I realize I posted before, but I finished my WCC cooling system and did some more testing. Here's what it looks like:
It has the giant WCC radiator (4" thick) and managed to fit twin Spal 13" 1750CFM pushers in front of it.) There is no puller fan. There is no shroud. I removed all the damming I previously installed as a test. It's as shown.
I'm running an electric water pump mounted low and about 3" from the radiator outlet. Mezeire WP-337, 55gpm.
I'm running NO surge tank. My fill point is my thermostat housing as seen here:
There is no header wrap.
No
oil cooler.
The block is 1/3rd filled with hardblock.
The engine is supercharged.
Aluminum heads.
Not shown is a coolant overflow bottle in the fender that has a siphon tube to the bottom so the system can burp, then draw coolant back in as needed.
Not shown is a pair of 1/4" coolant lines that come from the rear corners of the intake manifold and terminate at the thermostat housing to carry a small stream of coolant forward at all times to eliminate trapped air at the back of the engine should there be any.
Elevated 1500rpm driveway idle test with both fans running; I can't get the engine above 145deg F. I have to turn the fans off to get the
oil warm. If I do that and bring the engine up to 180deg F then turn the fans back on, it pulls it back down to 145deg F within about 5 minutes. Previously, it was running hotter than this...that was due to retarded timing and rich mixtures that created a lot of header heat. Now it runs about 28-34deg of spark at idle (computer controlled, EFI deal...bounces around), and is running a lean 14.7:1 AFR and cooling has become a non issue. I'll let you know what it does on the road; it's had very little trip time thus far...but so far so good.
