hmmmm pulleys seem like a good mod

I have got Brents pullies and waterpump combo. Im gonna be the bad guy on here and say that dont expect to feel any seat of the pants difference with the pully mod. It just doesnt happen. (at least on my car it didn't.)

But my thinking is, "Over the long haul, every little bit helps."

when i had my pulleys installed i felt a difference for like an hour then the car felt the same again, the throttle response felt better alot tho even til now

The only dyno I've seen for pullies was a whoping 4 hp, same for the meizer.

I think because its 10hp and not 100hp you will not get that thrown in your seat feeling as I read on earlier on this post. We are only talking about up to 10hp here. The reason you dont feel it now or as you say "it felt normal after an hour" is because you get use to it and your body does not remember what it felt like before. Bet anything that the day you take them back out and put the stocks on again you will feel what difference they made.

When I removed my cai and had to return to stock to compare I kept saying to myself why does my car feel more peppy than I remember? Then it hit me, I still got the pulleys in there that I did not have when I was at stock before! Would not go back for nothing. Very cheap way to get some extra hp when you think about guys who put on the shortys for similar hp but cost much more.
Not bustin chops here, just letting the guys know who dont have these yet that you will notice it when you install them and most guys dont stop noticing afterwards.

My Dealer made me remove the pulleys so that they could diagnose a engine code I was getting. so warrenty is not voided if you remove them. the problem is that most techs dont know how to diagnose using their brain, all diagnostics are done using a book so any anomolies like pulleys or air intakes introduce a possibility of failure due to the aftermarket part. A dealer can't void your warrenty due to aftermarket parts, although they can refuse to work on the car. Aftermarket parts can add as much as 3 hour labor to the diagnostics of a problem, Ford will not reemburse a dealer for these hours. So be prepaired if you need service that you may have to remove them.

True, My Roush Pulleys state 12hp Gain, but my Dyno only shows 5 hp, so maybe they are stating crank hp not rwhp???

That sounds realistic.
