If i change my cams lift from 9.1mm to 10 or 11mm will this make a large turbo spool faster, or earlier? if so by how much ? a hundred rpm, a few hundred?

is there a negative effect/s to having 10 or 11mm cams?

what duration cams will I need to hold a power curve that increases up to 9200rpm ? 280/272 or 290/280?
