Subject: Team3S: Re: OVERHEATING, prolbem!

I think it is normal.
When you make more hp, for longer time, the engine makes way more heat--about
2/3+ of the heat an internal combustion engine makes is WASTED in exhaust and
into the coolant=radiator has to release it.  Thus, it is natural for 5-10
minutes of 200-450hp running to make WAY more heat than 5-10 min at 60hp=cruising
70mph.
Did the car OVERHEAT=Boil Over?  THEN you have a problem.  Many cars are designed
to run hot, 210-220 degrees F; ours are designed cooler via thermostat, but you
are SUPPOSED to see some variation, and supposed to see it get hotter with high
HP for longer periods.

The thermostat is designed to START opening (sending coolant to radiator) at
170F;   at light loads, you might not much exceed 170, and the thermostat may be
open only a little.   It is FULLY open at only at 194F!
WITH HIGH HP use, you generate more heat; to dissipate this, the thermostat
senses it and STARTS OPENING MORE--until, by fully 24F LATER, it is finally fully
open, at 194F.  The needle reflects this 24 degree change by CLIMBING.  With
coolant mix AND the pressure of the cooling system (15psi?),  you shouldn't boil
the coolant until around 230-240 degrees.  The extra ~36-46 degrees between 194
and 230-240 is important, because as the delta T (temperature difference) between
the coolant and outside air temp (to which the radiator dissipates the heat)
provides more and more heat loss, as the temp climbs; so though thermostat is all
open by 194 degrees, you still are not maxxing out the cooling system by any
means, yet.

I sure wouldn't (and don't) worry about it myself.  If you boil over THEN worry,
and check to be sure your fans are coming on at appropriate times; radiator comes
on at 178-192 degrees; condenser fan comes on at 196-210 degrees F.

I agree with Jack T.
I saw elevated temperatures three weeks ago when we were running at the
Marshalltown Go Kart track. I was running in 2nd gear, maintaining a 55 mph
average around the 13-turn track, accelerating from 30 mph in tight turns
to about 75 mph on the short straights continuously for 15-20 minutes at a
time. It didn't boil over, but the temps started moving high up the gauge
- -- enough for me to pull off the track and let 'er cool down. I guess if
you ran any car flat out for 10 miles in second gear it might heat up too.

BTW, it looks like we might be running at Heartland Park in Topeka on July
22 with the BMW club. Any body else going? I haven't gotten my confirmation
yet, but it looks good.

Subject: Team3S: RPS Clutch Situation Getting Better!

RE:  RPS clutch situation

To confirm what has been recounted by somebody else, I spoke with Rob
Smith at RPS.   He confirms that the independent company they've used to
do quality control/testing of their products has been testing the
3000GTVR4/Stealth TT (and some Acuras etc) has been testing the pressure
plate clamp load improperly; so, our pressure plates have been set up
"over center" so they are on the DOWNSIDE of clamping force, rather than
the UPSIDE--it is like the clutch is being depressed a little just
sitting there, even though you AREN'T pressing on the pedal.  This loses
about 500 lbs of clamping force, and makes the setup have about 21% less
torque capacity than it could have.  They are now in-house testing, and
discovered the error; so can now give us true 2900 lb pressure plates,
which with the carbon + ceramic 6 puck disc, should hold about 580
ft-lbs of torque!

My car HAD the low-clamp 2400lb pressure plate, and the full-carbon (not
half-ceramic, which helps because of faster breakin etc). so I am going
to install the stronger pressure plate and better disc setup.  I hope it
works...RPS and ACT are both planning a dedicated, thicker pressure
plate spring to give more pressure yet (Supras have 3600 lbs so they
don't slip!) but that is not yet available.

Mueller "Redhead" twin disc is an 8.5" dual disc (ours is ~10" stock)
but uses sintered iron friction material, which can be harsh/juddery
engagement, and tends to tear up steel.  Mueller told me they consider
it "race only", and I need to use it on the street, traffic jams etc. so
am not yet going to spring the $2000 for that deal.  The OS Giken
twindisc, is hard to get, nobody knows about how hard to get it
SERVICED, and also ~$2000.

I have to admire RPS, they DID science out the problem with the pressure
plates, have corrected that, and considering how relatively few of our
cars they are (compared to the HORDES of Hondas etc) are spending time
and brainpower on our situation.  Because they are used alot, problems
will show up for them alot (stands to reason)...but they keep learning
and thereby advancing OUR situation and so I'll stick with them.  I can
sure understand the frustration, I have it myself!

I have not had this overheating problem before, so I suspect it was just
all the 2nd-gear running. Before I put on Brad's Big Reds, I couldn't run
that many laps before feeling brake fade.

WW is perfectly safe with pure distilled water, and bout two bottles.

Lubes and chemically balances the system perfectly.

I run 100% water +2 bottles in all my street and race cars.

Should I live in an area that frezes..I drain then add a quart of A/F, then
flush it all clean in the spring again (because you should do this once a year
anyway)

NOTHING cools better than pure water, and WW aids in cavitation around the
cylinder walls.  A higher pressure cap also helps a lot as well.

Pure water is also much lighter than an A/F mix, and will pump easier at high
RPMs, and cavitate less in the water pump (which adds a huge amount of drag in
the fins).

Adding tap water is a bad thing to do..very ill advised.  Messes up your Ph and
mineral makeup of your cooling system a lot.

1] The electrolytic caps are usually easy to spot ---- are there only four or are
there four problem caps plus others.

2] Is the voltage and capitance marked on the devices and if not what are the values.

3] Can you detect the early stages of leakage or only after they fail.

Hi,

What should our oil temperature run in a VR4/TT?

Where should one locate an oil temp probe??

There was a lot of discussion in an open track list about Stang oil
temps.  The consensus was that oil temps should be below 250F and the
probe/sender installed in the oil pan.

After several overheating episodes and hopefully only having a blown
headgasket, I'm considering installing an oil temp gauge to perhaps
forewarn me of overheating in the future.

It sounds like you have air in the lines. This time instead of just adding
fluid, bleed out your lines to get the air out ... a clutch with air in it
usually has a "spongy" feel so if your car has the symptom you defenitely
need to bleed it.

Hi, I was looking at the instructions for the 60K tune up on the 3S web page
(http://www.stealth-3000gt.st/60k.htm), and I was just wondering if the
instructions and part numbers on this page are for earlier models or for
newer models. I think the part numbers  for 92-96 models are different from
other models and I have a '94 so I just want to make sure that I am buying
the right parts before I actually do this tune up.

Thanks in advance for your help!

Subject: Team3S: Pinging/knocking/detonation

Hi all,
I know this topic has been discussed ad nauseam and keeps coming
back every once in a while.. so it's my turn :-)  The catch is that this
time it's regarding a NA car.  My aftermarket radio died recently, so I've
had plenty of time to listen more closely to the noises my engine is making,
and I think it's pinging substantially more than I remember in the past.
I've always heard pinging in "you're in too high of a gear, dummy"
situations, but it seems to take less to get it to ping lately, and I'm a
bit concerned.  I usually try to make sure I'm in whatever gear will keep me
at or above 2000RPM when I'm cruising, and when I'm stompin' on it, I keep
it in the 3500RPM and up range.  The pinging I hear now is not that
noticeable above 3500RPM (although engine noise may be drowning it out), and
I don't hear it very much if the windows are up and the radio is on.
However I'm pretty sure it IS pinging.  To test things out, I tried driving
on some residential streets at 20-35mph.  If I shift to 3rd or 4th at 25mph,
it'll ping like the coins from the ashtray fund moved into my cylinders.  In
1st gear I really don't hear much of anything; and in 2nd I hear light
pinging in the 1000-3500RPM range if the throttle is more than about halfway
pressed.  I think I can pick out a slight pinging above 3500RPM, but it's
hard to hear with the wind/engine noise.  The car seems to be making decent
power - I had my friend in his stock base 3k follow me last week, and I was
pulling away from him when we were both at WOT in 2nd gear).
So I've had a couple of friends listen to it (they think it's
pinging as well), and I rode in my friend's 3000GT (basically same as mine)
and I can't hear the pinging in his car.  I'll probably ask him if I can
drive his car and listen just to make sure.
A couple things also make me think that there's something amiss
here:  my gas mileage has been down 3-4mpg for the last 2-3tanks and when I
hear the noise (that I think may be pinging), the car does seem to be
lacking some power.  I've been going to the same gas station (Chevron) at
the same location for the last year or so, so I don't think I got a bad tank
of gas.

So what do I do?  :)

I figure that I can assess whether it really is pinging by throwing a bottle
of the 104 octane booster stuff in with my next tank of gas and see if the
pinging goes away... good plan?  I've never used that stuff.

Assuming it is pinging, what should I check out?  This isn't a TT car, so
the boost isn't set too high.  Pinging/knock is caused by an excessively
lean condition, right?  So what would make my car run lean (other than
really bad stuff like a fried ECU/bad MAS/dead fuel pump)?

* K&N Filter?  The ECU should be able to compensate for
that, right?  I've had it for about a year now and I
did reset the ECU when I installed it.

* Resonator removal?  I don't see how....

* EGR valve stuck closed?  Could be, but it's not just
when I step off the throttle quickly.  It's during
smooth (low-RPM) acceleration, so the EGR valve
should be closed then anyway, right?

* Poor injector spray pattern?  It's only got 70,000mi
on it, and I cleaned it with BG 44K (supposedly
industrial strength FI cleaner from my dealer) last
year.   I only use Chevron/Texaco gas as well.

* Carbon build-up on tops of pistons?  Again, only
70,000mi on the car, so this shouldn't be an issue,
right?

* Spark plugs/wires?  Both replaced last summer with
60,000mi service.  I checked the gap on the plugs
myself as I took them out of the boxes.  I'll pull
the front bank plugs and have a look.  Anything
special I should be looking for?

* Something else I'm not thinking of?  :)

Thanks for reading my really long post and for your input!
