correct my statement i know of 2 now that come apart and i recall Harry saying it was the same wheel while he was fussing at me.
a different turbo builder had said the 52 was different but i think he ment the compressor side.
i believe they have the same problem just at a little higher power range due to the compressor flowing more.
you all would be shocked if you had any idea how many of these wheels are at garret right now.
2 of mine have been and are back now but they havent released any report yet but i know for fact they have plenty of them and they are steadily coming in.
