go to hpfreaks.com and go to turbos. Look up the boss 550, that will give you your answer ;) I don't know the specifics of it, but I believe he is running the big shaft Dual BB version.

I looked on hpfreaks could not find it, still no specs on the allmighty "boss 550" turbo. If Mike sees this can he please tell us the HOT & COLD side trim and also the housing A/R because it appears to be huge and im very curious!! THANKS!!!!

THX, looks like housing is .83 A/R , compressor wheels range in trim size from 50 up to a 74. It does not tell what the turbine wheel sizes are
