How high a steady temp is safe to run?
Yesterday the temp topped 105F as is often does in the summer here. I took the cobra out for a cruise midafternoon and it rose gently to stop at 210F fully hot and running on the freeway after 20-25 minutes. In town traffic caused it to rise a bit further to about 215F. Oil pressure dropped from usual 38-40# running down to about 32# while running, 20# idling.
I've optimized the cooling system by every possible move short of shrouding the front to the radiator which I will soon be doing and in ambient temps under 95F it runs very nicely from 185-195F.
Summers are really hot here; I know some of you Texans and Arizonans have high temp outdoors experience...how high can I run a stable temp. without harming the engine? Should I be measuring oil temp too? Cylinder head temps?
Thanks for any replies!
Dirk
