How similar are the Cossworth M2 cams to the Kelford 272s? I know they have the same lift but I have not being able to find the duration at 0.04 in (1 mm). It is not on their spec sheet. If specs are not available I am mostly interested on which one has a better idle a better drivability. Anyone have used both cams on an Evo 8?

 

I am curious as to this comparison as well. Although I would like to see the GSC S2's included too! Which is better given a 7500 RPM limit?

 

At least the specs for the S2 are on their website. The S2 are a little more aggresive than the Kelford 272. They have more lift on the intake (0.2mm) and a little more duration on intake and exhaust with the same centerlines. Very close but a little bigger. Not sure about the M2s.

 

Way cool! Thanks for that info, Racer.

 

I'd be interested to see but ill take kelford 272's over cosworth m2's anyday.

 

Any reason or hard evidence on that? I am just curious. Too bad M2 were not part of the AMS Cam Test.

 

Someone was going to put both cams on a cam doctor awhile back to measure specs, but I don't know if this was ever done or not.
