To all who have installed an intercooler reservoir/ice box in the trunk, I'm looking for your feedback. I'm mainly interested in the twin screw setups.
1. What is the capacity of your tank (in gals of water and lbs of ice)?
2. How many passes do you get at the track before the ice melts?
3. How do you have your hoses run (e.g., from tank-to-heat echanger-to-manifold, or from tank-to-manifold-to-heat exchanger)?
4. Where did you physically mount the I/C pump? And at what point in the hose routing loop is it located?
5. What brand or custom made tank did you get?
6. Finally, feel free to post any pics you might have.
TIA...

1. 7 gallons. Not sure how much ice
2. 2 passes
3. Hoses run from tank to manifold to H/E, then back to tank. When driving to work I have not noticed any difference in IATs.
4. Below the tank. The pump needs to be set up to PUSH water up to the manifold. By being below the tank, I am ensuring the pump will always have water to push. When I first hooked this up, I had trouble with air in the system. But after releasing the pressure a couple times after driving, there is no longer any air in the system. Just to make sure, however, I turn the key over without starting the car, to hear the water flow back into the tank, then start the car. I have since checked several times, and have not encountered the pressurized air in the system like the first couple days.
5. ST---version 2
6. See below with comments:
Notice the drain handle I mounted upside down, so I can open and close it properly. Also, the drain hose you can run out an existing hole in the trunk covered by a large groumet. Same can be done with the incoming hose from the H/E. There is a large existing groumet on each side towards the front of the trunk, by the back seat.
The pump itself. So far I just used the same bracket that was used to mount the pump up front in the whipple kit. I plan on making my own bracket so I can raise it up a couple inches but still be below the tank. Notice the wiring for the pump, if you route it to the rear, you can come in the trunk using another existing groumet.
The hoses I ran using the frame rail, and keeping the hoses as far away as possible from any exhaust piping. I had the line that goes to the manifold from the tank-come in from the big hole that is below where the stock battery sits. The line from the H/E I ran below and met up with the incoming line at the frame rail, then ran them both together to the rear of the car.
The tank itself, 7 gallons
Close up of the drain, mounted upside down so you can open/close it properly.
