WTF has been done to my turbine wheel (weird blades cut)
I have a IHI RHC7 turbo on my RB26.
I removed it last week because I need to fit a bigger turbine housing. The one that was bolted was really tiny.
So I removed the old turbine housing and discovered that my turbine has a weird blades cut. It's not a cut back or clipping. The cut is done at a different place.
A portion of the "major diameter" area working at the inlet side has been cut to be now the same diameter as the "minor area working at the exhaust side.
So we can conclude that there is an area where the blades of the turbine are now NOT tangent with the turbine housing, where the diameter is progressively reduced.
WTF is it intented for?
What effect does it have on spool up and top end?
Here are pics of my wheel and pics of a stock wheel.
Please, Turbo gurus, help needed!
