The cams for all the SC's and 3.2 Carrera's are the same, they are just timed differently. The 3.0's were at first timed for higher RPM power, later SC's for low RPM power, than the Carrera split the difference.

As Don said, the larger the number seems to make more low end HP, the smaller the number the more power will be made at a higher rpm.

Thus, if you are building a track car, running a larger K29 style turbo, and have proper fueling mods to support it, you could go to .1 and pull power to red line. If this is the case there are better cams for this including the C2.

Most are going to be happiest closer to 1.7 as this helps get you to power faster.

Also, the spring height is supposed to be changed to increase seat pressure to handle the more aggressive ramps and or upgraded springs should be used. It is also good to have your rocker arms resurfaced when going to a renewed cam.
