[s-cars] 80tq: Dyno Results

Javad, While I can get to the www.80tq.com/dyno page, I'm not able for some
reason to access the dyno pdf.  The page just locks up on me when I've tried
clicking on the pdf file link.

Very nice numbers! Particularly appreciated is your documentation of the
"tweaks" and the results achieved, changes seen between each run.  As I
recall you paid a lot of attention to removing restrictions from, and
smoothing out the flow pattern and path from your intake to, through and
including your custom IC install.

I'm not so sure though about the results you describe for your friends
modified UrS4 @ 30 psi.  Those seem a little low for a modified car &/or 30
psi.  My guess would be a good part of your results vs. the 30 psi AAN
numbers you have are the result of the attention you've given you intake &
exhaust tracks.

Now that I THINK I may have a car back, I've attached a jpeg of a chart
showing 3 separate dyno pulls at 18, 21 and 23 psi of boost on an otherwise
moderately modified (at least by Hapersized Colorado mafia standards) 93 S4
AAN.  FWIW, I think (hope) that these numbers may be slightly better when &
if were able to further optimize the ECU.  Since the runs, we have remove
what I think was a significant "choke" point in the intake, and I'd hope if
we get the car back on a dyno we might see an improvement in the numbers and
onset of boost.

At 30 psi I would think your friend should be seeing more than 275 at the
wheels?  If there's any correlation in between the psi numbers, I would have
to suspect he's got a major flow restriction somewhere in his system that's
pressurizing up the manifold, but not letting the gasses out?  i.e. Working
hard, but not working well.

Could I get you to you email a copy of the pdf file directly?

~Well, its official - what a well tuned, good breathing (IOW, no
~CIS) Audi 10v
~car will do at 15psi.  See below:
~You can download a PDF of all 5 runs I did, I'd love to hear any thoughts.
