Lots of good thoughts and thanks to all for taking the time to post them !!!!
The "Good News" I'm back to running the temp I was before the latest electric fan fiasco ! The "Bad News", I'm back to running the temps before the electric fan ! The problem is indeed, an air dam, blocking the ram air flow at all speeds. While the temp stayed "reasonable" (200*) even in traffic, with the A/C running, it never dropped below that either. At highway speeds, it was even worse (200-230) !!!
So I removed the fan and shroud to see if that was the problem or something else had changed ? I put the six blade flex fan and shoud back on. The temps dropped over 50 degrees on the highway and in general dropped 40 degrees around town in light traffic. Instead of running 200-210 degrees in general driving, she will cool down (170-180) as soon as I get moving down the road. The electric fan and shoud was blocking air not only at highway speeds, but also under city driving conditions.
So the question for today is: "
how to get the air flow of the electric fan at idle, without creating the air dam ?
The electric fan would hold temps at 200 while at idle, but if you were moving, it wouldn't allow the air flow to cool it down, even at low speeds. I can cool her down with the current set up, with one exception, "idle !" I don't have enough room for an electric fan addition in front of the mechanical.
May be the answer is an un-shrouded electric fan ? After this weekend's show-n-shines, I'll try that ? I still have a little money left, I think !!!!
There is a big show next weekend, that includes a parade down town. I've never been able to complete the cruise, and I'd sure like to
just once !!!!
