Subject: Boost levels (was Re: Team3S: xenon drop-ins)

Thanks a lot for the info. I think I'm gonna yank the Street Glows and wait
until I can afford a true HID conversion...

On a different subject, I was reading this article (link at the bottom) and
it was saying that the car was running at 28 psi and the owner wanted to run
it at 35. I'm just trying to figure out the gapping hole between those
levels and what are considered "safe" levels for our cars (< 15 psi).
Where's it coming from?

On the bulb topic..

Beware high-wattage tinted bulbs.

They -are- darker than OEM clear ones.

A few factors...

The Supra engine starts off with being less detonation-prone than our motor.
I'd guess (just a guess) that their head has a better combustion chamber
design than ours.

He has JE forged pistons - our stock cast pistons are only good to somewhere
around 22 psi on a good day with race fuel.

He has Crower rods.  Haven't really heard about problems with our rods, but
there aren't that many people that run huge boost on our motors so the
amount of data isn't that large.

He's got 720cc injectors - plenty of fuel for running that kind of boost.
Don't even think of running that high on stock Mitsu 380cc injectors.
(You'll hit fuel cut way before you get that high anyways though).

...and of course you need to have larger (and more efficient at that
pressure level) turbos to get that kind of boost in the first place.

A properly prepped 3/S could probably run higher boost on pump gas without
excessive knock - but you need to have great ways of monitoring what's going
on with the motor so that you can determine what is safe for your particular
setup if you are going to tune to the ragged edge.  You can cheat and run
more boost on a not-so-properly-prepped car by running water injection or
alcohol injection to prevent detonation.  I'm also going to be using colder
plugs in my motor to see if I can get some more headroom before detonation
once I get my motor back together.  I suspect at least some of the
knock/detonation is coming from too-hot plugs.

Obviously you can see that the guy who built up that Supra did a number of
things to make it survive those kinds of boost levels.  With similar care on
a 3/S motor you might be able to get closer to those numbers.  The question
is: how do you do it, and what's the recipe to get there?

Also keep in mind that the 28 psi number is being run on a combination of
110 race fuel and pump gas which should have a higher detonation threshold.
35 psi is probably high enough to cause serious damage to the
pistons/crank/rods if the tuning isn't dead-on, even on 118 octane race
fuel.

If you start enhancing parts of the car (more efficient intercoolers, better
fuel control, better base timing control, more exotic per-cylinder
knock-based timing control, etc.) then you can start going past the 15 psi
"accepted safe" number - but monitor knock somehow (which on your '95 you
are limited in your choices).

Of course, you always want to be a little skeptical of what the magazines
print.  They just repeat what the owner hands them - these numbers could be
"inflated" (ie: was it really 100 degrees in the dyno room, or was it really
60 degrees and the corrected/plotted numbers are incorrectly corrected?).
I'm not saying they are, just saying that magazines don't necessarily always
get the facts right.

Hi Jeff,

The Brembo TBA goes way back to 1998.  I had
corresponded with a Brembo guy named ??? Collins I
think.  Nothing ever came of their TBA back then.  I
suspect they decided not to persue as the MOVIT and
Brad's Big Red kit were available.

Also Brembo reportedly is the manufacturer, to
Porsche's specification, of the BIG RED caliper.

Hi Wayne,

The article lied.  The closest cars are the 300Z turbo
and the Supra Turbo.  The 300Z has almost the
identical pad to ours AND if you ask any Z owner who
does road track, they'll tell you the brakes are just
as louzy as ours.

The Supra on the other hand, has a much larger pad and
a larger dia rotor with directional veins.  The Supra
can stop repeatedly better than ours.  Yet the serious
road course Supra owners even upgrade their braking
system.

I don't want to minimize the *&###$%*@) Getrag
transmission problems though.  I had FOUR (4) replaced
under Dodge warantee.  Fortunately the current tranny
has held up for the past 23k of road courses.

Be of good cheer,
John

Nobody does who doesnt have a solid fund for a new O2 sensor every few

Cats or not..you need your O2 sensor to make the car run right..and THAT
precludes leaded fuel completely..unless you dont mind replacing them
every few events.

The considered safe boost levels for our cars is based on a stock fuel

able to run those extreme pressures. In my Stealth, I have already run 25
psi. My fuel system seems to be able to handle it. However, I am now

Yes, EGT should be measured in the manifold, before the turbo.
However, you could use one of the bungs/fittings to attach a 10-12
inch ~1/8"-1/4" ID metal pipe. To the end of this pipe would attach a
silicone rubber hose that goes to a pressure gauge/meter of somesort.
This would allow you to measure pressure in the exhaust after the
turbo, and before the main cat. Why do this? I guess so satisify
curiousity and maybe to see if you need to kill the cat (clogged or
otherwise causing too much restriction in flow).

As far as I have heard, the Supra owners have no way to
measure/detect knock (other than the standard aftermarket setups). So
how could they know if they have knock or not? Of course, the same
question can be asked of 1994 and later 3S owners.

Subject: Team3S: Re: Boost levels

1) 35 psi boost.
As far as the turbo itself is considered, it can only multiply intake
pressure by a certain maximum factor. For most turbos sized to fit
1.5L engines (twin setups), the max pressure ratio (PR) is in the
range of 2.8 to 3.1. Assuming 14.5 psi into the turbo and 3.1 PR
factor, the output pressure would be almost 45 psi, or 30.5 psi
"boost". That is of course before any pressure loss in the IC system
and intake manifold/plenum. 28 psi really is the practical max we are
likely to see in our cars with *typical* upgrade turbos. Turbos to
fit larger engines, 3 to 4L or larger, can have max PR of 4 or more.
The key of course at any PR is the flow, which varies from turbo to
turbo. Secondary to flow would be compressor efficiency (how much it
heats the air up after normal adiabatic compression heating).

Pressurization primer for our cars:

2) Safe boost levels or 3S cars.
For stock cars, the limitation is fuel and maybe detonation - 360
injectors and 180 lph pump. For upgraded cars ??? Maybe the strength
of the internals and detonation?

I got passed by a Supra at Road America. I was running about 120+ on the

Thanks, but I believe what I need to know is what sets off the Check Engine

Trevor if you are out there, could you give me some insight.

They have a knock sensor, but the typically-used TMO Datalogger doesn't work
on those cars so the knock values in the ECU are inaccessible (at least for
now - until someone figures out how to read it and implements it in a
datalogger).

'96 and later cars can use an OBD-II logger to watch timing advance, but not
direct knock values.

Subject: Re: Team3S: Poor Gas mileage and getting worse

The O2 sensors could be going, yes.  Replacing them is $120 for both, plus any
labor if necessary.

29-32mpg highway, sorry to say, sounds impossible.  Even with my boost turned
down to 6psi and in 6th gear, I can't pull any more than 24-25mpg on the
highway.  Especially with a test pipe!  The mods you've made allow max airflow,
more airflow = more fuel needed at same rpm = lower mpg.  Certainly not to
discredit you and your mileage readings, but maybe it was running too lean
before?  with no cat(s?), you would not notice a lean condition as easily.

Also remember the transmission/speedo gear issue, that causes the speedo to
read high.  If it reads high, so does the odometer, and this would give you
falsely high mpg readings.  You didn't change the tranny/tranny gear lately,
did you?  Also, I would get those plugs and wires finished.  If they are
hurting you, the back O2 sensor is getting a far different reading than the
front, and car will instinctively run at the richest demanded.  Then, the extra
fuel not being burned will accumulate on your pipes, more than normal.  Oh, and
cats convert extra fuel (HC's) into carbon dioxide and water, which won't leave
black all over you and the guy behind you.  I have to wipe my pipes ever month
or so, and I have some pretty good mods too..  Well, I hope this doesn't sound
like rambling, I'm shooting my thoughts out quickly trying to give suggestions,
have to run now so good luck!

I didn't say "no knock sensor" - or at least didn't mean to. These

knock sensor info out of the ECM - *yet*. :)

Supras and 1994+ 3S cars are just "guessing" as to knock levels.
Until the Supra knock sensor info can be extracted from their ECM,
we/they don't know if they have less detonation prone engines or not.

Sure the ECU still handles it - to a point.  It can retard timing when knock
is detected, but if you keep pushing the car hard beyond where retarding the
timing is sufficient to keep away detonation then there's nothing more the
ECU can do (it might* go into fuel-cut mode, but maybe not if you've done
other things to the car like fuel injectors and a fuel controller).

Advancing timing causes more severe knock (if you are already knocking),
FYI.

It won't flag a check engine light due to knock - you'll see the CE light
when the car dies from the broken pistons though.  Or maybe not - my car
never flagged a CE light even though two pistons were broken and the car
barely ran enough to get the 1/4 mile to my house.

Subject: RE: Team3S: Brembo 3S Specific brake upgrade

With regards to rotor warpage:

Warping of the rotors is an phenomenon which is completely independent of
the type of brake pad compound being used.  Rotors will warp when they are
allowed to cool unevenly; i.e. one part of the rotor cools faster than
another part.  This will often occur when you park a car when the brakes are
very hot, such as when coming off the track.  The part of the rotor which is
facing the pad is subject to the intense heat radiating from the pad, while
the rest of the rotor is allowed to cool, as it is exposed to the air.  For
this reason, I recommend that after every track session, or even when
driving aggressive on the street, that you take a cool down lap (on the
street, just drive the car around for a few minutes to cool everything off)
or drive around the paddock area a couple times.  If you can't put your hand
on the hub area of the wheel and not burn yourself, it is too hot, and you
should keep driving.  Also, never use your emergency/parking brake to hold
the car when you come off the track, as this can cause the rear pads to bond
to the rear rotors, or at the very least, promote rear rotor warping.

Also, Carbotech Engineering is now offerring out Panther Plus compound for
Porsche 993 TT calipers; this is the CT594 pad.  Please call if you would
like to order a set of these pads.  Team3S members receive a 10% discount

I have disputed the following statement before, and would like a few
more opinions on it.  Gas mileage should not be affected by most
performance items such as high flow cats, downpipes, free-flow exhaust,
air filters, etc. etc.  This is my theory at least, because no matter
what mods you do, the amount of air, and thus fuel at whatever RPM is
limited more by your own foot (which is connected to the throttle body),
rather than what mods you have.  Sure, if one mod causes you to run rich
/ lean, I can see the MPG difference, or if you change your driving
style because you now have more power at the same throttle position now,
but overall, shouldn't most mods keep approximately the same MPG???

Most mods have little to do with performance at low performance levels so
normal driving [ non-WOT stuff ] should result in about the same fuel usage.
I would assume that it's pretty easy to screw up the settings on a fuel
controller though ---- it seem like it would be easy to set an ARCII  to run
rich at low power settings and mess up fuel consumption.
