I'll keep that in mind when i get prices on the Carbon Fibre pads (i

My thought's exactly. _BUT_ the questions is how _much_ is the stock
clutch compared to an aftermarket clutch and what kind of/if any
difference is there in weight?

I've heard the slotted ones cause more wear'n'tear than crossdrilled but
personally, i don't think the slotted look as good.

Agreed. Although it would be a cheap way to go, I'm not planning on
using my next exhaust as a temp (like Rich L.) cause (a) I don't have
open access to a VR-4 exhaust and (b) i'd rather have a muffler shop
price me and give me what _I_ want.

The HKS I like only cause of the exhaust tips (I'm for the big but
skinny <when comparing outer diameter to inner diameter of the tip
itself> unlike the ones on Parham's Sabetazm's car. His look great, but
they remind me of the Neons/Honda's around here.. <sorry Parham>)

Elaborate on "SS."

Thanks for all the insight.

Go to discount auto parts, and find the resonated dual chrome tips that
are in boxes. The chrome ends look very similar, and to the uninitiated,
just like stock, so you have the low key effect. not only that, but as
on my R/T, I had to cut the back bumper notch out, and because i didn't
paint the inner "lip" of the cutout, the dual tips were the only ones
that filled that notch up.

Ok, as for the stock clutch, I just replaced mine and went through that
decision process, so here's the numbers I got (my dealer here doesn't give a
3SI discount)


Stock clutch:
Disc $70
Pressure Plate $70
t/o bearing $20
total.............$160

Centerforce DF
$429  (@nexus)

Labor to install new clutch:
$550 (aprox. at dealer)

The general consensus among the lists (Team3S, starnet, dragnet) seemed to
be that if you're staying under 250HP, then you really don't need anything
more than the stock clutch, and if you get an aftermarket one, you'd be
making it more "binary" and thus more of a pain in the a#$ to drive normally
(when you don't want to give your passenger - or God forbid a date:) -
whiplash.  Hehe, hey baby, check this out- I can go from 0 to whiplash in

And on the side note:  You're overclocking your CPU!  Don't you know that
overclocking is the invention of SATAN?  Bad! Bad! Bad!   No, just kidding:)
Be careful on water-cooling your CPU, though- Although I'm sure you know to
take extra precautions to contain the cooling water, but you also have to be
concerned with condensation (that can really trash a CPU).  Also, even with
cooling the case (BTW, take the side panel of a Supermicro SC750A case off
and sit a 14" mainframe fan beside the tower to cool it:) and cooling the
CPU's heatsink, you'll only be operating with the lower end of the
temperature differential at room temp, at best.  To get the insane speeds
you see at trade shows (and like 550 out of a 300), you need a refrigeration
unit.  And secondly, the temperature you really need to be concerned about
is the junction temperature of the transistors on the CPU die, not the temp
on the case or heatsink.  I don't know where AMD takes their core
temperature readings (if they even have a temp monitor??), but watch the
core temp when overclocking!


Here's my overclocking experience:

   Processor (rated speed)

1) Pentium 100 ( 66 MHz FSB, 1.5 multiplier = 100MHz core) PASS
   Pentium 100 ( 66 MHz FSB, 2.0 multiplier = 133MHz core) FAIL

3) Pentium 166 MMX   ( 66 MHz FSB, 2.5 multiplier = 166MHz core) PASS
   Pentium 166 MMX ( 66 MHz FSB, 3.0 multiplier = 200MHz core) FAIL

   Pentium 200 MMX  ( 66 MHz FSB, 3.5 multiplier = 233MHz core) FAIL
   Pentium 200 MMX  ( 75 MHz FSB, 3.0 multiplier = 225MHz core) PASS
5) Pentium II 266 ( 66 MHz FSB, 4.0 multiplier = 266MHz core)
PASS
   Pentium II 266 ( 66 MHz FSB, 4.5 multiplier = 300MHz core)
PASS
   Pentium II 266 ( 66 MHz FSB, 5.0 multiplier = 333MHz core)

6) Pentium II 400 (100 MHz FSB, 4.0 multiplier = 400MHz core)
PASS
   Pentium II 400 (100 MHz FSB, 4.5 multiplier = 450MHz core)
FAIL
7) Pentium II XEON 400 (100 MHz FSB, 4.0 multiplier = 400MHz core) PASS
   Pentium II XEON 400 (100 MHz FSB, 4.5 multiplier = 450MHz core) FAIL

   Pentium II XEON 400 (100 MHz FSB, 5.0 multiplier = 500MHz core) FAIL

My definition of PASS is that the system runs reliably for at least a month.
FAIL means it either wouldn't boot or it had unexpected crashes or BSODs.
Also, my cooling consisted of a huge tower case and somewhere between 4 and
10 fans as necessary.

I think I found it.  Please let me know if these are incorrect:

DIN PS = kW     * 1.36
SAE HP = DIN PS * 1.123
lb-ft  = Nm     *  .738

Subject: Team3S: Front VR-4 calipers

O.K. I decided to go ahead and get them from Autozone. They had them for
$91 total, including the core charge. They look like a quality rebuild, and
they are the 4 piston models (which i doubted when i placed the order).
They also have the standard Autozone lifetime warranty. So now i have 2
leaking calipers to use as cores when i get to that point on my 240Z
project. ; )  So, if anybody needs front calipers for thier VR-4, (and you
are poor like me) Autozone is the place to get them. FYI; the next price
bracket was $129, from the dealer.

Subject: Team3S: Timing belt slippage

Replaced my timing belt and tensioner last weekend after noticing that the
belt was extremely loose.  The cuts on my hands haven't even healed yet and
today when I checked the new belt, it's loose too!

We used the "special tool" used to push the tensioner pulley against the
belt (10 Nm, I think), tightened the center bolt (42 ft-lbs, I think) and
rotated the crank 4 times using the other (hunk-o-metal) special tool.
Waited 5 or 10 minutes and checked the autotensioner clearance.  Within spec
(3.8-4.5MM, I think).  Checked all the timing marks and they were perfect.

As a sidebar, we did notice that the book calls for turning the crank one
tooth counterclockwise from TDC to, as Mitsubishi puts it, "facilitate the
installation of the belt."  When we did it that way, we ended up being a
tooth off every time.  After 3 or 4 attempts at this, we put the crank at
TDC and sure enough, it ended up being right on.  All 5 marks lined up.

Now, before you say "it must be the tensioner" remember that it's only a
week old and we tested it before using it.

Questions:

1) My understanding of the tensioner, high-tech as it is, is that the
tensioning rod should resist being pushed in.  The same rod, however, should
pop out if there's no tension on it.  This could be important.  I noticed
that both the old and new tensioner rods popped out with little provocation.
Is this right?

2) Both times that the timing belt came loose occured after plenty of
driving with the "street" VPC EPROM.  The timing belt showed no sign of
looseness just before switching to the "race" EPROM which has some serious
deceleration which is not present in the street version.  The amount of
deceleration is dependent on my "Response" setting.  The more I turn the
knob up, the more acceleration I get on the upside but the more deceleration
I get on the downside of the RPM curve.  This phenomena is documented by
HKS.  Is it possible that such rapid deceleration is causing the tensioner
pulley center bolt to come loose?

3) Other than a bad tensioner (which I refuse to believe), has anyone ever
had a timing belt come untensioned by a bolt backing out?

=====================================
Richard...

I'm not interested in a debate, but I'm willing to make an observation:

Advertising can be misleading and may be intentionally so on occasion. I
haven't seen the specific K&N advertisement to which you refer, but most
product ads are purposefully vague, stating something like: "gains of up to
xxx hp". If you stop to consider mathematics and the English language, their
claim is likely to be true. If, for example, K&N claimed "up to a 15hp
gain", your measured 2hp gain is indeed within the natural number confines
of zero and fifteen. The same would be true if they said "up to a 10% hp
increase", which would be true from zero to 20hp on a 200hp engine. The only
way it could be false is if their product restricted air flow (over the
factory unit) and caused a hp decrease.

In your example of spark plug wires, it could be said that they "allow" hp
increases. A 22awg wire will not carry the voltage or amperage required to
produce the spark needed to effectively ignite gasoline in an internal
combustion engine. A set of 8.5mm Magnecore wires would definitely allow a
hp increase over a 22awg wire. Wires don't create horsepower, neither does
an intake, or an exhaust. However, the optimal combination of these (and
many other) factors is what making modifications to a factory system is all
about.

I believe I understand what you're attempting to say, and it's been said
many times before:

"Let the buyer beware"

BTW...several of us (I don't know about "a lot") are measuring performance
increases based on 1/4 mile times, not on advertisements. It's one of the
reasons that we're eagerly awaiting the results from the European trio who
just dyno'd their cars (we don't have AWD dynos here in the States, at least
none in Oregon).

Looking forward...Chris

Roger, I don't quite follow what you are saying.  Are you saying that you
~know~ that the compressor in the Japanese GTO's is a 13G?  That was
my original question:  Is the compressor wheel in the Japanese GTO's a
9B (like U.S.) or a 13G (like Europe)?  In either case, TD04 should be
on the housing, since a 13G still utilizes a TD04 housing.  I think you know
this.  The only thing is that the Japanese magazines don't list the compressor
size, only that the turbos are TD04, and I don't know anyone in Japan
with a GTO.

Hello all,
First I would like to thank you for a great list.  Especially Roger G and
Errin H for their help with my new DSBC and custom exhaust.

Bob,
I replaced my timing belt and tensioner about 3 months ago.  I actually did
it again three times to see if I could get the slack out.  My original belt
was extremely loose too.  Are you noticing this looseness between the sets
of cams?

I had the same problem.  I redid mine three times after totally putting
everything back together and driving the car and then the next morning,
loose again.  So loose that I could pull up on it and the cam would slip a

I couldn't purchase the tool from the dealer so I made one out of a 2' piece
of 1/8"X1" steel and two small high grade bolts.

The new and the old tensioners seemed to act the same for me too.  Both
seemed to have the same amount of spring to them.  Very stiff.

Don't know anything about the affects of the EPROM.  Did you check to see if
your cam bolt was loose.  I believe there is an access hole in the cover to
look at this.  However, I don't think this is your problem.

If the bolt on the cam that tensioner gets loose then your belt will
defiantly become loose also.  Are you rotating the cam(with the special
tool) clockwise and then tightening the bolt?
BTW-I asked Brian at the GT Alley about loose timing belts and he said this
was normal.

My belt was coming loose because after you pull the pin(I used an allen
wrench) out of the tensioner the cams are spring loaded off of the valves in
a way where they want to turn to where it causes slack between them.
Therefore it causes the tensioner to go in farther.  When your belt is loose
you should try to see if you can get the pin back in.  When I took it apart
the last time I put a wrench on the cam closest to the front of the car and
one on the crankshaft pulley and turned them opposite from each other(cam
counter clockwise and crankshaft clockwise), to get rid of any slack, while
someone else used the tool and rotated the cam tensioner and tightened the
bolt on it.  We then pulled the pin out and tested it according to the
manual and the distance on the tensioner was within specs.  Drove the car
around and it was loose again.  This time you could barely wiggle it.  I
have been driving the car like this for about 10K and have had no problems.

Sames deal, only one reply to keep this thread short...

1st.  You don't have to generate horsepower to improve the performace of
your car. (Lose weight, reduce drag, etc.)
2nd. Simply by reducing response time, reducing turbo lag may not increase
HP, but it will win races.  I beleive K&N helps here, but who knows?
3rd.  You talk about Dyno #'s, problem is they're not comparible to any
other cars that have any different mods.  The # of HP gained with a K&N on
an otherwise stock car is not going to be the same as one that has "The
Works"
4th. If a tuneup can "Create" or at least "regain" horsepower, most people
who add new plug wires will see an improvement, not over stock, but over
current condition.  (I belive most people here use Magnecor and they go out
of their way to say they aren't increasing your HP, over and over again...)

Bob,

A certain amount of static belt deflection (ie, when the engine is not
running) is normal.  The cams at rest will tend to roll one way or the other
creating a certain amount of "looseness" depending upon where you are
detecting it and the direction the cams happened to come to rest in relation
to each other.

If the belt is flopping around though then I'd say there was a problem ;)


Regards,

Barry

Steve;

Don't know if anyone got back to you on your query...hopefully someone posted
privately. If that occurs, please note it here.

My educated guess is somewhat in synch with what you surmise...possibly a mixing
of numbers in reassembly. There's a 50% chance this is right. Mayhap we'll get an
educated  response now,  to educated guessing :-)

Good luck

Best

Darc

Bob,

I had an experience similar to yours after having my timing belt replaced at
57000 mi. Belt, tensioner, and water pump were replaced.  About 3000 mi. after
the replacement, I took the belt cover off to visually check the belt and
found it to be so loose that I could spin the water pump with my finger.  I
had the car towed down to the dealer that had done the work. 

They checked the car over and said that the belt was normal.  They explained
that, depending on the position of the valves when the engine stopped, the
force of the valve springs was great enough to rotate the inboard cams in
opposite directions and overcome the 40-60 lbs of belt tension.  This results
in slack in the belt between the cam pulleys  when it is at rest.  When the
engine is started, the valve spring tension is overcome and the timing belt is
uniformly tight.

They demonstrated by cranking the engine several times.  Sometimes the belt
was loose and sometimes it was tight between the inboard cam shaft pulleys
when the engine came to rest.

I was doubtful, but didn't have any better ideas, and I drove off.  I have
since put 8000 additional mi. on the car with no problems.  The "loose" belt
at rest seems to be a normal condition.

Darc,
First of all, Mikael unfortunately could not join us since Sweden is a
bit too far away.  He may be visiting Roger later this year and perhaps
they can run some sessions then.  This time it was Roger, Mike Chapleski
(Frankfurt, Ger.) and I who went.  We are still trying to verify our
conversion factors and rescale the charts for the three cars so that
they can be overlayed properly, but I think we will have something out
later this week.  For now, take a look at the last line in my signature
for a hint and at my Stealth web page for information on my particular
run.  Again, while the DIN PS and torque values are absolutely correct,
I am not 100% sure about the DIN PS to SAE HP conversion (I found the
factor on a web page and it seems correct for cars that have both values
listed), so that value might change.  Enjoy!
