Message: <blockquote data-quote="dan filipi" data-source="post: 48887" data-attributes="member: 54">I don't think it would be worth the trouble to remove the stator since for one the starter clutch is part of the turning assembly and I think removing the flywheel effect the armature has might even unbalance the engine since it was designed into it originally.Would be worth trying if nothing else to see what happens.As for the drag effect an external has I haven't found it to be more than the internal, actually the reverse since the external is loading the engine for what it's being asked to put out only. The internal is loading the engine 100% all the time.Of course if a bunch more loads are asked of the alternator like extra driving lights it will load the engine more.That's to be expected. While your car is running, turn on the headlights you'll hear the engine slow down a bit usually.Noise I agree. The belt like on a car does make some noise. That is one reason I went with a flat belt since V belts are typically noisier as they slide and squeeze into the groove, flats lay on the pulley.The alternator itself makes a small amount of noise, mostly as a whine but both of these noises are minimal, the gains far outweigh this.</blockquote>
