Interesting new offering coming soon from Comp Cams. Seen reference to DLC coated lifters over on Speed-Talk for BBC. Apparently nothing new regarding use on lifters, but I believe the first offerings from a major manufacturer. Looks like it’s $114.95 per lifter. Racing in a series that requires flat tappets one would assume @ $1839.20 for a set. Only for steel cores though.
A quote: “This wear resistance coating also lowers the amount of power required to run an engine’s valve train, as well as lowers friction, heat and oil temperatures”
Wonder where else the DLC coatings might be used, if the high cost process will ever come down enough to become more prevalent.
