DMM Dyno Day 20020316

Dyno Day 20020316 - Data

Below is a chart with the 10 Minis that took part in this happening, together with the expectancies, outcome, charts & graphs and the comment of the operator on where some improvement might be found. Some of the data was 'nicked' from Eric site.

The session for each Mini consisted of 4 runs.
The 1st (*.001) was a run in 3rd gear,
the 2nd (*.002) a run in 4th gear,
the 3rd (*.003) a run in All gears ('change up') and
the last (*.004) a Fast acceleration test were the engine is accelerated about 500rpm, then released for about 1000rpm and then again accelerated.

As mentioned, a (IMO very big) bonus was that we also got the test-data emailed, which can be analyzed with an app from DynoJet, the people that made the test-bench. Most of the graphs you see on these pages are derived from that application. It also means that if you'd like to see another graph, all you have to do is ask (and probably wait a while :). Unfortunately there is no international version of the app so no kW, km/h or Nm graphs are available (to me).

The graphs are in RPM vs Power (DIN HP) and Torque (DIN ft-lbs) as measured at the wheels.
To convert various auto-motive figures, use this very useful page.
