I recently purchased and installed the C7 Cordes Performance Trunk mounted ice tank, I have been running standing mile events and have recently added a 2.9 Whipple Supercharger with more boost. Most everyone knows how important it is to control intake manifold temps to prevent timing from being retarded which in turn reduces horsepower.
First off I will say that Joe answered the phone, I told him my concern and that I had a tight time frame, he immediately handled it and the tank was delivered to me 2 days later. I had to call back with a couple questions, I was told they would give Joe the message and he would call back, he did just a couple hours later. Thats service folks, and something that is badly lacking with some other performance shops I have dealt with lately. And By The Way, I have exchanged emails with them a couple of times, same day or next day response every time, so thanks CPR I appreciate the way you do business!
The tank quality is excellent, the hoses they sent are very high quality, after speaking with Joe and the setup I have with the Whipple we decided to run the outlet from the tank down the drivers side and the return from the blower down the passenger side, so we used a 90 degree for drivers side and a 45 degree for passenger side.
I will be adding to this thread with results and updates as I go.


Passenger side coming from trunk area.

Drivers side coming from trunk area.

Passenger side, I later actually ran this into the hole and came out the very back where the wiring harness you see is, that got the hose tucked up close to the side of the trunk area and made it much neater to trim the interior panel.



Drivers side, be careful to keep hose away from the gas cap door locking mechanism, I tie wrapped it away from it because if it touches that mechanism it could cause it to hang up and prevent your gas door from unlocking.





Hole drilled for drain hose.

Relay mounted and wired for 3700 rule pump. I ran the trigger wire down the passenger side with the hose to the under hood fuse panel and just used a micro add a fuse and hooked it into the factory intercooler pump fuse. I wanted to be able to put the car in service mode (hold down start button without touching the brake (or clutch pedal) for a few seconds and the dash will light up and the intercooler pump and now the Rule 3700 will also come on, I preferred to wire it this way because its just something I do not want to have to remember to turn on every time I start the car. The Rule pump is actually not loud at all and I cant even hear at all after the car is running even with the dual mode exhaust valves closed, but my car is louder than most, headers, no cats.

Hose for drain.



I drilled this hole for the drivers side hose so it would be easier to reinstall the interior panel and also to get the hose routed closely to the side of the trunk area. I wrapped the hose with black racers tape to provide a little extra abrasion protection because it runs close to the retainer for the interior panel.

I wrapped the hoses here with just regular water pipe insulation for a little extra insulation and to cover the connections and adapters between the 1 inch hose and the factory hoses. This pipe wrap is rated to 210 degrees, I have driven the car around fully warmed up in 90 degree ambient temps with no issues, I also tested it with my heat gun up to 500 degrees and it just kind of melts and deforms and I see no possibility of it catching on fire from excessive heat. I would also like to add that the way I have ran the hoses in conjunction with the factory intercooler pump. I simply unhooked the feed line (lower connection on Supercharger) that comes from the intercooler pump and adapted it from 5/8 hose to 1 inch hose that you see going to the passenger side. The feed that is coming from the trunk tank is going straight into the blower and then the other line coming from the blower (that has the bleed cap for getting air out of the stock system) continues on through the stock intercooler over to the stock intercooler tank on the passenger side and then back through the stock intercooler again down to the stock intercooler pump and then on back down the passenger side back to the rear mounted tank and then starts over again.
If I decide to take the car on a long trip or I will not be needing the ice tank in the rear, all I have to do is unhook 1 adapted connection, hook the stock intercooler hose right back into the supercharger bleed it and unplug the 2 wire electrical connector I installed at the rear tank. 15-20 minutes roughly.
I also tested the system with the rule unhooked to see if the stock intercooler pump could run this entire system without the rule for regular driving and no it is not efficient enough to handle all of the additional hoses and rear tank.
As far as needing to bleed the intercooler system with the rule running inline with the stock pump it is not necessary! I hooked my bleeder hose to the stock cap you use to get the air out of the stock system when I engaged the pumps, coolant went rushing out of the bleeder at a very quick rate!
I just don’t feel like there is anyway for air to be trapped in the system with the rule pump pushing the volumes of water it does.




I attached the drain to one of the bolts at the rear exhaust.

The trunk lid closes with no issues, I could attach this hose to the rear panel for a neater installation but I didn’t want to drill into this panel.



The net still works just like Joe said it would.

Here is a little test video I did to show how much water the rule can flow prior to installing it!

More updates to come!

This video shows the Rule 3700 pump is not loud at all, I never here it after the car is started.

 

I just wanted to update this with actual real world results.
I ran 200MPH in the mile on 9-29-2019 in Blytheville Arkansas with the ECTA.
This rear mounted Ice tank played a major role in getting it done. We were dealing with 90 degree temps all 3 days and a 10-15 mph headwind so we needed every bit of horsepower we could squeeze out of it.

I warmed the car up early in the morning and got the oil temperature up to around 150 degrees by driving up and down the side runway. I would then shut the car off and we would put 3 fans on the engine, drain the tank in the rear and then fill it with ice, ( we added 4-5 bags of ice during this process) we had an extra battery with the same plug that I had in the car so we could plug the pump up without turning the ignition on in the car. With the rule pump circulating the cold water through the blower and with the fans cooling the engine and blower off even more, within about 30 minutes or less the blower was COLD, the lid and everything was cold. We then drained all the water from the tank and packed the tank with ice. After that we would pull the car to the starting line, we were 1 mile from the starting line.
On a couple of our previous runs where we ran 197 twice and 199 we would start the car when they told us we were next but most of the time that would be 3-5 minutes of idling—that’s too long. So on the 200 MPH run we pulled the car right up to the starting line, we told the starter when it is our turn we will start the car then.
The data log on that run showed MAT temp at 85 degrees when the car was started and at the end of the mile the MAT was 100 degrees! Even after driving the car all the way back to the pits the MAT was still only 120 degrees.
So this tank works as advertised and it is a truly well designed piece, if you are drag racing or doing 1/2 or 1 mile events i highly recommend it to help reach your goals!
Thank you Cordes Performance!

 

That is pretty awesome, I like how it fits into the cubby.

I have zero need for that but I was just thinking if there was a cooler for a COOL SHIRT system that fit into that cubby that would be super swell.

Regardless pretty cool setup!

 

Thank you! I bet you could fab something up to do that, that cubby hole is pretty deep.

 

Thanks for the really good information. Do you think it would make a noticeable difference in car driving on a road course? I have a C7 Z with an EForce supercharger (2300), cam, head work, long tubes, A8 radiator, GSpeed cheek coolers and underhood tank. I live in NE Oklahoma and several times a year I take my car to Hallett for high performance driving events. It's a 15 minute session on the road course. After a couple of laps I start loosing some power due to my IAT's going up and my tune pulling timing. I've tried just about everything to extend my drive time but just recently heard about this ice tank. With that much capacity, I'm thinking it would keep IAT's down to a manageable level. What do you think? Also I'm concerned about air getting into the system every time I drain the tank and add ice between driving sessions. Would I need to bleed it each time? Do you run straight water through your intercooler system or do you have some sort of lubricant / corrosion preventer? I do drive my car on the street a fair amount and on some trips. I should be able to run the ice tank year round as long as it has freeze protection, right?
Thanks for your time and help. I'm excited to to give this a try!!!

 

just responded to your pm.
