Turbo; JH or PL?

[jdbubb at verizon.net (Dan Bubb)]

This is a ridiculous arguement.
Simply turn up the boost!
At what point can you no longer turn up the boost?
5 psi? 10 psi? 15 psi?

An unmodified engine will work a lot harder and the parts will get a lot hotter than an engine with airflow enhancing modifications for a given boost level.
An unmodified engine will fail at a lower boost level and lower power output than a modified engine due to the amount of energy lost pumping against all its restrictions and it's higher internal heat.

At what point do you need to improve your engine's airflow to sustain a higher boost?

Maybe you can be specific about what maximum  boost and what octane gas your philisophy applies to?

   It would seem that way, wouldn't it?  In fact, it probably will help in an FI engine.  
  (I've never said it wouldn't help, what I have been trying to say is that it is unnecessary.)

   My point is this: there is an "easier" way to get more torque out of a turbo engine than P&P:  just turn up the boost about 1 psi.

    It seems to me that porting and polishing would be useful with either FI or NA engines. 8 or 16.

    By increasing the laminar flow and decreasing the turbulance of any air flow would be beneficial to power and efficency.
