Subject: RE: Team3S:
Rear end shutter under heavye boost/High RPMS
Could be early stages of
transfer case failure. Could be worn driveshaft
carrier bearings or an
out-of-balance driveshaft. I mention these two first
because they are
both potential problem areas with this car. I replaced the
driveshaft
on my '94 VR4 as it was on the way out. Although I did not
experience
any shuddering it would eventually have caused something similar.
It is
possible that the rear-end could cause this shuddering. The
viscous
coupling in the diffs could be shot.
It could also be
imbalanced or bent wheels, poor alignment, or any number of
suspension
related ills.
That doesn't help much toward resolving the problem but
hopefully gives you
areas to investigate.

Eric..this occurred with my TT on only one occasion, and I found the
fix was real simple
after describing it here (simple usually). My wife had
used it before me and topped it
up with REGULAR. I dumped in some octane
boost and the problem was solved. Hope your
problem is as simple...ie shitty
gas!!

Re: Team3S: RE: injector cleaners
What I did last year when I had the top
end torn down is send my injectors
to RC Engineering and had then cleaned and
balanced. They did before and
after flow tests on each injector, and
two of them were pretty bad off in
the before column. Everything
was pretty well balanced (flow rates) when
they got done. Worth
the $ I thought.

Eric, have you checked the fluid in
the rear diff and or transfer case? I hope
its this easy to fix. Even if the
fluid level is correct, the wrong type of
fluid can also do strange things to
the AWD system.

Hey
all,
I'm trying to debug my sister's new VR-4, a replacement
for her totaled
92 ES, (1991, Red with 49k) for some "Post sales"
warranty work.
If you could decipher the title, you may know
what I am talking about,
but I'll do my best to describe
it.
When you accelerate hard, the backend seems to shimmy @
about 4500RPMS
in first through second. This occurs if you start from
a stop, or, if
you are moving and "get on it".
It
is not on one side of the car or the other, and sometimes feels like
it is coming from the center of the
car.
AWD?
Rear Dif?
Thoughts, ideas,
concepts?
experiences?
Thanks.
Eric

Team3S: Problems / rebuild page up and running
Hi friends,
To
anyone who's interested. I've just uploaded my "Problems/rebuild" page to
my
homestead at GeoCities (urgh). You can find it under the first topic on
my
3000GT page :
http://www.geocities.com/MotorCity/Speedway/9589/3000gt.html
Any
comments, suggestions upon my findings are very welcome.
Take
care,

RE: Team3S: BOV situation
I have a question: Under load/boost I
hear a hissing sound. It's not
turbo spool and I don't have any leaks.
The only thing I can thing of is..
1. I can hear the air coming out of the
wastegates (don't think so but
worth a shot)
2. My bov is not
ajusted tight enough.
I have 13c turbos, ATR Downpipe/exhaust, Blitz DSBC
and a Greddy BOV (the
purple one can't remeber if it's type r or s)
When I installed the bov all
I did was unscrew the adjustment and tightend it
until it just started to
grab the theads and made it hard to turn by hand (no
allen wrench used).
It closes at idel and blows off fine, just wondering if
my boost would come
in harder if it where tighter.

Re installing a SAVC-R
Big thanks to Jim in Germany,
Barry in Scottsdale, and Errin in Seattle,
for the help they afforded me in
my recent Super Apexi Boost Controller
installation. Without Barry King's
advise on the plumbing and wiring I'd
still be inching along. Jim Matthews
provided excellent setup
instructions which I compared with what Barry
calls the Apexi ESP
instructions, which I cross referenced also with Barry's
advice on the
same..then made up my own mind ( See below). Errin
Humphrey did a
middle of the night check on the color codes of some wires for
me in his
car, so I could get on with reconnecting a couple of wires which
were
inadvertently pulled loose...and which Barry also double checked for
me
in his car in the midst of his infirminty. The whole thing went
great.
Even Chien at Nexus offered to help with advise, which is a
rare
attribute these days, and particularly in this case, as most of you
know
I did not purchase there (group purchase). One does not see that sort
of
thing often... great guy...nor the first rate help I received
from
these Team 3S members across the planet.
Now if I had chosen
Blitz instead of Apexi, I'd likely be mentioning
Switzerland and lauding
Roger for his installation assistance...but you
all know how knowledgeable he
is if you have followed any of his posts
here. Then there's Chris if I hadn't
picked either Apexi or Blitz......
So here is what was offered as
advise:
Roger at his rebuild site indicates that over 1.05 bar could be
of a
disadvantage (read possibly a rebuild).
Jim echos this notion and
advises 1.05 for a max setting in second mode
and 1 bar in the first mode. He
advises 70% BADC, which Apexi also notes
in their instructions.
Barry
advises more of a conservative setting at 62-64% BADC and believes
70% is
possibly overboosting. He also indicates 1 bar, and 1.05-1.1 bar
for the
second setting, so advise for bar settings is pretty
much
unanymous.
It's interesting that with the number of rebuilds and
Roger's just
updated site on his engine findings with possible causes and
solutions,
is giving rise to more conservative suggestions for settings. Any
other
advise re settings, appreciated...currently set at the
most
conservative.

Great page RG, with lots of information.
Terrific pictures too, but here's
where I stick my 2HP in... If you
"optimize" the same photos at about 70%
quality (medium) instead of 94%
quality (high) your page(s) wil load 3 times
faster (pictures are the same
size, but file sizes are 1/3 as large)!!!
Anyone on the list that would like
me to send them my "Imaging Tips" post I
did a year ago for some of the other
S/3k guys, please contact me privately.
Nice job,
Roger...!
