Temperature Limits: Motor is equipped with thermal protection. For user safety, optimal performance, and maximum motor life, the motor surface temperature should not exceed 150°F (66°C).(See Heat Rise graph)

I guess you know something I don't, or I should say the folks at Devil's Own?

I can drive around a bunch, even on the hottest S.C. days, and I can grap the intake manifold with my bare hand and it's not "hot" or even something where I would feel I needed to pull my hand back in a hurry. Since it's seperated by rubber feet, I have a hard time believing that the ambient air by the intake ever gets above 150F even on the worst of S.C. heat ...

I will contact Devil's Own on Monday and ask them about your concerns. I am guessing they know perhaps better?
