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!!

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.

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,
Roger

Subject: 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.

could be the carier bearing.  Mine did something kinda like that and had it
replaced under warrenty (after bitching alot).

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.

Try checking the carrier bearings on the drive shaft, u-joints, and rear

... and today I added the dyno-sheet to the problems page. It does show how
power was reduced due to the retarded timing and knock.

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...!
