I am not saying you are wrong since I don't actually know chit about turbochargers in the grand scheme.
A single s475 can make 800hp+ in a single configuration but in most compound setups things get out of control in a hurry as far as boost numbers and heat before you approach that number.
Is it because of the restraints on the secondary used typically in s475 setups? An s363 over an s475 vs maybe an s366 over an s475 for example?
I have to say compounds definitely appear to be harder on parts as well. Transmissions, rods, cranks, etc. appear to suffer with the low rpm power compounds usually present.
JSP has posted a good example of compounds vs single in the past. In his 364 over S480 it made 1000whp, pulling the s480 out of the compounds and using it as a single netted him the exact same 1000whp. The compounds definitely had a broader powerband though.
