Turbo vs. Supercharger.

[jdbubb at ix.netcom.com (Dan Bubb)]

Well, that's the exception! It is a fact that superchargers have much worse
efficiency than turbos. But, clearly, in this application it works. Maybe
they don't care how much power it takes to turn the super and maybe
nitromethane works really well at really high intake air temps. Or maybe the
air temp doesn't matter when you're pumping as much mass fuel flow as mass
air flow!!! (not really but close ;^)
In any event this really is the exception and NOT very relavent to street
applications.
I stand corrected on the point though.

  A million opinions!
  Superchargers tend to be less efficient particularly at higher pressure
  ratios. So, they aren't as good at making really high power.

  YOU'D BETTER TELL THAT TO JOHN FORCE, HE COULD USE SOME ADVICE ABOUT NOW.

  OTOH a big really high power laggy turbo is the last thing you need for an
  autocross car. Superchargers, particularly positive displacement types,
have
  fast response.
  The primary issue then is quick response vs. power producing capability.
  There are a million secondary issues!
  just my .02

  AS FOR THE REST, I WHOLEHEARTEDLY AGREE WITH DAN.
  HAVE FUN!
