using lighweight pulleys r about 2lbs less then a stock pulley so it puts less load on ur engine, frees up a free hp if you modded, and helps u rev out faster,
based on way mods i see u hav and r goin to get, a lightweight pully will give u a little gain and yes u need a shorter belt but its just a little short, but do this add a last mod b/c price/power ratio u dont get much

By having them lightweight the engine has less of a load to try and turn. This allows the engine to spin faster thus quicker revs and with less of a load more hp(very little tho). Do it more for the revs so you can get to your powerband quicker and thus faster 1/4s!

the gm drag cars run the super damper with no problems up to 1400 hp.
it is already balanced and can with stand high rpm abuse.
i dont know as to how much it weighs but its better made than most
costs bout 410 through summitt racing
