What causes these to break are micro welds developed between the oil pump gears and the crank shaft. This becomes apparent more and more over time and is not caused by over revving the motor. We have several customers who have shattered their oil pump gears with factory rev limits. With that said the above failure was within factory specs. Also with corresponding mods the motor does not run out of steam over 7500rpms this is very evident in builds such as 1slow370 where he revs to 8300rpm on the daily.

So please unless you have factual information to add to the conversation or are willing to be constructive to the conversation I would ask you respect our moderators wishes and our threads. We do not want the unfounded negativity you have brought us and others in the past in our threads.

Thank you
