The stock crank pulley has vibration dampening material. The underdrive crank pulleys don't, that's why they are potentially lethal for your engine.

Only the accessories pulleys give some safe little gains

Since this thread is about pulley's, are the AEM's power pulley a good choice or is there something better?
