Underdrive pulley kit
#7
That defeats the whole purpose. The underdrive pulley setups are for slowing down all the belt driven accessories. The alternator spinning under a load is the biggest drag of them all, so you'd just be adding it right back making the investment and time spent not worth it. Unless you're mostly after the "ooh" factor of having billet pulleys.

I've read of quite a few people on ls1tech running a UD crank pulley and an OD alternator pulley, and still have improvements over stock. Some also claim certain brands/kits provide you with a OD alternator pulley.
Doing some more reading on ls1tech, I see a lot people claiming gains of around 8rwhp with a 25% UD pulley. Don't know how truthful some of their statements are, but oh well. Let us know when you install it if you have any issues with it.
