      Swirl pot for superchager heat exchanger

      I really like a cleaner looking engine bay and a big coolant reservoir kinda makes that tough plus Im running out of room. I was kinda thinking about running something like this right before the intercooler pump in front of the core support to allow air to bleed out as well as create a fill point. Anyone done anything like that before?

      Would that decrease the overall capacity of the system? I would think that more water is better.

      No it would add a little bit of capacity over my current setup. My filler is basically on the supercharger lid and if I dont tilt it flat after filling the system it hits the hood.

      Adding the swirl pot certainly won't hurt at all, but I am not convinced the primary benefit (air bleeding/aeration reduction) is worth much of anything for a supercharger system. I would put the effort into finding a better spot to mount the largest reservoir I reasonably could.

      Show me the rest of your engine bay. The more coolant the better for cooling and to help lower iat
      I made this and had someone weld it up. Lots of places online that can make sure a tank

      Here it is. What you cant really see is the crankcase vent, power steering resi and radiator over flow. Basically every square inch if my core support is being used.

      Move the catch can to the engine. Plenty of lsa mounts for them or make your own like I did. Move that fuse panel over some. Put a nice tank there like I did. Either that or check out snowblind camaro and put a tank above the fender. Any extra volume will help.

      So what does adding a larger intercooler reservoir do? What's the advantage of having a very large reservoir vs. having one that is just large enough to deal with filling/de-airing/expansion/etc. ?

      I’m kind of with Carl on this one. Once it reaches steady state temperature there is no benefit that I can see. It helps if you are drag racing and starting out cold but for constant driving I’m not understanding the gain. For drag racing you would use an ice packed reservoir.

      In fact it will take longer to cool off, won’t it?

      I think it would help because more cooler water is available, so the cycle time is reduced. I'm just spitballing here...need an engineer...lol

      Can you move your Infinity Box power cell? Like make a mounting plate and turn it 90* and mount it to the fender.

      Heat = mass * delta T * specific heat

      So if you increase the mass (volume) of the coolant by 20% then it absorbs 20% more heat before it reaches steady state temperature.

      Just not seeing why folks are so convinced that adding a little volume will improve cooling. It only slows the rise to steady state temperature as determined by the heat exchangers. It will also slow the cooling when the heat is reduced....

      More volume of water will help increase the ability for the water to cool down. Think of a drop of water going thru the cycle. If you had just enough water it would constantly cycle and not spend enough time in a cooler area aka the tank. It takes longer for that droplet to continue its cycle again thus helping it stay cooler. That dame droplet doesn’t see the heat area as often which would help it stay at a lower temp and when it goes into the heat exchanger it will be easier to cool. More body of water the longer it will take to heat up the body of water

      You are only prolonging the time it takes to reach steady state. Once steady state is reached no amount of coolant makes any difference. How much are you increasing the system volume by in percent? That is how much longer it takes to reach steady state. Steady state is determined by the heat exchangers, not the volume of coolant.

      The only benefit would be is short bursts like drag racing.

      If what you are saying is true then you could cure an overheating radiator by adding an additional reservoir but you never see that done because it doesn’t work....

      Take a look at Mark Stielows cars. He manages heat by using larger more efficient heat exchangers, not by adding coolant reservoirs.

      I used the same reservoir that the CTS-V used for my build. The reservoir is similar to the swirl pot concept. When the pump is running I can see the fluid churning in the reservoir and the reservoir cap is like a radiator cap in that it allows fluid to escape if the pressure gets too high.
