Pulley Upgrade

Thinking about a pulley upgrade from ecs tuning. does anyone have any experience with these? know what kind of hp increase it might produce?

There really more for looks than power. It slows the speed of the pullies freeing about 4-5hp...... not really worth the 250 unless you're trying to get alllllllllllllllll the hp out of your car. And have the cool silver or red or blue pullies that nobody alse has!

I really like my Unorthodoxy pullies they replaced all 3 pullies and the VR6 revved like a mofo in 1st and 2nd gear after they were installed. Then about 6 months later I installed the autotech 10lb. lightened fly wheel and damn the 2 combined are awsome. Ok when you just want to drive around town normally 1st and 2nd aren't bad at all yeah with the LFW you will need to adjust your take off but that's no problem. Ok when I want to get on it 1st and 2nd gear go by very very quickly and whomever I am racing I go by very quickly.
