a fellow on another forum did the test with his APR supercharged RS4 last week. His timing method used was
Vagcom log, which in my experience is a bit 'slower' than the stopwatch/speedo method. i.e. my car can do 8.2-8.3 seconds on the stopwatch/speedo with video, but is usually more like 8.5-8.6 on a
Vagcom log
anyway, here's his data on a 93 US octane tune (98 Europe octane) and a mix of gas that is probably more ike 95 octane (or around 100 Europe octane)
1st, he did it before the supercharger
Mods - piggies, JHM 91 octane tune, stock catback exhaust
8.19 seconds in
Vagcom 3000-8000
6 Celsius near sea level
Then, after the supercharger, still with piggies and stock catback exhaust. Everything else same (fuel, location) but temp was warmer (10 Celsius)
6.59 seconds
Here's his post:

Below are my times from 6 3rd gear pulls this morning. The No-SC runs were taken Jan 12th and had a lower temp advantage. Today it ~50F vs ~39.
Current setup with piggies and stock exhaust.
Picked up 1.6 seconds on average.
