What do I do about cooling?

Tomorrow I am dropping off my ZL1 to get the following work done: intake and headers. I live in Vegas where the temps are Always around 110 in the summer. Therefore, I am concerned about cooling. Should I do an upgraded heat exchanger? I'm not gonna be on the boost all the time like a fast and the furious racer. I just want reliable mods, and a reliable car. Please let me know what you guys think I should do.

I live in Houston. I had similar work done on my ZL1. The resulting IAT2 temps after two pulls on the dyno exceeded 200 degrees using the stock heat exchanger system. As a result, the car pulls a lot of timing and you lose a lot of power. If you want reliable (continuous) horsepower, you will need to upgrade the heat exchanger. (In my opinion, that includes a h/e with fans and and an upgraded pump if you drive in traffic)

Here's your answer and it doesn't get any better than this.

We offer a few cooling packages for these but with those mods:

1. Torq Dual Pass Heat Exchanger
2. Torq Intercooler Pump Upgrade

Some of the biggest shops in the country are using our components on the fastest ZL's in the country

Excellent mods if you dont want to cool below ambient air temps.

Great point; howeber, have you tried running even a STOCK ZL1 with the AC on during a road course or Auto-X and monitored ECT's and then tried it with the AC off?

What about endurance laps around a road course with multilpe WOT blasts when the condenser shuts off?

I believe they did some testing on the road course on a GTO or G8 under these conditions, but haven't had a chance to review their thread.

I could see a great improvement in IATs from either of these choices for different reasons

Would love to see the IAT2 and ECT data for this car, not a G8.

Our stock ZL1 overheats with AC running.

Would the super chiller require a tune for the ZL1 to adjust for the drastically lower IAT2 temps?

Now, the cooler IAT's will result in spark and fueling changes from the factory PCM. To really take advantage of this a tune would be great.
