I have a few questions for those who really know:
1. How much does the angle of an intake really affect performance?
2. How much does the shape of an intake affect performance? [Eg. A stock Maxi exhaust header (commonly used as an intake) is more oblong than round. Does this affect performance in any real way?]
3. How much would a small dent in an intake affect performance? My thought would be that a dent would cause a small amount of unwanted turbulence, thus leading to a loss of power. True?
