This used 1989 Mustang with a salvage title replaced my beloved 1989 Taurus SHO cruiser that #1 son Matt totalled.
Although it was a quite step down in performance compared to the SHO, the Mustang has survived 13 years and 125,000 miles of
abuse by me, my wife and 3 of our kids.
It was driven many brutal Nebraska winters on studded snow tires with 300 pounds of 455 Oldsmobile cylinder heads in the trunk. #2
Son Adam drove it while delivering Papa John's pizza. Our only daughter
Ali drove it to her high school classes during snowstorms with
the rear window completely torn out. We don't want to know what #1 son
Matt did to it.
Confessions of vaulting over medians at 45mph, fishtailing sideways into trees, and many other unspeakable acts of mechanical abuse
against the Mustang have since been revealed.  "Dad, what does the flickering
OIL light on the instrument panel mean?"
Like a badly worn pair of old shoes that are so comfortable yet embarrassing, we just could not part with this car that is a part of our
family.
After being outrun by a Honda (a 4 door Accord -- not an NSX) driven by a teenage girl 2 years ago, I had enough of driving a tired 15
second wannabe cruiser.  Plans to resurrect the car cosmetically and to make serious upgrades in power, suspension, and braking were
set in motion.
I stumbled onto our used Incon 800TTI system by responding to an ad posted on Corral.net by an honest young man from New Jersey,
Al who was overwhelmed attempting to respond sincerely to the people inquiring about his kit, most of whom had no knowledge of
what they were getting into. I had cash (for the 2nd time in my life) and a trusted and knowledgeable friend 50 miles close to Al. I
thankmy true friend John R. for volunteering his personal time and effort to drive to "Al's" house to inspect, evaluate, and offer me
his opinion on the kit.
There were no disappointments when the kit arrived. The parts were neatly packaged and labeled as Al had promised, the attention to
detail and the quality of the components was obvious.  My favorite UPS man I affectionately call "Bubba" who (at 6' 5", 280# we could
use on the NU offensive line,) did not appreciate lugging this 149 pound box of stuff 100 feet to our door.
Installation went smoothly but took over 30 hours working by myself.  I worry a lot.  The engine fired instantly but developed an
erratic idle that wavered between 600 and 1200rpm, and wanted to die after throttle lift-off.  This was cured completely by
performing this simple procedure
Idle fix.
I extend my sympathy to the people who lost money dealing with Incon.  Yes, their financing methods were unethical, their
capitalization was poorly managed, their efforts to fund future projects was bungled.  Incon, as a business, earned the right to fail and
be sued.

At the same time I have not had any of my fellow Incon owners tell me they have issues with performance or reliability with their
system.  In my opinion the people at Incon excelled in design and engineering work, yet failed miserably in marketing and financing a
good product.
UPDATE!  September 2003. Problems? What problems?  Detonation above 3200rpm is obvious, and when I park the car it leaves
puddles of coolant like a puppy leaves puddles of...  The engine feels like it's running on 7 1/2 cylinders.
Problem #1
detonation
Problem #2 headgaskets
UPDATE!  November 2003. The headgaskets have been replaced; ARP head studs, Denso Iridium IK24 spark plugs, and a Vortech
bypass valve have been installed. Base timing is 6*, the actual boost pressure is a work in progress, local 91 octane is in the tank.
After many dollars and many hours of work this has finally turned into one sweet ride.
UPDATE!  January 2004. A bad day at the dyno.
The combination:
DSS prepped + .030 bare block. The DSS folks are knowledgeable, honest, no BS people who are a joy to deal with.
DSS low compression SuperPro pistons, 8.7:1 calculated compression ratio, .912" floating pins.
DSS main girdle.
Total Seal gapless rings.
Original 125,000 mile crank, micropolished, chamfered oil holes.
Summit H-beam rods. The quality of the machining and finish of these rods is flawless.  ARP studs on mains and heads.
TFS O-ring heads.  All sharp machined edges in the combustion chambers were polished to a .040" radius with a Cratex 240 grit rubberized
cutter.
Crane 2031 cam.  Idles nicely at 750rpm with a noticeable lope, makes power right up to the current 6200rpm rev-limiter setting, delivers
the same 14mpg the stock 5.0 and AOD made in commuter traffic.  I haven't driven enough steady-state highway miles to confirm fuel
consumption, but mid 20's seems realistic.
TFS-51500003 R-series upper & lower intake.  Was this a better choice than a GT-40 or a stock intake?  I don't know.  The Denso
IK24 spark plugs burn evenly, the engine revs freely to the rev-limiter and is driveable and well-mannered in traffic and starts fine in
sub-zero temps.
TFS 1.7:1, 3/8 stud mount rockers, p/n TFS-51400511, adjusted to 1/2 turn clockwise from zero-lash and TFS 21406750 pushrods,
6.75" long, were essential with this mix of parts..
75mm Edelbrock throttle body & EGR spacer.
255lph in-tank pump, 36lb/hour injectors.
Crane HI-6 ignition with boost retard turned off.  I've used MSD ignitions for over 20 years, but I chose the Crane because I
could set the rev limit with a screwdriver -- no more "pills".  I'll use the Tweecer to reduce timing between 3200 and 4500.
Tweecer! Just installed, am trying to learn.
Tweecer 101 and online forums.
Off-road H-pipe, no cats, smog pump eliminated with an idler pulley, Walker Dynomax 2 1/2" mufflers, the sawed off turn-down
exhaust stubs will be replaced with LX style pipes soon; this configuration resonates too much between idle and 2000rpm.
Tremec 3550 5-speed transmission, Pro-5.0 shifter, stock driveshaft with original u-joints (#@#!) stock 2.73:1 8.8 Trak-Lok differential.  
Moser 28 spline axles.  Yes, I cross my chest and say a few "Hail Mary's" every time I stand on the throttle.
Lakewood bellhousing, 15 pound aluminum flywheel, toasted Centerforce dual friction clutch disc and pressure plate, adjustable clutch
cable.
UPDATE! Replaced Centerforce disc with Ram 8 puck metallic.  Like a pin drops into a hole -- in or out, but no trace of slip.
Welded rectangular subframe connectors.
Thank you Kent, ENGINE DYNAMICS, 402-435-1259, for your excellent machining and balancing work.
BFG 275/40-17 drag radials on generic 17 x 9 Cobra chrome wheels.
Necessary? I think so.  Wheelspin on demand at 90mph on street tires has great entertainment value, but makes this project moot.
17 psi inflation has been a good compromise for cruising with these very soft compound tires. Full-throttle above 3000rpm in 1st,
2nd, and 3rd gear still overpowers their ability to grip. The stiff suspension prevents weight transfer, the tires are fine.
The width of the contact patch at 17 psi is over 10", I have not probed the limits by lowering the pressure further in street use.
BFG suggests a minimum of 12 psi for drag strip use only. In BFG I trust, I can live with tires that last only 3000 miles.
Update. If these tires survive 2500 miles with my current driving habits, I'll be lucky.  Pantera's have a wonderful 40/60 weight
distribution, and this is not a Pantera.
Maximum Motorsports Torque Arm
The MM arm, panhard bar, and lower control arms gave the most dramatic improvement in handling I've ever experienced in 37
years of driving.  I had to relearn how to drive the car. Variable rate springs, Koni yellow struts & shocks, and numerous steering &
suspension tweaks were done.  Highway, street & autocross manners came 1st, good launches for drag racing came in a distant 2nd.
Straight water cools better
than an antifreeze mix, but.....
Speedway Motors Ron Davis 28" aluminum radiator
I have not seen coolant temps over 180* since I installed this "heat exchanger", even after 3 back-to-back full-throttle runs to 120mph
during 100* Nebraska weather with the A/C on. Buy one. Keep the stock fan shroud, replace the viscous fan clutch with a Hayden, and
blend a mix of distilled water, water-wetter, and antifreeze that works best for you. The original & loud stock OEM mechanically driven fan is
more than adequate in keeping the engine cool.  
Proform shift light Just try to stay in your lane, watch the tach, and shift. This easily installed device bursts a brilliant amber light when the
engine rpm you select has been reached. This has changed my driving style. Buy one.
Autometer boost/vacuum gauge that accurately reads 13" of vacuum at idle and whatever the boost is currently set to. I have not tried to
test boost in 4th on public roads which would require full-throttle at 120mph.  I'm a lucky 53 year-old with no points on my drivers license
with an insurance agent who, I think, actually likes me.
Drove way out of
town to make a run
on my favorite 2-lane
on a 60* Sunday and
was overwhelmed
with the ability to
blow the tires away
in 2nd at 50mph at
3200rpm.

"Wow!" I thought,
"picked up another
100hp somehow,
never did that
before. It must be
the cool air!".

Despite being 50%
Polish, I'm somewhat
cynical and not a
total idiot.

I made another run
while eyeing the
rearview, only to
realize I was blowing
away a "tire."
The Trak-lok that once was gimpy on slick streets was now certifiably toast.
Replacing the clutch pack in this diff should not take more than 2 or 3 hours, right?  If there are any Ford tech's reading this, what is Ford's
flat-rate for this job?  The special Ford screw that retains the cross shaft sheared at the threads as I gently, lovingly, loosened it.  I spent
another 4 paranoid hours scheming "how the hell do I remove the remaining stub of this screw?"  Magnets were worthless, hammering on
the cross shaft in an attempt to "shear" and remove what was left of Ford's special screw proved equally futile.  What is the best way to
remove the .186" diameter pin, about 1" long, stuck in a blind hole in the carrier?  I drilled two holes as close as possible next to the cross
shaft in an attempt to shear the remaining pin.
The shaft came out with
persuasion from a flat punch
and a claw hammer and had
mushroomed +.002" within
1/2" of it's end and should
have been replaced.  I cheated
and ground it to fit.  After 3000
miles there are no bad noises
and the tires light evenly.
Water/alcohol injection is the final project on the list. The benefits are tremendous, the cost is low, my thanks to Steve Monroe and his
Buick GN guys running 24# boost.  I'll settle for somewhat less.
Favorite web links:
Brian Renegar's most excellent www.twinturbostang.com site.
Click on the "video" link to see his short-shifted 10 second run get drowned out by a mosquito car. Brian and I have differing opinions on
how to achieve results.  The score so far is Brian 2, Chmielewski 0.  He's a good man with an analytic approach, and I suspect he'll be near
the 9's this year.
Bob Cosby's excellent Incon install article was a great help.
Trent's most excellent www.turbomustangs.com site.
Don't like 'Rice'? Too bad; John Shepherd's '91 AWD Talon just might change your mind. There's something about a streetable 8
second ride that has my attention. Check out John's
9.39 @ 155 in-car pass.
Although John Garners' car is belt-driven, I do love these black convertibles.
Our daughter Ali just had to borrow the CAR for her High School graduation pictures.
In the beginning.....
Some of the perps, from the left; Ali, Adam, Alex, Katie the "hand whore", Matt, and Kikuko; an innocent bystander.
What's up with the little ankle-biter dog? On guard, Bela! This 8 pound, 3 year-old Toy Fox Terrier was the best dog we ever had. He never bit
anyone intentionally and preferred to lick humans into submission. I would trade this car in an instant if it would bring back this sweet,
intelligent and loyal little guy.
If you served in the 90th Aviation Company between
1970 and 1972, please
e-mail me. LeRoy Wilkins, Curt
Heim, Mike Steeger, Kenny "The Heat" AGPU Master,
Herbie Revestir, are you out there?

In the rare chance you are I'd love to hear from you.
The image quality varies greatly, my apologies. Some pictures are 300dpi, 24 bit true color scans of old throwaway Kodak pictures, some
were taken with a battery-devouring HP digital camera at 640X480. The really decent pictures were taken with a Sony
DSC-F707 at
1280X960.  All pictures were compressed excessively for web friendliness.  What, you're still using dial-up??
Thanks to our 13 year-old Alex for teaching me basic HTML.
Thanks to my long suffering wife Delores for putting up with me for 33 years.
Thanks to Chami.com for their excellent
HTML-kit HTML editing program.
