[BiturboS4] Chipped: How to prepare. How many miles...

[John Chase]

Great!
>From the research I've done before you chip you should replace the
bi-pipe, the diverter valves and expect to replace your clutch. I do
know that the bi-turbo motors are a little touchy (hence Audi went with
a v8 in the new s4's), but how many miles are these motors really good
for...chipped or stock?

My mechanic installed it.  The O-rings looked fine when I pulled it
apart.  It's just that they are so small and don't have enough meat to
seal between the throttle body and the bi-pipe.  So I used 3 instead of
2.  If you have one take a good look and you'll know what I'm talking
about.  If you need extra O-rings I have them and mail them to anyone
that asks.

Cheers,

Tuan

Be very careful with the APR bi-pipe.  It's a nice product but can leak
as well.  Make sure you do a pressure test after the installation.  My
bi-pipe leaked at the throttle body.  I had to purchase more O-rings and
used 3 instead of 2 to make sure it sealed.

Were you chipped?

P.S.

I heard from a reliable source that the LOUD turbo noise if from a
broken Y-pipe right on top of the motor. It gets ripped and then the
turbo over compensates for the air leakage and your turbos are WAY over
worked. Solution: replace Y-pipe with an aftermarket solution (apr makes
a good replacement).

On the way home last night...
moderate to hard(er) acceleration, a little lurch and
boof!!! huge cloud of smoke out the back.
no turbo whine warning, just let go, or
at least I am assuming it is a turbo or related gasket.
Oil level was zip in no time and dripping out the tailpipe
also dripping under RH side of engine. I'm freaking because when it
went, I was on a bridge and couldn't safely pull over. Had to drive a
bit w/ oil warning on and I'm praying I didn't F-up the top end also.
NOT a good day!!

Damn kicker is the car has 42K but is over warranty in
time. I am hoping to work the 50/50 deal or talk to Todd
and just do it (right), but this is unexpected and 10K would
be a bit much to scratch up on short notice....
