General LSX Automobile Discussion - -12 an cooling hose
05-29-2012, 10:47 PM
ok, so I have a meziere pump and griffin is building me a custom radiator. I planned on hooking up -12an hose to the meziere pump. Is this coolant hose too small inside diameter to flow coolant properly to cool 1000whp? The pump will be constant ran any time the key is on and the radiator is specifically built to cool using this setup. I am still somewhat concerned since I only find people running double -12 lines. burkhardt front bumper supports have an afco cooling system with remote meziere pump running dual -12. I am not running a thermostat so I was hoping the smaller inside diameter will help restrict flow and keep the vehicle cool. Let me know what you all think.

anyone? anyone at all?
WAY TO SMALL. Stock hose size it 1.5" to 1.75" at 300 to 500 HP. -12 is at best .688 ID and 1000 HP.
Are you planning on driving this on the street or is this a drag only car? Are you planning on -12 for the inlet and return?
If this is a street car i would reccommend that you keep the stock size hose and run a 55gpm pump.
If this is a drag only car then i recommend at least -20 on the inlet(lower rad) and -16 on the return(upper hose) and a 55gpm pump
If you need more help call Jerry at Meziere 760-743-3273

kinda what i thought. I have the 55gph pump race version. My only reason I have questioned it is the inside diameter of a thermostat is the flow restriction of any system which is at best 1'' inside diameter which would be -16. That was my thought process. and yes its a street car. Last year I used a 1.5'' hose and had no issues. just trying to stay braided with everything now.

i'd rec -20 lower -16 upper as well. just put this on a 602bbc with a 101mm and stayed cool on the street in OCMD cruise traffic a couple weeks ago
