With anything above 7psi we highly reccomend to key the crankshaft to the balancer. 12-15psi would spin the balancer and cause damage to the snout.

My engine builder did not key my crank, or pin it, and now I'm left beating my head against a wall. Everybody should read this story and learn from my mistake/lack of knowledge about what was done to my motor. It's back running now, keyed/pinned/ and 100 tubes of lock tite!!!!!

I pulled my bolt out by hand from not pinning it. Good thing the balancer was still intact. Definetely get it pinned quick. A broken belt can massacre your engine built when it gets out of line.
