underdrive pulleys?

I would like to know if the underdrive pulleys are a good idea? Can someone that is using one please let me know of their experiences with it. I am looking at the crank pulley and the alternator/power steering pump pulleys. I would like opinions on both please. How was the power improvement? Anything negative about them?

Thanks

IMO just get the AEM underpulleys. don;t mess with the stock crank pulley. its balanced by honda for a reason. no need to mess with good engineering

IMO don’t get pulleys, spend the money elsewhere. Just take off your PS belt for a few extra ponies.

I was just wondering because they claim 8 Hp and 12 lbs tq from replacing the crank pulley… not bad for like $150

Not worth it. Those numbers are probably false too. The stock crank pulley is not to be messed with. Just ask some knowledageable, they’ll agree.
