your friend has no idea how an engine works if he thinks that an underdrive pulley takes power from your battery and alternator and gives it to your engine.


but yeah, like he said, I have a full pulley set on my car and my alternator only charges like 13volts on idle, and the headlights would dim too, but that was fixed by grounding my alternator better.

but what you need to look out for is that your temp might go up because it also turns the water pump less, which might cause your car to overheat. But that just mainly happens on cars that have a small cooling system, but the 240 has a little bit more than it needs stock, so I really dont notice any problems and I'm running a single cam radiator in my car.
