Use a ross balancer and trigger kit that I bought late 2016 on my built rb25 ~600hp, dyno work, rollracing, track night and street work so far. pulled the motor out to sort another issue and everthing is in great condition with no issues snout is fine, balancer is fine trigger kit is brilliant so in the short term it hasnt caused any issues like decives older balancer.. When talking to one of the techs over the phone he seemed to think incorrect install and not torquing the balancer bolt can cause some issues. Would not hesitate to buy another ross balancer.
