see that. i like to call that an "assumption".
i recall you from way back in february when i
started trying to get my head around some of the
type44s design strengths and flaws. you were the
one that accused me of being ricey and attacked
me for wanting to lower my car.
of the many things that were said in your email
reply to me, you said that you reserved the right
to laugh at me when bad things happened to me.
well, bad things have happened to me, and they've
not been because i just jumped the gun and upped
the boost. it was done in such a way that fuel
and air in proper measure were present at all
i did NOT do the zener diode mod. i asked about
it, and while i managed to get the resistors, i
still have yet to get a 4.3V zener diode. it
sounds like a very good way of getting power, and
i'm sure that it would have worked fine.
however, i went another route. check the
archives. i made mention of it before.
a friend of mine has been a vw/audi mechanic for
about 25 years now, and had much luck tuning the
10VTs back in the late 80s and early 90s. my
digital gauge showed me that it was putting out
2.0BAR of boost, with some peaks at 2.1BAR before
the head gasket failed completely.
he drove his test car for 250,000km with the same
mods that i have in mine. never ever did his
head gasket fail. the car was eventually
scrapped because it rusted away. i trust his
judgement implicitly because he has proven his
knowledge time and time again to me and to his
many loyal customers.

the head gasket gave out where the head was
marred during it's reinstallation. while a total
PITA, it's an understandable occurence because of
the weight and awkwardness of both the head
assembly, and the small area that it needs to be
the cheque was in the mail on this one. if 2
days @ 19psi didn't do it, then 30 days at 8psi
probably would have.

i sincerely thank you for this information.
however, my ARP studs are on their way, so i
think that this tool will not be necessary.
here's the thing, i'm here for information. i
want to learn. i want to know how large of a
smile a 10VT can paint on my mug. if you can
offer info, then i thank you.
however, if you feel the need to preface you help
with pointless attacks on me, then please don't
bother. i have been more than civil the first
time you attacked me, and now this time. do we
need to do this again?
