Subject: RE: Team3S: 3000GTs have a speed governor?

There is a limiter on the 3/S TT models.  It is not a hard limiter like say
a stock Supra TT.  The limiter kicks in after some speed (I seem to recall
150-155) and watches the rate of acceleration above that point.  If the
car's acceleration is below some delta the limiter kicks in.  This is why
some people can get 154-156 MPH tops and others have had them wound out to
180 mph without ECU modifications.  The more power you have the faster
you'll be able to go within the parameters of the soft limiter.

This was explained to me by someone who uses the TechTom ECU equipment.
G-Force uses it too so presumably they could remove this "feature".  Duh.
Just checked. Their web site indicates this.  =)

Did you get this mnod also Arty?

Hello,

    I have had my car up to 165 indicated mph, did not notice any governor,

from everything I've ever understood about our cars as far as speed
governors go, the limit is always denoted as "drag limited" which means
there is no electronic limiter, that the aerodynamic properties of our car
themselves limit our top end.  my .02

Hello Marc thanks for the interest.
Yes, there is a speed limiter between 160-165 MPH that is removed as
part of our upgrade.
Yes, please see the DEC. issue of Super Street magazine for a nice
pictorial of an ECU upgrade on a 3000GT, It just hit the stands this
week.
The data editing software is called Mighty Map ($1500.) and this would
allow you to do your own programming. For the complete listing of all
the address' for the 3000GT programs you will need to purchase the
registration ($500). To do real time program tuning and map tracing you
will need the MT-2000($6500.)(Mighty Map incl.). Lastly you will need a
ROM-BOARD($400) and a couple EPROM's.
Instead I would recommend our normal high performance upgrade for
$845.00 installed and ready to plug in.
Yes, the upgrade will work with any electronic boost control including
the EVC. Also the filter, exhaust and VPC.
No 100% cure for the misfire but good spark plugs tend to help.
No fact sheet available for download but you can check our web site at
www.g-force-engr.com for more info, we should have an upgraded FAQ soon.

Unfortunately no dealers near so you will have to go direct through us.
Your 3000 should be able to make 360-370 hp easy with exhaust, filter,
evc, and ecu.
That would take it through the 1/4 mi in approx. 13.6 or better @
106-108+MPH (14.2 @ 100-102 stock).
Don't hesitate to e-mail any additional questions or concerns.

S/3k Turbos have a "feedback loop" kind of limiter built into the ECU, and
Japanese GTOs have an additional limiter...
I don't think there are limiters on the S/3k base models--  no ECU mods on
my '94 Stealth NT, but I've been at 135 with an inch of pedal left.  I
slowed down because I only had V-rated tires...

snipHmmm...dunno. I have run out of road  in excess of 160mph, and had to cool
it...maybe I was just about to run into the strong headwind (read limiter) discussed
here, but it seemed the car was good for more and wasn't maxed out. This is the first I
have heard of it and took it to be bogus until this G force response. Has anyone hit

If you are going to use a freon charged evaporative cooler (air
conditioner), you may want to think about chilling the fuel line as
well.  I am not sure about the density change of gasoline with
temperature drop, but I have seen systems for cooling the fuel line to
deliver the densest (most) fuel possible to whatever injector you have.
This will also help avoid another problem with turbocharged/fuel
injected engines: vapor lock.

Subject: Team3S: dyno tests --- drivetrain loss [long]

  Just some observations on the recent round of dyno tests -- It seems that
a fairly consistent loss of 80 Kilowatts of drivetrain loss is being
reported. My question is where the hell does it GO!! 80 kW is a serious
amount of power that has to be dissipated as heat. Without the benefit of a
radiator.

  The biggest loss items excluding the tires are the transaxle and the
differential. Lots of gears, bearings, power redirection, fluids etc.. My
old thermodynamics classes taught me that dissipating,  say,  20 kW in a
chunk of metal the size of a transmission is not easily done. These devices
are not heavily finned nor are they directly in the air flow.

  To a lesser degree that also applies to the differential. It's smaller but
probably gets better air flow.

  The CV joints and hubs should have minimal losses [roller bearings and
ball bearings] plus if you feel the suspension after a run without using
brakes the components feel relatively cool [ few kW's dissipated ].

  Tires are probably a major loss item, lots of elastic deformation going
on. I know the tires get a substantial amount of heat buildup but I don't
have any feel for how much power they have to dissipate. BTY If they are a
major contributor to loss,  the effect wouldn't be as drastic on a two wheel
dyno. The two undriven wheels are not moving nor is their potential loss
taken into account.

While there's not much to be done to change these non-aerodynamic losses it
would be nice to know if the numbers are realistic.

  I also believe that wheel HP is the number we should care about. Power to
the roadway is what moves the car. Flywheel HP is feelgood HP --- good for
bragging rights but it don't win races.  : )

The fastest I ever ran was about 174mph with the EU 13G model. The
speedo was off the scale and pointed to about 300km/h. This means about
285km/h - 290km/h real speed. I was not able to take a pic as it was
just too scary ;-)

I have seen 165-170 mph on the meter. This was just after I "walked" away from a Corvette :) I gues he was limited to 155 mph or he just didn't have any more power. I felt that the car actually had more to give but it's very scary to drive that fast and the road feels very narrow at this speeds. The car actually feels stable but the noice from the sunroof is painfull. I would gladly pay 1000$ to get that stupid sunroof replaced with a solid roof. It's ugly and noicy, I hate it!

Regarding the limiter, Maybe there is  a limiter that lower the boost so it feels like the car don't have the power to go any faster. That explaines why we, that have disconnected the stock boost solenoid, can go faster that 155 mph.  Or maybe there isn't any limiter...  :)

Subject: Re: Team3S: dyno tests --- drivetrain loss [long]

I'm sure someone is working on a more scientific response, but i thought i
would throw in my 2 cents.
Iv'e never taken any thermodynamics courses, but i think power is being
dissipated physically, not thermally. It takes a lot of power to rotate all
the parts of a drivetrain, especially a 4 wheel drivetrain. Take for
instance if you had a 5hp electric motor with the shaft connected to a
series of gears and shafts. If you measured hp at the end of all this
stuff, it certianly wouldn't be 5hp, and i doubt if the gears and stuff
would be hot. I know it's a crude example, but i think it makes sense.

As far as the 80kw figure is concerned, it's basically a guess. What they
did (correct me if i'm wrong guys) is add up all the "advertised" HP
figures of the aftermarket parts, along with the factory hp numbers, and
used this as thier flywheel hp. Now we all know that manufacturers
advertise hp gains that even though the manufacturer saw the gain in a lab
setting, it's hard to get the same gains in real life. So, the 80kw
estimate is high, but it's probably fairly close.

You're right about the 2 wheel vs. 4 wheel dyno thing. 2 wheel dyno's
typically see about 15-25%, vs. 35% as in this case.

O.K. my 2 cents turned into 5 cents, so i'll stop now......

All,

Who has replaced their pistons with aftermarket units?  Which brand did you
go with?  I am in the process of deciding between J&E and Ross.  I am
leaning towards the Ross pistons.  BTW, for those of you that have done this
swap, are you running a stock replacement or a custom design?

Thanks
Matt

So why is there a loss... Simple, it is the loss of the parts rigging
together, like the tires on the street. This mechanical loss is
transfered into thermal energy than finally goes away to the ambient.
Drive the car for an hour and just touch the drive shaft ... it more
that just warm.

No, these are the figure we got from measuring the car on the dyno. The
cars where pulled up to the max and then the clutch pressed. The dyno
recognized this and measured the resistance on the rolls by taking up
the energy the e-motors created. 4 cars where dynoed and all showed
about the same loss. At my earlier session I got half the loss on a
different dyno and this makes me thinking.

I still think that this is somewhat too high so stay tuned for further
session this year :)

Hey Eric;

Was this a new vehicle at the time? Any chance it had been upgraded to an automatic? I
know, I  know, whatya mean "upgraded"...however an automatic might seem like a good deal
to some experiencing Getrag blues. Didn't know they made them, but then again, didn't

OK. i've heard so many different things about dino and synthetic oils, and
which ones are better to use where. I'd like this lists insight as to what
we NA people should be using. I've read that synthetic lasts longer and is
less prone to thermal breakdown. But on the DSM list, it's come up a couple
times that dino oils actually lubricate better at temperatures under 500
degrees. Now i'm sure turbo engines will probably see higher then that if
not in the cylinders, maybe in the turbos themselves?? As far as synthetics
lasting longer, we usually change the oil every 2.5k to 3k miles anyways.
Some people have even noticed the engine tick got louder when they switched
to synthetic oils. Basically, what i'm trying to say is, should i use dino
or synthetic in my NA if i'm going to be changing it regularly, every 2.5k
miles?

The person seling the car was the second owner, and did not know if the
Tranny had been swaped, or if it had come from the factory that way. He
knew very little about the car except that the automatics were very rare
in the TT class. I just didn't believe the ad so I had to take a look at
it.

Very nice car, and a totally different launch with a brakestand in stead
of dropping the clutch.

Some things that makes me think it was a factory automatic: Same setup
as the N/A autos, with the PWR button and the Over drive button
fuctioning.

Now my theory: I have had experiences with one time, or special order
setups from the factory, when my sister bought her 82 Monte Carlo TURBO,
to find out it was a Pre- Grand NAtional, special ordered by a high
volume Chevy dealer for his Son, one of only two ever made.

These AUTOMATIC TT 3S cars may fall into the same catagory, undocumeted
special cars with VINS that would match a 5 speed tranny, that
executives had made for them.

I have a couple of people digging, but probably won't find much.

Subject: RE: Team3S: Pistons

I replaced my stockers with J-E pistons.  It was basically the stock design
although the ring lands were about 4-5MM lower on the crown.  I also had
them made to fit a .75MM (.030") oversize bore.  I had the block honed to
.0345 oversize, so my cylinder-to-piston wall clearance is .0045.  Standard
value is .0008 to .0016.  J-E says to use .003.  I used TotalSeal rings (2nd
ring is "gapless") and Clevite-77 bearings.

As TotalSeal warned, there is some top end oil getting pulled past the valve
stem seals but only when the car sits at idle for more than a couple of
minutes.  When I tip the throttle, there's a pretty good-sized puff of blue
smoke along with a strong smell of unburnt fuel.

One person warned that J-E pistons were "slapmasters" but I have absolutely
no evidence of that.  I'm really happy with the way the car sounds and the
way it runs.

=========================================
Omar...

Yes, heat is an critical consideration with the turbos, not so critical with
the NA engines. The issue with "ticking" is the result (IMO) of the lower
viscosity most of us are using with the synthetics. I have a feeling we
might find the same symptom with dino oil, if we used a 5w on the low end.
Keep in mind, the "ticking" is "normal" with hydraulic lifters when they're
not fully "pumped". They tend not to empty out if you're using thicker oil,
hence no "ticking". I would be VERY concerned if this symptom didn't go away
above an idle, but it always does.

Bottom line, you'd find many opinions, the choice is yours. Either way,
you're doing the right thing by changing the oil frequently.

BTW...I was a faithful user of Valvoline 20w - 50w Racing Oil for many, many
years before I bought my first turbocharged engine. Never had a problem. I
think we should consider another factor...if we "babied" our cars, never
drove near redline, never drove them hard and hot, they would certainly last
a LOT longer. Longevity is a tradeoff we make for the sake of improved
performance. What I strive for is maximum performance with out completely
sacrificing longevity, but I expect things (like the clutch) to wear out
faster than they do on my daily driver. Nature of the Beast.

Hi Roger,

Have you talked to both parties to get their explanations of why each
measured radically different loss values?  Apparently, at least one
shop's measurements are full of errors.  I think it would be worthwhile
to get to the bottom of this.

Thanks for all the good info,

Not to the makers yet but I spoke with other shops about the typical loss they
found. An Audi S3 therefore had a loss around 20-25%. I'll definitely
investigate more when I'm back to Europe :)

Subject: RE: Team3S: Pistons

I had custom JE pistons made for my '94.  The engine is not back into the
car yet so how they stack up is yet to be determined, but they should be
fine.  The pistons are very similar to the excellent stock replacements JE
makes.

They weigh in at a little over 400 grams each IIRC and were all within an
amazingly narrow variance.  Stock compression (8:1) is retained, 93mm bore,
slightly deeper dish and slightly beefier squish area than the stock Mistus
and stock JE replacements.  In theory this should make them better able to
withstand a little more detonation.  I opted for Speed Pro rings.

The JE pistons are almost too pretty to put into an engine, but I imagine
any new forged piston would look that way to me after seeing the destroyed
stockers.

Subject: Team3S: Engine oil: turbo vs. lifter wear

Can anyone give an opinion as to the effects of engine oil on turbo vs. lifter
wear and any tradeoffs using one oil vs. another? I believe I saw a post
suggesting non-synthetic oil for N/A engines to keep the lifters happy since
N/A engines don't have the high temps the turbo engines do.

The valve lifters had all been replaced just before I bought my car and right
now the engine sounds great. My first oil change was with Mobil 1 synthetic
10W30 as per the wisdom and advice of my mentor and inspiration, Mr. Dave
Trent. I'll probably continue to use this oil as it is preferred by most of
the people operating turbo cars - presumably to keep the turbos healthy.

However, let's suppose for a moment that I am more concerned with keeping the
lifters healthy - even at the expense of reduced turbo life. After all, I may
want to upgrade to larger turbos at some point, anyway - and I'd be more
likely to try replacing a dead turbo myself (stock or otherwise) than
replacing lifters. Perhaps I can even compensate for favoring the lifters over
the turbos by giving the turbos a good, long cool-down after each drive. What
is my preferred oil in this case?
