WOW!
I should have done this years ago!
Taking the mechanical fan off really livened up the power out of the 4L, 5th gear has power and use for other than cruising!
Though I have to relearn how the motor sounds without the roar of the fan, she is quiet, and powerful!
Not to mention fuel efficient! I went from 300-330 km on a tank of gas (city or highway, didn't matter); and got 400 on the highway!! I made Revelstoke from my place in Beddington with 10L to spare! Before, I would have to fillup in Golden.
Highly recommended for ALL 4L users!
