For those not on facebook: The post says it was crank number 2 that broke like that. Power is probably not the underlying cause...
That picture that tryingbe posted is from my omni. 2.5l it makes good power indeed. But not a record maker buy any means. The 1st crank the key was clearly moving around and cracked the snout. The 2nd crank did almost the same thing. I had. I've confirmed crank bolt is not bottoming out. And have now had the crank pulley balanced (tone wheel missing a tooth for megasquirt) well see if it lasts...
So you broke two of them which had the modified pulley for use with megasquirt installed on them?
The 1st crank snout did not have megasquirt tone wheel on it. I noticed my alt belt getting beat up and not keeping adjustment. The 2nd snout started wobbling enough to start hitting my crank sensor.
