Not really :) I'm sorry but sometimes I just
use the wrong words and it's
not that easy to explain something more or less
difficult in another
language.
If you drive on a cool day and you feel
the car has more power than usual,
then this is because the air is denser.
Therefore the sensor reads more air
volume sucked in, the pressure produced
by the turbos is cooler and the fuel
efficiency is better. Due to this more
air volume, the ECU adapts this and
increases the IDC to inject more fuel
that finaly produces more power.
On a hot day the ECU may dump fuel to
run way too rich just preventing any
retard due to knock. The fuel/power
relation in the Excel-Table is then
highly degraded and some fuel is just
wasted as coolant. The table is
assuming that there exists an optimal system
although the BSFC does help to
adapt for the specific type of
engine-system.
>> But this has nothing to do with the BSFC.

Hmmm. Seems to me it would be directly related.
Related to what ?
It's a constant and not a variable and is not related to
any ambient
figure.

OK, that makes

OK, here is my next question then :),
yep, I do have more. :)
It would seem likely then that if the
injectors simply are not
capable of supplying enough fuel to pass beyond the
400hp mark, (roughly),
and seeing as how, at 18psi I am still showing a rich
condition, and that we
believe that at 15psi the motor is making about 400hp,
would it not seem
logical that I should be over the 400hp mark? Which
leads me to believe
that my A/F gauge is showing me a pretty big lie.
Thoughts?

Team3S: Bleeder valve
I am going to attempt the bleeder valve
installation on my 94 VR4.
I've studied Roger's page, printed it out, and
compared it to my engine.
Two questions, because I can't quite make out
Roger's pictures, and I want
to be absolutely sure before I start cutting
hoses:
1. Where, exactly, is the stock solenoid valve? What does it
look like?
(hey, guys -- turbos are all new to me. I came here from
Corvettes. I don't
know a turbo solenoid valve from a pile of
rocks)
2. Looking down at the four-way H valve connection, from the
passenger side
of the engine, which is the line to the solenoid valve? (I
know, it's
essentially the same question: find the solenoid valve, and you
find the
right hose. But I'm the kind of guy who wears a belt and suspenders,
and
pins his shirt to his pants, just in case.)
Rich/old poop/more
horsepower!

Re: Team3S: Bleeder valve
The solenoid is on the firewall in the
center. It is the right most
solenoid in the group. The bleeder
goes on the bottom hose. Check out

for pictures
of a bleeder install.

What does it look
like?
==============================================================
On
the firewall, passenger side at the top of the engine compartment. there are
two
solenoids side by side, EGR and boost. Boost is nearest the
centerline of
the car [ page 8-17 electrical manual ]. It's a plastic box
about two inches high and
one inch wide with two vacuum hoses to it --- one
hose goes to the 'H' connector
and the other goes to the wastegate. One port
of the solenoid is vented to the
atmosphere, it may have a small filter cap
over it.
As to question two you're right, follow the line :-)
You'll have to do without the
suspenders in this
case.

Subject: Team3S: Toyo Tires
- Anyone have any experience with them?
After just 10000 miles, my
Pirellis gave up the ghost on my VR-4. The best
I've ever gotten is
20,000 miles on a set of Dunlops. The Pirellis gave me
good service
until about 8,000 miles then became very noisy and developed a
bad
vibration. Tired of spending thousands to keep rubber on the road!
I
don't push the car too hard and am not racing. Local dealer has some
Toyo's
for only $670 installed with lifetime balance etc. Anyone have
any
experience with these tires? Traction both wet and dry are as
important as
handling and noise. Maybe I'm looking for too much.
Comments?

Team3S: SSBC installation help
Hey guys, just got in from the garage and
had a few questions. (due to the
poor instructions provided by Blitz :-)
) Here is what I did. I removed
the stock solenoid and in it's
place I put the new blitz solenoid in. One
line has a white dashed line
on it that goes in front of the turbo, I am
assuming that is not on the
pressure side. ( it did not have a clamp on it
originally.) And then
the other line goes to the H connector and the
actuator. ( I am assuming this
line would have pressure when the turbo
spools up). I hooked the line
with the dashes to the "out" side of the
solenoid and the other to the "in"
side. Does this seem right to you? I
looked at Roger's site but I
am still confused. I thought the solenoid bled
pressure off of the line
going to the waste gates to keep them closed
longer. On Roger's diagram
it seems like the solenoid's "out" port does not
vent to the low pressure
side but rather runs to the waste gate. Wow I
think I am just confusing
myself more and more. Can someone clear this up
for
me?
Thanks,
Kevin Schappell
