LS1-450

Wanted to start a thread to look into any relationship between power (CC pressure) & rod bearing deflection caused crank contact (spun rod bearing).

Please describe your experience. For example: LS6 block, Turbo, XX lbs boost, 6500 max RPM, stock rods (note brand if after market). 552/488 RWHP/TQ. 18,000 miles w/ good oil pressure until spun rod bearing, #8 rod.

Again this is an example, not an actual occurrence. If making good power & have not spun a rod bearing for +20,000 mi, also note the set up.
