Thanks for your input

Thanks to all of you for your insights. I am trying to anticipate all potential issues before our first dyno runs. Because our pre-ignition pressure is so high, I was looking for your insights regarding experience with any pre-ignitions stemming from lubrication oil. While our design prevents...

Thanks for your thoughts. We should be running up on the dyno in another month or two. I'll let you know how it all goes. Thanks, Don ---

thread71-215499 We are looking at a 90 Bar (1323 psi) pre-ignition pressure and a 5200 psi peak cylinder pressure. I saw a post regarding pre-ignition triggered by lubricating oil getting pas the rings. Our current design has 4 rings -- oil wiper ring plus 3 compression rings. I am...
