Mahle Piston Rings
The Mahle 41422CP has been my ring of choice for my 8v turbo builds in past years. The sets are plasma-moly ductile iron. Mahle has also had a "standard" ring set for the 8v turbo available, 51422CP(plain cast iron). I recently was informed that the 41422CP ring sets are no longer being produced by Mahle, they are discontinued. The Mahle catalog now shows 41286CP rings as taking the place of the 41422CP rings. This comes as a surprise to me because the 41286CP ring has always been the "premium" N/A engine ring set. Those sets are plasma-moly cast iron. Which in my opinion would still be better to run in a turbo engine than the Mahle catalog listed, "standard" 8v turbo 51422CP, plain cast iron rings. Any thoughts on this matter people?
