As nite b has said.. it all depense on the engine....
a 60-1 will flow more boost than a standard engine will handle..
spooling... well if you have a well sorted 1 - 2jz ( as one of my customers has) it could spool before 3000rpm... but if you had a 4efte with nothing done to it it could spool at 9000rpm....
and it also matters what is on the turbine side... standard TB03, stage ? shaft, O or P trim .48 to a 1.32 A/r turbine housing...
a 60-1 is just a name for the compressor wheel and nothing else...
(the above mention 1.5jz was producing about 430kw @ 6500 Rpm
spooling @ about 3500rpm on 24psi of boost, it use to spool before 3000rpm with a smaller turbine housing.)
