221 * 1.25 = 277 rounded up (Marketing privilege)

   They were not clear about what correction factor was appropriate,  
if any; the owner mumbled something about their dyno reading "20%  
below a dynojet", but Ned says the III+ is only 277hp, and if you use  
that plus a 1.25 multiplier (which Garrett of GIAC fame says is  
appropriate for virtually any quattro, based on his experience  
dyno'ing stock Audis for a baseline), then you're looking at 300+ hp,  
which is extremely doubtful.  With just the drivetrain loss  
mulitplier, peak HP was basically 266-267HP; given that the car  
received exactly zero checks before all this, that doesn't seem  
hugely unreasonable.  This particular dyno was an eddy-current,  
constant load, if I remember correctly.  Any words of wisdom on this  
subject?  Anyone else dyno'd 200q20vs?  There was talk of this last  
year I think, but I  don't remember if anything came of it.

I'm hoping to get charts from all three runs eventually Apparently,  
"three runs, we'll do air/fuel and boost for extra" translated into  
"we'll give you ONE chart of  your best of three PULLS, done in some  
funky 'shootout mode', and we'll do A/F, but no boost because if we  
do boost for you, everyone else will want it too, even though you're  
paying extra.  But we'll do boost for one guy anyway."  I made it  
clear on the "customer survey" I wanted all three sets of charts...

Hearing the car going full-bore was worth it though!
