Anyone installed pullys?

Has anyone put AEM underdrive pullys in? any tips or tricks? Thanks.

I've heard a lot of bad things about lightened pulleys. Like they make your motor spin faster or something and its bad I forget exactly.

what exactly are you putting in, an underdrive pulley or a true pulley set? And there's nothing wrong with lighter pulleys, I just bought one myself.

does the pulleys add hp? and how much? is it worth it...let me know

thanks guys

do not replace you underdrive pulley! it will destroy you engine. But for a regular pulley set the pros are added hp but the downside is dimmed headlights from what i hear. do a search this has been discussed in past threads

AEM's are good. My friend had a set on his Accord. It didn't make an enormous amount of power but it surely made a couple.

This may help installation (http://www.advanceautoparts.com/howtos_tips/automedia_html/pht/pht20001101pp/index.html?page=/howtos_tips/automedia_html/pht/pht20001101pp/pht20001101pp.htm)

It's perfectly fine to replace your underdrive pulley. I just recently bought an oem one from an ITR that has no PS or AC, much lighter.
