Z4 *Official* Dyno Thread

I think it'd be really helpful if we got an official Dyno thread going. For ease of comparability, let's keep it simple:
  1. Year, trim, motor
  2. Dyno type - Peak HP & TQ
  3. Mods (e.g. software, exhaust, intake, etc)

Both Dynojet runs at same facility (Auto Authority in New Haven, CT). Figures above are SAE 5 corrected. Dip around 7200 rpm is from DSC issues which have been sorted since then. Planning to go back in a month to do one more run before season officially begins.

I had the ECU reflashed and showed a small loss of peak power on the dyno. Can not find the dyno sheet.

I think it was 238hp/228tq.

But the increased redline and power delivery feels great.

I have not been to the dyno in over 2 years, and I'm trying to get back into modding this car.

Went out and got a 3:73 diff last week (have not installed it yet)

Maybe get Headers and MILV's

Very nice, do you happen to have the graph with SAE and smoothing?

Don't think so, let me check my old emails.
