Billet wheel
I think the billet S480 is rated at 1300 HP.
Here is a good reference.

If the company doesnt push the design of the wheel and just copies the cast wheel in Billet, then of course it wont gain anything. Joses wheels are a completely different design. They have provided a 250 rwhp gain over the cast wheel in an 80mm S400 application.
250 rwhp for less than 500 bucks. Few things in hotrodding have that much bang for your buck.

As far as cast vs billet... billet wheels weigh less, so it takes less to move them, which helps spool.
Like Westtexasbuff said, from what I read Turbonetics offers a billet wheel in all their turbos.
