Simplified coolant system (for track use)
I am planning to re-do the stock cooling system for simplicity, weight savings, and hopefully a little better cooling.
It looks like I need these two things (or the equivalent):
Fill / pressure tank to replace the black one in the passenger side by the firewall
http://www.hrpworld.com/index.cfm?fo...action=product
or this one
http://www.cantonracingproducts.com/...ion&key=80-200
Plus - Overflow / catch can to replace the plastic one in the nose of the car
http://www.cantonracingproducts.com/...ion&key=80-250
I plan to mount both the the firewall where the heater core was. I assume the catch can needs to be lower than the filler tank - or does the pressure in the system make this irrelevant?
Am I missing anything?

The catch can is pressure driven by the cap so it should be OK the only issue I see is coolant in the line will never drip out of it if it is higher. That is if the the new tank is 2 way activated like the stock one is. I see only 1 fitting and a drain valve on the catch can but I imagine you could put a fitting in place of the drain.Looking at the tanks I do not see a return fitting only an overflow.So how is it going to pull coolant back when the engine cools?

If you look at the stock surge tank you see 2 hoses near the cap. One is overflow the other is a return from the oveflow tank. When the engine heats up the cap allows the expansion overflow to go into the tank(upper hose). When it cools the lower hose pulls fluid back into the surge tank from the tank.I believe it has a one way valve in the line. That is why the dipstick in the tank has a full hot and full cold mark.One hose goes to the top of the tank and the other to the bottom.
