Getting 4.56s installed Saturday morning!
I went from the clutch fan to the Efan and have seen no change in temps. I do feel it rev up faster without the heavy clutch fan on the motor.Awesome, what gearing did you run the 12.5 on? 3.55? You're truck is wicked!
Is that the v6 electric fan? Did you notice cooling improvements switching to it? I ask because I run no mech fan and the stock efan with stock shroud and have not had any issues with 180 tstat and fan set to kick on at around 200 deg. While moving the coolant never gets above like 190-194, and when sitting it climbs, then the fan kicks on and it comes back down to around 194. Then I get moving again and the fan kicks off as the coolant cools down.
JW if it's only a space savings mod or if it moves more air...
