RE: More on A4 30v supercharger

[Scott Stiles <scottst@microsoft.com>]

Questions:
- how'd he come up w/5psi?
- you say he "keeps the longevity of the engine intact". how does he define
longevity? 
  - how many miles has he put on a test mule?
  - does he have any first-hand knowledge to the durability testing Audi has
done w/their engine? e.g. how much "margin for error" have they built in? My
guess is "relatively little". I'm also guessing that when you take the
engine a certain percentage past it's designed HP levels the projected
lifespan of the engine decreases exponentially. *Especially* in the case of
NA motors.
- how much (in degrees) does the supercharger warm the intake air?
- I guess what I'm getting at is: where does 5psi fall in the tradeoff
between engine longevity & HP in the 30v application? I doubt he can answer
this question.

- Will an engine rebuild cost me more than the $$ difference between my 30v
and an A4/S4?

]Just talked to Tony Ricci...he said the supercharger puts out 5lbs of
boost.
]5lbs = about 270hp.  He kept it this way to keep longevity of the engine
]in tact and not to mention worrying about extra added heat.  He said if one
]were to get an Avantgarde front bumper and modify that, you could probably
]fit an intercooler in there.  He also said he'd be willing to pay money if
]someone could find out how to fit an intercooler in the stock setup
]without a lot of hacking and serious modification.  I think I will be
getting
]one soon after they come out and other people have used them.
]Later!
