Well just a quick thanks to you guys for all the help with the Efan install...though the Dccontroller has not arrived yet I did manage to get the thing wired up by a relay and toggle as we discussed. Now the good news is I kept the car running in the garage where the air temp was near 100 and humidity was 40%= blazin hot. The car warmed up to 205 in a matter of a few minutes and when I hit the switch the fan came on and in 2 minutes I was sitting at 182 degrees (hood down the whole time)....and the temp did not budge untill I shut the car down!!! So all I can say is the taurus fan is moving TONS of air, I didn't have the time to get her out but I have no concearns regarding wether temp will be an issue..it's more effective than the cluch fan IMO. I noticed the volts dropped from 13.5 at idle to 12.4-12.5 again at idle with the fan on..it takes some power but still excellent with the pullies in place I think. Thanks again and I'll let you know how the Dcc unit is once it's in place later this month.
