View Full Version : Smaller alternator?

04-19-2019, 05:51 PM
There's nothing wrong with my current (stock) alternator, but I've been wondering for a while now: Should it ever die, could I get away with using a smaller/lighter one? The pusher fan is no longer present on my car, but I do have an intercooler fan that's always running.

If not, so be it, but everything's an opportunity for weight savings.

You could read the voltage and current output specs for the stock unit and then find something that fits the SC soE wise. Then see if the flow is similar. Ideally you’d need to know the total Amp draw of your car with everything running/in use.
