Thanks Wilson. What is the remedy for that 'limp' mode? If its not too
great, I think I'd risk the K&N, and let it seat in with some moderate
driving to get the oil off, no?
You are correct on the 911, visceral is the perfect word. I'm hoping the S4
will give me enough excitement when I leave the 911 at home!!

I imagine we are in similar boats. You bought the S4 as a street
machine, and you have some other 2 door car that you view as "the sports
car." The Sports car gets used for those more aggressive days, perhaps
on a track if the opportunity permits. The S4 is a 4 door daily. no
slouch, but still a daily.
in any event, if you wish to adjust he suspension, the bilstien/HR combo
is often recommended. If you want to go coil-overs, Stassis is
recommended. My S4 currently has the KW Coil-overs installed... using
a KW "A6" spring up front and a KW "A4" spring in the rear. They give a
street ride, and definitely not what i would want at the track... but then
setup would be very aggressive. the Stassis owners seem to do more to
their S4 than I intend to.
Some of us upgrade the rear sway bar. the neuspeed is popular, I have
one of those. it has two settings.
I use the Axxis ultimate pads for stopping. they work well enough for a
street setup but are dusty as can be. (well, not hawk blue dusty, but
Read up on torn throttle body boots and F hose problems with the 2000.
You may elect to just replace those with Samco hose parts and avoid the
headache before it even shows itself. I have the samco parts on my car
and they've been reliable. Next have a look at those diverter valves.
they're next to be replaced. search around the audiworld site to see
which ones you'd like to use as replacements.
Dump some fuel injector cleaner in the gas to avoid misfire conditions.
Finally, you may wish to reconsider that K&N filter. I don't recommend
them, others will disagree. Your '81 911 does not have a MAF sensor, and
a K&N probably works well in this situation. A MAF sensor sits along
the intake path after the airbox and can pick up oils from that trusty
K&N. Those oils can eventually damage the ability for this sensor to
read air flow data and as such, the computer may become irritable and
can even through your car into what we call limp mode. This
effectively prevents any signifigant boost from being
generated in order to "protect" your engine. The car will accelerate,
but very slowly in this mode.
