I must be missing something! If you fit a 'performance crank pulley' i.e. under driven, apart from the harmonic balancing effect just like the standard pulley its only other job on a V10 is to drive the alternator. At a guess at 8000rpm that's worth about 0.25 bhp (or maybe less). The other possible benefit is that the engine will speed up and slow down a little quicker but no bhp increase. My question would be 'would you notice'?.

That’s because there probably isn’t any due to what Tom just pointed out in the post above you.
