Underdrive Pulley Set Worth It?
Read a little on here afterdoing a search, but there isnt much info on these. Are they worth it? Any noticable power?
Also I plan on lifting on 37's somewhere off in the future, and I noticed Troyer said there were some problems with this. Should I wait tell then?
Thanks!

Underdriver Pullies are a good and cheap way to make real power. There are a few things I have learned first hand concerning them.
There are two types. All in one, and "Piggyback" The piggyback type are often a bit cheaper, but require you to place your factory harmonic balancer back on. If you don't you risk serious damage to your engine. The all in one have a weight or "mass" that function as a ballancer.
If you do decide to put them on, I would recommend swapping out your OEM oil pump gear for a billit one. The oem's are pressed metal, and are prone to braking. Billit gears are a bit pricie, $250 - $300, but it adds a lot of piece of mind.
