Subject: Team3S: Twin pipe
gasket
I just changed my plugs (not too bad a job) and found the seal
between the inlet "twin" pipe and the throttle body was destroyed.
Apparently a mechanic along the way forced it on without watching what he was
doing and cut the gasket which left about half of it inside the pipe, blocking
my intake. No wonder performance was poor! Anyway, I've seen other
postings about replacing the gasket. Are they available? Are there
substitutes if not?

The seals are not
available; if you can't reinsert the rubber onto the pipe and repair with Super
Glue (worked for me) you have to change the pipe. Can get stock pipe, or
get metal version that should hold better on high boost from Alamo (black
crinkle fininsh steel) or ?ATR.

Subject: Team3S: gasket
remover?
Could any suggest, if there exists such a thing, something that
would remove
old gaskets? Specifically the water pump gasket. It looks like a
paper/fibre
type gasket, could be rubber, and has been sitting on there for
the past 7
years. I'd really like to get it all off and not have to resort to
scraping.
Maybe a good soak with wd40 will do the trick?

PS My engine cleanup is coming along nicely. Almost everything is out
except
for the motor, transmission, power steering, A/C and brake stuff.
Almost all
tubes, hoses, wires and such have been removed for cleaning, as
well as the
throttle body, plenum, intake manifold, injectors, etc. What
color would
look good on the plenum? I was thinking yellow, as the rest of
the accents
on my car are yellow, and i'll put yellow vacuum tubes and such
in. How
about the valve cover? black with yellow letters? Ideas are welcome
for
consideration.

I am very satisfied with the
Porterfield pre-treated stock rotors..
cost me about $60each plus $50each for
cross-drilling. Their
workmanship is superb.. they look alot better
than the cross-drilled
rotors that came with my Brembo kit.. which cracked
after 3-4 weekend
of racing.. the pads for stock caliper is $129/front set..
for Brembo
caliper $159/front set.. if they don't know what size or part #
the
pads for our Brembo kit are.. just tell them u want pads for
the
Ferrari F40!! =)
I happen to have a pic of the rotors.. I'll email
it privately to you.
Anyone who wants to see it please email
me..
Porterfield's #: 800 537 6842.. hope this # still works.. haven't
been
there or call for over a year..

Re: Team3S: Track report
Hi Rich,
Great report. That is
incredible that two PowerSlot rotors cracked at
two different times, each on
their first day of a track event. I guess
they can be ruled out for
extreme performance conditions. Try the KVR
or Porterfield rotors next
and give us a report. Maybe you'll also want
to talk to Brad Bedall
about his brake kit that replaces the stock
calipers with OE Porsche (Brembo)
and the stock rotors with KVR.
This information is extremely valuable
since I know many folks will
upgrade their brakes in the future. I'm
sorry it is so costly for you
though.
Thanks,
Ken (eagerly awaiting
the next report on different rotors)

How what is
the performance like over stock? And what do you mean
by "Porterfield
pre-treated stocker". Is this a "stock" rotor with some type
of treatment?
Also does the brembo kit increase the rotor size? This kit is
seemingly not

Calm down, there is no need to yell at
us.
Go to this link : http://www.ultimategarage.com/bigbrake.html
These
brakes are using the big Brembo calipers with Porsche mods. Also the rotor
is
from Porsche, but not for all applications. As far as I know they are made
by
the same company as the Bremsas then and also use then the same blue
anodized
Erdal hub. I think the ones for our cars will be like
that.
Spend mucho money and you have your brake system

Busy Weekend
Hey all:
As I mentioned in my previous post, this
weekend began the reclaiming of
the car back to "normal" from old man
winter. Besides the cleaning of
the "snake eye" lenses, I also did
Wayne's fog light mod (thanks much
Wayne!) and I tapped into the extra
accessory plug wires and ran the wire
for the radar detector in the dash,
allowing me to actually reach the
radio controls. I also reattached a
tailpipe that was thinking of
falling off (one side of the u-shaped arms
where the screws go in had
broken off) by using a stainless steel screw
through the drip hole. I
drilled directly up the middle of the
pipe. This was amongst waxing,
cleaning, etc. It almost looks
normal again. And I cleaned the backside
of the "snake eye"
lenses, which made a huge difference.
You may remember myself and another
having our SRS lights come on
recently also. Well, my anti-lock light
just came on too. I've got to
believe that this is related to simply
running a diagnostic's on the car
at a preset mileage as it's never run
better. Anyone? Seems way to
coincidental to
me.
Best,
Scott

Unfortunately, this proves what frinds from the
Camaro/Firebird lists
experienced. PowerSlots work good but over a specific
temperature they will go
:(( If you have them on your car just be aware not
to overheat them. Did you
felt a fading before the crack ?

And you know why ! The rotors are not able to take up the heat and
therefore all
other parts will be heated up too. Especially the pads and the
calipers. Finally
the brake fluid will start boiling if the rotors are not
cooled enough to take
the heat away.

Yes, put Bremsas on it, go for the Porsche
setup or spend $6000 on the ap-racing
setup. If you stay using the PowerSlots
it's just a matter of time till the
stuff cracks again and you're in danger
to go off the track. You're lucky not
ended like the M3 or
Porsche.

Any little air that helps to cool down the
rotors help. Why not installing a
thermocouple to the calipers to check out
the real temperature. After my last
driving class the Bremsas were really
damn hot and I burnt my finger. The Pagid
pads look more worn than expected
with typical signs of overheating (looks like
very small parts left the pads
and caused small holes) You can also see some
small grooves on the rotor
then.

Well, I think only good rotors, a
set of expensive pads and braided steel lines
(dunno if you have them
already) will bring you forward. Going to the Brembo big
brakes will help you
from the calipers view. Interestingly, the Brembo upgrade
uses smaller rotors
than my EU car has stock ?! For about $2650 you should be
able to get the
MovIt Porsche/Brembo upgrade for the fronts (gulp) IMHO, this is
the best
bang for the buck and I heard nothing but good about them (Supra,
M3,
M5).
BTW, just always bleed the brakes before you go to the track.
Only a little air
in it helps to heat it up more then
normal.

Roger

Hey
Gavin,
I don't know if anyone from the list is interested in our
little
discussion here.. so if you have more questions or thoughts
please
email me privately... I don't want the TEAM 3S police pulling us
over..
hehe
As for the Brembo rotors.. I think they were
12.8in.. and the '93+
stockers were 13.1in.. I've heard the 13.1 rotors will
not fit in 1st
gen wheels.. besides.. i don't think bigger rotors adds to
braking
power.. it's all about the calipers..
As for
'Porterfield pre-treated'.. they heat-treat the stockers to
make them
stronger and will stand higher temp.. atleast thats what they
told
me..
The Brembo rotors are not impressive.. the caliper is.. If
you are
into road racing and need constant stopping power from 140+mph
laps
after laps, this is the way to go.. if you're into 1/4mile
or
occasional street/hwy races.. maybe the stock caliper is
sufficent..
maybe.. hehe
On a side note.. a friend of mine..
(remember 'White Lighting' years
ago?? haha).. we tested out our top speed on
the long straight stretch
of road to Vegas.. he hit 180mph (on his
speedometer).. then tried to
brake.. his stock brakes completely failed..
luckily there was no
traffic at all and the car eventually slowed down.. I
tried the same
thing.. didn't quite hit 180.. about 175.. i was scared =( ...
but my
Brembos worked!! The moral of this story?? hmm.. Got
Brembo??

I think we just heard in a previous post that Brembos crack.
As I
understand it, the Brembos remain in one piece, and just crack at the
drilled
holes. If they are breaking apart like mine do, that's
dangerous.

Yes, but it was at the end of the session, and my brakes

Unless PowerSlot comes through with a better solution, I am done
with them.
I've been lucky both times that the rotors snapped at either a
reasonable
speed or in a location where I could handle suddenly having no
brakes at
all. The other problem is that when they break in two like that,
they can
very easily slice off the caliper. I don't care to take that chance
again.

Any particular reason why
the stock brakes would fail due to high speed? Or
was it excessive fade due
to repeated hard use? I've had my VR4 over 140mph
a number of times and plan
to peg the speedo with my new mods. The thought
of tripping some hidden

cramp my style. :-)

Whoops, I think you misunderstood me. In
Brad's kit, which by the way
is about $1500 last time I checked, only the
calipers are OE
Porsche/Brembo. The rotors are KVR. As far as I
know, no one on any of
our lists has broken a rotor by KVR or
Porterfield.
Maybe Brad can join this discussion and add his
experience.

Chris,
This particular 180mph

weight of the car and imagine the
velocity of it at that speed.. i
think the stock calipers just didnt have
enough power to grab the
rotors.. there was no excessive braking prior.. i
would imagine a big
difference in the power needed to stop our cars at 140
and at 180...

Team3S: Walbro Fuel Pump Upgrade vs. HKS
Hoping to get some good feedback
here.
I recently found an amazing deal on Walbro fuel pump upgrades for
the
VR4. Now originally I was going to get the HKS upgrade but for the
price
I don't know. The Walbro flows 255 liters per hour, what does the
HKS
flow? Does the Walbro simply slide into the stock mounting brackets
like
I heard the HKS does, or does it require modifications? And does
anyone
know how much HP a Walbro will support? Or is everyones opinion
that the
HKS is the way to go.

Friends,
> As for your Brembo
upgrade, I recall that you complained about it recently.
Please don't
mix-up the Brembo upgrade and other upgrades using Brembo parts !
The
known Brembo upgrade is from Stillen using their own rotors and
Brembo
calipers used at the F40 (nice older Ferrari, not that heavy car).
Dunno about
the pads. I heard different things about this kit and they were
always bad on
the rotor side. I think the price was around $2150 for the
fronts but some had
trouble when doing the calipers (bolt cracked, rotors
tend to crack from the
drills to the edge).
Then there are other
combinations like the ones from MovIt. They use the Porsche
rotors together
with some newer Brembo calipers modified for Porsche (larger
piston
diameter). Also you can get the calipers with KVR discs and pads. The
price
is around $2750 and yes, it is available for our cars. Some people
just
update their web site once a year ;-)
I can even get this kit
together with the Bremsa disks from my supplier but the
price is huge
(gulp).
On the physics side it's very important

A big
NO here ! Larger rotors are able to move more heat away due to the
larger
surface. Also the way the rotor travels trough the pads on one turn is
longer
the larger the center of the calipers is away from the axle. Therefore
a larger
diameter is not getting that hot as a smaller one. Simple physical
things.
Bigger calipers are having a larger area that can remove more
heat away from the
fluid and the pads. The power of our stock calipers is
very good and I can tell
you a great stopping power with the setup I do have.
As said the bigger calipers
will help to remove the heat as well as they are
needed when getting larger
disks/rotors.
Please also do not forget the
force that acts on the parts at the suspension ! A
kit for our cars MUST
consider the weakest elements on the front suspension
parts and this is why
no 330mm setup is available. This stopping power could
definitely crack some
parts around the wheel and this is too dangerous. As far
as I know the 321mm
is the max size with a 4-pot caliper and 30mm thick disks.
An ap-racing
caliper would fit 17" while using the Brembo caliper needs 18" with
this
large rotors.
Regarding the price, you'll get what you pay for. The
danger of a cracking rotor
and the damage that could occur would be worth
this money. I do not often race
the car than on a small test track here in
Switzerland. It is large enough to
get the stock ones fading and loosing some
seconds. I paid about $1000 for the
Bremsa disks/hubs and another $200 for
the Pagids. On the track or when braking
down very hard they are amazing and
the rear ones just completed this (they
helped to keep the car straight when
braking hard). How much worth is security
and braking power ? If you go for
such a race every once in a month, just do the
calculation. Maybe $2000 -
$3000 is then not too expensive anymore.
If anyone is planning to install
a bleeder valve (urgh) he will have more power
but not the power to stop. If
you plan to go the power path you must also go the
way to stop your monster.
I thought this right after installing the BC and got
the new sets of rotors
only a week after the more power kicked in.
Unfortunately, this is the
expensive way, but if you don't want to go this, then
watch out every turn
and feel like the brake pedal is vibrating more and more.
This would scare me
too much :)

Roger

Yes it flows better but no, it is not a direct
replacement. You need to get
banjo-adapters or more to make everything fit.
But the stock one is good and I
don0t plan to replace it until the big AFPR

Well, here the BIG question kicks
in : On what fuel pressure is this flow
measured ??? The Walbro you refer is
the smaller one but they do have the bigger
one available that flow up to 290
litres per hour. If the HKS (Denso pump) is
measured at the same flow than
you'll get around 341 l/hr.
The hp capabilty is not worth to mention as
this depends too much on other
variables (or who know how much hp our cars
are making at 290l/h ?)

Why are you planning on

BTW...whoever was curious...the HKS

It replaces the stock unit quite

I'm not sure but I think the limitation is not the MAS at this
time. The 13G may
peak up to 1.3 bars but good boost is around 2.5bars. The
13G may not be able to
feed more air as the MAS can deliver
anyway.

A bigger fuel pump is a MUST anyways
as the injectors are. It seems you just
want to dump in the fuel to prevent
detonation. With this you are wasting some
energy and I doubt that you'll see
the 11s. Maybe with really loosing some
weight (I mean the car) but I'd vote
for 12.15 at best.
Go for it and check it out. If it doesn't work liek
desired you can still go for
a VPC later (by selling the AFC then)
Let
us know how it works :)

Fine-tuning and increasing the
flow from/to the fuel rail including replacing
the small connection pipe. I
already have the Paxton AFPR and fuel filter but
have not decided yet how to
mount everything (and where). After the 720cc,
bigger pump and the ECU I

Re: Team3S: High 11's w/ stock Turbos?
A while back you guys were all
debating about whether
or not a VR4 could run 11's on stock
turbos.
Well, if I'm not mistaken, it has already been done in
Japan
by the green Puma GTO N1, a second-gen VR4.
It ran 11.99 in the 400m, and
according to its spec sheet
(and Henry Yam) it runs stock turbos because of
the
class it races/raced in. The car is completely gutted
w/ a
rollcage with a total weight of 1460kg (3220lbs),
and it runs full slicks
with about 8 degrees of neg. camber.
That's all for now.

Re: Team3S: RE: Brake failure???
Chris,
I have the Stillen
rotors. These are basically the stock size rotors,
but they are
crossdrilled and have some vanadium (gold like color)
coating that supposed
to prevent them from rusting (no rust = better
thermal
conductivity).
I've only done autocrosses so I couldn't comment about
stopping from
140mph turn after turn, but all I can say is that in a few
autoXs I had
to break from 80mph down to about 15mph and the first few laps
it was
OK, no detectable fading but the 4th one, I just couldn't stop.
On top
of that there was a lot of smoke coming out of my front wheels.
One aspect about AutoXs is that you get about a 15min cooling period
in
between laps so I'm sure that if I had to run continuos laps the
breaks
would have failed on the last part of the 2nd lap or the beginning
of
the 3rd.
Luckily for me, no broken rotors yet!
In my
opinion, the best way to get a very good brake setup is upgrading
to either
the Bremsas, or the Porsche kit and then removing about 800
lbs from the
car... ;)

Team3S: Boost ? ? ? ? ? ? ?
Hey Gang,
Well it looks like I'm
thinking of doing a " Second Wave " of mods on my VR4
( This is the same guy
that said " Its going to stay Stock " - Yeah Right )
Anyway, I'm thinking
of doing the following on my car :
1. HKS Super
Sequential Blow Off Valve
2. HKS Fuel
Pump
3. AFC ( or similar mod :o)
Mods currently on
car are just the basic stuff :
Custom Exhaust, Downpipe, K&N, HKS EVC
IV, and a boost gauge
So . . . .
. . . the question I want to ask is ,
can I up to boost to 16 - 17 lbs with the aid of
the expected fuel mods
.
( If not 17, then at least 16 ? )
Please keep in mind that I will still
have the stock injectors and turbos ( So is this
all just a pipe dream
:o)
ALSO : Since my car is a 1996 VR4, will it set off the OBDII software
in my computer (
e.g. the AFC ) ?
Thanx for any help you guys can

Team3S: Adventures in braking-1999
Judging by my problems and those of
others, and the posts winging their way
from Europe to the US and back, we
have a serious braking problem with our
Stealth/3000 GT turbo cars.
It's simple: we are trying to stop a 3700 lb car that goes very, very
fast,
and its stock brakes are not up to it.
Problems
include:
PowerSlot slotted rotors tend to break. That is, the rotor separates
from
the hub.
Stillen drilled rotors tend to crack at the drilled
holes.
Brembo/Porsche parts are very, very expensive and still don't do the
job.
We go through a set of pads PER DAY at open track events.
We need
to find a solution.
I propose that we establish a little corner of the
two groups devoted to
braking. Anyone who does not do any serious racing can
ignore this
discussion. Just put "Braking" in the subject line, and those who
don't
care can ignore all this.
First of all, we need to find out
what DOES NOT work. For this, we need
horror stories. If you have done any
road racing, autocrossing, rallying,
or any other endeavor that requires
using brakes, please come back and tell
us what does not work.
We
need to know:
What racing you do?
What parts did you use (rotors, calipers
& pads)?
What happened? What went wrong? Did the rotors break or crack?
Did your
pads wear out?
Second, we need to find out what DOES
WORK. For this, we need success
stories. Again, if you have done any
road racing, etc., and your system
worked, please tell us about it.
Third, we need IDEAS. There are dozens of brilliant engineers and
racers
on these lists, and we ought to be able to solve anything.
Just to get us all started, read my second post. It contains all
three
topics.
PLEASE contribute if you have anything that might help.
Our cars are very
cometitive in open track events, if we can just stop
it!

Subject:
Team3S: Adventures in braking -- Old poop inputs
As promised, here's my
input to the discussion.
I humbly suggest that everyone who wishes to
contribute follow this format.
WHAT I DO
I run Porsche Club driver's
schools/open track events. Done three so far. I
am in Group 2, which includes
folks who have taken the novice driver's
course. I have run only at Heartland
Park in Topeka, Kansas. I run
PowerSlot slotted rotors with Performance
Friction 460Z PGD 631 pads.
THINGS THAT DO NOT WORK
PowerSlot
slotted rotors do not work. I have broken two of them at open
track events.
In both cases, under hard braking the rotor broke away from
the hub,
rendering the entire braking system useless. Breaking a rotor in
half at high
speed can also result in the loose rotor slicing off a
caliper. I will never
use PowerSlot rotors again, and I urge you to not use
them either. The
suckers are DANGEROUS.
ABS does not work: Our ABS cannot deal with
the loss of one wheel. It just
gives up. Lose a rotor, and you lose the
entire system.
Performance Friction 460Z PGD 631 pads do not work. Oh,
they stop the car
allright. Like dropping an anchor. But they only lasted
three 20 minute
sessions. They work, but their life span is unacceptably
short. Which
means, for our purposes, they don't work.
Stock rotors do
not work. They get hot and warp.
THINGS THAT DO WORK
I installed
a duct system to bring air up from simple 1 x 6 in. scoops
under the front
valence directly to the calipers. I removed the dust plate
from the back of
the rotor, fabricated a bracket to hold the ABS sensor
cable, and ran a
length of round 2 in. industrial duct from the scoop to
the opening behind
the caliper. I've had some minor problems anchoring the
duct at both ends,
but it seems to work. By "work" I mean that it seems to
have kept the
temperatures down somewhat. Without a sensor I can't say how
much. All I know
is that the brakes no longer smoke, and I can work on them
as soon as we pit
the car (after some cooldown laps). Last year, I could
not go near the brakes
for at least 15 minutes.
IDEAS
1. Disconnect the ABS: As
noted above, it is dangerous if a failure
occurs. Besides, disconnecting the
ABS may permit idea number two:
2. Install a brake proportioning valve,
and move more braking power to the
rears. At present, the rears are more or
less useless. With the ABS, they
contribute very little. I'm still running
pads from last year back there,
and they show no signs of wear. I suggest we
dial some rear brake into the
stopping equation. I suspect that the ABS will
not permit a proportioning
valve, which is why we may have to disconnect
it.
3. Install a water cooling system in the air ducts. A Trans-Am
racer
suggested this to me. All we have to do, he said, was to install
a
windshield wiper squirter in each air duct line, and connect them to
the
brake switch. Whenever we hit the brakes, each would squirt cooling
water
into the air duct. The water would vaporize in the air flow, and help
cool
down the brakes. He wasn't too specific as to exactly where the
squirters
should be-- up front at the air intake, in the middle of the duct,
or very
near the calipers. Ideas, anyone?

Subject: RE: Team3S:
Adventures in braking-1999
The Brembo/Porsche solution isn't really that
expensive in the grand scheme
of things. In fact, it is likely the most
economical and biggest bang for
the buck out there. When I refer to
Brembo/Porsche, I am referring
specifically to a setup similar to what Brad
Bedell put together, not the
one that Stillen remarkets. Brad's are
full 320mm rotors, the same used on
production Porsche race cars, and the OE
Porsche rotors are Porsche modified
Brembos.
I am not sure what
expectations the roadracers have with the brakes, but
when I raced bikes,
pads were toast after a weekend of hard racing. This is
with the best
hardware money can buy. Clearly bikes and cars have different
braking
requirements and abuse the brakes in different ways but I am sure
you see
what I am getting at.
I imagine your goals are the same, so I apologize
in advance if I am being
redundant. I'd like to suggest that
expectations be established ahead of
time since that will determine
specifications. Baer, for instance, can put
together the ultimate in
braking systems as I am sure could many others, AP
Lockheed goodies from KVR
coming to mind. Now you are talking at least
$3-5K US for rotors,
calipers, hangers, plumbing and probably master
cylinder. Also, to go
beyond 13" wheel fitment becomes an issue thus upping
the cost potentially by
quite a bit.
I'd love to see an effective and affordable braking package
for our cars
too. I just think there are practical limitations which
may come to odds
with expectations. I also think that the near ideal
setup is already
available, but I guess it would have to be tested under the
conditions you
encounter. I know putting together a test setup for
$1000 isn't exactly
pocket change, but maybe something like this would be
achievable with some
pulls and tugs here and
there?

For me, $1000 is tops for rotors, calipers and a set of
pads.
I'd be much happier with stock calipers, good rotors, and a set of
pads
that would last a weekend for less than $500.
But that's just
me.

The severity of wear of the pads could due to the quality of
the
cross-drilling on the rotors. I don't know the technical terms or
how
many types of cross-drilling there are out there.. just from my
own
experience.. my 1st set of X-drills were from the place called
Dynamic
Turbo.. they claim it was Brembo rotors.. when they arrived to my
door
steps.. they were clearly x-drilled stocks.. those rotors shave my
pads
like hot butter.. the x-drillings were always filled with pad
compounds
after a few hotlaps.. that also caused premature over heating..
i
always had to poke them through in the pits.. haha =)
On the other
hand.. Brembo/Stillen and Porterfield X-drillings didn't
eat up the pads like
that..

The Powerslots rotor hub actually separated

Whoops, I think
you misunderstood me. In Brad's kit, which by the way
is about $1500
last time I checked, only the calipers are OE
Porsche/Brembo. The
rotors are KVR. As far as I know, no one on any of
our lists has broken
a rotor by KVR or Porterfield.
Maybe Brad can join this discussion and
add his experience.

No, you need to be able to deliver more fuel but after 15psi the
injectors are
close to maxed out. To prevent detonation on higher boost you
must use the gas
to cool down the chamber. Your stock injectors will max out
and the ECU will
activate the fuel cut when trying to increase fuel with the
AFC. There is no way
around bigger injectors !

at least 16 ? )

Just
leave the turbos out of the discussion as with the appropriate fuel
mods
aou'll be able to run 18psi.
> ALSO : Since my car is a 1996
VR4, will it set off the OBDII software in my computer (

No, null problemo :)
My advice : Get an AFC (ask Matt Meyer,
Acc.Acc. directly), or look at the DSM
parts trader. I've seen them used
between $200 - $250. But it is of no use
without bigger injectors. Get a good
set of 560cc of any brand and finally get
the Walbro 290 l/hr pump. These
three parts together will cost you about $1100.
The BOV is not needed to
achieve the desired boost but use a good wideband
O2-sensor together with a
A/F meter to be able to tune in the AFC.
BTW, don't forget to regap the
plugs.
Hope this helps,

Team3S: Wide band O2 sensor ?
Unfortunately, the stock O2 sensors act
somewhat digital, rich or lean and they
do not have a large "hysteresis"
area.
To tune in our cars properly it would be interesting to know how
much rich or
how much lean the setting is. Fore this a good O2 wideband
sensor together with
an A/F meter would be very helpful.
I know
Autometer is offering one as well as Bosch but does anyone know if these
are
widebands and what the sensors usually cost ?
BTW, the ECU should not
have any problem with them.

Not really the cause !
Remember, the PowerSlots are slotted and this will cause
about 20% more pad
wear. The setup must be properly combined together. But I
always used a set
per day until I got the Pagids. They looked almost the same
after the last
day :)
> Stock rotors do not work. They get hot and warp.
Very
true. My horror story is the accident I had on the german Autobahn. It was
a
hot summer afternoon and I drove aroun 150+ mph and had to brake down
several
time. As the accident happend I felt a huge fading. With the brakes I
do have
now I'd been able to get behind the truck and not beside of
it.

But you

the

there.

Your problem number two. My
rear ones are also pretty hot after a day and I can
see some pad wear. Since
I installed the Bremsas to the rear too, I'm very happy
how straight the
Animal brakes under heavy conditions. I'm not sure about the 94
but what kind
of calipers do you have in the rear. The first gen had the
one-piston caliper
while the newer and EU cars got the stronger 2-piston types.
> I

No, a proportioning valve should nothing do
to the ABS. But with the proper
brake system I do not see a need for
this.
> 3. Install a water cooling system in the air ducts.
>

I'd keep my hands off this crap. Do you really think that the
water vaporizes ?
It doesn't vaporise on the windscreen and therefore not in
this duct. Using a
heavy pump and the right nozzle will do this but the water
will finally come to
the rotors as it will condense in the path. And this is
not good to the metal.
Heat the things up like hell and spray water on it can
warp them immediatly.
This is not the same like driving in rain as the
humidity and ambient is
different. Have you seen any racing car that needs
such stuff ?
For me it's clear that good rotors and pads are the things
you need at first. As
you don't want to spend the needed amount of money you
do not have a lot if any
option. You ask for a solution, there are many. But
there is no stopping without
taking money out of your wallet !
Things
to remember :
- - Crossdrilled rotors (drilled before finishing) tend to
crack and eat up pads
- - Slotted rotors "shave" the pads (20% more
wear)
- - Too big rotors and too much force can cause damage to the front
suspension
- - Big turbos give you more power - better brakes help to stop
this power
Both are about the same price, no way out :(
One
last idea : Why not buying wheels that shave air to the brakes like
a
windmill ? This would solve a lot of your problems :) Also slot the upper
part
of the fender to let air into them. This will also cool the tires a
little.

I'm sorry to sound that negative but you'll
never ever be able to get this stuff
for this price. Maybe you can organize a
GP on a good setup and the price will
drop to this with enough
contributors.

I'd say rotors for $1000 that should last about half a year when
racing a lot,
pads for $200 a set per weekend (1/2 in the rear) and braided
steel brake lines
for $280
Not too bad
IMHO.

Twice last year, once so far this year. I'd run more if I had the
money --
it costs $195 to enter, plus gas, hotel, meals, and brake pads. A
weekend
event can cost $500, because we have to leave on Friday to get there.
I'd
like to run about 4 events per year, hopefully at different tracks
around
the Midwest -- at RoadAmerica, Mid-Ohio, St. Louis International
and
Blackhawk Farms, for example.

Last year, the Performance Friction pads lasted the entire weekend
and
more. I changed to a compound that is more race than street, and these
631
pads only lasted three sessions. Of course, I was going faster.
Are
you saying the $200 Pagids will last an entire weekend and more? How
much
more?

How can that be? Doesn't the shield trap the
heat?
I can't get cooling air to the brakes with the shield in place because
it
blocks all access.
And I'm convinced that my ducts help considerably,
though obviously not
enough.>

I don't know if it's a one- or two-piston caliper, but
it is definitely
smaller than the front calipers. Do you think it's possible
to install a
set of big front calipers on the
rear?

A TransAm crew member suggested it. I agree that
injecting water directly
onto the rotor is a bad idea. But perhaps by
injecting water at the front,
the rapidly rushing air through the duct would
create an aerosol mist
(rather than a deluge), so it wouldn't be like
throwing cold water on a hot
disk. More like throwing cold, moist air. It
probably would work better at
high speeds than it would in slow corners,
because air flow would be much
greater at speed. Maybe it's suitable
only on long straights. I dunno.
That's why I posed the
question.

I don't want to spend $2700, that's for sure.
I also
hate to spend lots of money and get no results. We've heard horror
stories
right here on the list of guys spending $2000 and having rotors
crack. Brad's
$1500 Porsche system is sounding better all the time, but
even his KVR rotors
break. George Kuo's Porterfield rotors are looking
good at this point,
because they are stock rotors that have been heat
treated and then
drilled. Maybe a cost-effective combination would be
Brad's Porsche kit
with Porterfield rotors.
I think this discussion is actually getting
somewhere.
This is a great list.
