This is for a C6 Zo6. I have seen models around for a racing higher output water pump. Not an electric pump. However I can't get any figures regarding GPM output or these or the stock water pump. does anyone know? Also who sells these? Thanks.
evans and edelbrock both sell high flow water pumps that would work
evans has an extended pulley and edelbrock requires a new pulley also
evans flows ~35% more on restricted and ~100% more unrestricted during independant testing
dunno about edelbrock, but they are quoting a ~25% improvement
all at the same RPM
evans has a steep price though
edelbrock is expensive, but not too bad
also, all the above pumps and the stock pump could be pulley-ed smaller, therefore flowing more

Thanks for your response. I finally found Evans in a Thunder Racing catalog. It looks like I can do much the same thing with just a pully, and new belt, and save alot. Think GM carries those items? Haven't seen them in a catalog.
