914/V8 Fan Operation, Conversion Cooling Options

[tyler]

Can you conversion guys tell me how your electric fans operate and if you've modified the air dam?
Put in my 15.5x28 Griffin radiator with 944 Turbo fans on a shroud. Crusin at 70 on the freeway the temp starts at 170 for 6 miles and creeps up to 195 when the fans come on and bring it back to 170. This continues to cycle like this both on the freeway and around town. I'm using a 160 Tsat until the cooling system is done. I ran with the lid off so I know the cuts in the wells are ok. So I figure I'm either blocking the airflow with the fans/shroud or the air dam need to channel the air in somehow. It doesn't seem to me like the temp should cycle like this. I'd like to hear how yours run.
Thanks,
Tyler

Tyler,

John is right. If you go with a 180 thermostat the temperature will stabilize better as it regulates at the higher temperature. If your temp sender is located in the head as opposed to the intake manifold next to the thermostat, you will also see more temp variations. I'm running a radiator sensor that fits between the fins and it has been working fine. Here lately with daytime temps around 105F, my engine temp goes up to 180 in a few minutes and once I'm on the highway for awhile it creeps up to 195. I have the fans kick on at a little lower temperature than really necessary, and let the thermostat do the regulation.
