im thinking divider would be to send water were it needs to go not all to one side just my 2 cents.

I say take it out. What purpose could it serve. The water is coming out there to go to the rad. No reason to divide it.

dirtrace, i'll stick to my restrictors. i use a 3" crank pulley, a 6" water pump pulley on a 550+ HP engine on gasoline and no overheating problems. my "real race pump" is a ford SVO pump and it has restrictors built into the backing plate. i trust the ford engineers...

there's no reason to spin the water pump any faster that what's necessary to cool the engine. it's a waste of horsepower.

went back and re-read one of smokey yunick's books (power secrets) and i think the reasoning for this divider is due to some of the results of yunick's early cooling test work (remembering this book is from the 80's).
as the coolant flows from the back of the heads forward and up through the manifold at the front to the thermostat outlet, there is a pressure difference from on side compared to the other so the coolant doesn't flow equally from both sides of the engine into the one outlet thus reducing flow from one side of the engine. some of you would remember yunick's home made plumbing to correct the problem where he drilled and tapped into the front of the heads and plumbed with a y-piece. so my guess is that was the intent of your manifolds designing.

Why attack me, the first line in my post was real race pump builders. And it wasnt directed at telling you what to do with your motor you didnt ask the ?.

"i trust the ford engineers..."

All I know for sure is that when I went to the Stewart Stage 3 pump, no restrictor, 1:1 pulleys, I was instantly cooler 30 degress on a SBC. I have no idea about Fords but to say you trust the Ford engineers??? Isn't that what people who used to drive and burn in Pintos used to say??
I sure would not blindly trust any car manufacturer...they are to sell products, only an engineer would put some of these oil filters, sensors, etc where they are at, they obviously don't have to ever get their hands dirty.
