As Pete has said it depends on the Sportcruiser spec you are talking about, for instance the Pipersports are all Rotax and have ground adjustable fixed pitch props which will have totally different performance both in the cruise and T/O and landing to the wobbly prop versions.
There are also 2blade and 3blade CS prop versions and also a few Jab3300 engined versions out there.
I have a Rotax powered S/C with a 3blade Woodcomp CS prop and operate very comfortably out of an undulating 500m strip. Take off at MAUW is usually around 200m and I am comfortable going into any land away strip above 300m.
Hope this helps.
