  We turned to Harold Bettes, senior vice president of SuperFlow in Colorado Springs.Bettes has assembled a staff that regularly pursues the kind of information we intend to pass along.
  
  To set the stage for this series, we sat with Bettes for a conversation that laid the foundation for this and future discussions in our so-called "X-files of Racing" articles.
  ...
  As Bettes said, "At the track, the race team, car, and driver is the stack of the final compromises.We may have proven some things here in the lab, but it's impossible to manage that information for any team at a distance."
  
  How Do We Get There?First on the list for setting criteria of testing are proper procedures."Good testing procedures are very critical issue in the relationship of being able to prove or disprove changes or modifications or combinations of a given package.
  
  "It's very important to have good testing procedures in your data gathering so you will have faith that what you have is very reliable, and then there will be no fear in trying to apply new facts and ideas to a race program," said Bettes.
  
  When it comes to testing a new product or new theory, a very judicial part of the process is for the tester to resemble a blank piece of paper.That is, an examination of this nature has to be approached with no prejudiced ideas.Bettes puts it more succinctly: "If you are going to be a good tester, you cannot have any preconceived notions because you will prove those preconceptions, thereby you may be presenting ideas that are wrong or, at the very minimum, biased."
  
  Another major part of the testing criteria is retesting.This fundamental of testing is required because a single test will not provide the security of accu-racy.For instance, say some great numbers were found on a flow bench while testing a set of heads, only to learn that the plugs weren't installed.That would, of course, be bad data that appeared on a single test.So, other building blocks for any testing are test, repeat, repeat, and repeat.As Bettes said, "There is no substitute for testing, testing, testing."
  
  All of these criteria have become the foundational philosophy for this first venture into the X-files and will be employed in upcoming features.
  
  What Do We Test?We then moved to the chosen subject for investigation, engine oil-specifically, synthetic engine oil as it's compared in a race engine to mineral-based engine oil (also called petroleum-based).This became our first research in the X-files series.
  
  With the subject decided upon, Bettes turned us over to staff members Todd Poirson and Kevin Bailey to show us how our search would happen.

  It was in the early 1990s and SuperFlow's Harold Bettes, also a long-time and respected friend of mine, was calling to ask if I might coax Zora Arkus-Duntov to Colorado Springs for the event.

  But Harold wasn't giving up easily.In his next call, "Tell him he doesn't need to be a speaker.

  Absorption systems are the more flexible of the two, giving you more options than just acceleration testing, according to Harold Bettes, senior vice president of SuperFlow, a dynamometer manufacturer in Colorado Springs, CO.With an absorption dyno, example, you can easily control the load applied to the vehicle under test.
  
  Most chassis dynamometers include electronic instruments and control software.Another common feature is a handheld device that lets the operator control the dyno while in the driver's seat of the vehicle.
  
  Using a chassis dynamometer, you can test the performance of an entire vehicle.
  ...
  "It's the least invasive testing that can be done, and it's quick," Bettes says.It can also be expensive.According to Bettes, high-end chassis dynamometer systems bristling with instrumentation can cost as much as $400,000.At the other end of the spectrum are basic chassis dynos costing about $20,000.Accurate engine measurements are difficult to obtain, however, because of external factors, such as drivetrain losses and tire condition, that affect the readings.So, for applications that require accurate measurement of engine output, such as R&D and reliability and endurance testing, engine dynamometers are the best choice.
  
  Engine testing is easier and more accurate when you can test the engine by itself.Though designs vary, all engine dynamometers measure engine speed and torque, values that are used to calculate power.

  With this in mind, we sought the voice-or rather voices-of experience, namely our friend Steve Brulé of Westech Performance and our new friend, Harold Bettis of SuperFlow Technologies.
  ...
  Harold Bettis: An oval-port head leaves fewer opportunities for eddies and irregularities of flow in the corners, because there are no corners.
