Modified Canton coolant reservoir
Thought I'd throw some pics up of another mini project I finished last fall. I used a Canton reservoir for an 03/04 Cobra, since I have bins and bins of Cobra parts hanging around. I relocated the inlet/outlet, cut the original bracket off and made my own. The reservoir fits above the belt but below the hood just fine, and I can move it out of the way by removing just one bolt. The intake tube is a tight fit but I still got everything in there.

Color on the valve covers and surge tanks is a high temp powdercoat. Works great on the valve covers but it's a little too brittle on the rough surface of the surge tanks.. can't think of the name though.

The key to cooling these S/C is pressurizing the cooling system. The key is to keep it equal to your pumps flow rate. There are many ways to do this.

The primary benefit to pressurizing a coolant system is to allow for a higher fluid temperature without boiling. The secondary benefit would be to prevent evaporation of the fluid, requiring that fluid to be replenished over time. Since the supercharger coolant never sees temperatures high enough to boil, the system never needs to be pressurized. A sealed system would be advantageous for level maintenance but even in a sealed system it would not inherently pressurize.

When I went on a dyno the water was shooting from the reservoir pressure release hole.. Any idea?? I am going to put the engine bay tank, the little one isn't as great

What? No.

Ok
Let me rephrase controlling the pressure.
I know what I measured and what is working in my car and you have yours.
Its not about debating I have my results and you have yours.
It's all good.

it is Pierburg CWA 50 pump with BMW reservoir and a 10 lbs pressure relief screw in valve on top. level on water is down about 1.5 inches. its also run in a circuit not as a fill point. pump is ran with 12 volts ignition. i found with this setup my heat exchanger gets even temps with no cavities of air. pressure relief is so back pressure does not restrict pump from flowing. if you look at the CM30's i think they stop flowing at a low pressure rate. the system is already tough to flow through with all the restrictions. i just took a temp gauge and measured water temps before pump install and after, then with pump running all the time and then with the relief valve in. the valve helps after a hard run where water gets hot and causes more pressure in system. to much pressure and a weak pump like the CM30 will stall and not flow at a good rate.
the cm30 will free flow close to the bosch pumps but its not the same when there are restrictions. The Pierburg CWA 50 will smoke both of them with restriction.

Thats why I keep my level down 1.5 inches
I have my breather hole plugged
With the pressure valve it allow some of that pressure to escape keeping PSI in range for pump to operate at specified flow rate

A 10psi breather valve cost only a buck too (search on eBay for grease pressure valve).

The Pierburg alone is the reason your temps are down. Also the reason you have pressure. So.. in your system Because you have the Pierburg / reservoir, you have to use a pressure valve.

That said. It is excellent information and nice to see you have that specific system worked out very well. Pictures would be great, and I'm curious where you vent that 10psi breather valve in to?

@95ONE please carefully read my post I did test my system with the CM30 and the Bosch. This is not a debate.
I just tried to open about what I found.
I now see why people choose not to post their findings.
It becomes a debate and people want you to prove what you found.
Im not selling anything just giving out info.

If you don't like kick back, questions, and challenges... then by all means, don't post.

im trying to post pictures now
Im also not saying this is the only way or the best way or even a good way it just worked for me
sorry for large picture
also your system is doing the same thing mine is you have a pressure cap on top to release pressure as well.
if you have it circulating why would you need to bleed the system? it should self bleed and air remain in reservoir
in my statement I said that "The key to cooling these S/C is pressurizing the cooling system. The key is to keep it equal to your pumps flow rate. There are many ways to do this."
post #8 there are many ways to do this
