Miguels Posted June 21, 2012 Report Share Posted June 21, 2012 not really. i doubt the hfi amps do rated. and depends on how many amps does your alternator put out Quote my logshttp://www.stevemead...-my-new-set-up/my blow through loghttp://www.stevemead...future-updates/ 96 ss http://www.stevemeadedesigns.com/board/topic/164094-96-impala-ss-build/ Link to comment Share on other sites More sharing options...
Colin - STAPUFT Posted June 21, 2012 Report Share Posted June 21, 2012 You can do the big 3 and it will help you some, but you will have massive voltage drops. It is going to be hard on your equipment, hard on your vehicle and the OEM alt.
