I want to hit 45 in a highway cruise, flatland. Since I have a creaky wheelbearing causing some drag, etc, I figure it's setting the bar low. Unfortunately 70% of my driving is short distance, in town, mountainous... I'd be very happy to get 30-32 in town.
Daox, disagree. A stock B7 cam is a loss of power over all operating ranges. Also, whether I am getting more or less airflow at a part throttle cruise and at a given rpm due to a cam change is also irrelevant as I am not travelling at WOT. Since horsepower can be expressed as airflow, I merely tailor my throttle angle to the power (airflow) level needed to maintain a highway cruise. Tuning AFRs and timing in the cruise region, especially if the car wants to cruise at a lesser vacuum where the ECU attempts to lodge itself in open loop, is critical... if I was not able to tune the setup, though, you are correct a cam swap would net a pretty big FE loss.
