Is this more an issue for guys with headers? Why do some guys get away with full open yet others are constantly blowing gaskets. Both my boats had a ball valve wide open and never had issues. One had logs, the other (current) has Mercruiser center rise manifolds.
The reason the valve "can be" wide open on logs and risers is because the risers each have numerous ports for water to cool the exhaust. There is a lot of volume. That does not mean they can't work "better".
Also, logs are the only system I can say it's acceptable to run a thermostat kit. Basically because the water is preheated with the exhaust.
The idea I have been basing this on is to get the water warm before it goes into the block, headers or logs. This will allow moving more water in the system and making the temperature within the engine more consistent, you should be able to realize less than a 15°F differential between the entering and leaving water.
This is huge compared to the more than 60°F we normally see.
The pressure being more consistent will keep steam pockets and flash steam at a minimum.
By controlling the pressure before and after the engine, there is really no way you could over pressurize the system, this will also really stabilize water temperatures.
This will be a one time set up and should be set it and forget it.
Big horsepower will be able to be controlled add well because the valve is the same to what I can tell, is about 1,500 hp. After that, there are too many variables and the math gets funny.
Keep in mind the system is so adjustable that virtually any fuel can be used, although I used gasoline for the math.
Another thing to think about, the better the system is set up, the quicker the system warms up and the engine will be much happier.
This allows you to get a little crazier on the tune (read more hp).
I have been stupid busy at work lately, but wanted to let the cat escape to keep me motivated.
There are literally three moving parts. Should be very robust.
Thanks guys.
