I have a 2005 mustang GT and I need some help to find a used whipple or Roush TVS supercharger setup. Ive been wanting to supercharge my car for a while, but the prices are a little high. Im thinking TVS or Whipple superchargers, because they give you the room to expand your horsepower capabilities for the future. SO please help me. Price range is $3500-$4000. Please keep a look out.
