So, with the huge empty space above the radiator, and the big power numbers these have proved to gain in the past, we decided to make a custom coolant tank... because.. well, why not?
We made a custom tank for the CTS-V that we run a 50/50 mix of anti-freeze and water, or if you are at the track and need some extra power, throw some ice in there. We have a in ground dyno jet here at the shop, and did a back to back dyno run with just the coolant, then added ice, and saw a gain of 60whp! So if you are trying to shave some time off your quarter mile, this is an easy way to do it. Tank reservoir will be aprox 1.75 gallons. Check out the pics and let me know what you guys think.
