Tex, this general info ^^^ is well known to me...and my other turbo's with clipping done...
...what I am specifically after from John's insight, is his experience with thier SS turbo's and some S3's he's had clipped...
...as each turbo (series of) behaves differently.
John, with you're first hand experience with your SS turbo's and S3's...what of the below Qs can you expand on?
Thanks
Jer

...(2.)and how can you tell if the turbine wheel has been clipped to far?
...also (3.) would clipping the compressor wheel's exducer (only) a bit, allow for reduction of the comp wheel pressures that the 20G-HR has been noted for having at high rpm??
...curious to know??
thanks

Again you can cut the wheels down to take care of those problems.
