Some say a little hp is gained, I think it is more, anyone ever really do a dyno after a pullie install?

8-10 at the wheels, almost guaranteed. especially if you still have the PS.

I just had my ASP pulley put on yesterday and I can definitly notice a low end difference. It get's up pretty quick! As far as upper end, I really don't notice any difference.

I wouldn't listen to whoever told you pullies only give you a few HP. It is one of the best bang for the buck HP mods you can do ![[patriot]](graemlins/patriot.gif)

We typically gain 8-11rwhp on our dyno, so yes, it's a good modification.
Just be careful on the -'93 5.0s. Their charging systems and alternators aren't up to the task of underdriving unless you upgrade those as well.
They do, however, work great on the 4.6s with no other supporting mods.

How difficult are pullies to install and where can you get the ASP pullies I've never seen those before?

Pullies are fairly simple to install and you can purchase ASP pullies from Summit Racing. Does anyone have a stock 87-93 alternator pulley I can have?

I was told by ASP that you will see 15hp from the install. It's more like 5-10hp. You can feel the difference though. They are worth the money. Keep your stock pulleys just incase you decide to get a supercharger later on.
