Compressor inducer to housing clearance?

Does anyone know what the minimum and maximum radial compressor inducer to compressor housing clearance is supposed to be on an s300 and an s400?



My s363 touched off just a bit, but the bearings are still good (.0015 clearance) and the shaft is straight. I'm thinking about opening up the clearance on my 366 before I install it.





Thank you!
