Thanks I appreciate the input so far. After some input I'll try -2 bottles of water wetter -wire the fan (THE COOLANT FILLED ONE ) to run "always" as soon as the car is started vs's only upon stat demand @ 195 degrees as the factory has it set up. -lastly I'll change the stat (just to make sure it's perfectly operating) this will be step 1 ..... I have a couple ideas I'll try if there is no improvement. | ||

The Ferrari guys (being clever Italian engineers) designed the Thermostat so that if it is removed, the engine will not cool. Instead of opening with temperature, It closes! So that to remove it, you have to make a fitting that closes off the venting tube. Challenge cars are notoriously hard to get up to operating temperatures (just what you want in a race car by the way) but not what you want in a passeneger car. What I would do instead, it to make a switch that can run the fans (both sides) under driver control, so that you can switch these fans on when you are 5 minutes away from destination and have the car cool when you arrive. Also, you can use less coolant (25% glycol, 75% water, and some water wetter) for more heat transfer capability. Or, you could consider living in a less hot area (like Texas--saves at leat 10 degrees)...... | ||

There is no plate to restrict the flow, just the bypass circuit closed with a plug. The spec is in the 355 Challenge manual, which I don't own. This is not recommended for a road car. It will affect emisions, and take longer to warm up the engine in cold weather. Bill, you shouldn't have to do this modification, even for Arizona. Search for this topic as we discussed reducing the amount of anti-freeze to increase heat transfer / capacity of the cooling system. Don't remove the thermostat. Rob | ||

It is my understanding that in the challenge cars there is a flat plate w/ a hole in it that is used to replace the t-stat.Does anyone know where to get one?? Or what are the specs on the plate itself (the hole size) It's either that or I'll have to concider removing the stat all together and see if I can get this car to run cooler than it is now. No it's never overheated BUT it has gotten close and I'd like to be able to not have to park my 355 in Arizona during the summer,I daily drive it and love it although @ 110-115 degrees you definatly need to do some creative cooling. Any input is appreciated. |
