I have some thoughts about fan conversions...years ago before I heard of turbobricks I installed a Flex A Lite 2800 cfm fan from Jeg's, intended for 5.0 Mustangs, thinking that it would have more than enough umph. This was probably around 1996 or so...forget the brand of fan controller but it can handle at least 15 amps (I think), have a sensor in the radiator fins, and also a wire tapped into the a/c wire that runs to the low pressure switch on the receiver/drier. So fan comes on with a/c, also comes on with engine temp and has adjustable setting. Still works after all this time. It seems that my a/c has never been quite as strong and more likely to detonate under high boost on hot days - also temp creeps up on hot days at fast highway speeds, but not seriously. This is already an 18 amp fan. Actually considering switching back to a good (new) clutch and fan plus shroud. The (at least the factory intercooled 84.5 and 85) had an alternator downsized from 70 amps to 55, though I have the 70. Someone else mentioned the pusher fan in front of everything- according to the Volvo FSM's, this doesn't come on with the a/c- it's more of an emergency fan, and doesn't come on until the temp is approaching the red. I forget the temperature. Anyone know of testing done showing how much hp an engine (or even better, the 240 fan) driven fan can use? I have to wonder if it isn't that much...18 amp fan even if 100% efficient is 216 watts...sorry if this is off topic- not sure if whether to do the conversion belongs in a thread about how to do the conversion
