Interesting scarbs, funny there is no ban on DLC, would you have any idea what the oppsite surface in the liner could be?scarbs wrote:Yes JA is getting a little confused there.

To be precise was the interior and piston crown also coated with DLC? What was the general color and was it uniform over the complete piston.

Have you heard of anything better being developed?xpensive wrote:Interesting scarbs, funny there is no ban on DLC, would you have any idea what the oppsite surface in the liner could be?
No, just any knowledge he feels he can make public. This is stuff the average racer has access to these days IF he knows what to ask for.xpensive wrote:You want fries with that...Brian?
