If I were plaing on going with a KB supercharger, and was not going to build my bottom end right away. What would be the best to go with? I plan on upgrading power as funds become available. So what would be better? Start with a "S" and if I run out of steam with the "S", upgrade to "H"? Run the "H" below optimum effiencency until I can afford to build the bottom end. Thoughts?
