Just curious of the better si trim choice for shooting for 650whp on a 363. A v1si or a v2si? Which can be turned harder?

Per Vortech, both have MAX power of 775HP, max flow of 1150CFM, and peak efficiency 78%. V1 has max RPM of 55k and max boost 26PSI. V2 has max rpm of 52k and max boost 22PSI.

And of course a V1 will be a bit louder than a V2.
