Eh, not really. They were aimed at building an *affordable* journal bearing version of a GT35R in their era which is exactly what the wheel specs are. The problem came from when they were jammed in small a/r, stock-appearing turbine housings and used at high pressure ratios....spool and response was terrible, airflow production was equally as terrible (compared to the same turbo with ample turbine flow), and reliability was terrible. Back when these turbos were popular and I was still servicing Precisions, something like 8 out of every 10 of the one I'd receive for service in a DSM-flanged turbine housing failed from a total thrust system explosion and/or were missing the turbine inducer due to overspeed from turbine restriction.The knock on these turbos was the poor spool up due to the mismatched wheels
Spools fine I think for a JB turbo on the .63 housing. This is at ~5800' elevation.The knock on these turbos was the poor spool up due to the mismatched wheels
