Ann,

   Glad to see some other owners popping up with Big Reds.  Gawd aren't
they fun?  I have only seen one 96 Stealth and it was at the Wisconsin
Gathering so I don't know what they have different other than the rear
wing is a little changed.
   One sure way to tell is if there is an ECS suspension button on the
dash or a Tour/Sport light on the instrument cluster.  Also, if there
are a bunch of little black boxes on top or near the top of the strut
towers.  I just have wiring harnesses that end there since I don't have
that but they still left all the old wiring harnesses in place.
   For AWS I was under the impression that all VR-4 cars had them
(except maybe that first year or two) but can't remember about the TTs.
Perhaps they didn't get that until the second gen.  I never followed the
Stealth much since I have a VR-4 but I probably should.
   When I hit Pep Boys or Sears they seem to list the VR-4 and TT/R-T in
the same category for all years and call it 4WD but this tells us
nothing about the steering.
   When I had the wheel off of mine and looked in the wheelwell in the
back there is some noticeable hardware added for the AWS cars ... more
sensors, a rod that turns near the axle itself I think, and some other
junk I have no idea what it is yet.  I think CAPS might have number if
you plug in the VIN but a good mechanic should be able to tell also.  I
am neither.

Does anyone know when (or if) Dodge started eleminating some of the
special features of the TT as it was phasing out the car?  I've heard
that the 95 TT might not have such features as AWS and suspension
control.  How can one tell?  Are there certain production numbers on
vehicles or is there a date after which these features were eleminated?
Thanks.

Subject: Team3S: Cape Cod 2001 Gathering pictures

Here are my pictures from last weekend's Cape Cod Gathering.  Other
people took good pictures as well.  This was more of a trio from
Pittsburgh, PA to near Sandwich, MA and since the Fall leaves are nice
that time of year we took extra pictures of them.  All of them were
taken by me and all of them on the road were taken by me while driving
- -- which is probably illegal somewhere (grin).

The trip in general headed from Pittsburgh through the middle of the
state, into southern NY, then through Connecticut, Rhode Island, and
into Boston for the Blue Man Group show and down to a lovely Bed and
Breakfast on the Cape.

Then a 3/S Poker Run Saturday morning followed by our car show and then
the Eric Bowden celebrity award banquet then back to the ice cream shop
afterwards.

Sunday was F1Boston go karts, then a stop at Foxwoods casino in CT, then
Sherwood's for ribs outside NYC.  Back through northeastern and central
PA and back home.  The road signs are to help people know where the
shots are from until I rename them logically.  Enjoy.

Tech related stuff?  At the car show people were asking what fit on
other cars like wheels, tires, turbos, boost controllers, data loggers,
seats, stereos, etc.  Lots of good learning when people just chat and
ask questions.  Ask anything that you have questions about when seeing
the cars and I'll explain as best I can.  Enjoy.

My web page will answer all the questions you may have on 2nd Gen R/T TTs.
AWS was deleted for '95 & '96 on the Stealths.  Not sure about VR-4s
although I believe all VR-4s from '91 - '99 had AWS.  I hope someone else
chimes in if this isn't the case.

I was looking over your site an production volumes and have a question
about the missing VIN numbers --- have you run a carfax on any of the
numbers or checked with a dealer data base to see if any exist.

I assume you are talking about the '91 and '97 missing #s.  We know at least
some of the missing #'s are actual cars out there since one of the guys on the
3SI board owns one of the missing VINs ('91 R/T TT).  Mike Reid only has the
missing sequence #'s and therefore requires you to guess at the check digit
which could be 0-9 or X.  This is assuming you know it is a Mitsubishi vs
Stealth and a TT vs base etc.  Once you enter the complete VIN correctly into
carfax, you will know what kind of car it is and where it was last titled etc.
If anyone would like to volunteer to go through the missing VINs to determine
how that particular car was built, email Mike and he'll give you all the missing
VINs.  You might get lucky like I did while decoding the '95 R/T TT in that all
the missing VINs from 1995 were Dodge Stealth R/T TTs which only left the check
digit as the only variable.  It was made even easier for me when I found a way
to get the whole VIN from Chrysler given just the sequence #.

Subject: Team3S: New Blitz Dual Turbo Timer DC

Installed the timer today on a clients car. He's very happy with it as he
runs a bleeder valve and never knew what boost he runs on. This new timer
comes with a boost alarm setting when hit and the display turns red and give
a double peep (like the Blitz boost controller). Needless to say that it
peeped at 1.05 bars :-/ It now also has a bar graph that shows time or boost
graphically. Nice in peak mode as actual boost is still shown on the graph.

It's the same price like the older DTT and comes with the timer box (mounted
on the chassis behind the ECU) and the control panel.... nice thing and the
customer really loves it.

Subject: Team3S: BOV Dump Strait to Atmosphere

Has anyone noticed any strange effects when venting your stock BOV strait to
the atmosphere?  I'm having a bit of a problem with idle control, but it
seems to be slowly disappearing.  I did have to reset my ECU to clear a CE
light because I forgot to plug in the MAS (car ran kinda rich because of
that :-).  So I'm wondering if I just have to let my ECU re-learn or if this
is a permanent bug associated with this mod.  Thanks!!

Its not a bug, when the BOV opens, you vent metered air..and the ECU gets
confused..and -can- stall.  If its an adjustable BOV, it might just be set
to lose.

Subject: Re: Team3S: BOV Dump Strait to Atmosphere

From what I've heard, it's a problem that comes with any aftermarket BOV that replaces our BPV.  A Blow Off Valve will vent off air
that is accounted for by the MAS.  Our By-Pass Valve vents it back into the intake so the air that was accounted for goes to the
engine.  With an atmosphere venting BOV, the air is lost and can result in a rich A/F ratio which can result in stalling.  This is
why the GReddy Type-S BOV (actually a BPV) is a good option.
There is also theory that the turbos spool up better after shifting gears if you have the BOV vent into the intake instead of the
atmosphere because you don't lose as much intake pressure, but I don't know if that's confirmed or not.
Good luck, let us know if the ECU evens the idle out,

Subject: Re: Team3S: Re: Ceramic brakes?

you need to direct the questions to Geoff --- the carbon/carbon
setup was for rotors and pads only and it's not just a matter or
wiping the water off. Appearently the carbon absorbs moisture
and it must be driven out through heating of the rotor/pad so
for street use you would have to preheat them before you use
them --- on a track you can heat them on the warmup lap.

Subject: RE: Team3S: BOV Dump Strait to Atmosphere

I think the original question was if there was any strange effect when
venting the stock BOV (correctly called a turbo bypass valve) to
atmosphere ... not if an aftermarket one dumps to atmosphere or the
intake.

I vented mine to see what it was like.  Got a cool *whoosh* sound when
shifting gears, lost metered air, did not stall, did not run rich.  It
did not run at all when I forgot to re-attach one of the hoses though.
It ran fine under no boost but as soon as it hit boost range I lost
power instantaneously (the sure sign a hose blew off or was not
connected).

My idle is fine and I tried to get the list to determine how far in/out
their idle set screw was set but nobody ever responded.  I turned mine
all the way shut (clockwise) and then backed it out until the idle
leveled at the correct 750 rpm.  I believe this was three full turns but
I can check again.  So if yours is all the way out (barely in) or all
the way in and is at 750 rpm then there is something wrong.

There is nothing wrong with dumping to atmosphere though other than you
lose metered air ... but since you are not paying for it then it just
makes a nice sound.  You only lose a little performance since your
engine needs to suck in that much more air.

The ECU did eventually learn to control the idle better, took about 15
minutes of driving though.  As far as performance goes, I can't tell any
differance either positive or negative (but it sure does sound sweet, I can
hear blow off by just reving my engine up to 3 grand).  I have heard 2
theories on how this effects performance though: 1) the loss of boost
pressure to the atmosphere keep the turbos from staying well spooled  2) the
turbo is able to free wheel better without the pressurized intake while
venting to the atmosphere (kinda like it's a bad idea to put a ram air
intake on our cars).  Any thoughts?

I hope so, since a properly functioning BOV (open or closed to the
atmosphere) has no airflow through it at idle and should not affect
idle in any sense. Having watched the fuel trims many times using a
TMO and PocketLOGGER, I know that the ECM reacts within *seconds* to
changes in air flow or fuel mixture.

> I have heard 2 theories on how this effects performance though:

The *exhaust gas* spools the turbo. The BOV has no affect on this
EXCEPT when it does not function correctly and allows high pressure
to build in the intake track, which tries to slow the compressor
wheel, possibly to the point of damaging the turbo. This action is
exactly what the BOV (or more correctly a by-pass valve) is designed
to prevent. The BOV relieves pressure in the intake track when the
throttle plate is closed quickly. The triggering condition is greater
pressure in the Y-pipe than in the plenum (throttle plate closed
right after a "boosting" situation).

The turbo only "free wheels" when the exhaust flow/heat is low, such
as at idle and very low RPM cruising. Look at compressor flow maps
and you will see that almost no boost is produced when turbos spin
less than about 20,000-50,000 RPM (depending on model). A properly
functioning BOV does not affect this. Again the *exhaust gas* turns
the turbo wheels. All the engine intake track (output side of turbo)
can do is try to stop the wheels from turning if a BOV is not used or
is not functioning correctly and the throttle plate is slammed shut
under boosting conditions.

I have never heard of ram air, which has a minimal affect at speeds
less than about 80 mph, as being bad, forced induction or not.
Remember the "rammed air" is goint INTO the turbo. The higher the
intake pressure, the higher the potential output pressure from the
turbo. "Ram air" is a good thing for turbos.

I've got two questions.
1.  Is it bad for twin turbo setups if the intercooler piping is longer for one turbo than the other?
2.  Would it be more effective if the intercoolers were before the turbos?

I was just looking at Jeff's page with the cut-away engine shot and it just popped into my head.

After I did this mod and reset the ECM my engine died a couple times when
returning to idle from normal RMPs (i.e. 3000-3300), like it was having a
hard time "catching" itself before it died completely.  I also noticed my
engine's idle speed lowered by about 100 RPM.  This behavior persisted for
about 5-10 minutes.  If the ECM can react that fast, do you have any idea
why this would happen?

No !!!! the output from the two turbos merges at the 'Y' pipe so the pressure
is equalized anyway.

> 2.  Would it be more effective if the intercoolers were before the turbos?

No again --- while you want the intake air as cool as possible there is no way
 to cool the intake charge below ambient unless you use an AC unit. The
turbos heat the intake charge by compression heating, heat transfer from the
turbos and the inefficiencies of the turbos ---- the goal of the intercooler is to
remove as much of the heat added by the turbos as possible.
