how many miles on the pump?
You said that the car "overheat" when you step on it.
What's the temperature?
Assuming that when you step on it,you are not doing that in neutral at a stop,that's pretty well remove the fan clutch from the equation.(when you move you have air flow)
Pump.most of the time when a pump go bad it is the bearing/seal that is the problem.
Pumps usually have what is called a "weeping hole" basicaly a 1/16 hole where you will see some coolant leak coming out from it if the seals/bearing are bad.
180 thermostat do nothing to change the temperature of the engine.
That's only mean that it is fully open at 180 and that the engine cannot run cooler than 180.
On a rare case the pump impeller can get loose, int his case there is no water circulation in the engine.
Since the viper don't have a regular radiator cap, the way to check it would be to start the car cold and with your hand on the upper radiator hose see if sudenly, when the thermostat open the hose become hot.
If it does you can assume that the problem is not with the pump.
That leave you with a stuck thermostat, incorect timing(don't know if is possible with the computer)or a cloged radiator.
Good luck.
