For more than 2 years now. This red thing I am driving is fast! Had
cranked it up to 20psi, was pulling like a locomotive (scared the hell
out of the likes of Probes and TransAms). With this much boost it was
pinging under full throttle in a hot day at a race track, had to back it
off. The decision was based on the equation 1I.A.=2TAP. Drove a coupe of
cars with the Ned's mods - VERY impressive! I have not decided on the
setup for my (hopefully) coming A4TQ this spring. I may go with I.A. to
try it out. Spoke with Ned at the Glen and was treated to a ride in his
'86 5000 20v with a bazooka sized muffler. Awesome! And I don't mean the
looks of his car; like he said "it ain't pretty".

It is an early '89 200 with a low compression MC engine with 1 knock
sensor and a large K26 turbo. That is why I was able to dial in this
much boost (on a cold damp day).

Yes it does.

Apparent as of yet. It takes years to find out that the Audi engine had
"only" lasted 200kmi, although could have been more. I am guilty on
using a 2870A Fram for several years on my previous cars. After I bought
a turbo I have finally started doing some recearch on the subject.
