I went around today in a T-shirt, as it was mostly sunny this afternoon.. I miss the sun. (Seems weird coming from me, if you know me, I normally stay out of the sun.)
As far as heat, I suggested to BenNelson that he could vent the heat from the motor through the cabin air filter.. (maybe replace it with a higher-flowing element...)
You've got 200-CFM on two fans... you're pushing more air than the stock blower, and maybe, just maybe, you'd be able to heat the car with the OEM setup.
Another idea would be a water - air heat exchanger (radiator) mounted at the exit of the airflow on your (apparently super hot) motor, and running a coolant mixture back to your heater core through it. Of course, for this, you're losing a little range, since you've got to run a blower, the fans, AND a water pump.
You could plumb the hot air back to your cabin air filter, AND run a radiator piped to your heat core... this negates the blower motor, and you're already running the cooling fans, so you're just adding a small water pump. This method probably has the least impact on "mileage", will provide the most heat, (probably more than you need), and is pretty easy to map out in my head... seems VERY pheasible, and with pics, I could MSPaint something to show you exactly what I mean.
And yes, I'd do that for you, just b/c you don't have the heat-retaining capabilities of someone like Oprah... (damn, that's alot of insulation.)
Oh, and I like you.
