As title says, on an ls1 motor? looking at doing a remote water pump and need to know if i can use a 20 gpm pump

 

Try using 'search'.

One I posted = search title OEM GEN under 'external'

 

Stock LS1 w/160 T-stat flows 55 at 5000RPM
flows 45 at 3000RPM
flows 30 at 1500RPM
Electic water pump wo/T-stat flows 23 across

Would not rec anything less than stock for a street car. Also the more power you make the more cooling you need.
