Superformance Cobras have really excellent radiators (heat exchangers) so excessive water temp is seldom a problem , even in high ambient conditions. The trick is keeping the
oil temp high enough to give maximum efficiency but still controlled enough so that
oil temps don't exceed 300F.The important thing to remember is keeping the
oil above 212F so that any accumulated moisture is boiled off reducing the chance of acidity and water lurking in the engine oil. Superformance oil/water heat exchangers are sometimes too cool for the street and not capable enough to handle track work. A seperate oil cooler may be needed for track work. The best are thermo-controlled units so the oil temp isn't too cool on the street. Badger
