Correct....
the reason is that the bigger turbos will "beat" the air less. Thus the
compressed air will be cooler...

And the cooler the air, the better

    This may be true.  All I really wanted to stress is that you must
decrease the engines resistance to air flow to get more horsepower at a
given boost.  If the engines resistance to airflow remains the same at a
given rpm,  a given boost pressure will always cause the same airflow.  It
is the boost pressure that drives airflow.  I guess I should have thought
this through a little better before posting.  A larger turbo will decrease
the engines resistance to airflow by allowing air to flow easier through the
exhaust.  However, it would be my guess the resistance is substantially
larger in the engine internals (heads, etc) than in the turbo.  If this is
the case, the larger turbo would change the overall resistance to airflow
only slightly.

    Sorry, I stand corrected.  I forgot about the effect of heat.  There
will definitely be a heat advantage with larger turbos.  The turbo gods will
have to answer how much of an effect.  I wonder if there is anyone who has
dyno'd a 3S at the same boost pressure (one at which the stock turbos are
capable of maintaining boost) before and after a turbo upgrade, with no
other modification.  It would also be interesting to take airflow
measurements before and after a turbo upgrade to see how much it has
changed.

Subject: Team3S: Turbo 101 - Chapter 2

I don't see how larger turbo's ALONE can increase HP. If I am running 14 psi
on stock turbo's all the way to redline in all gears, and I put in larger
turbo's and
run at 14 psi all the to redline in all gears NO difference in HP.  UnnnnnLess
the larger turbo's are delivering the 14 psi at a lower temp. to the IC pipes.
If this is indeed true, then the lower temp will in fact deliver a denser air
charge
to the intake. This I can see creating more HP.  Now the question is how much
of a temp. difference is seene between stock and bigger turbo's at the same
boost level.   Stage two would be increasing the cooling capacity of the IC
system to lower the temp. at the intake, making more HP potentially. Stage
three would be to increase the pipe size ALL the way from the turbo's to the
engine, which would have to include IC piping, IC cooler connections, Y pipe,
throttle body, intake plenum, and intake manifold.  At the same we need to
increasing the fuel delivery system to maintain a decent air/fuel ratio. It
seems to me that increasing the pipe size all the way is close to impossible,
so the next best way is to crank up the boost on the bigger turbo's to acheive
a larger amount of air delivered, hopefully without incurring too much of a
temp. increase. I would love to take a car through all of the stages after
installing every possible recording device including Tod Day Datalogger, EGT
probes, temp probes in various locations, air/fuel ratio, psi, etc, etc.  AND
have access to a AWD Dyno. Sorry for the long post, but I would like to
understand the process instead of just tossing money at it.

The stock fuel pump is rated at 180 lph @ 43 psi.

The FPR is boost dependant and set for roughly 1 psi of FP for each pound of
boost.  The stock FPR seems to top aout around 55 psi but some people see
more or less then that.

Hi I asked the same question a few weeks ago and Bob Fontana gave me this answer:

Bob wrote:

Fuel pressure changes as boost increases.  The stock pressure regulator increases fuel pressure 1 PSI for every PSI of boost.  Pressure at idle is 43 PSI.  When the charge air pressure in the intake manifold increases (where the injectors happen to be trying to push fuel into) fuel pressure must be increased correspondingly overcome manifold pressure.

So, if you are using 20 PSI of boost, you want to be able to maintain 63 PSI of fuel pressure.  The stock FPR appears to be able to handle it pressure-wise, but I'm not sure that the stock pump and injectors can supply enough fuel to match the A/F ratio needed at 20 PSI.

As an aside, when the RPMs are increased to over 3000, the shunt on the fuel pump is bypassed, increasing the voltage to the pump which helps maintain pressure when not under boost.  That's my understanding from the manual, anyway.  (Barry can probably give a far more detailed description).

  If I understand correctly, cfm is just as important a factor as psi, and the two don't
go hand in hand.  From what I gather, a more restrictive system could account for higher
psi yet not flow as much air, cfm, which would be a hinderance.  This theory is
supported by a previous post stating how many cfm various turbos can flow.  This raises
another question in my mind, wouldn't cfm be the important measurement when thinking
about the fuel system?  Wouldn't more cfm=more air and a higher need for more fuel
regardless of the pressure?

Subject: [Fwd: Team3S: Turbo 101 - Chapter 2]

>From general fluid mechanics: from the outlet of the turbo, through the
IC, through the Y pipe, through the throttle body, intake manifold, head
ports, around the valves and into the cylinders there is a give amount
of drag created. The drag is created by the side walls--the shape, size
and materials they are made of; intrusions into the air path (valve
stems, etc) and turns in the path. I think everybody can agree on that.
Now, given the drag there is a point at which, no matter how much you
increase the pressure in the path, you will not be able to increase the
flow through that path with temperature held constant. (Yes as you
increase pressure to infinity there will always be some increase in
flow, but the point I am talking about is when the increase in flow is
so small for a given increase in pressure as to be considered non
existent.) Everybody OK with that? (This is the concept that gives the
most problem: if you graphed pressure=X vs flow=Y there would come a
time when the graph would become, in essence, perfectly vertical.) Now
what ever the flow is at that time lets call that the max flow. So turbo
A will attain this max flow at some pressure, but turbo B, being a
larger turbo, can attain this same flow at a much lower pressure. As
someone mentioned here something comes into play, the higher the
pressure the higher the heat. This is not a good thing and we must add
IC to A to maintain that constant temp, but this will also increase the
resistance so there is only so far we can go with this. The bottom line
of this lengthy discussion is that I believe you would end up with more
power from the larger turbo once it got up to RPM.  You have to keep in
mind that spool up of turbo A and B would be analogous to A (smaller)
being 1st gear and B (larger) being 4th gear with regard to the
mechanical advantage given to the energy imparted from the exhaust to
the turbo with which to pump air.  This becomes the final trade off when
deciding how big of a turbo to use because, as we all know, turbo lag
isn't considered a good thing either.

This can all be calculated out; but, the mathmatics involved are
extremely complex because gases are not pure fluids. They have
compressability; so, we can't talk about just flow (notice my caveat
above). We have to look at the total number of gas molecules which,
along with resistance, is proportional to the pressure and temperature.

Well, sort of....

I never dynoed a 3S, but I indeed did exactly that with my 300 Zx
(just for the fun).

Everything being corrected to standard conditions, the power jumped by
a good 20%, at the same PSI. But keep in mind that the Z exhaust is big
enough
to flow.

And keep in mind that the measure was done on a dyno,  where the car is
stationary,
so there was no real good airflow to the intercoolers...

I know that on some 4 cylinders, WITH THE EXHAUST REMOVED, a "bigger" turbo
could yield to TWICE as much air going through the engine....but if you fit
the STOCK
exhaust back on the car, then it's possible that this "big" turbine couldn't
push
hard enough to clear the exhaust.

Should be a direct correlation with the HP increase.

And, BTW, that's the correct way of doing things. And that's why these
"upgrade
charts" based on BOOST PRESSURE are getting it wrong

I saw people replacing the stock turbos, thinking "if I use the same boost,
then I use the same amount of fuel", while in fact they were
maxing out their stock injectors, and experiencing massive detonation.

Maybe it's of interest for all who want to step up to a better fuel pump on a
decent price. I don't know much about the Walbro pumps but the price is very
good ! The flow is given up to 255 ltr/hr compared to our 180 ltr/hr stock pumpy
but you better check back with the guy.

http://24.4.36.39/ape/fuelpump.html#overview

Remember the GP ends at March 26.

I do have a DENSO pump ready for installation and I was told it is a 90 gal/h
unit (price was around $400). This would result in 341 ltr/hr and is really
high. Unfortunately, nobody was able to tell me on what fuel pressure this is
measured and I beleive it is at 0 psi ! Therefore the figure will be lower at
43psi for sure.

LOL!

  I dunno for sure, but perhaps the key would be whether the stock turbo can flow more
air than the pipe will alow.  Perhaps the pipes can flow more than 5 tons an hour and
then all you need to do is gives da pipes more air with bigger turbos.  Again, I'm not
sure, but I would think at some point the pipes themselves would need to be bigger to
flow enough air as to not be a big restriction.  Maybe stock pipes would flow enough to
put on 356g turbos, but if ya wanna go bigger you need bigger pipes to see the
advantage.  I would think that the first recommended mods would be to upgrade
restrictions to allow benifit to be seen when upgrading other things.

Guys,
I've got a problem:  the short of it is that 2 of the joints of my
power antenna seem to be really sticky.

The long of it:)

The motor is fine, as is the relay (as best as I can tell).  This all
started when I noticed that under normal operation, the antenna didn't go
all the way up (1 joint didn't telescope).  Being the perfectionist I am
when it comes to my car (I know, I know if it ain't broke...but) I tried
"helping" to motor extend the antenna by gently pulling on the antenna as
the motor was extending it(before the relay cut it off), and got the antenna
to extend fully.  It was kinda dirty, so I cleaned it with alcohol, hoping
that that would get some of the crap off of it.  It did.  Really black paper
towels...  Then the antenna would go down, but not all the way.  I could
again "help" the motor by lightly pushing on the antenna as it went down.  I
grabbed some silicone spray lubricant and wiped that all up and down the
extended antenna.  Stupid thing still won't go all the way up or down on its
own.  Worked on it for 30 minutes trying everything I know...no cigar.  I've
got it now so that when all the way retracted the motor will extend it up
except for 2 joints, and can successfully retract it from said position.  I
think this doesn't hurt my radio reception that much, but it really annoys
me.   Any other suggestions for how to fix this?

Subject: Team3S: more turbo theory 101

Time to throw in my 2 psi...

Engine power is directly related to the density of the air/fuel charge
in the cylinder.  In a normally aspirated engine the air charge is
sucked in.  In a turbocharged or supercharged engine it is pushed in.
Increasing the air/fuel density will provide more power (assuming the
air/fuel ratio is already at optimum).  The air/fuel charge density can
be increased by:  1) reducing engine flow restrictions;  2) increasing
boost pressure;  3) reducing temperature of charge; and probably others
I forgot about.

Our engine will consume 3.0 liters of air/fuel for every cycle.  The
density of this air/fuel charge at 0 psi is a lot less than at 15 psi or
21 psi.  If someone does the math, one could calculate the amount of air
in cfm required at lets say 7000 RPM at 0 psi, 15 psi, 21 psi, or any
desired boost level.

The main problem with small turbos is that they can't provide enough air
flow at maximum (7000) RPM at higher than stock boost.  Also the
temperature of the air charge is higher than would be in a larger
turbo.  The main reason for going to larger turbos is to provide the
required air (cfm) at your chosen maximum RPM at your chosen maximum
boost.  This will give you maximum power over the entire RPM range. 

On our cars, stock 9B turbos will hold about 10 psi at redline.  13G's
will hold around 15?? psi at redline, and 15G's will hold 21?? psi at
redline.  (Perhaps someone can supply real numbers for the 13G and 15G
turbos.) 

Bottom line:  If you want to maintain a higher boost at redline, you
need larger turbos.  By reducing restrictions and lowering air/fuel
charge temperature, you will get a higher charge density for a given
boost level.

===========================
Erik...

The "spider" effect you describe is usually caused by impact. I have some on
my lower left bumper area where it connected with the ground as I slid off a
highway two winters ago. Since the bumper skin is plastic, it tends to
"fracture", resulting in cracks in the paint. With some cars, there's also a
paint adhesion problem if the plastic parts haven't been cured properly, but
I haven't heard of that with Mitsubishi's. I haven't had mine painted yet,
as it really isn't noticeable unless you've got your nose on the ground six
inches in front of the car (normally a poor position to be in). Fortunately,
my paint hasn't peeled yet. My plans are for a show quality paint job in
Y2K, if it started to peel today, I'd go for the touch up paint.

Good luck!!!

Just a clarification point here.  Because it is a four stroke, the engine
consumes half its displacement every revolution.  You stated every cycle by
which presumably you mean RPM x 2.  This is just for anyone who may be
setting down to do the math so they remember to divide RPM by 2 to get
intake strokes.  So, air consumption is (RPM / 2) x displacement x + - / a
whole bunch of other terms that account air density, vapor pressure, fuel
charge, turbo efficiency, i/c efficiency etc. etc. As you say, it is
complicated.

Subject: Team3S: Arty

Please contact me either today or tommorow about the 17" wheels for
1991-1993 3/S cars.

If anyone knows Arty's full name, please tell me... it would make looking up
his number much easier. I really need to get rims soon... I messed up my
current right side ones by hitting a pot hole.

Subject: Re: Team3S: Paint Cracking and PEELING!?!?

It sounds like the front mask was painted with standard lacquer and
not urethane with the elastomer to let it stretch on the flexible
portion of the nose. Heating, cooling and flex is cracking the paint,
which is brittle because it was intended for a rigid surface. You
can't add elastomer after the fact, so I guess I bring bad news. Hope
I'm wrong.

Seems that Extreme Motorsports in Jessup, MD will be installing an AWD dyno
in the next couple of weeks.  Good news for all of you people in that area.
