I will take the quiz...shuffle, shuffle, grimace...

No other variables are noted other that those which are mentioned. This is
important. So assume, or consider absolute,  if you cannot assume, that
everything else is the same on the days noted other than what is mentioned.
Do not invent new criteria which have not been included in the question, or
as any student knows, you get a failing grade. That does not exempt me from
failing, but it certainly should help anyone who doesn't know this, who is
following me and doesn't need to make previous mistakes.

Now to the question.

There are many mods = z  (possibly z= w+x+y etc)

There are two different days with two different temperatures (a and b) with
a difference in temperature/factor of T

There are  two results (400 and 410)

a  gives a result of 400  (a = 400)

b+z  multiplied by T  gives a result of 410  (b+z (T)) = 410)

The difference between these two results is expalined by z  plus a factor of
whatever the temperature difference is T

Can you determine anything from this. Yes. There is a difference in
horsepower reading based upon temperature (T), and modifications (z). Since
z is a plural (modifications) more information should be given. If it was
one modification, and that modification was tested at the same temperature
as a,  then one can extrapolate. It is more than one modification, however,
and it is tested on a different day with a different temperature b. So one
cannot conclude anything regardless of the information given, other than to
answer wrong. The answer is wrong given inadequate information, without the
need to invent more information. Period.

I have not been able get the repair manuals for my '93 Stealth and had to
replace the water pump this past weekend.  I followed the instructions from
this site only to run into problems setting the tension on the single

Could anyone tell me how to set it?

Again, RPMs are another tangent to this discussion, one that would have been
better off leaving open till we finished the current discussion.  You have
also *not* proven that drivetrain loss does not increase as power increases.
I'm not saying that it does, but it seems feasable and I'll leave myself
open to that theory till that theory is *proven* wrong which can only be
done by an engine and chassis dyno session before mods and an engine and
chassis dyno session after mods.  This isn't going to happen so lets agree
to disagree and at least stop entering RPMs into the equation until we can
come to an agreement on the 'basics'.

What I was saying, Roger, is that by using the horsepower loss (shown in the
coasting test) you should be able to apply this to another car with a
similar drivetrain and get a "good general idea".  But, as you just proved
(asside from unknown variables) in the two PS examples shown the numbers
were not IDENTICAL and therefore it's nothing more than a "guess" or a "good
general idea" and has not been shown to be 100% accurate.  I'm pretty sure
that Mitsubishi probably spent the time and money engine dynoing it alone to
get the crank hp number, something no one on this list will likely do so we
try to come up with the closest guess we can.  Read it again Roger, I'm
supporting the coast test as the only possible option but it should not be
stated as 100% accurate.

I think the language barrier is hurting again Roger...  What I was stating
here was that the bottom line is what makes it to the ground, unless you're
trying to compare the losses measured between drivetrain mods.  If you're
not going to change your drivetrain, forget the loss.  Knowing that X amount
of power is lost between the crank and the ground isn't going to help you
until you modify the drivetrain.  Who cares about crank hp?  I don't.

Roger, put the crack pipe down.  I think it'd be kinda silly to say we lose
25hp more through OUR AWD system because Audi loses 25hp more through THEIR
AWD system.  The 'welded diff' method I mentioned is widely used in the DSM
scene by people who own dyno's, have made MANY more dyno runs than you have,
and have SERIOUS horsepower numbers and SERIOUS 1/4 mile numbers to back it
up.  Can you think of a better way to dyno an AWD car on a 2WD dyno?  Stop
being so argumentative.

At some point I'll just laugh at the person who gets outrun in the slower
car.  If this is a factor, learn to drive.  No one said it had to be a
straight line either.  Acceleration affects all facets of racing.  However,
there is no better comparison than 1/4 times.  The track is *always* 1/4
mile and if you must, you can *speculate* by correcting for altitude.

Jim, that's why several of us are trying to get people to stop talking about
percentage loss.  A percentage is nothing more than a comparison of two
given numbers.  for all practical purposes the loss number (measured in hp)
is going to change very little with an increase in power.  *If* it does
increase it'll be so small that the headache received trying to figure it
out isn't worth it.  Go with a static number.  And forget the RPM equation
for now.

Finally, someone who's actually measured crank and wheel horsepower.  Being
that you've already completed half the test, I'd be very interested to see
what your horsepower losses will be with more modifications.  I'd be willing
to bet that it will stay at or near 90hp, not 23%.

My front ECS struts are really bad and I bought a pair today.

I'm not ready to install them just yet but I have a question.

It seems that both of the pistons are collapsed and I can move them all the

Just wondering if this is normal.

It seems normal being that the boxes that they came in would not be able to

Can anyone confirm?

Most shocks are pressurized with an inert gas to reduce foaming

shock is shipped collapsed with a strap holding it in place.
If they're not gas shocks then they'll stay where you put em.

Ok, according to the service manual the specs for the front struts are:

Hydraulic, cylindrical double acting type.

I guess this means that they aren't gas charged, and if so then my shocks
are ok?

From: "cody" <overclck@starband.net>
Subject: RE: Re: Team3S: Misconceptions about drivetrain losses

I got one for everyone....  Since we are on this subject... 

As far as drivetrain loss goes...  (and this may actually explain
somethings, although someone else will have to do the math) 

Would it make sense that at a static RPM, say 6000 rpm, and in a certain
gear, that the transmission uses a certain amount of HP just to keep it
spinning, now what I propose is that measurement at a static RPM may
yield a percentage or static HP loss at that RPM.  What I theorize
though is that this loss may actually be different while under
acceleration.  Now, what someone (not me for sure) would have to figure
out, is HP loss at any given RPM instantaneously, because the whole
thing would be accelerating, and we actually have mass (the
transmission/drivetrain) that we are trying to accelerate as well.  This
is where a lightened driveshaft may come into play.

Sure, once we have an engine at constant 6K rpm, the transmission may
lose 75 hp on an AWD car, but what about instantaneous losses.  At a
static RPM, we are measuring things like bearing drag, tire scrub, and
friction at other places.  In an acceleration environment, we would also
be measuring the loss provided by how much the components weigh.

Anyone have solutions for both these situations???

This is not technically true - in practice it works, but it's not good
science.  Drivetrain loss is NOT constant at rpm.  Here's how a very
experience engine/car builder explained it to me - I hope I remember this
correctly:

Drivetrains, (for the sake of this discussion, this includes everything from
the crank output shaft back to the tires) experience something called the
'hydraulic' or 'shock' effect.  I'm sure everyone has tried to compress a
shock absorber with their hands, no matter how hard you push, it compresses
at the same rate (constant velocity).  With the shock absorber, if you apply
5lbs or 500lbs, it compresses at the same rate - roughly.   To varying
degrees, drivetrains experience this same effect, though obviously not as
dramatically as a shock absorber.  While the hydraulic effect is nearly 99.9%
effective at stabilizing compression/expansion velocities in a shock
absorber, it is about .5 to 1.5% effective in drivetrains - higher in auto
trannys with torque converters.  This means that high pressure on the top of
the piston (torque) does not translate into equally faster rotation of the
crank shaft - put another way; the piston is pushing 100% harder, but the
crank shaft is only moving 99% faster.

What does this mean in practice?  If you figure out all the math, (and I
have) what you start to notice is that the hydraulic effect tends to push the
torque curve down the rpm scale.  Peak torque may remain the same, but
because it is produced at lower rpm, peak HP (which is mathematically derived
from torque and rpm) is lower.  If you do the math you will see that this has
vast implication, and can quickly make your head spin.  Add to this the fact
that the 'hydraulic' effect varies at different rpms and you'll see why
professional race teams have very expensive software programs that calculate
this whole mess for them.

So here are the facts:
1. The % loss method of calculating crank HP is basically useless if you've
added power.  A 100 hp engine that loses 20 hp to the rear wheels will not
lose 200 hp if you bump the power up to 1000 hp.
2. Constant hp lose at rpm is not technically accurate, but it is as close as
you can get, just don't rely on it when you've added a lot of hp.
3. The coast-down method is close, but is still not accurate, especially when
large hp increases are used.

No need to test it, 18" wheels do rob hp.  From the tests I've seen it only
adds up to a few hp (2 - 4), and primarily has to do with the fact that 18"
wheels are heavier then 16" wheels.  You'll get more performance gains by
reducing the over-all diameter of your drive tires which effectively raises
the gear ratio (numerically).  Going from a 23" diameter tire to a 20" tire
is like changing the differential gear from 3.3 to 3.8 - you will notice a
big difference in 0-60 acceleration.

In my opinion CF drive shafts have no business on a street car.  They are
just too fragile, they aren't designed to stand up to everyday driving
hazards.

Sorry Roger/everyone those numbers were quoted at peak HP about 5700 rpms in
both cases.  Roger what you need to keep in mind here my MKIV has LW FW and
a CF DS so there was less rotational weight compared to a BPU+ with out
those mods hence more RWHP (more efficient driveline)

I purchased new ECS struts and shocks a few months ago (Tall. Mitsu,

Your similar experience suggests this is normal. The front struts I

It does require some effort to move them fully up or down but still fairly
easy.  Also at the top of the assembly, there are holes. At one point, I
noticed a drip of oil seep out of one of the holes as I was moving the
piston.  If it dead leak oil, there is no indication inside the cardboard
box or on the strut itself of any leakage.

Thanks for the responses,

From: Roger Gerl <roger.gerl@bluewin.ch>
Subject: RE: Re: Team3S: Drivetrain losses, dyno measurnment

Thanks all for your input on this topic, but it is really hard for me to
explain what I mean or better what I learned during the years having cars
on the dyno (and also seen some failing with big oil leaks and so on)

1. Quiz ... YOU ARE ALL WINNERS :-)

Ok here the initial question again :
 > Man measures 400hp to the ground on a cold day but then 410hp
 > after many mods on a hot day. Therefore the mod you have done
 > gave you 10hp to the ground. Right or wrong ?

Only saying the mod gave me 10hp is really wrong in this case. And I
minimized the variables as much a possible as Darc pointed out very
professional :-) Temperature, humidity, baro pressure are measured by the
dyno meter and entered to any equations. This is where the crank hp now
comes in play and its correction regarding the sensor values.

When the first dyno run (400hp to the ground) was done the crank hp was
determined by the coast down method. This hp then got corrected by DIN (or
SAE in the US) regarding the sensors inputs. Result : 460hp SAE hp (loss :
50hp)
On the second run (410hp to the ground) Result : 510hp SAE (loss : 60hp)

The real difference at the crank therefore is 50hp and not 10hp. This due
to the SAE correction that uses the ambient for proper calculation what
produces comparable values at the end. Depending on what year of SAE or DIN
correction the tranny is included as well. At DIN 70020 correction tranny
is not included in the calc and the resulting crank number is higher. In
SAE correction other factors are not included as well as the standard
changes are hard to track.

2. Why crank hp ?

I know that many of you don't care about crank hp and it is not my
intention to convince you but I like to explain why we need it for a real
tuning of the car. Under the line, it is much more important to know how
much hp the mod(s) really gave and this can only be done by correcting the
crank hp. To get corrected wheel hp you then deduct the loss from crank
what is what people are looking for. Here some dyno operators just enter a
value that they think the car has when no coast down is made. This is the
case on such 3 second pulls where the car is measured from 5000 to 6000 in
3rd gear. Not good without the ambient and coast down information but
results in 1050hp - This indeed is then more guessing than really measuring :-/

3. Why is rpm important ?

RPM is the base figure everything is measured against. hp calculated out of
torque, loss, knock, IDC... everything is based on what value is read at
what rpm. We only know the power to correct when we know at what rpm as
there is also one specific loss. With this we can also say a car makes peak
hp at 6000rpm. I fully agree that the integral over the power band is what
finally makes the car faster or the torque curve what finally accelerates
the car.

Some input from you guys :

No solution. Torque is needed to keep a rotational mass moving, more torque
is needed to accelerate the mass. But this torque is measured due to the
simulated full load on the wheels. But I also wonder how much  "shock"-loss
a tranny has when the clutch is dumped at 6800 ! When we want to test at a
specific rpm the dyno is locked in then at this rpm and boost or other
parameters can be changed having the car under full load. This is like
driving uphill with the throttle full open and the car keeps the same
speed. This is full load and needs the full torque the engine can deliver
to keep them rotating (the drums are electrical brakened while the
resistance is representing the torque then).

No I never dynoed an engine, although I was with them when they dynoed some
but never had one of mine on the crate.

I modified my engine and interestingly, power loss stayed the same even
with more than a year in between the dyno runs. The difference at the crank
was more than 40hp therefore no engine dyno necessary, as the drivetrain
loss curve is known for my car ! This gives me the ability to put any mod
onto the engine and immediatly see the results. They are then facts and not
opinions. Facts are provided on the dyno sheets posted on my site. Go and
learn. I say your opinion is leading you into the wrong direction. It is
your opinion that more engine power produces more stress to the tranny, but
why then showed my dyno sessions no difference in drivetrain loss while
engine power and torque increased a good amount ?? Therefore the additional
stress had no effect on the trannies power consumption.

Its BS when saying that I haven't double dynoed my own car when you know
nothing. You start flaming me by arguing that my results are an estimate
when I have dyno plots in my hand and you nothing ! I had about 16
different cars on the dyno and only about 7 were 3S cars and a back-to-back
test is often only possible after a cool down period of about 15-30 minutes
so we change the cars on the drums after each run.

Stop beeing flaming me and please reread the rules of the list.
Also try to show facts as well as I hope you understand what an example is.
I never ever wrote anything that the Audis loss is the same as ours....
Argh, I made an example and you put it the other way back in my
mouth....read and ask if you don't understand, please never interpret !
It's easier to write a short explanation than having to find the right
words when one shoots to another !


Through this thread I learned that still a lot of people are speaking of a
% power loss through the drivetrain what is not correct. When I had my
first car on the dyno (Le Baron 2.2 Turbo, about 10 years ago) I knew
nothing and learn over the years as well as I had to rethink some stuff
that was different than I thought. And on some stuff I was ignorant and
finally learned the hard way just because I was not interested in the facts.

This could be built up mildew and other funk inside the ducts.  The best
thing to do is start the car and get it up to operating temperature.  Then,
close all the windows and crank the heat up to full power.  Let the car sit
for about 10 minutes and hopefully this will dry out everything in the
ducts.

Simon -- I think this might be in the archives but hard to find since I
forget the keywords.  I thought it had something to do with the
condenser or something up behind the footwell that just goes bad (like
the filter or something).  Making your own mixture of some ammonia and
cleaner or a similar step to that (maybe there are commercial "A/C
system cleaners" that purge out some bad air).

I would say take it to the dealer but an A/C check is usually upwards of
$35 and more if they want to give you a new charge of coolant.

Yellow/Blue 13.47 V
Black/Red 0 V
Black 0 V (chassis ground)

It appears that Yellow/Blue is the fuel pump supply voltage.  I'm guessing
that Black/Blue is the fuel guage indication.  Only problem with this theory
is that Black/Blue on my bad car reads 8.76 V and the voltage didn't change
from nearly full to nearly empty.  The needle reads about 1/8 full when full
and reads E when the low warning sensor turns on.  I don't have access to
the good car any longer.

Any ideas before resorting to the dealer?

The fuel gauge and low warning sensor are both integral with and sold
with the fuel pump assembly (with pump) as one part for a list price
of $465.87 - MB698858 for turbo and MB698857 for the other models. If
it is the sending unit, then I bet it can be repaired. It looks to me
(from tearing these apart) that the float runs a "needle" across a
wound coil of wire - a "variable resistor" I think its called or
something like that. It is also possible that a wire is partly
shorted or grounded somewhere. Not sure how you would check the
gauge, but you can check the sender with a volt-ohm-meter. Start at
the sender and work forward.

My fuel guage has failed recently.  It indicates empty now when I
know there is over 1/2 tank.  I haven't checked the CAPS program yet
to see whether the fuel pump and guage sending unit are separate part
numbers.  Does anybody know?  The yellow light is not part of the
same electronics, right?  Any possibility that this would be an
electrical problem and not the fault of the sending unit?

Hey Jim just another random thought... (I have alot of these) but maybe the

Jim,

Look at the wires carefully again.

**Trace them out on the assembly.**

My earlier email below shows the wiring and the "devices" connected
on my '92 TT. Maybe they changed colors for your assembly? There is
no guessing though when you look at the assembly directly.

Jeff,
Seems strange to me that the pump supply voltage would be only 8.5, but I
didn't test it under load, just idle.  Thanks for pointing out the pictures
again.  I will try to remove the unit leaving the high pressure hose
attached since I cannot crack the nut  on the other end without fear of
destoying the hard line.  I'm sure my colors are not different than yours,
just my assumptions ;-)  I'm sure it will become clearer when I get the pump
removed.

There's an inline resistor in the power supply line at RPMs below 2500-3000
or so that drops the supply voltage to keep the pump quieter and supposedly
increase longevity.  8.5V is about right for that...  Rev up the car and it
should change to around 13V.

Reminder that physics does not take a vacation.  Front and rear strut
tower bars are meant to go side-to-side in their movement and not front
to back.  DO NOT attach a racing harness to a normal rear strut tower
bar as it will bend it like a straw if the harnesses are ever put to
use.

The only way this is possible is using a method like Jim Berry who has
an absolutely massive rear-strut tower bar that looks like a small
railroad crossing bridge with all sorts of beefy material and stiffness
(contact him for the details but I think it is a Road Race Engineering
bar of something).

Plus, no racing body ever allows harnesses to go over anything except a
rollbar or a harness bar.  Just be safe out there.


Yes it is possible to ourdrive the stock suspension but not for the
majority of people.

Yes those wheels are light but remember that they must withstand a 2-ton
sled hammering into a corner at 60 mph and up (88 feet per second) so
that is a lot of force at any one time.  Don't get the aluminum foil
ones but make sure they hold the car's weight.

And I remember watching Mr. Wizard when he hung a 5# weight from a bar
(solid)5 feet long suspended at its ends and then a 5# weight from a
pipe (hollow).  The bar bent in half and fell off the table but the pipe
was more rigid.

I can't help but think this is the same that a solid strut tower bar
will have vs. a hollow style.  I don't know about them since I have not
installed them but I just wanted to bring that up.

Thanks for describing the wheels too.  Those sound like a dream for us

No problem Darren, I knew what you were getting at :)  See at heart I am a
road racer unfortunately I lack the skills (right now) and the time to
aggressively pursue this.  But anytime I mod a car for myself or a friend I
go from the mentality of performance/function first then appearance. As for
they RH wheel I just looked at them and they do come in sizes as big as
18/10   :O  Now that is sweet unfortunately they only come in white or gold
[means after a road event you will b scrubbing them  clean :(  ]    The
reason above is why that rear bar was a custom piece,  an old friend made
for me.  He owed a big favor so I had him pay me back with that... he vowed
that if I ever asked him to make another (single piece not group run) he
would beat me to death with it.

Subject: Team3S: Lightweight Flywheels - Pros/Cons

Well, the tranny is out and is off to get rebuilt, it is time to deal
with an important issue - rotational inertia.

I had a Bozzspeed Chromalloy Flywheel on my car, which self-destructed
and whatnot, but we won't go into that.  I'm looking to replace it, and
here are the issues concerning a lightweight flywheel - please give your
feedback/thoughts!  Thanks!  BTW, I am considering going back to the
stock.. but read on.

Pros:
Better response - mainly mid/high-end
Faster acceleration - less mass = easier for engine to spin
Less vehicle mass - 11 pound savings for the TT
On certain ones - face is replaceable for <$100
Better heat dissipation - aluminum wheels will keep cooler, improving
clutch grip

Cons:
Low-rpm stall - it is much easier to stall from a start
Chatter - there are lots of complaints of this
Fuel economy loss - this is a claim I've seen a few times, it makes
sense to me (?)
Expensive - $400+
Vibrations - at low rpm, may people claim they vibrate.  I never go
slow, so I don't know

This is my list so far, please add yours, or comments!

And, I've only heard of 2 wheels being used on our cars - Bozzspeed and
Fidenza.  Anyone have experience with Mueller, Tilton, or others?

Thanks!

*not an advertisment*

Ive used the Mueller alum. flywheels with great luck.

Its an alum flywheel with a replacable carbon-steel friction surface.
Porterfield sells these.

I also personally have for sale a dual-plate Tilton Aluminum flywheel
W/'alum pressure plate.  The entire assemply incl. discs weighs 13lbs.
(Paid $1600, has never been used or installed)
