Machined out turbine OP6 housing on Hybrid ..
I got the my OP6 hybrid back from the manufacturer but wasn’t too happy with how they machined the hole for the larger wheel.
For some unknown reason they did not machine right through the housing and left a 1 mm sharp edge on one side.
I think it will not impact the performance but on the other hand I don't understand why they left that excess material?
I see soot build-up on that edge right away
Any input welcomed!
