Crankcase evac question

I'll give you my take on them since Stock and Super Stock is limited to a collector probe vacuum evacuation system . ….Pumps are not allowed.
Everyone I know who tried an electric pump has eventually put on a belt driven system . much depends on displacement ,rpm and ring packages.…...Most electric pumps seemed to only pull 4-8' of vacuum at higher rpms.
I know most of my S/SS friends would love to pull that much vacuum with a header type vacupan setup .
bottom line is ,its probable better than nothing or a vacupan setup . especially for a mild lower rpm engine.
