Not to compare but I got 300 passes on the first engine but that was only 9.5’s to 9.8’s in a 3600lb car (with driver). After the refresh from Bobby at RPE I got another 150 mid to low 9's. Bobby tore it down and the bearings were fine. The heads had given up the farm from heat cycles after at least 450 runs (we don't know the history before that). We tore the engine down last season not because the engine was giving us trouble (still running 9.2's at 150) but we wanted to step up and be more competitive in TSO. That new engine goes in tonight!
