Horsepower = Heat?

[RICK LAKE]

DocDirk Doc Has this problem been going one since day 1? Is the motor new or does it have 2-3 thousand miles on it? What is the thermostat opening #. Do you see a 20-30 degree drop in the temp gauge when the thermostat opens? 50/50 coolant in the cars coolant system? That is a big motor in a small space. 225 is not that crazy of a number on hot days. Try this, do a heavy taping of your hood latches to hold open the back of the hood and give the hot air a place to go, Go for your normal road run and see how hot the motor gets with this opening. If the temps are alot lower than there is no problem with the motor. You need to fine a way to help remove the hot air under the hood. Heat wrap on the headers is a good start. Get yourself a infrared gun for temp readings and check the radiator from top to bottom on both sides and see what the readings are. I have added 2 4" bildge fans to help remove hot air when racing. This has helped to lower temps. Is your radiator straight up and down or at a 30 degree angle? If it is at an angle you may want to add a splitter in the opening to help the air get directed through the whole radiator. ERA sells the with their cars. Rick L. Ps Doc I looked to your pulleys and the water pump is smaller than the crank. This is a undersize setup. The coolant flow for your motor may not be enough. I ran a set of March pulleys on my FE an the water pump was spinning too slow. This was with a high flow pump. Crank pulley and water pump need to be 1-1. Are they March? I was told the same thing from March about the problem of overheating was EVERYTHING but their pulleys. I changed radiators, thermostats to a Dodge larger one, only the connection to the waterpump and radiator are rubber, to stop and collaspe on the lines, removed the intake and cleaned out the ports on the manifold of flashing where the coolant flows. I ended up going with stock size upper and lower pulleys from ASP to stop the heating issues. Both pulleys are about 6" ASP builds custom pulleys and ships them in 24 hours. I have had no issue with over heating for the last 5 years. A also went from a 452, 9.2 compression motor to a 482 with 10.5 and over 100+ added HP and torque. Rick
