Why 16 volt at all, i see no reason for it, even with a blower motor. It's kinda like he has it so maybe i need it. If you are trying to catch up with the top fuelers and funny cars, they start with 36 volts and run mags. If you want more voltage too the starter have it rewired to lessor voltage. Nothing makes sense to me too endanger all the gages,delays,trans brakes,etc. just to say i got a 16 volt system. Sounds to me like another expensive upgrade not needed.
