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 '70 914/350/4 webers |

Tyler:
The first question I have is how much HP are making? In my case I have 383 pumping out about 500HP. I bought a cheap alu radiator for a camaro (31" X 19") from Summit. Then I made sure that the air intake was 40% of the radiator area, enclosed the radiator in sheet alu to DUCT the airflow and exhausted out the BOTTOM of the trunk, NOT the fenderwells. I drove it yesterday in 85 degree temps and after getting to 40MPH, I shut off the cooling fans and it ran happily at 180 degrees! The car runs 200 on the track at Willow Springs. I am running a restrictor washer instead of a T-stat, but will stick in a 180 degree unit some time. Why, because on COLD mornings (50degrees F) the water temp will stay DOWN at 140 degrees! I have a RennSpeed nose and Spoilers to the ground to KEEP airflow from going under the car. I hope this is a help, Terry |
