Team3S: Motor Oil
What brands of motor oil do most of you on the list
use? I typically
use Mobil 1 Synthetic on the street and RedLine on the
track. Sometimes
I use Castrol Syntec (If Mobil 1 is
unavailable). However, I ran into a
guy who owns an Oil
Distributorship, and he was absolutely positive that
the best oil on the
market was Amsoil. He said it outperformed RedLine
in every test.
He said Mobil 1 isn’t really all synthetic, which is why
they
can’t print “100%” Synthetic on the bottle (They say
“Fully”
Synthetic). I was a bit surprised, since I’d
heard so much about
RedLine & Mobil 1, but then I realized that I
didn’t know of any
independent testing that actually showed which oil
was best. Is there a
site that shows an independent test comparing
Amsoil with RedLine &
Mobil 1?
This guy went on to say that Amsoil
oil filters were much better than
Mobil 1 filters as well – in both
flow capacity & filtration. He said
Mobil 1 filters remove
particles down to 20 microns, while Amsoil
filters remove particles under 5
microns. If that wasn’t enough, he
finally said that Amsoil
Air Filters outperformed K&N Air filters in
both air flow and
filtration.
After talking with him, I felt like I’d just been given
a snake oil
sales pitch. Is this stuff that good, or was he full of
it? And more
importantly, is there a site with independent test results
on this
stuff?

Im a redline guy street and track...tranny and LSD

The extended change intervals you can get because of the total
lack of
synthetic breakdown makes up for the cost.
Of course..being a
famimly friend of the Sr VP and Chief Chemist for
redline helps, but doesnt
affect my judgement..im just that much closer to
the facts.

Team3S: What's next?
We tested my suspension upgrades yesterday, and now
I'm not sure where to
go from here.
An instructor measured the tire
temps after a couple of hot laps (immediate
turn off the track, directly to
the pyrometer, no cool down at ALL!). The
tires read 190 deg inside and out,
and 185 in the center. The instructor
says that was absolutely dead-on
perfect, and I should be very happy,
because lots of guys agonize over
getting their tire temps to a 5-deg
spread and I got it the first time out
(pure luck, gang! Or maybe a good
suspension shop.). He says I could make
miniscule changes in the tire
pressure to get 190 all the way across, but
he'd leave it alone otherwise.
Observers say the car corners completely
flat.
I am wondering what to do next, if at all.
Here's the
situation: I run Eibach springs (550 front/315 rear) with Ground
Control
adjustable suspension and camber plates on stock struts. The car
has
been lowered 1.5 in. all the way around. It has Yoko A032R tires. I
run
1 deg negative camber, +0.15 toe, and maximum castor (+4.5 deg). We
tested on
a 0.7 mile/13 turn go kart track with about a 60 mph average
speed, top speed
of 70+, nice warm spring day, and ran 75 laps. We ran
about 40 laps before
checking tire temps.
I can still get some push and scrub the front
tires, but two instructors
tell me I am overdriving the tires when that
happens, and I should go a
little slower to go faster. There is no question
that *I* have to improve
to go faster (be smoother and more consistent), but
my question involve car
prep:
Is there anything else I can do to
improve the CAR'S cornering ability?
Sway bars? Chassis stiffeners?
Polyurethane bushings? Or do the tire
temperatures say that I am at the
optimum point now?
Mitsubishi lore says that the Eibachs will ruin my
stock struts very
quickly, because the stock shocks can't take the abuse from
the higher rate
springs. So, what kind of shocks should I go to next? GABs
seem to be the
strut of choice for Mitsus.
Another instructor said to
leave the furshlugginer suspension alone and
just get more seat time. He also
suggested I forgoe any horsepower mods
until I get used to the new
suspension. I'm still running a stock engine.
(I was kinda hoping that my
suspension mods were at an end, so I could kick
it up to 400 hp)
All
advice is welcome.

Re: Team3S: Idling Trouble
Joe,
Have you checked **every one** of
the items in the service
manual troubleshooting list for this problem? My 92
TT was
idling weird. I checked almost every item in the list, and
found
each component to be working fine (including everything
associated
with the TB). Then I reached the item I had left to
last because I didn't see
how it related because the car ran
fine otherwise. It was the crank angle
sensor, the CAS worked
fine but the timing was off. I fixed the timing and
idle is now
fine. I am not suggesting that the CAS is your problem, but
that
you should work methodically through the troubleshooting list.
Sorry
I cannot be of more specific help. Good luck.

I use a

How
exactly did you do the spacing? With washers, a spacer ring, or what?
You are
using Grade 8 longer wheel studs, right?
No problem with clearances on the
calipers, strut or fender?
I always thought spacers were a no-no, but I guess
it all depends on how
you do it.

About the only other

bumper. I have some pics of
this type of install on my web site.

Select 1995 Dodge Stealth on the index frame. About half way down
the

1/4" spacer ring on each wheel, with

Considering theres another .3" to make the

be shopping around a custom rotor with a

Spacers arent a nono, just not on stock studs..and a

race like that.
Added track in front increases
oversteer..or decreases push (depending how

Sure you can... On stock
turbos the boost goes down quickly enough where the stock injectors can mostly
keep up. If you were to upgrade turbos then there's no way you can do it
as the airflow is much too high with the higher boost/rpm combination. I
was able to do it as well until I bolted on the 15G's last weekend. If I
try to go above 15 psi now I hit fuel cut, so now I'm forced into the larger
injectors. Still trying to get my ARC-2 working.

Exactly.
That 18psi is a peak,
and occurs at about 4800 RPM. After that the boost
starts dropping
off. The stock 9B weenie turbo's can't push more than about
13psi past
6000rpm and falls to as low as 12psi at the red line. Basically
I make
the little guys blow as hard as they can for as long as they can.
I
didn't need additional fuel, because A/F is not the problem with the
boost
curve that I produce. 4500RPM,
WOT,
18psi-way-out-of-efficiency-teeny-weenie-turbo-syndrome produces a
different
problem...Detonation. That's what the water is there
for. :-) Works well,
so far, so good. Been doing it for
almost a year now.

I have the heads off and
I'm replacing the rear head because I think it's a
goner. I just want
to make sure that the problem of the tapping, knocking,
whatever noises from
the engine is not from the rod bearing. I don't think
it is since I
have fairly good compression (150k mile motor) and I found
lots of hard
carbon desposits in the rear cylinder bank, but I just want to
be completely
sure before I put everything back together. I have the heads
off, but I
don't want to take the oil pan off because I supposedly need to
remove the
transfer case assembly. Is that hard to do? I notice that
the
manual says there are only two bolts that need to be taken off.
Seems a
little too easy, there has to be more to it right?
Is there a
way to check for a bad rod bearing without taking the oil pan
off? Like
is it noticeable from the top of the piston if the rod bearing is
bad?
Extra play when I turn the crank? Am I just a wishful thinker?
heh.

Chris,
The
compression will tell you little about the condition of the rod
or main
bearings. I would suspect that until a rod bearing disintegrates
the
connecting rod or portions of the block you would likely not see any
drop in
compression. The transfer case is held on by 5 bolts on the
94+
models. I cannot speak to the pre-'94 models, but I would guess the
same is
true with those as well. It really is not that much of a hassle
to get it
off. If you hearing a knocking from the lower part of the
engine I would
suggest pulling the oil pan and investigating. Better to
waste a few hours
and give yourself a sound nights sleep after it's all back
together, then
push even one more revolution with a bad rod bearing.
Connecting rods
through the side of engine blocks do not make for good
performance. :-)

I'm thinking mine is
somehow defective. I can't get it to dither the A/F ratio at idle.
It is full rich all the time or the motor quits (or cycles RPM up/down while the
ISC tries to stabilize idle and keep the car running). I've adjusted
low/mid/high/accell all to various values with no positive results. I've
adjusted the TPS to read .450v at idle, no difference there. I've tried
the settings that a local person is using successfully on his car to no avail,
etc. I'm just hoping that they'll fix it under warranty as I've not yet
been able to make it work successfully at all. I have another set of
values to try from Matt at Dynamic Racing which I'll try out this weekend, but
I'm not feeling very optimistic about it at this point, and I really* need to
get my 550's on the car.

No, it

from the ARC upon the value it read from the MAF.

I thought I explained why this is and in a next run I will record
the data
on a flat road. Please understand that I can't do this in 4rd gear
as I'd
exceed our speed limit on our highways a lot ;-)

Do not shift ! My recorded data is like a run on the dyno. Choose
a flat
road and start at 1800 rpm WOT in 3rd gear up to 6000-7000 (210km/h at
7k)
You will see that boost climbs up and will indeed reach max boost
around
3200 or even a little earlier, depending on the controller and how the
low
end is handeled. In this situation, the discharge temperature and
the
efficiency of the turbo are on the bad islands pretty soon and the IC
have
to work overtime.
> The SAVC-R graph modes also always show a

> flat line from 3400-5100 RPM or so
Yes, this is the same
with a simulated 1/4 mile run, although I'm above 4800
in these cases but due
to the light overboost after shifting, the whole
bosot is a little higher.
Watch the resolution of the AVC-R2 and what's the
difference of two dots on
the display are. I think its pretty accurate for
what I have
seen.
> How accurate do you feel your graph is?
I took two
reference points, at 4k and 5k. Both are corresponding to the
calculation and
therefore the possible error is around 2-4% due to the
adjustability of the
ARC. But look at the graph again, the resolution is
high on the axis and
you'll note that I still have 13.4psi (0.94 kg/cm2) at
6000 rpm what I think
is not bad. And at 5100 boost is still 14.4psi (1.01
kg/cm2) compared to the
14.8psi (1.04 kg/cm2) max boost. What is the
measured boost at those rpm with
the AVC-R2 ?
Just record the same data on the AVC-R and I'm pretty
positive you'll find
somewhat same data. The diffenrence between 4000 and
5100 is only 2.7% and
is what I've seen on the two peak-holds of the Blitz
stuff (pressing reset
at the right moment. Of course my finger trigger is not
that accurate and
fast enough and therefore 2-4% offset is possible) and I
like to be on the
lower/safe side than on the too optimistic
side.

Of course me too but driving the car around
lately and watching the boost
gauges more than usually are proving the
results. Of course I will only
believe in data that is really measured from a
boost sensor and I hope to be
able to get the measuring device up and running
next week. Then I "simply"
have to put both data together and then
adjust the conversion factors for
the formula. As said, the data is NOT by
the injectors (I do also have a
combined boost, IDC% chart) but it is from
the air flow signal read by the
ECU. This signal determines how much fuel
must be given. Of ocurse, if I
change the ARC setting to richer, I'm
simulating more air flow. But the
trick is that the ARC is NOT rpm related
like an AFC or GCC as it is load
related. If I'd change the mixture by +2%
I'd see 2% higher air flow
reading. But the 2% are still the same if the car
is still under full load.
And I will then also see 2% more boost and with the
reference point I will
then have to reduce the factor by 2% to get the same
boost at the points as
measured. This compensates the change on the ARC and
again shows the same
curve. BTW, the air flow did only show an increase up to
6000 rpm. After
that it stayed constant, i.e. the consumption increase of the
engine and the
loss of the turbo where the same. I can't wait to see a curve
with larger
turbos as then the flow should still grow.
Yes, I also
gave me the same question after the curve has been drawn the
first time. It
wasn't just flat enough and I couldn't do anything against
the problem when
boost falls below 0 (vacuum). But the interesting area is
under WOT and full
load (i.e. 3rd or 4th gear). But I took several runs I
made and always got
the same results. Of course, the less resolution I took,
the flatter the
curve got.
As said, I'll do "real" measures, although the data
used to calculate boost
IS real, and I will compare the results. I just hope
that I'll be able to
record rpm too soon :)

Yes, typically super-rich condition.

The TPS sounds good but you definitely changed way too
much.
The simpliest method is to set L,M,H to 0 (middle) and A to 0 (to
the left).
I doubt the car starts so turn back mid until you can get it
running (maybe
with the help of the gas pedal). If it idles crappy, try to
adjust M until
each change will cause a worser idle.
If M is set, go
to low and try to enrich it until idle is fine. It will be
higher and when
you hit the gas it will die but this is to determine if
everything works
well.
If L is set, turn up A one click and it will go super rich again.
But now
simply turn back L (slowly, give teh ECU time to learn) until it
starts
sweeping.
With this, the car is drievable and H must only be
set for the high boost
behaviour.
Fine tuning is then with slowly
inceasing rpm from idle to 3000. Maybe here
you have to adjust M one click
more or less and to compensate with L. Goal
is to achieve a smooth behaviour
from idle up to 3k. It's possible that idle
is now off but this is what A is
for this purpose.
BTW, what ECU pin did you connect the Yellow wire
??
Hope this helps a little (well, I guess the guys who sold you the
stuff have
already explained this to you, did they
??)

Well, interestingly enough I got a
2" pipe plug. It is really just 2
pieces of metal with a rubbery
gasket in the middle and a stud with a wing
nut on top. Rather simple
idea, tighten the nut the pieces of metal close
together squashing the gasket
(washer thing). This causes it to get bigger
and seal up tight.
Air tight. In fact, when testing the top my friend and
I put a air hose
in the line coming out of the pump to see if the rest of
the washer bottle
was air tight. We regulated the line at 20 psi (since I
don't really
think I would put more than that in it) and viola, it held.
The interesting
thing is that we grabbed the wrong air line in the garage
and got one that
was unregulated. We put about 165 psi of pressure in that
tank.
It swelled like a balloon, but quickly shrunk back down. The good
news
is, no air leak :).
BTW, the 2" pipe plug gasket is too big.
We shrank mine down with a belt
sander. Very messy.
Tank works
great!
