I'd suggest a positive displacement Roots type such as the Kenne Bell, Holley, Roush or WhippleCharger. They make power at all RPMs vs having to rev the engine as with Paxton or Vortech. Torque is king. All make good power, but the Roots type makes usable power at all RPM levels.

There's a reason OEM manufacturers go with these vs centrufigal. I had a T-bird SC that we drove for 188,000 miles without any trouble at all from the blower. My Roush Mustang has tremendous power with its Roots blower.
