Does any body know how many amps are used “normally “ by a 2005 Mustang Gt? My alternator is rated at 135 amps. I’m not sure if that is enough with my added mods. I’ve added Edelbrock supercharger, intercooler water pump and heat exchanger fans , boost a pump for fuel pump , Interceptor gauge and water temp gauge. Aftermarket radio with backup camera. Running Lito tune.

The car died at idle Sunday at RR tracks. Battery gauge on dash was all the way to the left and Interceptor stopped working. Would not turn over until jumped. When I got home battery was at 12.2V and alternator was 13.9V on multimeter.

Been ok since.
