What carburetor is right for me?

600 cfm: This 4 barrel we would use for 95% of the VW engines for Draw Through, Blow Through, and All Motor with a minimum size of 1914cc. It tunes very well and has great response when built for Gas or E85.
 
650 cfm: When you need a little more bump from the 600 cfm. Primarily for large engines 2054cc and larger with heads that breath, some decent amount of compression, and a pretty large cam.
 
750/850cfm: All out full race competition use when your engine makes well over 450hp and spins up to 9000rpms. Only available in Draw Through Gas configuration
 
NOTE: All 4 barrel carbs are Mechanical Secondaries
