both have the same pressure ratio so the maximum boost that either can make is 1.4bar over atmospheric
the R1320 will reach maximum boost quicker than a R900 but you can compensate by spinning the R900 faster and the larger blower will also consume more power to produce the same level of boost
when we did our initial analysis we concluded the r900 is the right size for a 2 ltr engine

Thank you for the explanation, I would not have known the difference.
