Ahl 4 Posted January 12, 2007 Group N is basically standard production class. Most of the stuff is optimised but within standard dimensions etc. http://en.wikipedia.org/wiki/Group_N The use of Group N Cam profiles these are normally used in cars where the Championship rules specify that standard cam profiles must be used. But the FIA & most other motor sport governing bodies give a tolerance which is usually + or 2 Degrees on the duration & + or 0.2mm on the lift. So these are taken advantage of on special ground profiles that are extremely accurately ground to the upper limits of these tolerances. But unfortunately the gains from this type of profile are very small. In Group N type Championships though, any small gain is always worth having, but for any other competition where such rules do not apply we would not recommend this type of profile. If its a true group N camshaft, then I would take from the above information that it makes no difference worth having. Share this post Link to post Share on other sites
