light weight after market pulleys
do light weight aftermarket pullys like buddy club and toda racing kill your battery ? is it only if you delete the a/c pulley , but keep the a/c ? ballade sports has this quote on there web site about the buddy club pulley , whats the deel on this ?
Note: This pulley kit is designed and intended for motorsport applications. Running the air conditioner and headlights at idle can cause an insufficient battery charge.

That is what Toda and other JDM aftermarket light weight pulley makers mention too.
Toda Racing:CAUTION:TODA Racing has done many checks and calculations for its light weight pulley kit so that the revised ratios allow the charging system to supply the basic amount of electricity required to run the engine under most conditions and charge the battery. But please understand that in worst case situations the battery may become drained.

Often these pullys are not just lighter weight, but larger diameter. That means alternator spins slower than normal, so its less parasitic loss of hp, but also less charging current generated.
If you're driving around say, on the highway, using fan, radio, headlights, etc, you're probably still fine. Stuck in stop and go traffic fan at full blast, radio on, headlights on, well then maybe you have a problem. Alternator might not be able to keep up with demand.
Honda had to make sure everything works in every conceivable scenario. Like how the throttle body is heated so you don't get ice forming in intake when driving at like 20 below zero. Not all those design compromises are needed by every owner. So sometimes you can achieve a performance gain by living without a design criteria the Honda engineers were forced to deal with.
If high current load at low rpm for extended periods of time is something you can forever live without, performance pullys might work ok for you. Not sure how much gain there is though.

I ran the T1R pulley kit for several years with a smaller battery and never had an issue , and almost 90% city driving. I don't recall if the alternator pulley on the T1R kit was a different diameter as it used the factory belt, or if it was just lighter.
