Correct. The A/C lines run through the charger cooler. After the air is compressed(heated), it runs through the A/C cooled "charge cooler". .....
This would only apply IF the A/C compressor were turned on during a run. In the 80's when engines and horsepower got really small, A/C compressors were usually turned OFF while under heavy acceleration. Then they were turned back on during cruising speeds. I assume they are still doing this today. The Demon cools the "charge cooler" with the A/C system while you're at the starting line. When you launch, the A/C clutch uncouples for the length of the 1/4 mile. That's my guess.
My only question would be what they did to eliminate the water drip from the evaporator. Most tracks used to watch to make sure the AC drain was not dripping water in the starting box for obvious safety reasons.
In the early Buick days, we started with water-cooled IC's that circulated a dry ice cooled fluid across from a small tank to the core. This was a pain because one run warmed up the water and we had to drain the tank and start over.
Then we tried spraying CO2 on the core ala the ricers, but this is hard on a big expensive IC.
So it was an even bigger IC or methanol injection which acts as a fuel and chemical intercooler. Now, a lot of guys are switching to E85 (and a lot of it) instead of normal gasoline.
The hp chase never ends
I give a lot of credit to the engineers on the Hellcat and Demon programs. They have used a lot of science and engineering to make power that endures....
