Right, just tapped a 1/8 NPT fitting through the plastic. No more bleeding the bubbles out of the circuit either. I removed the big shut off valve for the NW CSK and capped the reservoir outlet. But, someone could pipe this in after the valve too. The way I have it I can run Engine Ice (snake oil) or just plain water and it can't be mixed with the engine coolant.

Kolevski, sorry for the hi-jack LOL!

 

with my super cooler design I dont have a resourve as the tank has 3/4"of air at the top and thats enough for expansion of the fluid, FYI. Woody

I believe the picture of the BMW tank shows it without the cap for demonstration purposes.

 

Right , it is just showing the bleeding action. Super cooler is on my wish list!

 

No need for apologies Tuna it's all interelated I quite like your design.

Woody do you ever get overflow of coolant or get told off by scrutiners at drag races for having a hole in your cap?

John.

 

Can't have any fluid on the track....or chance of any overflow...is the overflow caught, or am I missing something here...I really don't have a problem just using the seperation kit...but, I not consistantly running mine like the round tracker's do either...

 

The only way to loose coolant from the super cooler overflow is to boil the water. The hottest I've seen is 175º and I probably use my car harder than 1 out of 1000 do. I run straight water with chill charger. No problems with any tracks so far.

Youd have to know there is a hole ( its small and looks to be one of the letters in the cap) , and if it dont leak its all good. Never get hot water so boiling is not an item to worry about, I just need enough expansion to adsorb the molecular expansion as the water expands well below the -its - boiling point.

Enjoy, Woody

Did you ever use the pump you bought and what were the results?

 

He has not posted for two and a half years, so do not hold your breath waiting for an answer.

 

Good point 180

I am installing a killer Chiller & am upgrading my johnson cm30 to a cm90 pump.
The system will not be pressurized & will be free flowing. I also have rudys upgraded intercooler.
I would like your opinion on flowing that much volume thru the intercooler

Thanks Barry

 

If we accept the fact that it is the constant flexing of the IC that causes the leaks then we should recognize that the greatest flexing will occur when the IC coolant circuit runs without any pressure in it. The air pressure coming from the SC will fluctuate depending on its speed, so the aluminum sections will compress and relax the most without internal pressure being present.

If the pressure inside the aluminum sections was at the pressure normal to the hot engine we could see a different pattern of expansion and relaxation, We would see compression when the SC pressure exceeded the engine coolant pressure and expansion when the SC pressure was below engine coolant pressure.

Running the IC coolant circuit closed would be somewhere between these extremes as a small pressure would be exerted from within when the coolant got hotter.

The ideal design would be to use round cooling sections rather than the ones used. The trouble being surface area loss. Round sections suffering the least deflection due to external and internal pressure. Irregular sections suffer the most in the above situations due to a concentration of stresses in certain areas due to the irregular shape. Irregular shapes also suffer from poor turbulent flow, having areas where laminar flow occurs, turbulent flow sweeps the side walls with the majority of the coolant and therefore carries away more heat. Laminar flow just goes straight through the lines more of less with no sweeping action and thus the only the fluid close to the walls picks up the heat, this results in the coolant exiting the cooling area carrying less heat.

Is it best to run the IC circuit with or without internal pressure over the long haul? I'm not really sure. I tend to think that a IC circuit with normal radiator pressures in it would be best.
