Ok guys let's discuss some of the different ways you will be cooling your Tomahawk builds. On ours we plan on running a radiator mounted Meziere and no front cover. I started thinking about high rise intakes and the coolant passages on the cylinder heads. Let's hear some ideas.
Mine will be reverse cooled. Radiator mounted Meziere into the front of the heads then out the water pump holes back to the radiator. I want the manifold to stay free of anything that obstructs from it's natural beauty
Gary did you have the ports welded up on the heads? Also are you going to run a line between the heads in the rear or not? Is there a good argument to running it reversed?
Let's open this one up, in regards to repeatable power levels what's more important, overall engine temps ( assuming not above 210 F ) , or cool fuel passing thru the Carb?
Overall engine temp would do more for repeatable consistent power. Cooled fuel would just increase power but not make it more consistent pull to pull or pass to pass.
I've always bought into the idea of cold intake, hot oil pan. In theory the aluminum block should dissipate heat quicker than iron allowing me to focus more on cooling the heads. In reality I doubt it really does anything for my application other than simplify the plumbing by not having to put anything on my intake manifold.
Are you referring to welding up the heads where the push rod opening is cut through the water jacket in the Stage 4 heads ? Marv.
Yes if you're running a custom intake and not planning on running coolant though the intake. Or would you build the intake to cover the port? If so would sealing it off suffice?
Yes I am fabricating a custom intake and it looks like I will have to weld the heads up to seal up the push rod openings and re-machine them. Marv.
My $0.02 worth, I would consider plugging those areas such that there are no pockets for air to get trapped in or figure out how to vent those areas like the aftermarket LS Head vent systems do. Last thing you would want is steam pockets or worse, cavitation and erosion. The LS is also reverse cooled.
