well the weather man says over 100 again here tomorrow and no air. heat index gonna be close to 110.
dont know about springers , but 02 has its limits in the heat as well, not only direct sunlight but just plain hot temps. might lower the output of the 02. Now springers, I dont think it will hurt them, unless its really hot. they generate enough heat as it is , and any more could be bad for the seals, lubes. not sure , but I remember reading about that once before. could be wrong tho.
