hughdogz Posted August 10, 2007 Share Posted August 10, 2007 I'm running N/A and the cam profiles are different between turbo and non. Anyone know what the difference would be? I don't have specifics, but I'm pretty sure that valve overlap is less on turbosthan n/a because of reversion from the higher pressure exhaust gasses in a turbo application.

TimZ Posted August 10, 2007 Share Posted August 10, 2007 Just a quick question for BRAAP, what would have caused this dug out groove or indention that's only on the two rockers that were on the worn lobes? I know it's hard to see so I circled the spots that are worn. It's not like it's a slight groove either, it's really dug out. Not BRAAP, but I would imagine that this is the point on the pad where the tip of the cam lobe was contacting at max lift. The radius of curvature of the cam lobe is smallest there, resulting in this being the point where the cam exerts the highest pressure on the pad. As an analogy, think of this as being the edge of the knife, rather than the flat side of the knife. Quote Link to comment Share on other sites More sharing options...
