I know! I know!
You will want to get your self a smaller pully. This will change the gear ratio to make the supercharger spin faster. This will produce more boost wich = more hp.
The pros? You will be making more power, so you can go FASTER!
The cons? By increasing boost pressure you will also be increasing intake and combustion temps. These increased temps are "more likely" to produce detonation, wich can cause severe engine damage.
You would also be more likely to run into a warrantee issue if you had a problem.
That said, there are many Lightnings and non-Lightning supercharged F150's using smaller pullies. The Lightnings have a motor designed to run with boost. It's pretty strong and I think can handle a few extra pounds without a problem. The standard Triton engines were not designed to run with boost but are pretty strong too, though I think would be more likely to have issues related to the supercharger.
If you have a Lightning or '02 supercharged Harley edition you probably should check out the Lightnings section. There are a ton of speed freaks, from mild to wild. They should be able to get you informed. If you have added a supercharger to an F150 then you might want to check out the superchargers section.
You can deffinitley get more power with a different pullie. I think that reading and asking questions on these message boards will help you to make a change without running into problems.
I am not an expert, I just have time to sit here and type. Get many opinions and see what you think then.
Have fun!

Yep... a smaller pulley will give you a bit more boost, and power... but many supercharger warranties are voided by adding pullies such as these. If you're running a supercharger on a stock F-150 engine, I'd avoid going above 9 pounds, as any more will cause serious problems. The engines do have forged rods, but like anything, they will break under enough stress. Make sure the rest of the drivetrain will handle the added hp/trq. before you upgrade the pulley. If it will, then by all means, do it and hold on to your a$$!!
