Well, its just less efficient.  Unless the efficiency is down at like 45%.
But these turbos are no gems either. I *heard* the highest efficiency
puddle on a map is like 68%.  Thats as good as it gets anyhow...And as for
turbos and efficiency goes, that straight up sux.

Whattya mean?  You can see on the pump when they refilled the underground

With varying qualities of gas with the same octane rating, what is
considered good gas and whats lousy? I have no idea so I run Fina(or
Supertest brand) in the escort and Mobil in the Pinto.  I heard Mobil sux
too, but I never hear whats supposed to be better.

 The advantage of using the KS is that even after the mods

Thing about the KS that bothers me its alot more things than detonation 
set it off(ie, Motorsport roller off the top of my head).  thats why I
dont like to run it.  If the car is set up rite, it should work without
it, and even if something does happen, unless your really not paying
attention, you should be able to react and get off the throttle quick
enuff to atleast equal damage prevention capabilities of the KS.  Contrary
to maybe popular belief, it takes more than 3 seconds of detonation to
blow a head gasket.  I beleive its a good addition to a high risk
situation when being driven by people of varying intelligence(the way Ford
has to approach the situation), but I would think that almost everyone on
this list would have the sense to atleast let off if they heard
detonation. And that stategy will not damage your motor if you make an
effort to correct the problem.  Damge will occur if you bonehed around
like that for a year.
Hell, the pinto doesn't ping, but it went from running a 14.3 to running
13.9 on its first nite at the track when I dc'd the KS.

Thats true.  And I was jus asking what you thouht the relationship mite me
between TPS and pinging.  Thinking if the TPS was set too high that the
car may be going rite into the part throttle ignition tables too early
making it knock.  The solution is not to hook up the KS and turn d0own the
boost when it never did it before.

well, as soon as you do ANY mods to your car, you increase the chance of
breakage.  Cylinder pressure causes breakage, and anything you do to
increase power(cylinder pressure) increases that chance.  It jus depends
on what you feel is your threshold of reliablity you want to accept.
