Chiller recommendation.

Do they work? Which type is best? How much do they cost? Who should I call? What all is needed? How cold do I go? Anything I need to change on tune up? EFI car. Fast system. How much does it pick you up ET wise on a 85 degree day . Thanks

A professional type 110V chiller can cost upwards of 2 grand. Most guys in Stock/SS either dumb the water at the head of the lanes and refill with cold water, Or use a cooler with ice water in it and circulate the water through the cooler.

Steve offered a good over view. Are you looking for a cooler to use every round? One that you can use for a heads up run, a qualifier, etc? For E.T. improvement, I've seen a minimum of .004 to as much as .010...depends on the car.

Here's an article I wrote a few years back about engine chillers. All it takes is a good-sized ice chest, a swimming pool pump, rubber garden hose, Jiffy-Tite quick connect fittings and a C&R one-way coolant valve.

I built a chiller a few years ago that refrigerated the water like the 2K ones, it worked great, all the same parts and pieces as the cooler full of ice deal. The only problem, my 7K generator could not handle the LQ A/C, chiller, pumps and misc. The cooler, sump pump, and a lot of ice is the way to go. We used to take plastic coffee containers and freeze ice and store up for a race with the stocker motor.

Yea I like the one in the pic. I want it just for heads up runs.

You probably should still get some input from someone on the tune up as well. You don't want to run the car stone cold, but I know of at least one instance of "overcooling" that caused a fuel injected car to slow in a very critical race.

Was wandering the same. Has anyone had this backfire like a bog or slow down from being too cold?

Depending on what EFI system and what it is looking at to make tuning decisions, colder can definitely be a big problem. Any modifier that is adding fuel based on water or air temp could make it too rich or lean. Open vs closed loop and how much you allow it to add/remove fuel. As long as you are you willing to adjust the tuneup and these parameters it could make a difference.
