Would it be safe to say that using something like lock tight would be good for that? Just asking so I know when we get mine back together if I should use it.

was the nut torqued to factory spec??? sorry to see your misfortune..
i had a simliar problem on one of my builds. the piston ring came out of the piston and locked up the cyinder causing the rod to see daylight

i told you guys not to break anything. on the bright side... it looks like the intake manifold held up at 21psi..lmao.
also.. i know your using an emanage ultimate and pushing it to the limits, but dont you guys think that the factory throttle body would be a huge restriction too?

You can see the nut inside the pickup tube here.....
This confirms what I said before opening the engine. The problem was caused by lubrication failure but not because of the higher rev limit as it was caused by the oil pump failing to work because of the nut that is supposed to hold it.
The sad part is the crankshaft is damaged but salvageable and the K1 connecting rods are OK. We will keep you guys informed of the next step as sonn as we decide what to do. We might resize the cranksahft or install a new one. We will see....

that is very sad to hear of the oil pump failure.
did you shim the Oil Pump ?
or just left it stock ?
i have damaged crankshafts in the past.
i would suggest you to just change the shaft.
but too bad to hear of the engine damage.
hope you assemble fast and rach your goal.

... Some people have bad experiences with reworked crankshafts and not to lie to you I considered changing it but this crankshaft is knife-edged and that is some money that will be lost if we change the crankshaft that could be saved by resizing the same crank!!!Pito

Here is the Dyno graph ploting the graph from the old engine and the new one!!! Remember I didn't had the time to finish the tune. I was working with the fuel map modifications needed to raise the rev limit in a safe way then tune for RAW POWER 
And this is the car after a little face lift it received before going to the dyno!!!!
