Stock sized lightened crank and alternator pulleys for the 2.4L LD9 are now available! These are great for people looking for all the advantages of lightened pulleys but none of the disadvantages that come with underdrive pulleys. Less rotating mass, quicker revs, and no loss in power generation or supercharger speeds.
Read about the development here (long but interesting at parts):

Buy the set for $165 here (or buy them individually) here in the GP forum:

Enjoy!
heh. If I see those red ones in person, I strongly suspect I'll be kicking myself for not getting them.
Just can't win here...
