After years of my car sounding like a freekn harrier, and seeming almost adiabatic in its performance (literally could drive an hour at highway speeds, park, and safely place my hand on Air Intake Manifold ), I've decided to address the issue. It had never occurred to me that my lower than expected power across entire speed range could be due to the fan always being engaged, but being 500 miles past a complete engine rebuild with improved but still eh power, I have no other suspects in the system. So I have a couple of questions for this great forum.
#1: Is the clutch fan actually supposed to turn off completely at some point during operation of the vehicle?I know electronically controlled fans do. Mine doesn't , I don't remember if it ever did, and I haven't seen a definitive answer on this. The roar is my normal.
#2: Can a constantly engaged clutch fan significantly sap enough power such that traveling on a 5% grade requires gradually increased throttle just to maintain speed of 55 mph with WOT necessary after ≈1mile?
#3: Is there another , non-transmission related, non-vacuum related, non-misfire/ nofire related, plausible explanation for the behavior described in question 2?
