage. I also "DUH" proof the electric fuel pump by tying the tach, line lock, etc into the circuit, so if the pump isn't turned on, you notice it fast. I design my systems for the application - a show car will be more geared towards hiding everything, and a race car will be geared for function with more attention to voltage drops.
