I have removed the clutch fan and have only the stock elec. fan. I want to upgrade to the largest most powerfull fan that will fit. Anybody done this yet?

All you need is the black magic 150. Anything else would be over kill and probably not fit.

Has anyone actually done a dyno run to see how much horsepower they have freed up with this mod?

I have.

On my Dodge Truck World site I actually have sort of a how to install that will show you the best way -- I think anyhow -- to get that BM150 installed.

All you need is the 150. Really. I was running my truck at Spokane a few weeks ago in 95 degrees.

True, I do have a couple other things. The most important thing to also change is the thermostat. Get a 180 in there and some new coolant and you're probably ready to go. My fan is on more when I walk away from my truck than when I am actually driving :)

In city driving and idling is about the only time is comes on.

I finally got it to above half on the temp. I had to be idling in 95+ heat with the A/C full blast and it'll do it. I shouldn't be idling like that anyhow, but damn was it hot for a Northern state (WA).
