4 gauge MAY be OK, I don't know, but if 100 feet of it has 0.33 ohms
resistance, then 100 feet is way too much.

With 100 amps of current, 0.33 ohms would drop 100 amps * 0.33 ohms
or 33 volts, and you only have 12 volts to start with.

You MIGHT be able to start the car with as little as 6 volts, but ideally,
I think
you'd want no more than a 2 volt drop over the wire (especially with all of
our
electronics and computers), leaving 10 volts or so to start.

So the maximum wire resistance you'd want would be 2 volts / 100 amps =
0.02 ohms .


If the resistance of 4 gauge is 0.33 ohms per 100 feet (is that what it is?),
then you'd want no more than 6 feet or so, 3 feet if you run both a negative
and a positive line.

So 4 gauge might be OK for jumper cables, but I have severe doubts about
using 100 feet of it, or worse 200 feet for both positive and negative.


I think the "moral" might be that to do this right, you'd want to absolutely
minimize cable length, and use the biggest, most expensive cable you can.

And don't forget about the weight of all that cable, nor about the power
that will be dissipated in the cable during starting. A 2 volt drop at
100 amps causes 200 watts of battery power to turn into heat. Not too
bad for quick starts, but watch our for burning wires if you ever have
to crank the engine a bunch.



I = E / R
E = I * R
R = E / I
P = E * I

Where I = current in amps, E = voltage in volts, R = resistance in ohms,
P = Power in watts.

While we're on the subject of electricity,

I have an aftermarket stereo in my car, and I'm getting alternator whine
as the RPM's increase.  There is no noise whatsoever when the engine is off.

I've been told I need a voltage regulator/filter of some sort.
Any ideas where I can find one, and how much?

Thanks in advance,

According to my charts, 12 gauge has .145 ohms/100 ft, and 4 gauge has .025
ohms/100 ft.
4 gauge is approximately .25 inch diameter and weighs .126 lbs/ft

You really shouldn't need more than about 30 feet of 4 gauge which would be
about .008 ohms and less
than a volt drop when cranking 100 Amps.  This assumes the ground can be
made locally to the battery
on the frame of the car.  The resistance of the car frame should be much
lower than any practical
wire gauge.

    You can try a filter but that may not really be the problem.  If you have
an external amp powering a sub woofer you may need to shorten the ground wire
on the amp.  Make sure it is connected to a strong ground to.  If that
doesn't work I would make sure you are using a good gauge wire for all of

Ken,

    And others.  I went through a "conversion" process where I changed my
stereo in my car to a later Infinity version stereo( I think it's from a
'93 or '94). (It actually worked!!!!)

    At any rate.  I came up with some crude drawings that show the signal
path and the pinouts on the back of the stereo.  Don't ask me any detailed
questions because it's been over two years since I've even driven my car,
longer since I did the stereo conversion.

    I'll have to scan these pages in and post them as .jpg files.  I'll try
to get this done tomorrow first thing.

Hope this helps,

I need some help please! 2,000 miles ago, the

one here in south america so I decide to take it off
and I continued using my car without any temperature
problem for the last 2,000 miles, but yesterday, the
temperature started to go higher and higher.
I checked the water level in the jar and in the
radiator and they are Ok. I also checked the radiator
fans and they are working right.
The water pump is not leaking.
Can you please tell me what can be causing this

173kW = 234 HP power
500Nm = 369 ft-lb torque

http://www.3si.org/member-home/jlucius/2-converters.htm

First, assuming those are peak values, those two numbers don't match
well - the wheel torque is way over stock *flywheel* torque yet HP is
typical for stock *wheel* power. But that aside, Roger Gerl's web
site, http://www.rtec.ch/ , has dyno charts with "coast-down"
driveline losses you could try using to estimate flywheel power and
torque.

Subject: Team3S: What are some symptoms of misfire?

*First let me apologize for the basic questions contained here*

What does it feel like when your plugs fail to fire correctly?  Could
it make the engine "skip" a little, but only under load?  Would it
feel a little like multiple split second hesitations?  Could it be
mistaken by someone who has never, *NEVER* had a slipping clutch as
cluth slip? 

I ask because I have been reading up on spark plug gap in the
archives and I think that the "mechanics" that rebuilt my heads and
claim to have replaced my plugs either 1) did not gap them properly
or 2) did not replace them at all and there's a greatly incredible
chance that the plugs are fouled.  Of course there's always then
chance that I need new wires, too.

After my engine rebuild and new clutch I started to feel what I
thought was clutch slip almost immediately under load.  Now, the more
I think about it, I am entertaining the possibility that it could be
bad wires or plugs making the engine stutter under load and I am
mis-reading it as clutch slip.  Is this possible, or do I need to
have my clutch looked at?  The car idles OK, but I think I may hear a
minute miss (I have very untrained ears).  Would a minute miss at
idle lead to choppy hesitation under quick acceleration (say like a
hard push in 3rd from 55 to 85)? 

Any help on this would be appreciated!  I'm almost 100% sure that
it's the plugs and / or wires, but I want to see what you guys have
to say before I get in to the whole plenum removal, plugs, and wires
ordeal this weekend coming. 

Add to the shopping cart:  2 Mitsubishi oil filters, 9 quarts of
Mobil 1 Synthetic, 3 bottles of BG Syncroshift, 6 NGK Plugs, 6
Performance wires (maybe Magnacore), and one plenum gasket.  ;)

It's going to be a busy weekend...

Subject: RE: Team3S: What are some symptoms of misfire?

If your problem is plugs, you will hear missing as you increase throttle
WITHOUT load, like with the car sitting in neutral.  If it's a "minute"
(little) miss at idle, you can still see if you disconnect each plug wire
individually and see if the engine sounds change.  That's a way to isolate a
dead plug/cylinder.

A slipping clutch causes an INCREASE in rpm under load, until the clutch
"catches" and then the rpm goes back to normal for that speed and gear.

I get the sneaking suspicion you have a FUEL problem - it sounds like your
fuel pump or injectors cannot keep up with high demand.  Have you ever
changed the fuel filter or run injector cleaner through the car?

The spark plugs come "factory-gapped".  You won't notice a hesitation
problem with not having the 0.034" gap until you are operating at both high
boost and high speed simultaneously.  Maybe that's what you describe as a
hard push from 55 to 85 in third.

"Misfire" is very different from "missing".  Missing means the cylinder
doesn't fire sometimes or all the time.  Misfire means the cylinder fires at
the wrong time in the four stroke cycle, like before reaching maximum
compression of the fuel air mixture, or during the exhaust cycle.  Misfire
is a symptom of incomplete combusion, timing problems, or ignition problems,
like shorts.

How many miles/years on your car?  Are these the wires that came with the
car?

Actually on a turbo car bad plugs/wires will show up far sooner under load
than not under load.  Your test works fine on naturally aspirated cars, but
on a turbo you need to see how it feels/sounds under load.

If that's the definition of misfire, then our cars continually misfire as
there are only three coil packs and six cylinders.  Each time a coil fires
it ignites one cylinder with mixture in it and one on the exhaust stroke
simply because it is simpler to have a useless spark than to set up six
individual coils.

The wires could be the original set.  I am not sure.  The car has 58K
on it.  The injectors very well could be dirty, as well.  I guess
while I have the plenum off I'll dig through my manual and figure out
how to clean them (I can smell the diesel fuel already).  Since I'm
fairly sure that once I pull the plenum the car will never run again
(I need to have a little faith in myself...) I might as well do as
much damage... um, repairs as possible. 

I just read a thread over on 3Si.org that sounded a lot like what is
happening to me (they called it a 'shudder' while boosting) and their
fix was to get properly gapped NGK plugs.

I'm sure the injectors would benefit from a good cleaning and I'll
look in to the fuel filter, too.  Besides, I need to get these minute
but extremely important tune up issues resolved before I start
raising the boost.

Now I know for sure that it is not clutch related and that it is an
engine maintenace issue that I need to resolve.  The RPMs never race
up when I get the hesitation.  Like I said, I've never felt clutch
slip (even after driving various manual cars for years) so I had no
idea what I was feeling.

Thanks to all that have offered advise.  A properly maintained VR4 is
a happy VR4.

Highly..highly..highly doubtful  Dirty injectors run oddly, they dont
miss.  Unless theyre totally shot..then they do it all the time.

What does diesel have to do with a proper cleaning and balancing at RC?
_Thats_ how you clean injectors.

Thanks, Matt!  I guess I shouldn't write about how to rebuild the carburetor
either!

>>> After my engine rebuild and new clutch I started to feel what I
thought was clutch slip almost immediately under load.  Now, the more I
think about it, I am entertaining the possibility that it could be bad
wires or plugs making the engine stutter under load and I am mis-reading
it as clutch slip.  Is this possible, or do I need to have my clutch
looked at...?<<<

Hey, Travis,

To eliminate whether or not your clutch is slipping, do this simple
test:

With the E-brake on, put the car in 2nd gear at idle, and s-l-o-w-l-y
let out the clutch pedal...

If the car stalls, the clutch is fine.

If the car sort of "jumps" a few times and then dies, the plate is
warped.

If the car keeps going with the clutch out fully, the clutch is
slipping, and needs 'serious' adjustment or replacement.

Best,

Forrest
