Yet another question for you Turbo Experts.

[Stetina]

Hi Javad and everyone,
This is something that I cannot quite come to grips with : The K26 can
support enough airflow to feed 300 hp.  The K24 can make a purported 285,
but has a quicker spool up (all things being equal).  When the stock CIS
airflow meter "tops out", its "maximum measurable" airflow can be matched
with only enough fuel to support around what, 230 ? 240 ? 223.89647 ?!!?
Any more airflow then this cannot be used. Since each of these turbos can
support ALLOT more air then the car's fuel system can match,  why would
anyone want to use the K26 ?  Since you cannot use near the potential of
either unit, I don't see how "hi rpm performance" can be affected at all...
its just a matter of delivery.  Slow or fast.  I certainly vote for fast.

This additional injector stuff is great. Keep talking everyone. I read on
Scott Mockry's site that the fuel distributor in the old CIS cars is really
a 6 cylinder piece with one line plugged... (haven't had that part of my car
apart yet).

There seems to me to be 20% more fuel available pretty easily.  Can 20% more
fuel feed 20% more boost ? I think so. Lets see, 230 x .20 = another 46.
230+46= 276.  The impressive part would be the torque increase. Not bad, now
your starting to use that K24 (or almost a K26). Could that line be
controlled with a solenoid that is activated only a pre -set elevated boost
pressure and/or WOT ?  Everything in essence would still be controlled by
the already modded computer.  Sounds sorta straight forward ? Certainly not
perfect, but I'd be willing to bet that the initial rich spike caused as the
line is triggered to open (and maybe before max boost is reached) wouldn't
adversely affect the car's performance.  Turbos like a little extra fuel
when they're really working...Could that line be split into several / many
smaller injectors so proper fuel distribution could be achieved ?      ?
Well its an idea anyway...

I think these other additional fueling controllers you have mentioned sound
mighty enticing. I for one will certainly look into what's been put forth.
Thanks

My 87 5000TQ MC-11w/ K26 is running 15 - 16 psi (I know it really needs a
bypass) on the_street_. Naturally it doesn't see total boost much of the
time.  It has pretty substantial lag but its nothing like when it was stock.
But on the highway it goes from 80 to 120 right now. Did I mention the old
goat has over 225,000 miles? Right now I'm changing to K24 and 2 piece EM.
Low cr engines tolerate hi boost allot easier then high ones.
The bottom end of these engines (MC et al) is probably laughing at how
little they are being pushed. They need more fuel and better charge cooling
to embarrass those pesky 3B /AAN 4v units hauling those Tank Mobiles
disguised as cars!       C'mon I'm only teasing!

I still want a rear swaybar but Addco and Suspension Techniques don't offer
one.  Oh,one of these firms shows one that will fit an 83-85 5000. Anybody
know the difference between those and the 86 - 90 type 44s ?

Joel        and now even more BS...
87 5000TQ (old gold goat w/ NINE Fuchs) well you gotta have a spare and
winter tires too
90 200TQ (wreck=lotsa spares?),
91 200TQA 20v (really a tank in auto clothing)! still a lovely car
79 323i w/ schricked 2.7  & 2500lbs (lovely noise, no turbo, no quattro, but
still quite interesting)
