that is extremely helpful info azjulian. i am running with a 15 lb cap. it has been suggested by jclayton that i go to a 30 lb cap. i am feeling much better about the heat. took bad asp out tonight and for the first time took it on the highway. temp stayed at 90c. drove it in 45h,5th and 6th and the temp remained constant. thank you all for the invaluable info. success with these things really does come down to a team effort doesn't it. right now i'm about 30% antifreeze and 70% water with a full bottle of water wetter.
