When the dyno shop did the break-in run and dyno pulls, the engine was plumbed with an electric water pump and a controlled/cooled water supply. After they were done on the dyno they changed the oil, bolted on my new Edelbrock waterpump, and plumbed in a heavy duty racing radiator with a large electric fan. We then ran it for 20 minutes checking for leaks and it never went over 180*F. When I got it home and bolted it into the go-kart, I then put 20+ miles on it running around the subdivision before mounting the body and it never got above 180*F. Then I mounted the body and it started idling hot. No way its the engine.
EDIT>> Every engine will run hot and eventually melt down if its not cooled. By laying a second pusher fan in the nose I can hold the temps to 195, and that's still leaving two full corners of the radiator without direct airflow. So I am not sure at that point I am any different than any other properly cooled Cobra: Cooling system is discharging engine heat and keeping the engine cool enough to operate at idle and roadspeed.
