I could never find MSD's control box's operating temperture range but the Autronic's 500R CID is stated at -25 C to 85 C and I know that my engine bay on the exhaust maifold side at the fender can grt to 180 F on a 80 F degree day, on the day's in the mid 90's it climbs over 200.

I think in Detroit what saved the MSD box was I was getting a flow of air in the engine compartment while I was on the track (High speeds) but when I was back home driving on the street it just got too hot and fried.

I built a cool tunnel with the help of Tifso and Green Dragon's input that has a ram air intake and a secondary inlet that has a fan to pump in outside air in when the car is at a stand still.

So far it has shown a 60 F to 70 F difference (lower temp) inside the cool tunnel then outside on the hwy use and 50 F to 60 F difference in city driving.

This should keep me in the operating temperture range of the ignition control box.

As a side note I think the direct fire igniton box's run hotter than the waste spark box's?
