You would be the first person I have heard of that would remove the GFD system. That thing moves a LOT of air, even when freespinning... When is the last time you broke a 12k halfshaft?

LOL. Did you just tell us again that your fan will always be running on high? Operating temp of my engine is not below 180. You also mentioned an operating temp of 200-210. So, the fan will always be on , on high speed..... If the operating temp is 20-30 degrees hotter than the fan OFF temp...

Im still hung up on the temps. You say my truck will stay 200-210. Your fan comes on low at 180 and high at 200. Doesn’t that mean your fan will be running on high ALWAYS, once the engine warms up? And, if im not mistaken, the hydraulic fan turns on at 220 and shuts off about 200. And only...

Over 300,000 trucks pushed out the door, and AMG didn’t feel it was needed.

So, I can spend $200 and use what some guys in the military did. Or spend $1,000 for the setup listed here. Both claim more horsepower.

When did the military use electric fans on the cooling stack? The H1 community has tried this for a long time and many agree that electric fans on these trucks block more air than they move. For a good comparison, what is the cfm rating of our hydraulic fan?
