Message: [QUOTE="Blown262, post: 1254044, member: 22334"] It's strictly a mod for fun and stupidity. Nothing more. As for the RPM, that's what this post is for. I know these motors can spin to 3800 all day long. Most diesels I've dealt with are under stressed for longevity. I've seen cummins motors near 5k stock blocks. I'm curious to see what the max rotation speed is on these. Piston speeds at 3k rpm arent very fast so I can see these being able to turn a good amount of rpm safely, I just want to know what the threshold is where it starts to come apart or slap valves [/QUOTE]
