Turbo; JH or PL?

  anybody that subscribes to Larry's beliefs will never win a race in a boost restricted racing class (...at least not by turning up the boost.  :)  Rules that prohibit the use of certain tools don't prove those tools are ineffective.  In fact, they rather indicate the opposite... ) since the they will have lost the only tuning tool they believe they have at their disposal. (Not the only tool, just the quickest/easiest/cheapest tool; increased boost.)
  As a matter of fact they'll never win a race in a racing class with unrestricted boost.
  Want proof?
  Just go here:
  http://www.turbobygarrett.com/turbobygarrett/tech_center/turbo_tech103.html
  and check out the formulas that reference volumetric efficiency (VE) i.e things that improve airflow into and out of the engine, like ports, manifolds, cams and exhaust systems. Yep, they're part of the equation.
  (I hope others reading that tech article (tech103) can find those references to ports, manifolds, cams and exhaust systems....I couldn't.  A nice paragraph in tech101 talks about the pros and cons of both cast log-type exhaust manifolds  and fabricated tubular-style exhuast manifolds, however.  Maybe I'm looking in the wrong place, Dan, can you point me to a specific part of that link ?   I'm willing to learn.)

  Pressure
  Power to create the pressure
  Heat created from producing the pressure that reduces density and mass air flow
  Detonation caused by the higher heat.

  They all come together and if you make no attempt to optimize the system they all get worse and limit power.
  (Dan, optimizing the system was not the subject of this discussion.  Applying traditional methods (aggressive cams, increased compression, porting & polishing, low restrictions intake and exhaust manifolds, etc.) of increasing hp to the turbocharging arena is the subject.  If you are inferring that applying traditional methods to a turbo engine is "optimizing", then THAT is where I disagree.  I maintain that increasing boost is easier/quicker/cheaper than those traditional methods of increasing the power output of an engine.)

  Again, anybody wants an explanation feel free to ask.
  (Looks like we've both just about explained ourselves out....)
