Blow off plumbing (a tad long...)

[Dave Head <dhead@sundial.net>]

Trial fitted the new Samco hose today (replacement provided in one day -
free w/instructions to send back old one). Even with the blowoff port moved
inward, it is still a very careful trimming job due to the down angle of the
throttle body.  The hose is stiff and the right size, but trimming at an
angle is needed to get it to lay right. Then its right on the verge of too
large an opening. Also easier to trim a spot for the air temp sensor at the
other end - hose fits better on that end, with a bit more sealing room.

Decided to point the blowoff hose down about 45 degrees in front of the
intercooler - that way with the 90 degree blowoff I can come back over the
TB hose and into the inlet pipe at a nice down angle w/no chance of hose
kinking..

Took my spare inlet pipe (Ah - gotta love those junkyards!), drilled and
filed. Installed a Balkamp 3" long, one inch OD threaded water hose fitting
right about next to where the WOT switch connector is along the pipe. Bent
upward to a nice "directed at the turbo" angle after threading. Fitting came
from NAPA, part # avail if you wish . Decided to forego brazing the joint,
as I wanted to try a new high temp (250 degree) epoxy with Kevlar fibers.
Sitting curing as we speak...  All we need now is 14" or so of 1" ID hose, a
couple hose clamps, and a 'tee' fitting with vacuum hose for the control.
Should have it done for the weekend. The second Audi parts 'where the bucks
come from' job calls me on Thursday and Saturday... Then we can test run the
2 modified chips I've been sent to play with.  Heh, heh...

Even bought a new air filter (6.99) and fuel filter (23.99 - YIKES!) to
ensure max flow! I may even drop kick the tri-electrodes and try the
singles. Still getting an intermittent spark knock at high 1.6+ levels...
