Ive never thought direct water application was anything but marginal, and
perhaps harmful.  Cool AIR (via water cooling/mist or not) is more
beneficial as all of your surfaces get to use it, not just the one point
where simple water flashes to steam.  Im concerned about heat cycling as
well.  Also, Im not convinced youre boiling fluid..if maintained properly.

A 2pc rotor will vastly outperform the VR4 style 1-pc.  No weak spot at
the hub attachment with all the heat cycling.  Its time to spend some
money Merritt.  And, unless you can confirm the actual vendor of those
rotors, you are being foolish comparing them against vendors that take a
great amount of care in selecting and changing casting vendors as quality
shifts within a given product line from a single vendor.  Theres a reason
the PF rotors went up $30/ea in cost, its from the feedback from this
list..that caused them to hold accountable vendor A, and move to a better
one.  Does the dealer do this..or care?

.034 is great. don't recommend to go under .030 unless you've got LOTS of
mods

   I just ordered new plugs for my car as they need to be replaced anyway
(have about 40,000 miles on them).  I'm going to try the NGK Coppers
assuming I can get the car working again.  In the meantime, I am going to
send my ECU back to foreign ecu repair and have them test the unit they
sent me in addition to testing my old ecu which I'm sending to them for
core exchange anyway.

   What should I gap the NGK coppers to?  Currently, I set the gap on my
double platinums to .034"  Should I go w/ the same on the Coppers?

- - They warp/wobble onyl when cold. Have you cold brakes on the track ?
- - The two piece never broke ... read again, the single piece design broke
not mine !

So I like them alot when they are hot an the right ones .. got it ?

Subject: Team3S: Cold Start Stumble

My 1991 VR-4 has developed a problem over the past several months: When
starting cold, it experiences a stumble, much like a carbureted car with
no choke.  The colder the temperature, the worse it is.  Coming from a
warm garage into a cold environment, it runs fine, but if it has been
parked in cold ambient (anything below ~50° F), it experiences the
stumble until it warms up (~ 5 minutes of driving) There are no
malfunction codes showing up.  Has anyone seen this?  I had a similar
problem on my old Conquest TSI, and it turned out to be the coolant temp
sensor.

Thanks and regards,

Subject: Team3S: ")oost problem

Donald...

I don't believe the stock turbos hold peak boost (9.5 psi?) for more than 1,000 rpm (roughly 3500 to 4500 rpm). Then the boost drops off sharply. Although I didn't have an accurate aftermarket boost gauge when I had stock turbos, it was clear that the boost was peaking in a narrow band, even after I installed a boost controller and set it at 15 psi. This is exactly why people invest in upgraded turbos along with injectors and pump. If you read the archives you'll see that Roger Gerl did some scientific testing (via an AWD dyno, not our more common "butt dyno") and showed that the most significant gains can be achieved by starting the upgrade path with the fuel system, not with the intake and exhaust as most of us have done.

Looking forward...Chris

Subject: Team3S: Weird(?) boost problem

Today I installed a aftermarket boost guage in my car
(Autometer -30-0-30).At about 2500 rpm in 2nd gear I hit positive manifold
pressure. Then at about 3500 The boost peaks to 8 to 9. By 5000 rpm the
boost has fallen back down to about 6, and by redline it is below 4. I made
sure the vacuum tubing is not getting pinched, by routing it through several
places. I even tried my friends tubing, all with the same results. Is it
normal to have boost that low, I thought that stock boost levels were 9-11
the whole way through the rpm band?

Ben...

No need to change the ECU or fuel rail to upgrade the injectors. Some
folks have used 560s, 620s, or 720s...depending on other mods. My
personal recommendation...stay away from the aftermarket "plug in" ECU
mods, none of them are worth what you get. In my case I wasted many $$$
with G-Force and never ended up with anything even remotely reasonable.
I pulled the daughter board and went with the ARC2/MAF fuel controller
which, while expensive, has provided excellent results.

All,

Some additional questions.

If full 3" exhaust, air filter, manual boost controller to 18Psi can
injectors/fuel pump be upgraded (size suggestion?) without having to
muck with stock ECU?

Can Stock ECU be mucked with (how important would an AFC be, what about
JET Module)?

Does changing injectors require larger fuel rail?

Ben.

My car ('91 R/T tt) does the same thing.  If I wait until the coolant temp
gauge goes past the bottom marker, it is ok, so that's what I do now.
Otherwise, it seems to me that the turbo kind of hesitates until I go into
full boost, then the car runs smooth.  I have no idea what the real problem
is, or if it is one.

Nah, stock 9b turbos are good to at least 19 psi up to about 4500 RPM where
they start dropping pressure.  Mine dropped to about 15 psi at redline, but
others have said they drop to as low as 9 psi at redline.

Without an accurate boost gauge there's absolutely no way to tell what the
turbos are doing.  The boost controller could've easily been not calibrated
correctly and you'd never know.

Hello again

I have had some problems to get the car to go well.
I took out the ECM and put in the owen for 3 houers at 50 Celcius.
Now the car goes perfect. Knock knock on wood.

Bye the way.
In Europe there are a lot of of Stealths and 3000GTs that have an engine whit 210 kW. Cant find that engine anywhere. Turbo?

Subject: RE: Team3S: Cold Start Stumble (slightly ot)

I have an Infiniti M30 which stumbles until it warms up and I know it's a
bad coolant temp sensor since the ECU reports that code. I'm not sure if our
cars report a bad coolant temp sensor. Nevertheless, assuming our ECUs do
report it, even if the sensor reports being "connected" it's possible that
our ECU only distinguises continuity vs. no continuity rather than good vs
bad. Will take a little bit of research. I'll comb my FSM and see what I can
find for you guys.
