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.


650/670 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, large cam, and spins up to 8000 rpms
