Easter,
What happens to the vehicle in your example when the pressure in the radiator and the tank equalize? Where will the pressure go then? It will eventually vent. The end result is the same as the L.

properly filled the L will vent hot air for a long time before any liquid comes out - Not sure what the expansion rate/capacity of heated or super heated water/coolant is but there is LOTs of headroom in my tank...

Mines just a straight up coolant tank just like the stock one does except it holds 7 gallons now in the entire system when full.
My system does get pressure built up in it when you run the truck but I only run about 3/4 of the system on the street full. At the track I can make 3 or 4 passes with the cooler packed with ice and never have a problem though, it works perfect!

I agree with Doug...it seems there is plenty of room in there so that coolant would never be able to reach the top and escape, even under the most extreme conditions.

If your venting antifreeze then you have some kind of problem, I would guess you have a bad head gasket. If everything is working right you shouldn't be venting any fluid. As far as the rules our system meets nhra specs.

The overflow tank is not pressurized. It is what it is an overflow tank. The expansion tank on the Lightning is pressurized.

Okay. I have an aftermarket Moroso expansion tank. It has 4 openings.
1. connects to lower radiator hose like stock expansion tank.
2. connects to top 1/4th inch radiator hose.
3. cap(not a screw cap, but a standard radiator cap)
4. nipple to overflow
When/if the pressure in the system reaches 16psi the bottom of the cap raises and vents the pressure/water to an overflow bottle which must be 1 pint in size.
If the stock system reaches 16psi the cap will vent pressure/water to the engine compartment.
So, do I need the overflow bottle with the moroso expansion tank? If I do the stock system also needs one. If I don't then why does the moroso expansion tank have a nipple which attaches to an overflow tank?

If the stock tank and the moroso tank are not the same size and design then you cant make the assumption that if one needs an additional tank the other does as well.
Similar analogy. If you run stock tires you dont need a drive shaft loop. if you change the tires to slicks you need one. Since you changed the stock reservoir you may have to abide by additional rules that DONT apply to stock.

The size is the only basic difference. Everything else is essentially the same.
