For the sake of those who are unknowledgeable about high performance engines and about S/Cing in general, who might also be considering the possibility of S/Cing their cars, if I were you, I wouldn't merely pay attention to any vendor's claims, nor to any vendor's customer's claims w/out regard to sources that are neutral on this topic. And that's why I decided to purchase and read three books on the subject of Supercharging STREET cars before I made my choice. The best book that I can recommend to people on this topic is titled "Supercharged!" written by Corky Bell.
And for another UNBIASED viewpoint on supercharging your STREET vehicle allow me to also suggest the article in a car magazine such as the one that's been posted in a "sticky" thread by one of the moderators of this board. And infact here is the conclusion that the magazine article draws, and this is a direct quote about how the choice of S/Cers was summed-up by that article. Look at what it says concerning different S/Cers in different vehicles:
"Today there is a huge number of blower kits available to Mustang and Lightning owners. The choices can be overwhelming, but we've found that picking the right blower requires nothing more than a little research on your part. The key to finding the best one for your combination is to select a unit that can supply the most efficient level of boost in the rpm range that you're building your engine for. In addition, consider the combination as a whole. For instance, heavier vehicles need more torque than lighter ones do and that's why the Eaton, Magnum Powers or Kenne Bell is the best choice for a 4,500-pound Lightning. But a Paxton, Powerdyne, Procharger, or Vortech may be the way to go for your 3,000-pound LX".
Let me remind you that the above words are NOT my words, they're the words of "MUSCLE MUSTANGS & FAST FORDS" magazine.
