If the vane has to be oriented with respect to gravity, then does that mean that I have a problem?The vane meter approach has some drawbacks:
* it restricts airflow which limits engine output
* its moving electrical or mechanical contacts can wear
* finding a suitable mounting location within a confined engine compartment is problematic
* the vane has to be oriented with respect to gravity.
Obviously with this cold-air setup, the VAF is *not* oriented with respect to gravity. Should I re-orient it?
Also what happens if the driver drives up a hill?
