There's a couple kits that will fit the 5.4 Raptor. I believe Roush, Whipple, and Edelbrock all have a Roots style blower kit that will work. Try giving JDM
JDM Engineering or Livernois New - Livernois Motorsports - Home a call. Either can probably answer all you questions.

Thanks pirate air for the help.

I'd go with an edelbrock eforce supercharger for a 5.4 L engine. Google it.

I'll check it out, thanks
