Frank,
I think that your trouble probably is originating from an alternator getting ready for recycling. The engine heat that transmits to the cockpit is minimal in SPF's and even if it was substantial, it wouldn't effect your gauges or turn signals. I'd also check the ground connections to see if you're short circuiting. What is your SPF number?
The group to really answer your questions is over on SCOF where nearly every imaginable question has been addressed by Superformance owners.
