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 |

ALL air entering the trunk through your front openings should be ducted to the radiator. If the air has any way to get around the core, it will go that way rather than do any cooling (path of least resistance and all...). On the RH setup the top plate from the front wall to the top of the radiator is critical. If your set up is open, that was my impression after your last post, the fans are the only thing forcing air through the core, leading to cooling with the fans on and much less while they're off.
