Breathless Mods?

[TheGoodHummerMan]

I was wondering if reducing the engine cooling system's operating temperature by 14 to 20 degress would actually have any affect. Since the engines were designed to operate with the coolant at 192 degrees --- does dropping this temperature by 7 to 10% really help prolong engine life?

I remember back when it was common for carburated engines to have 160 degree thermostats and now these have been increased to 192 degrees. Maybe for a good reason?

The more I think about it, the more I think it might be a waste of time, effort and money to bother with these mods. Unless someone has something else to add?

Thanks, Ed
