I got the fan lifted up the intake side, and cut a giant hole in the roof for the last 90* that goes up and out. The ducting has kicked my ass the entire way, but at least its getting close. I will estimate about 2 more days of decent work to get the motor mounted back on the fan (motor weighs about 120lb) and get the roof reinforced and sealed up. It wont be long now!! Hopefully this weekend we'll be able to test the fan and do some "play" dynos!!!
