I'm seeing rapid bearing wear with track use of a 525 kit with optimal cooling on a standard S54 revving to 8k . I'm running a 34 row Setrab oil cooler and a larger radiator to keep temps to the 240's on track . Its every 15k bearing replacement at my power level and heavy track use . With the stroker and boost there will be no need for 8k so you won't be missing anything .

Did I just read that right? You're having to replace your rod bearings every 15k miles?!
