testing unknown pump power?

This is the first setup I'm building and I've just aquired a 12v pump that looks like it should be good, it's a heater core pump for a jag.

Is there a good way to test this thing to see if it's any good?

I've pluged it into a 87amp psu (not the one I'll be using) and it works but when I stuck it in my sink during lunch today the water doesn't fly out like I thought it would. (5v=trickle 12v=flow) it kinda just flows though the 1/2 barbs like when you pour a Mountain Dew or milk. Is that normal? I didn't have any hose to soo if it has any power to "push" the water up a few feet or not.

Thanks for your input!

That doesn't sound like too strong of a pump, but in order to test it you'd need a flowmeter. Flowmeters are generally expensive. So it'd be cheaper for you to just go and try and find a Maxijet 1200. I remember getting mine for about $20 which is a fraction of what my flowmeter cost.
