Hey, everyone is entitled to their own opinions and beliefs. I'm just stating mine from my fifteen years experience in rebuilding and modifying turbochargers myself here. Not saying there's anything wrong with a fifty or whatever mile break in. I'm just saying it's not absolutely necessary. I've torn down many turbos that have been hammered since minute one and the seals break in just fine. Biggest killer of seals is too much oil pressure and/or excessively worn bearings/thrust.
