 That escalated quickly! Time for break-in!  Took #minimumpsi to BMW of Manhattan to handle some paperwork. Even though it wasn't a BMW it still raised some eyebrows!
 Another built motor F80 going together this week. Maximum PSI forged rods and pistons, keyed crank hub, ported head. Pure S2+ turbos, SSP spec X clutches, full fuel system.
