Depending on what engine you have, the Dodge Dynasty had one or two electric fans on the back of the radiator. These fans are turned on by the computer when the sensor indectate that things are too hot. This can be anything over 190 degrees, depending on your thermostat.

So naturally, one could cool the car down more if the fans can be made to be controled manually. With the flick of a switch, they could be made to stay on.

This helps keep the engine cool, which can be quite helpful whenever things are getting hot, or when you know the extra coolness will be helpful (like at the track...).

There are kits/parts out there for under $30 which can be used to manually control the fan(s), or to control what temperature turns them on. This is alright, but a similar setup can be made with a $1 electrical switch, and under $1 in wire. Talk about cheap!

Basically the fan turns on when 12 volts DC (+) hits the fan's motor and the motor always has a ground, or vise versa. When the computer wants to turn on a fan, it basically just sends 12 volts to it (or a ground, depending on the design). So to manually turn on a fan, just have a switch which would turn on 12 volts to the fan's +12 volt input (or give it a ground if the fan uses that to turn it on/off).

One suggested way to do this is to run a wire from the battery's + terminal to a switch on the dash, to the positive end of the fan's motor. Flicking the switch turns on the fan.

Now if you want to do a little better then that, you can run the 12 volts through the ignition switch, so that the fan can't be left on when the car is off. An other idea may be to add an led on the dash which will turn on when the switch is in the on position, so you can't forget the fan is on.

The 3.3's radiators use two fans- a primary and secondary fan, both of which can be controled seperately from each other by the PCM. In this case, you can have one switch control both (by running a wire to both positive sides of the fan from a +12 volt source), or you could use two seperate switches (and then could then control either fan seperately).

JC Whitney sells switches for $2.99 which have lights in them, so that the switch lights up when the fan is turned on. This feature would elminate the need for an led.

While on the topic of fans, in some cases, it is possible to fit the dual fan system from a 3.3 in other Mopar engine-driven models. The Dynasty shouldn't be an exception for that. Cooling is mucho importanto. Removing the AC system helps (as that also dumps that AC radiator in front of the engine coolant radiator- which means less weight, and more airflow to the main radiator), but other ideas include making air dams/ducts/scopes under the car to bring cooler air up into the car, then remove the weather strip seal ontop of the firewall. Hot air leaves through that, cool air is pushed up into the bottom of the bay. It may be possible to get some good cooling fans for each of these new cool air paths to aid in collecting air. Just a thought which one can go farther into.
