  • CAT 3, N4, vs W cams

    How do these cams compare?

  • #2
    One thing I find hard for me to accept is, a cam with 256 degrees of duration being a street cam. For automotive applications that would be considered race only. I guess a cam like a cat 3 or n4 is perfectly street able in a v twin. Maybe because there isn't a automatic trans torque converter to consider.

      256 is mild. N4 are a bolt in . Good street cam.

        The Cat 3s make about the same power as the SE 536 cams. In an equal build the Cat 3s will make about 5-8 more hp than the Andrews N4s. The Ws are really not comparable as they do not do well with the 10.5:1 compression that the Cat 3s like. But a comparison of N4s and Ws with 10:1 cr shows about a 10-12 more hp with the N4s.

          I think I'll go with the fueling 505/515 cams. Duration between the N3 and N4, 505/515 lift, wider lobe separation angle then most cams should provide a smother idle. Fuelings site shows 90hp at 6500 from a stock head 2008 1200.

            I do sell the fuelling cams $310 if needed.
