All in all, it's not a big gain by any stretch of the imagination. I would mainly consider it a longevity mod.


That was my whole point that he has repeated missed.

You effectively slow the alternator down which adds to longevity. Especially considering the engine's main powerband is 5000-7000rpm.

The exact same thing goes for a DMD. It reduces destructive harmonics, torsional bending, and crank whip which all get worse with rpm. Also which are an area this engine is known to have a problem in. (I.E. so many damaged rod bearings with perfect mains)
Then take into account the 5000-7000rpm main powerband and the time one would spend in it to drive this car like it meant to be driven and again it's a good idea for longevity.
It was only a "theory" you might gain power due to less bending & whip. Then a couple dynos said it may be true and this article did as well. This was never a mod that was done for the power increase.
