Is your blow off valve the original stock unit?
They have been known
to leak although at typically higher psi. Also,
did you make sure all
your intercooler hoses and Y-Pipe hose are
tight?

Well, this is a very rude test
as it could damage your car ! Stay away from
doing this.
Take the
advice of the messages before and test the wastegate actuator. If it
is
working fine, then search a leak anywhere in the IC piping, bypass
valve,
y-pipe. I remember a guy who had a small crack in one IC rubber pipe
and it blew
off all pressure over 9 psi.

the problem being if I'm unable exceed 11psi? (Even

Only if the hose leads to the WG actuators. All other leak in
the after-turbo
path causes a loss.

I'm sorry not to
be of more help for you but I'm positive that you'll find out
the problem.
Changing the rear WG actuator with it's lever attached looks very
complicated
for me (with the turbo in the car). Also a new one is stupidly,
horrible
expensive (more than $200 here). If you need one, try to get it from
a
salvage yard.
Good luck,

Subject: Team3S: Flat
Spot Revisited
All,
Sorry about the HTML, didn't even know what it
meant. I switched to Plain
Text in my brouser. Hopefully this is
correct.
Thanks for the responses, I'm including some additional info as per
Rogers
request.
Prior to installing the 13g's, running an AVC-R, bypassed
cat (for testing
only of course), FIPK, and .032 plug gap, any attempts to
run over 1.1 bar
resulted in what I felt as noticable ignition retard.
To exceed 1.1
resulted in even more noticable power loss above 4000.
While
installing the 13g's, I installed an EGT in the back manifold before
the
turbine and gutted the pre-cats (for testing only of course) and cleaned
up
some of the weld on the pre-cat manifolds. I also installed an AFC and
a
260 lph fuel pump, but held off on the injectors just to confirm if
the
stock units were undersized (360cc stamped on the stock injector).
The
results were dissapointing, power improved slightly but the ignition
retard
was still occuring at 1.1+. Additionally, on one 3rd gear WOT
run my EGT
hit 950 C. Finally convinced, fooled by the O2 reading
saying I was rich, I
installed the RC 500's. WOW...the flood gates were
opened, even at 1.05 bar
the power increase was significant by
comparison. I've tested up to 1.3 bar
with no noticable retard, boost
is now limited by the 13g's inability to
hold 1.25+ in the lower gears.
Using the EGT, and the AFC, I've dialed in
900 C at WOT with no problems
(aside from the low throttle flat
spot).

DaveT/92TT

RE: Team3S: 2500-3000 Flat spot
I had 13Gs and stock injectors
w/VPC. The most boost I could run was 20
(1.36 bars?) PSI when the
motor was cool (at the track) and 18 PSI with it
was hot (street
driving). At the track, fuel was 100 octane mixed 50/50
with 93 octane
pump. Best E.T. was 12.40's. Switched to 550 injectors and
went
11.80's with 13G's. I found a huge difference with the 550's -
far
better than I expected.
On a VPC-equipped car, the "flat spot" is
very likely to be fuel related.
Case in point, after I got my motor put back
together with REAL COMPRESSION
in all 6 cyls, with the street chip VPC EPROM
I notice a pronounced lag all
the way to 5000 RPM before the power kicks
in. Never felt it before because
the car just wasn't that fast.
Switch to the race EPROM and the power comes
on hard at 2500 and pulls all
the way to 7500.
It's been said that larger injectors sometimes deliver
too much fuel at the
low end. You could be seeing that with the AFC
setup.

Wouldn't a leak cause the actuators to see less pressure and

Correct. If the wastegates are
stuck closed you will over boost, with them
open you will be "dumping" most
the boost into the exhaust. So they could
be stuck open. Either
way they should move. If not there is a problem. It
could also be a
problem between the turbo and the intercooler. Maybe a
slipped
hose.

Yes, if it was partially open.
But there are other things that could just

as an I/C hose leak. In my opinion, the
stock BOV is not the
problem. The way the stock BOV is designed, the more
boost there is,
the less chance it will leak. That is because the valve is
pre-loaded
to 5 lbs and uses boost pressure to keep it closed.

boost check valve that tends to chatter

vacuum and boost. Since the check valve
only opens when vacuum is

Hi Marc;
Sounds like
you've covered the easy fixes. Darn eh!! There is a whole chapter devoted
to
ABS problems in the manual...so it could be a short, solenoid problem,
valve relay, etc,
etc. Maybe try cleaning the wheel sensors of corrison
(salt, rust, etc) if you haven't
already...you may discover something when
you do. If that doesn't work, consider paying
Mitsu to reset it/diagnose it
for you. If that doesn't work, tell them you paid them to
fix and they
didn't, and have them fix it again...yada yada yada.
Before going to
Mitsu, do the following and we'll see if we can diagnose it from
the
information you post back.
1) turn key to ON position....does it
flash 4 times very rapidly?
2) then turn key to START position....does it
remain lit?
3) then return key from START position to ON position....does it
flash 4 times in about
a second again?
Get back with the info
and I'll walk you through the manual diagnostics and see if we
can pin point
the problem.

The Blitz BOV setup often uses the stock BOV as well, so it could
still play a
rule here.
For the stock valve, it has a small hole in it
and therefore always leaking a
little. But Bob is right, the manifold
pressure keeps the valve closed (the hose
that runs to the BOV). If boost
goes away the pressure in the y-pipe pushes the
bypass valve open to release
pressure into the intake path.
Check if the Blitz BOV is connected before
the bypass valve or if it is alone.
There must be a cause why people are
installing it together with the stock parts
and I think it's smoother
operation. The Blitz BOV is a very quick opening
device and therefore also
somewhat hard to adjust. It seems to work good when
adjusted to soft but
mabye it is too soft and acts too early causing an unwanted
leak.
Go
step by step with your problem eliminating one point by another (make
sure
the wastegates are fully closing).

When running stock
injectors a bigger fuel pump doesn't help at all, but larger
ones definitely
need a bigger pump . I was able to run 1.2bars without any
noticeable retard
but runned into fuel cut at 1.25. Leaning it out with the AFC
caused no fuel
cut but more retard (hesitation feeling, power loss).

Due to my ignorance I had no
EGT and thought I'm fine leaning it out. As Meyer

of my pistons this way.

Dave, you did
the right thing and I wished that I had the knowledge then ! More
fuel means
richer and cools the combustion chamber to prevent the high
temperatures that
cause detonation. This is a way but not good because there are
still
restrictions. You went the right path and firstly removed the biggest
exhaust
restrictions and tapped the EGT probe into the right location. Only a
better
exhaust manifold design and some porting at the turbine housing of the
turbo
would make the job perfect. Then the next step is to add fuel choosing
the
injectors and pump and this is where you've seen the power comming. If
you want
go higher than now the larger fuel rail, lines and filter would be
the next
step.
Yours and my experience leads me to the suggestion that
my EU spec 3K does come
with larger injectors in conjunction with the 13Gs.
How can I find out the flow
rate of them still installed (where is the stamp
?)
For your flat spot I guess you're running way too rich in the lower
end. I read
about additional injectors (Dr.Grimms 3000GT in Turbo Mag.) and
it makes sense
as they are only activated when needed. It's possible that the
500's delivers
just too much fuel on low duty cycles and the AFC is probably
not able to
compensate this. I just hope to be able to get this working with
the 720 and the
VPC/GCC (gulp)
Later,

I was able to run up to
1.25bars with the 13G until I got fuel cut. Around
1.2bars the timing begun
to be retarded depending on the weather. In the
beginning peaks of around
1.34bars where no problems.
If you are just going to add fuel and more
fuel you'll misuse the fuel too much
and therefore not getting the most power
out of it. I highly recommend an EGT in
the exhaust manifold to be sure going
the safe way !!! As you have removed the
precats a big restriction is gone
and therefore the pressure in the manifold
should be lower. Detonation is our
enemy and we have to limit the restrictions
first before applying more
fuel.
Also good gas is not enough. The octane rating must be higher with
more boost
tahn 16psi (I lost the formula).

RE: Team3S: Fw: Wastegate Actuators?
If you blow into the top of the BOV,
you hear and feel a tiny, tiny amount
of air escaping from the .125"
hole. Inhaling on it, you get a small amount
of air as well. The
amount of air exchanged, however, is not proportional
to the size of the
hole, implying that there's an even SMALLER hole inside
somewhere. It's
obviously designed that way, because if you blow into the
top and cover up
the hole with your finger, the leak stops, meaning that the
valve is seating
properly.
Anyway, the amount of leakage is on the order of fractions of a
PSI and
wouldn't affect anyone's boost.
As far as the "whooooooong"
noise goes, this little leak could be the
culprit indirectly. Not that
the BOV is chattering - that's definitely one
of the clutch/brake boost check
valves making noise. But a leak anywhere in
the boost/vacuum system
affects the balance of of those check valves, so I'd
suggest that you guys
make sure all of the clamps are tight everywhere
before you start replacing
hoses. In my case, one the check valve hoses was
cracked right where it
touched the oil feed line to the rear turbo.
I'd bet that you could plug
that hole with a screw but MAKE SURE IT NEVER
WORKS ITS WAY OUT!

Like 2nd Gen DSM BOV's, the stock TT BOV also act as
a popoff valve,
usually limits boost to around 16psi. Sometimes would
go higher, like
it was stuck though. Once I REMOVED it and PLUGGED the
hose off, I
could get over 20psi boost. The stock BOV certainly can act
as gigantic
boost leakers/boost limiters. 1G DSM's do NOT popoff, that
is why they
often switch to the 1G version; or "crush" the 2G version so it
doesn't
limit boost anymore.
You have a LEAK somewhere in the high
pressure circuit, from turbos to
manifold; OR a bad turbo (includes
stuck-open wastegate). Totally
unhook the wastegate actuator (pressure)
line from the boost controller
to the wastegates. Then, car should run
"unlimited" boost; if it does,
it is a boost controller problem. If
not, see above...of course, you
have a good quality boost guage hooked up
without a leak in ITS line...

the AFC can compensate just fine with up to 560cc

just have to play around with it. Don't be afraid to
go as low as -20,
-25, -30.. on the dials with 550/560cc injectors. But,
make sure
you use a good volt meter grounded to the ECU ground or computer
software to
make sure the 02's dont drop to far.. my car runs well at .88-9v
WOT (ECU
grounded) on pump 93octane. Also a good idea to get a good EGT
gauge,
which will monitor your light throttle EGTs which DO vary significantly
when
you rich and lean up the car.
The AFC will be hard pressed with
720cc injectors though, but either a VPC/GCC
or VPC/AFC will work. The
720cc injectors in my car run great, nobody could
tell a difference in
drivability, and I'm able to bring the Injector duty
cycle down to more safe
levels under WOT (at 1.2or more bar, 550/560cc
injectors are maxed
out). And because of that, many people will experience
fuel cut above
1.3-1.4bar with the 550/560cc injector combination and 15G
turbos. Some
people have G-Force reprogram their ECU to get around that fuel
cut problem,
but IMO its only asking for trouble. It seems Mitsubishi
smartly
programmed fuel cut at 99% or greater injector duty cycle, to help
prevent
the injectors from staying open. So IMO its a good idea to leave
the
stock fuel cut (if you use VPC/GCC or AFC) to help keep the pistons and
valves
in good order.
So, from my experience, I feel the 550/560cc
injectors are the best choice for
those people running 13G's, and those with
15G's who aren't running over
1.35-1.4 bar (or 1.3bar in these cold
temps). And to run those kind of boost
levels, race gas IS necessary -
which many of us don't have access to anyway
(unless we are weekly track
goers). However, if you have 15G's and are
involved in the drag racing
scene, where the extra 10hp from 1.3 to 1.5bar
will shave off that extra
tenth, then 720cc injectors are a good idea.

Team3S: Letter to Federal Trade Commission (long)
Here is a copy of a
letter I sent to the Federal Trade Commission regarding
the
Chrysler-Mitsubishi-Getrag arrangement.
- -Bob
-
------------------------------------------------------------------------
Dear
Ladies and Gentlemen,
I would like to make you aware of a business
practice that strongly smells
of unfair price-fixing and collusion between
Mitsubishi Motors of Japan and
Getrag Gears of Germany. I am only one
of the few thousand consumers are
has been affected by this
arrangement.
In the late 1980s, Mitsubishi Motors of Japan designed a new
grand touring
car that later became to be known in the U.S. as the
3000GT. In Japan, it
is (and always has been) called the GTO.
There are 3 versions of the U.S.
models: "Base", "SL" and "VR-4".
In an attempt to generate additional
revenue, Mitsubishi allowed Chrysler
corporation to market and sell a
similar line of vehicles under the name of
"Stealth". The Stealth product
line consisted of "Base", "ES" and "Twin
Turbo". The top of the line
models, the VR-4 and Stealth Twin
Turbo had an average list price of around
$42,000 and $37,000
respectively.
The VR-4 and Stealth Twin Turbo models feature full time
all-wheel-drive.
Starting in 1994, they were sold with 6-speed transmissions
rather than the
5-speeds that came with model years 1991 through
1993. Mitsubishi arranged
with Getrag, a company with
manufacturing facilities in Germany and the U.S.
as well as Japan, to produce
the 5- and 6-speed transaxle (transmission) and
transfer case for these
vehicles. Getrag is the sole producer of the
transaxles and transfer
cases. Mitsubishi has also mandated (by contract)
with Getrag that it
may not sell replacement parts to Mitsubishi's parts
depots or to any third
parties. Therefore, if even the smallest part, such
as a ten-dollar
synchronizer ring, wears out inside of the transmission, the
owner is
required to replace the entire transmission. Since the
transmission can
only be purchased from a Mitsubishi or Chrysler dealership,
the consumer is
forced to pay an inflated price between $3500 and $4500
excluding labor
unless the car is under factory warranty. Transmissions
replaced under
warranty must be sent back to Getrag for re-manufacture.
Those
re-manufactured transmissions are then sold back to Mitsubishi and
Chrysler
dealerships who make them available to out-of-warranty customers
for $3500 to
$4500.
Getrag Gears of America has long been aware of the situation of
cars coming
out of warranty and needing replacement parts and, although they
would like
to help owners, have been unable to do so without breaching their
contract
with Mitsubishi. They have also indicated that they ceased
production of
transmissions for Mitsubishi and that the only transmissions
for these
vehicles that are available on the market are the re-manufactured
units that
are being recycled from Mitsubishi and Chrysler dealerships.
Worse yet, it
is rumored that Mitsubishi has ended production of the 3000GT
as of model
year 1999. Chrysler's last model year for the Stealth line
was 1995.
Consumers who have attempted to remedy this problem by directly
contacting
Mitsubishi Motors Corporation in Japan have been rebuffed on more
than one
occasion. I implore you to look at the contract between
Mitsubishi Motors
of Japan and Getrag Gears of North America to confirm that
an unfair
business practice truly does exist and that several thousand
consumers will
eventually be effected when all of the cars go out of
warranty. .
Mitsubishi Motors should be held accountable to their customers,
many who
are now making payments on an expensive vehicle that they can't
drive.
Thank you for your attention to this problem. I would also
be interested to
know whether if you decide not to pursue the issue so I can
begin exploring
alternative ways to resolve it. If I can can be of
further assistance, I
can be reached almost any time of the day or night
(561) 883-2669.
Sincerely yours,
Robert A. Fontana

Hey Guys,
As previously

it is not
consistant, is not because of the battery(new york and cold!),
and goes away
when i restart the car.if that does not help i turn the
key on and off 10

days
Any

===============================
Marc...
Although
I've never had this problem (ABS light coming on) with my VR4, I
experienced
it with my Talon TSI with some regularity. As you indicate, it
normally went
away by turning off the engine and restarting. In fact, this
was the
recommended procedure in the owners manual. The symptom normally
occurred
during cold and/or wet weather. When exploring this issue, I found
the
sensors are very sensitive and this is to be "expected". A hassle, but
no one
ever fixed it (and I owned the Talon for five years).
Looking
forward...Chris

In my case, the resonance occurs when I _lift off_ of the
throttle
slightly when cruising at 7 psi/.5 bar or so. The sound is
easily
reproduced but that hasn't gotten me any closer to a solution.
Also,
the resonance began as soon as the FIPK was installed - never
happened
once before then. Chris' Blitz BOV is on its way to me so I
will let
the group know if it makes any difference. In Errin's case it
seemed to
eliminate the problem, which is interesting since the stock BOV is
still
in the loop and the resonance occurs at boost pressures where the
Blitz
will not be venting. If the HOOT persists with the Blitz
installed, I
will take the stock BOV out of the loop and try Roger's first
generation
HKS SBOV when I join him and Mike Chapleski for dyno testing
in
Switzerland in a few weeks.
